How are the atoms of carbon different from the atoms of nitrogen
Per my research, it was said that each of the atoms of the carbon has over 6 protons, six neutrons, and 6 protons. Each atom of nitrogen has 7 protons, 7 electrons, and 7 neutrons. The atomic mass of carbon and nitrogen is 12 and 14 respectively. As the number of electrons in the atoms of the two elements is different they have different chemical properties.
Explanation:As you may know, I did my research and this is what it gave me. I would suppose it is correct since it explains that the carob has over 6 protons and so on. Correct me if I am incorrect and I hope this helped. Have a good one!

Answer:
18. E. 0%
19. D. 25%
Explanation:
Question 18:
Let's use "B" to represent the dominant allele of "light blue skin", and
"b" for recessive "light green skin".
Squidward => BB - light blue skin
Squidward's bride => bb - light green skin
When they cross, they will have the following offsprings:
(BB) × (bb) - Parent
(Bb) (Bb) (Bb) (Bb) - Offspring
All the offspring would be light green skin. The dominant allele of light green skin will express itself over the recessive allele.
Therefore, the chances of Squidward and his bride having light green skin is 0%
Question 19:
Squidward's son => Bb - light blue skin
Squidward's son's bride => Bb - light blue skin
(Bb) × (Bb) - parent
(BB) (Bb) (Bb) (bb) - offspring
They will have the following offspring:
BB and Bb - light blue - 75%
bb - light green - 25%
Chance of having offspring with light green skin is 25%
Need help with this please help ASAP
Answer:
The correct answer would be -
17. 50% chances of round offspring
18. 25% chances two copies of dominant allele in the genotype of offspring
Explanation:
17. In this question it is stated that the Spongebob is heterozygous and has a square body which means the square body is dominant over the round that is present in sponge Susie that means she has two copies of the recessive allele.
S for square trait and s for a round trait then
S s
s Ss ss
s Ss ss
Thus, the correct answer is 50 percent as there are only two copies of ss.
18. in this question Patric and Patti both have heterozygous for the pink (P) body-color dominant over yellow (p). The chances for the true-breeding dominant genotype would be -
P p

1.Which of the following would decrease the rate of a chemical reaction?
A Increase the temperature
B Reduce the concentration of a reactant
C Increase the concentration of a reactant
D Add a catalyst
Answer:
d.) add a catalyst
Explanation:
ae per I know this is Ur , but I am not sure so u check it
B. Reduce the concentration of a reactant
A chemical reaction is a process that leads to the chemical transformation of one set of chemical substances to another.When the surface area of reactants is more the sites available for the collisions increase. More collisions between the reactants increases the rate of a chemical reaction. Decreasing the surface area of reactants decreases available site for collision. This eventually decreases the rate of a chemical reaction.To decrease the rate of a chemical reaction, B. Reduce the concentration of a reactantFor more information:

The half-life of a strontium isotope is 25 years. How much of this particular isotope will remain after 100 years if the starting mass is 16 grams?
Answer:
1 gram
Explanation:
Half life = 25 years
Starting mass = 16 grams
Time = 100 years
Number of half lives = Time / Duration of Half life = 100 / 25 = 4
After first Half life;
Remaining mass = 16 / 2 = 8 g
After Second Half life;
Remaining mass = 8 / 2 = 4 g
After Third Half life;
Remaining mass = 4 / 2 = 2 g
After Fourth Half life;
Remaining mass = 2 / 2 = 1 g

You come across an article in a scientific journal from 50 different laboratories around the globe that measured the boiling point of water and discovered that it is 100°C everywhere.
What transpires when water is heated to 100 C (This is 212 F)?Water turns into gas around 212°F (100°C), which is the temperature at which it begins to boil (water vapor). Pressure affects the melting/freezing and boiling points. Water's boiling point changes when air pressure changes. The boiling point decreases with increasing altitude or decreasing pressure.
At 212 degrees Fahrenheit, does water boil, or at 100 degrees?Water has a freezing point of 32 degrees Fahrenheit and a boiling point of 212 degrees Fahrenheit on the Fahrenheit scale.

Sulfur hexafluoride, SF6, is a colorless, odorless, very unreactive gas. Calculate the pressure (in atm) exerted by 2.02 moles of the gas in a steel container of volume 6.21 L at 70 ℃.
Answer:
9.15 atm
Explanation:
Ideal gas equation of state PV=nRT
P in hPa, V in L, n in mol, R is a constant which is 83.1 hpa*L/mol*k, T in kelvin.
Plug in all the number, and we will get:
P*6.21=2.02*83.1*343
P =9271.6(in hpa)=9.15 atm
Determine how many moles of water (H2O) are formed from the combustion of 7.50 x 1023 molecules of propane (C3H8). 1 C3H8 (g) + 5 O2 (g) ⟶ 3 CO2 (g) + 4 H2O (g)
Answer:
4.98 moles of H₂O
Explanation:
The balanced chemical equation for the combustion of propane is:
C₃H₈ (g) + 5 O₂ (g) ⟶ 3 CO₂ (g) + 4 H₂O (g)
That means that 1 mol of propane (C₃H₈) produces 4 moles of water (H₂O).
We know that 1 mol is equal to 6.022 x 10²³ molecules. So, we convert the molecules of propane to moles as follows:
7.50 x 10²³ molecules C₃H₈ x 1 mol/6.022 x 10²³ molecules = 1.245 mol C₃H₈
Now, we use the stoichiometric ratio 4 mol H₂O/1 mol C₃H₈ derived from the chemical equation to calculate the moles of water produced:
1.245 mol C₃H₈ x 4 mol H₂O/1 mol C₃H₈ = 4.98 mol H₂O
Ethanol, C2H5OH, is manufactured on a large scale for a wide range of uses such as alcoholic drinks, as an industrial solvent and as a raw material for the synthesis of many organic compounds. Ethanol, C2H5OH, is manufactured on a large scale by two methods: • Fermentation, using yeast, of sugars, such as glucose, C6H12O6. C6H12O6(aq) 2C2H5OH(aq) + 2CO2(g) The ethanol is then distilled off. • Hydration of ethene, C2H4, with steam in the presence of an acid catalyst. C2H4(g) + H2O(g) C2H5OH(g) Compare the sustainability of these methods of manufacturing ethanol in terms of: • availability of starting materials and energy requirements; • atom economy. In your answer, you should make clear how the atom economy of the processes links with chemical theory.
Answer:
See explanation
Explanation:
In considering the sustainability of the two processes, we must remember that fermentation involves the use of sugars as raw materials. These sugars are grown naturally as plants from which sugars are extracted for the fermentation process. This is a sustainable process because sugar is a renewable resource.
On the other hand, ethene is produced from the cracking of fractions obtained from distillation of natural gas and oil. Natural gas and oil are not renewable resources hence the process is not sustainable. The cracking of ethene requires a lot of energy compared to the fermentation of sugar.
As regards atom economy, the cracking of ethene, C2H4(g) + H2O(g) ------> C2H5OH(g) has a better atom economy compared to the fermentation of sugar; C6H12O6(aq) -------> 2C2H5OH(aq) + 2CO2(g).
Atom economy has to do with the process of designing reactions in such a way that atoms which are in the starting materials end up in the final product and not as waste materials.
Fermentation produces a waste material which is CO2 while the cracking of ethene produces no waste material. All atoms of the reactants are converted into atoms of products.
Hence, the cracking of ethene displays 100% atom economy. This implies that all reactant atoms are found in the desired product.
