Consider the balanced reaction below:
CO + 3H2 + H2O + CH4
How many grams of methane,
CH4, are produced from the
complete reaction of 5.15 moles of
carbon monoxide, CO?

d.) the average kinetic energy of the gas particles is greater in container b because its particles move faster.

i think so it’s will be b yes i believe its

"you start with 15.67 g mgco3-xh2o, when heated and all the water is removed, you are left with 7.58 g mgco3 only.

therefore, you had 15.67 - 7.58 = 8.09g h2o  

moles of each :

7.58g mgco3 = ? moles = 7.58g / 83.4g/mole = 0.09moles  

8 09g h2o = ? moles = 8.09g / 18g/mole = 0.44moles  

molar ratio between the two by dividing both numbers by the smallest number :

0.09 / 0.09 = 1  

0.44 / 0.09 = 4.8  

mgco3-5h2o"
