The effect of carbon dioxide that is coming out of volcanoes can be global warming.
Effect of carbon dioxide:CO2 has been demonstrated to be a critical supporter of air contamination, playing a significant job in the greenhouse effect. That is on the grounds that carbon dioxide traps rays at the ground level, bringing about ground-level ozone. That keeps the earth from cooling during the evening and warms sea waters.
More carbon dioxide in the atmosphere will lead to global warming.

2NaHCO3(s) → Na2CO3(s)+CO2(g)+H2O(ℓ)
If the chemical reaction above is occurring, we would likely observe...
Question 14 options:
Increase in CO2 (g) over time.
No NaHCO3 (s) will be left after a time.
Increase in NaHCO3 (s) over time.
Decrease in Na2 CO3 (s) over time.
Answer:
Increase in CO2 (g) over time.
No NaHCO3 (s) will be left after a time
Explanation:
The reaction, shown below;
2NaHCO3(s) → Na2CO3(s)+CO2(g)+H2O(ℓ) is a decomposition reaction. A decomposition reaction is a kind of chemical reaction in which a given chemical specie breaks up to give other chemical species. Decomposition may be induced by heat or light.
Usually, there is only one reactant in a decomposition reaction; the specie that disintegrates into the products. This reactant usually decreases in concentration steadily because it is converted into products. This is why the mass of NaHCO3(s) in the system continues to decrease steadily until it finally falls to zero.
Conversely, the concentration (for aqueous) or volume (for gases) or mass (for solid) products of the reaction increases steadily as the reaction progresses. This explains why the volume of CO2 in the system will steadily increase over time.

12. How many grams of glucose (C6H1206) is produced if 17.3 mol of H20 is reacted according to this
balanced chemical equation? 6CO2 + 6H20 - C6H12O6 + 602
13. Nitroglycerin (C3H5(ONO2)3] is made by reacting nitric acid (HNO3) with glycerol [C3H5(OH)3]
according to this reaction:
C3H5(OH)3 + 3HNO3 - C3H5(ONO2)3 + 3H20
If 87.4 g of HNO3 is reacted with excess glycerol, what mass of nitroglycerin can be made?
Answer:
1. 17.3 MOLES OF WATER WILL PRODUCE 518.4 G OF GLUCOSE.
2. 87.4 G OF HNO3 WILL PRODUCE 7.86 G OF NITROGLYCERIN WHEN REACTED WITH EXCESS GLYCEROL.
Explanation:
1. How many grams of glucose is produced from 17.3 mole of water?
Equation:
6CO2 + 6H20 ------> C6H12O6 + 6O2
From the reaction, 6 moles of carbon dioxide reacts with 6 moles of water to produce 1 mole of glucose
So therefore,
6 moles of water = 1 mole of glucose
Since 17.3 mole of water was used, we can first calculate the number of moles of glucose produced:
Then, we have:
6 moles of water = 1 mole of glucose
17.3 moles of water = ( 17.3 * 1/ 6) moles of glucose
= 2.883 moles of glucose
So we say 17.3 moles of water produces 2.883 moles of glucose
At standard conditions, 1 mole of a substance is its molar mass
Molar mass of water = 18 g/mol
Molar mass of glucose = 180 g/mol
From the reaction:
17.3 moles of water produces 2.883 moles of glucose
17.3 * 18 g of water produces 2.833 * 180 g of glucose
= 518.94 g of glucose.
From 17.3 mole of water, 518.4 g of glucose will be produced.
2.
C3H5(OH)3 + 3HNO3 -------> C3H5(ONO2)3 + 3H20
3 moles of HNO3 reacts to produce 1 mole of nitroglycerin
Molar mass of HNO3 = ( 1 + 14 + 16*3) = 63 g/mol
Molar mass of nitroglycerin = ( 12 *3 + 1 *5 + 16*6 + 14*3) = 179 g/mol
3 moles of HNO3 = 1 mole of nitroglycerin
3 * 63 g of HNO3 = 179 g of nitroglycerin
if 87.4 g of HNO3 were to be reacted, we have:
189 g of HNO3 = 179 g of nitroglycerin
87.4 g of HNO3 = ( 87.4 * 179 / 189) of nitroglycerin
= 7.86 g of nitroglycerin
So therefore, 87.4 g of HNO3 will produce 7.86 g of nitroglycerin when reacted with excess glycerol.

Consider this hydrocarbon. A hexagon. Is this an aromatic hydrocarbon? Why or why not? Yes, because the carbon chain is made up of single bonds. Yes, because the carbon chain is ring shaped. No, because the carbon chain is composed of only a single ring. No, because the carbon chain has no double bonds.
Answer:
C. No, because the carbon chain is composed of only a single ring.
Polycyclicity, having more than a single ring, is a property of only aromatic hydrocarbons. Therefore, if the hydrocarbon is not polycyclic, it is non-aromatic
Explanation:
Cyclic Hydrocarbons
These are organic compounds which are cyclic in structure. The compound cyclohexane involves a ring of six carbon atoms, each of which is also bonded to two hydrogen atoms
Aromatic hydrocarbons are cyclic ring organic compound which are based on the benzene ring structure.
A. If the hexagon contains single bonds, it is non-aromatic.
B. No. Having a ring shape does not on its own determine the aromaticity of a hydrocarbon.
C. Polycyclicity, having more than a single ring, is a property of only aromatic hydrocarbons. Therefore, if the hydrocarbon is not polycyclic, it is non-aromatic
D. Having double bonds within a ring is not a criteria for being aromatic. Both aromatic and non-aromatic hydrocarbons have double bonds within their rings. However, aromatic hydrocarbons have alternate double and single bonds within their 6-carbon ring structure.
Note: Since the structure of the required hydrocarbon is not shown, the explanation contains attachments of hexagonal structures of three hydrocarbons; one non-aromatic and the other two are aromatic. Cyclohexane is non-aromatic while Benzene and the polycyclic compounds are aromatic.

According to A pex, the answer is B.
Explanation:
Because its right.
When one reactant breaks down to form more than one product is a decomposition reaction. Therefore, option (B) is correct.
What is a decomposition reaction?A decomposition reaction can be described as a reaction in which a compound breaks down into two or more simpler compounds. The general form to represent a decomposition reaction is:
AB → A + B
Most decomposition reactions need input energy in the form of light, heat, or electricity.
Binary compounds can be described as compounds made of just two elements. The simplest type of decomposition reaction is when a binary compound dissociated into its elements. For example, Mercury (II) oxide decomposes when heated to form mercury and oxygen gas.
2HgO(s) → 2Hg (l) + O₂(g)
A reaction is a decomposition reaction even when one or more of the products are compounds. For example, calcium carbonate decomposes into carbon dioxide gas and calcium oxide.

PLZ HELP!! I WILL GIVE BRAINLIEST!! 50+PTS!! PLZ HELP!!!! In an exothermic reaction at equilibrium, what is the effect of lowering the temperature? A. The reaction makes more products. B. The reaction makes more reactants. C. The reaction is unchanged.
Answer:
A. your reaction makes more products.
Explanation:
This is a fun question dealing with idea of Le Chatelier's principle.
In an exothermic reaction, you produce heat. This means that heat will act as a product (or be on the product side).
Suppose there's an imaginary equation:
A + B -----> C (Now if I lower the amount of B, the equilibrium will shift to left to make up the lost B, or to bring the system back to equilibrium)
Apply the same concept as above below:
A + B -------> C + Heat (as I mentioned, since this is exothermic reaction heat is written as product, so if you lower the temperature, which means basically lower the heat, the reaction will shift towards right to make up the lost heat, in this process you will make extra C which is products. Thus, your reaction makes more products.
Answer:
reaction makes more product

Answer:
The correct answer is C:
Kumho Tire Co. Ltd V. Daubert
Explanation:
In this case, the appellant (Daubert) has sued Kumho Tire Co. Ltd (the defendant) when 3 months prior the right rear tyre of his car exploded while the car was in motion killing a passenger and injuring others severely.
The appellant employed the services of an expert who had worked for 10 years with Michelin to give his opinion as having studied the attributes of the tire technology.
In a counter-argument, the defendant rather than dispute the opinion of the expert urged the court to exclude it as evidence because his methodology didn't conform to the requirements of the Law as given in Rule 702 of the Federal Rules of Evidence.
True to the defendants' position, the Law by the ruling in Daubert v Merrell Dow Pharmaceuticals required that for the opinion to count, it had to be scientifically correct. It was hence excluded as evidence in the case.

Answer:
Option B. 4.5g
Explanation:
The balanced equation for the reaction is given below:
2Na + 2H2O —> 2NaOH + H2
Next, we shall determine the mass of Na and the mass of H2O that reacted and the mass of H2 produced from the balanced equation. This is illustrated below:
Molar mass of Na = 23g/mol
Mass of Na from the balanced equation = 2 x 23 = 46g
Molar mass of H2O = (2.02x1) + 16 = 18.02g/mol
Mass of H2O from the balanced equation = 2 x 18.02 = 36.04g
Molar mass of H2 = 2.02 x 1 = 2.02g/mol.
Mass of H2 from the balanced equation = 1 x 2.02 = 2.02g
From the balanced equation above,
46g of Na reacted with 36.04g of H2O to produce 2.02g of H2.
Next, we shall determine the limiting reactant. This is illustrated below:
From the balanced equation above,
46g of Na reacted with 36.04g of H2O.
Therefore, 120g of Na will react with = (120 x 36.04)/46 = 94.02g of H2O.
From the calculations made above, we can see that it will take a high mass of H2O i.e 94.02g than what was given i.e 80g to react completely with 120g of Na. Therefore, H2O is the limiting reactant and Na is the excess reactant.
Finally, we shall determine the mass of H2 produced from the reaction as follow:
The limiting reactant will be used in this case as it will give the maximum yield of H2 since all of it is used up in the reaction.
From the balanced equation above, 36.04g of H2O reacted to produce 2.02g of H2.
Therefore, 80g of H2O will react to produce = (80 x 2.02)/36.04 = 4.5g of H2.
Therefore, 4.5g of H2 is produced from the reaction.
