Answer:
False grams is not used
Explanation:
IDEAL GAS LAW
The ideal gas law states that PV = NkT, where P is the absolute pressure of a gas, V is the volume it occupies, N is the number of atoms and molecules in the gas, and T is its absolute temperature.
It is necessary to use Kelvin for the temperature and it is conventional to use the SI unit of liters for the volume. However, pressure is commonly measured in one of three units: kPa , atm , or mmHg . Therefore, R can have three different values.
Answer:
<em><u>spontaneous composition</u></em> is the ingnition
of the substance due to the repid oxidation of its on material.
There is no requirement of heat of external sources.
<em><u>Rapid composition</u></em> on the other hand release large amount of heat and light energy.
Explosion and the firecracker is the best example of Rapid composition.
When you dissolve an ionic compound into water, the have a tendency to separate from each other. They're still chemically the samething.
LiOH is an ionic compound. Lithium is positive and "borrows" the hydroxide's negative charge to be neutral & vice-versa. When LiOH is dissolved in water the Lithium and the hydroxide separate into their respective forms, also known as ions.
So, LiOH dissolves to become these ions in solution= Li+ and OH-
(the plus and minus represent their charges).
Hope that helps!
