Zn(s) + 2HCl(aq) → ZnCl2(aq) + H2(g)
When combining zinc metal with hydrochloric acid, you notice that you run out of zinc and still have plenty of hydrochloric acid to
continue the reaction. What is the term used to describe the zinc?

Nonmetals usually react by gaining electrons

Firstly, the water in the dams hold gravitational potential energy as they are above ground level. the gravitational potential energy is then transferred to kinetic energy as it falls, spinning the turbinethe turbine then spins the generator, which is a large magnet surrounded by metal coils. by doing this, the generator generates electricity. in this action, the energy transfer taken place is kinetic to electric energy

☆ionisation energy increases across a period from na -> ar☆ionisation energy decreases down a group from li -> fr☆ionic radius decreases across a period from na -> cl☆ionic radius increases down a groupfrom f -> ii hope it clarifies your doubts
