Look at the reaction below.

which substance is the acid in the reaction?
mg(s)
h2(g)
mgso4(aq)
h2so4(aq)

H2SO4

Explanation:

H2SO4 is actually one of the strongest acids, coming to a pH value very close to 1. Acids transfer their hydrogen ions to other substances, such as water, and usually have hydrogen in their formula. In this case, H2SO4 has hydrogen in its formula and is the acid in this case.

Explanation:

An acid is defined as the acid which completely dissociates when dissolved in water and release ions in their aqueous states.

A base is defined as the base which completely dissociates when dissolved in water and releases ions in their aqueous states.

is an element, is a compound, is a salt formed by combination of acid and base.

The equation for the dissociation of sulphuric acid is given by:

i think it is d. e because the next one is igneous.

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.
