The chemical reaction would be as follows:
CO + 2H2 =CH3OH
We are given the amount of reactants to be used. We have to use these amounts to determine which is the limiting reactant and how much of the excess reactant is left.
1.50x10^-6 g CO ( 1 mol / 28.01 g ) = 5.36x10^-8 mol CO
6.80 x10^-6 g H2 ( 1 mol / 2.02 g ) = 3.37x10^-6 mol H2
Therefore, it is CO that is consumed completely in the reaction and the number of moles gas left would be 3.37x10^-6 - 5.36x10^-8 = 3.32x10^-6 moles.
The answer is B. Lithosphere
Explanation: The upper layer of mantle is a zone of rigid brittle rock. Below the lithosphere is asphalt-like and is called the Asthenosphere.
Answer/Explanation:
No compounds must be made up of two or more elements. otherwise it wouldn't be a compound. There must be some type of combination or it isn't a compound.
