1. How many milliliters of 0.250 M HCl needs to react with excess Zn to produce 0.0375 mol H2? 2. How many milliliters of 0.250 M HCl needs to react with excess Zn to produce 2.5 g ZnCl2?

3. If excess Zn is added to 450 mL of 0.250 M HCl, what mass of ZnCl2 can be produced?

Ithe undersigned only for use your own email and delete any and copies and of the itself and to be there is a good timewhat does a decrease in temperature indicate about the molecules in a sample of liquid water? decreased chemical energy of the moleculesdecreased kinetic energy of the moleculesincreased chemical energy of the moleculesincreased kinetic energy of the moleculeshow does a sample of helium at 15 â°c compare to a sample of helium at 215 k? the helium at 15 â°c has a higher average kinetic energy than the sample at 215 k.the helium at 15 â°c has lower nuclear energy than the sample at 215 k.the helium at 15 â°c has slower-moving atoms than the sample at 215 k.the helium at 15 â°c has smaller atoms than the sample at 215 k.

Ibelieve it is b. proton.hope my answer has you : )

Oxygen= 88ghydrogen= 12g

Answer/// he concludes that the atom particles can be broken due to the paddle wheel being moved by particles coming out of the metal;
