When dissolved in water, a strong acid

A. ionizes completely.

B. releases hydrogen gas.

C. produces an alkaline solution.

D. produces a solution that does not conduct electric current.

A strong acid IONIZES COMPLETELY when dissolved in water.

Explanation:

An acid is said to be a strong acid when on dissolving in water is completely ionized into its proton and conjugate base.

The strength of an acid is determined by the ease in which an acid releases it's proton. Strong acids produces weak conjugate bases and are useful in accelerating some certain chemical reactions and causes chemical burns when exposed to it.

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer
