Always use least amount of sig figs possible. So this 9.7 would be (answer): 2 sig figs
Chemistry developed from alchemy after the 1700s. It was the Alchemist <span>observations and accidental discoveries that brought around modern chemistry.</span>
Since we are already given the balanced equation:
→ 
We can derive the molar ratios as: 1:2:1:1
That being said, we are given 0.172 moles of bromine (
), so it has a ratio of 1:1 with sodium bromide (
).
So we can take from that ratio, that when 0.172 moles of bromine are used, we are, in turn, going to get 0.172 moles of sodium bromide produced.
Answer:
Constant pressure of gas must have a constant volume and a constant number of moles of gas. It's equation is the ideal gas law: pV=nRT
Explanation:
The gas state is the most excited state. It doesn't have a definite volume or shape which is why it can be compressed. Gas pressure is basically the result of all the gas particles moving around and colliding against each other and their container. The rate this happens at as well as its force determines the pressure. Since there are many, many of these gas particles in all quantities of gas, the fluctuation of this rate as well as its intesity is nearly constant.
