Specialized cells in the stomach release HCl to aid digestion. If they release too much, the excess can be neutralized with a base in the form of an antacid. Magnesium hydroxide is a common active ingredient in antacids. As a chemist testing commercial antacids, you use 0.10 M HCl to simulate the acid concentration in the stomach. How many millilitres of this "stomach acid" will react with a tablet containing 0.10 g of magnesium hydroxide?

answer seismograph;

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
