54 points the solubility of sodium chloride is 35.9 g/100 g h2o at 20°c. 35.9 g of sodium chloride are added to 100 g of water, and all of it dissolves. another solution is made from the same amount of salt and the same amount of water. this time some solid remains undissolved. what factor could cause the difference? volume temperature beaker size solute purity

How many moles of al3+ ions are in 1.25 moles of al2o3

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)

How many moles are in 43.9 l of oxygen
