All chemical reactions have a conversation of mass and energy.
Because:- There are only two laws for conversation in a chemical reaction. The conversation of mass, no mass can be created nor destroyed. Also, the law of conversation of mass states that no energy can be created nor destroyed in a chemical reaction. The charge can obviously change because they can bond and change charges.
The answer is A because The fact of temperature on volume changes of substance.
- Unsaturated fats include double bonds that provide structures that prevent development of tightly bonded compounds.
- The characteristics of the phospholipid head and tails determine how the phospholipids are arranged in the bilayer cell membrane.
This is why even though Olive oil and butter both contain fats, olive oil is liquid at room temperature and butter is solid.
- Since saturated fat makes up the majority of butter, it is solid at room temperature.
- Olive oil is an unsaturated fat since it is liquid at room temperature.
- Through hydrogenation processes, an unsaturated fat can be converted to a saturated fat.
<h3>What are saturated fats?</h3>
- a form of fat believed to be less healthy in the diet than unsaturated fat because it contains a higher percentage of fatty acid molecules lacking double bonds.
- butter, ghee, suet, lard, coconut oil and palm oil, cakes, biscuits, fatty cuts of meat are some of the examples.
<h3>What are unsaturated fats?</h3>
- a form of fat that is thought to be healthier in the diet than saturated fat because it contains a high percentage of fatty acid molecules with at least one double bond.
- Olive, peanut, and canola oils, Avocados, Nuts such as almonds, hazelnuts, and pecans, Seeds such as pumpkin and sesame seeds are some of the examples.

We use the ideal gas equation in order to calculate the temperature of the system. It is expressed as follows:
PV=nRT
where P is pressure, V is volume, n is the number of moles, R is the universal gas constant and T is the temperature.
15 atm (.1 L) = 0.5 mol (0.08206 L-atm / mol-K) T
T = 36.56 K
Hope this answers the question. Have a nice day.
2n² rule:
This rule is used to determine number of electrons in particular shell.
n=1 means K shell
n=2 means L shell
n=3 means M shell
n=4means N shell
The first K shell can hold upto 2 electrons, L shell can hold up to 8, third M shell can hold up to 18and the fourth N shell can hold upto 32 electrons. This rule of arrangement of electrons according to the shell is known 2n2 rule where n means number of shell.
For example: There is one proton in the nucleus of hydrogen atom, which moves in K shell path. It has no neutron.
