Answer:
.67 L
Explanation:
.030 mol x 22.4 L / 1 mol = .67 L
22.4 was used because that is what 1 mol equals for a gas at stp.
I think it's coal as you use it for bbqs and train drivers use coal too. I'm pretty sure it's coal, but I'm not 100% sure. Hoped this helps.
First we start with the given which is 89.0g of KCLO3 then we divided that by the molar mass of KCLO3 which is 122.55 g. After that we multiple it by the Avogadro's number which is 6.022*10^23. The answer is 4.4*10^24 moles of KCL.
Answer: C. The number of collisions of gas particles decreases
