what is a room status report - There is some heat released with each union of an H+ to a OH- to produce an H2O. The more unions you produce by increasing the concentration, the more heat is produced. So higher concentration . Mg and HCl forms a metal salt MgCl and produces Hydrogen gas. There may be a very slight increase in rate of reaction but this is permissible/ very negligible due to the fact that metals and acids form adducts and these can further react/ delay further reactions between the acid and metal molecules. Students follow the rate of reaction between magnesium and the acid, by measuring the amount of gas produced at 10 second intervals. 3 cm of magnesium ribbon typically has a mass of g and yields 40 cm 3 of hydrogen when reacted with excess acid. 50 cm 3 of 1M hydrochloric acid is a six-fold excess of acid. case study ziba design my kitchen
