scoundrel [369]

Answer: 1) only a salt and water

An acid and base reacts together to undergo neutralization to form salt and water.

HCl+NaOH\rightarrow NaCl+H_2O

where HCl is an acid and NaOH is a base to form salt (NaCl) and water (H_2O).

Answer: 2) The formula of the hydrogen ion is often written as H^+.

All acids dissociate in water to give  H^+ ions.

Answer: 3) Arrhenius acids are substances that ionizes to yield protons in aqueous solution.

HCl\rightarrow H^++Cl^-

Arrhenius bases are substance that ionizes to yield hydroxide ions in aqueous solution.

NaOH\rightarrow Na^++OH^-

Answer: 4) A conjugate acid base pair  transfers hydrogen ion.

CH_3COO^-+H_2O\rightarrow CH_3COOH+H_3O^+

Here CH_3COO^- accepts a proton and thus act as a base and the corresponding CH_3COOH is its conjugate acid.

Answer: 5) Bronsted Lowry acid is a substance that donates protons.  Bronsted Lowry base is a substance that accepts protons.

NH_4^+ and NH_3

NH_3+H^+\rightarrow NH_4^+

NH_3 is a acid which accepts proton and thus acts as base to form conjugate acid NH_4^+.

The definition of heat transfer through convection involves the movement of a fluid that causes heat to move away from a hear source. That being said, convection can take place in a lake, air inside, and air outside since both liquids and gasses are considered to be fluids. I hope this helps. Let me know if anything is unclear.
