Students in a chemistry class added 5g of zinc (Zn) to 50g of hydrochloric acid (HCl). A chemical reaction occurred that produced zinc chloride (ZnCl2) and 6g of hydrogen gas (H2). Zn + ___HCl à ZnCl2 + H2

A.
49g

B.
55g

C.
61g

D.
Not enough information to determine the mass of the zinc chloride.

In an effort to address concerns about global warming, a power plant in portland, oregon is designed to take all of its exhaust gases from its boilers and recycle the co2 using the solvay process to make sodium hydrogen carbonate. the reaction is shown below. nh3(g) + h2o(l) + co2(g) + nacl(aq) → nahco3(aq) + nh4cl(aq) how many liters each of nh3 and co2 (both at stp) would be consumed to produce 3.00 kg of sodium bicarbonate? the volume of both nh3 and co2 would be

If you burn 46.6 g of hydrogen and produce 416 g of water, how much oxygen reacted
