Answer: Metals
Explanation:
When an atom accepts an electron negative charge is created on atom and is called as anion.
When atom loses an electron positive charge is created on atom and is called as cation.
The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.
Thus metals form cations.

Calamine solution contains zinc carbonate and is basic in nature. When applied in the skin, it reacts with the acid, and neutralizes its effect, thus giving relief.
What pressure, in torr, would a sample of Xenon exert if it were compressed from 4001 mL to 3002 mL at constant temperature, given that initially the pressure was 750.1 atm?
Answer:
759779.6 torr
Explanation:
Initial volume, V₁ = 4001 mL
Final volume, V₂ = 3002 mL
Initial pressure, P₁ = 750.1 atm
We need to find the final pressure at a constant temperature. Let it be P₂. [tex]P_1V_1=P_2V_2\\\\P_2=\dfrac{P_1V_1}{V_2}\\\\P_2=\dfrac{750.1\times 4001 }{3002 }\\\\P_2=999.71\ atm[/tex]
We know that,
1 atm = 760 torr
So,
999.71 atm = 759779.6 torr
Hence, there will be 759779.6 torr pressure.
what is the molecular shape of N2O2?
Answer:
If you're just looking at the Lewis Structure from the perspective of the octet rule, it does appear that the structure is correct. Dinitrogen always has a lone pair of electrons which could conceivably be used for dative bonding as you suggest. So from that perspective there appears to be nothing wrong at all - other than that it doesn't exist in nature in this way.

kinetic energy is1/2mv^2Aluminum cookwar cannot be used in cooking acidic food .Why?It is possible to clean an aluminium pot using an oven cleaner contaning sodium hydroxide?Explain.
Answer:
See explanation
Explanation:
Aluminium is an amphoteric metal. This means that it reacts with both acids and bases. This property of aluminium is important in the discussion below.
Aluminium cookers can not be used to cook acidic food because it will react with the food and this is not good both for the food and the cooker.
Also, It is not possible to clean an aluminium pot with sodium hydroxide because the sodium hydroxide will react with the pot yielding hydrogen gas since aluminium is amphotheric as follows;
2Al + 2NaOH + 2H2O → 2NaAlO2 + 3H2
Aluminum has been the metal of group 13 of the periodic table. Aluminum has been reacting with capability with both acids and bases.
A. The acidic food has not been cooked in the aluminum wares with the ability of Aluminum to react with the acid of the food and change the chemical composition.
B. The aluminum can react with the bases and acids. The reaction of aluminum with NaOH has resulted in the liberation of hydrogen gas with the formulation of sodium tetrahydroxoaluminate.
The compound has been easy to clean, and thus NaOH solution is used for cleaning and etching of aluminum.

How many moles of H2O form when 4.5 moles O2 reacts?
Explanation:
Start with a balanced equation.
2H2 + O2 → 2H2O
Assuming that H2 is in excess, multiply the given moles H2O by the mole ratio between O2 and H2O in the balanced equation so that moles H2O cancel.
5 mol H2O × (1 mol O2/2 mol H2O) = 2.5 mol O2
Answer: 2.5 mol O2 are needed to make 5 mol H2O, assuming H2 is in excess.

What causes one water molecule to stick to another water molecule?
Answer:
Hydrogen Bonds Make Water Sticky
Explanation:
This sticking together of like substances is called cohesion. Depending on how attracted molecules of the same substance are to one another, the substance will be more or less cohesive. Hydrogen bonds cause water to be exceptionally attracted to each other. Therefore, water is very cohesive.
why do atoms combine to form compund?
Answer:
See below
Explanation:
The following reasons tell why atom combine to form compounds:
1) They want to follow octet or duplet rule and attain the noble gas configuration.
2) They combine to form compounds because of the electrostatic attraction between them.
3) They form compounds to lower their energy and to become stable.

~AH1807would the pressure exerted by the gas in the tank would increase if the scuba tank were to increase in temperature?
Answer:
In fact, a full scuba tank will gain about 5-6 psi for every degree of temperature increase. This is one reason that full tanks should not be left in a hot trunk of a car. A tank filled to 3000 psi could easily reach 3500 psi if the temperature of it increased substantially.
eye is an organ why????
Answer:
The eye is an organ that detects light and sends signals along the optic nerve to the brain.
Explanation:
In humans, the eye is a valuable sense organ that gives us the ability to see. It allows for light perception and vision, including the ability to differentiate between colors and depth.Although small in size, the eye is a very complex organ. The eye is approximately 1 inch wide, 1 inch deep and 0.9 inches tall. The human eye has a 200-degree viewing angle and can see 10 million colors and shades. Humans have two eyes which allows us to have better depth perception and binocular stereopsis.

Which energy transformation takes place when using a power drill?
A.
mechanical to chemical
В.
electrical to mechanical
с.
chemical to electrical
D
heat to mechanical
Answer:
the answer is B
Explanation: Trust me I took the test
The correct option is option B which is electrical to mechanical.
When using a power drill, the energy transformation that occurs is from electrical energy to mechanical energy. The power drill is powered by electricity, which is converted into mechanical energy to rotate the drill bit and perform the desired work. The electrical energy is converted into the mechanical energy of rotational motion.
Hence, the correct option is option b

Alesha, Kayden,Leo and Caroline are lab partners. They completed the lab in which they put a small marshmallow in a closed, see-through container. They then pushed a plunger down to decrease the volume of the container. They observed the marshmallow looking squished and crumpled. For their lab write up, they must identify the relationship between volume, temperature and pressure of a gas to explain what they saw during this experiment. Determine which student is correct from the statements below.
A.
Alesha says the lab showed that when volume is decreased, pressure is increased. The increase in the pressure in the container is what made the marshmallow look squished and crumpled.
B.
Caroline says the lab showed that when volume is increased, pressure is increased. The increase in the pressure in the container is what made the marshmallow look squished and crumpled.
C.
Kayden says lab showed that when volume is decreased, temperature is increased. The increase in the temperature in the container is what made the marshmallow look squished and crumpled.
D.
Leo says the lab showed they increased the temperature of the container by breathing on it and decreased the volume by pushing down the plunger. Both of increasing the temperature and decreasing the volume caused the pressure to decrease and make the marshmallow look squished and crumpled.

A sample of carbon dioxide gas (CO2) contains 8.551 x 1025 molecules. How many moles of carbon dioxide does this represent?
Answer:
142.0 moles CO₂
Explanation:
To answer this question, we first need to know what a mole is. A mole represents [tex]6.022 \cdot 10^{23}[/tex] of something, and in this case, that something is molecules.
So, to convert [tex]8.551 \cdot 10^{25}[/tex] molecules into moles, we need to use the conversion factor [tex]1=\frac{6.022\cdot 10^{23} \text{molecules} }{ \text{1 mole}}[/tex].
Doing so (using dimensional analysis) gives us:
[tex]8.551 \cdot 10^{25} \text{ molecules } \cdot \frac{\text{1 mole}}{ 6.022\cdot 10^{23} \text{ molecules} } = \frac{8.551 \cdot 10^{25}}{ 6.022\cdot 10^{23}} \text{ moles CO}_2 = \\ \\ 141.996 \text{ moles CO}_2 = \boxed{142.0 \text{ moles CO}_2 }[/tex]
