For the following reaction, 4.51 grams of water are mixed with excess silicon tetrafluoride. The reaction yields 8.32 grams of hydrofluoric acid. silicon tetrafluoride (s) water (l) hydrofluoric acid (aq) silicon dioxide (s) What is the theoretical yield of hydrofluoric acid

8 m/s because for him to get the same amount of energy as ray is putting out, bobby, who weighs half as much as ray, needs to run twice as fast.

idk what the question is about

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.
