Consider the following metal-acid reaction below: 2 HCl + Mg --> MgCl2 + H2

If 1.5 g of Mg are dissolved in excess HCl, and all of the produced H2 gas is collected inside of a 1.2-L sealed flask at 23 C, then calculate the pressure of this produced H2 gas.

Water is initially present in a state where its molecules are far apart. during a change of state, its molecules slow down. which change of state has most likely taken place? from a gas to a liquid from a liquid to a gas from a solid to a liquid from a gas to a plasma
