HELP ME PLEASE PLEASE PLEASE i need to show my work too!!
In the following synthesis of water reaction:

2 H2(g) + O2 (g) --> 2H2O (l)

If you start the reaction with 150.0 L of oxygen and 150.0 L of hydrogen,

a.) Do stoichiometry to identify the limiting reactant

b.) Do stoichiometry to identify the excess reactant?

c.) How many grams of water can be produced?

d.) Calculate the percent yield if you actually produce 111.5 grams of water while performing this reaction in the lab.

Consider three unlabeled bottles, each contain small pieces of one of the following metals. - magnesium - sodium - silver the following reagents are used for identifying the metals. - pure water - a solution of 1.0 molar hcl - a solution of concentrated hno3 (a) which metal can be easily identified because it is much softer than the other two? describe a chemical test that distinguishes this metal from the other two, using only one of the reagents above. write a balanced chemical equation for the reaction that occurs. (b) one of the other two metals reacts readily with the hcl solution. identify the metal and write the balanced chemical equation for the reaction that occurs when this metal is added to the hcl solution. use the table of standard reduction potentials (attached) to account for the fact that this metal reacts with hcl while the other does not. (c) the one remaining metal reacts with the concentrated hno3 solution. write a balanced chemical equation for the reaction that occurs. (d) the solution obtained in (c) is diluted and a few drops of 1 m hcl is added. describe what would be observed. write a balanced chemical equation for the reaction that occurs.

Areaction is first order with respect to reactant x and second order with respect to reactant y. which statement describes the rate law for this reaction?
