A sample of 11.0 g of sodium is reacted with 18.6 g of water to produce sodium hydroxide and hydrogen gas. Using the balanced equation below, predict which is the limiting reactant and the maximum amount in moles of hydrogen gas that can be produced. 2Na+ 2H2O + 2NaOH + H2

Each of the following reactions is allowed to come to equilibrium and then the volume is changed as indicated. predict the effect (shift right, shift left, or no effect) of the indicated volume change. drag the appropriate items to their respective bins. co(g) + h2o(g) < => co2(g) + h2(g) (volume is decreased) pcl3(g) + cl2(g) < => pcl5(g) (volume is increased) caco3(s)< => cao(s) + co2(g) (volume is increased)

Describe the forces both attractive and repulsive that occur as two atoms move closer together.

Once similarity and one difference between a mixture of elements and a mixture of compounds
