Explanation:
Each atom type contains the same number of protons. Chemical bonds link elements together to form more complex molecules called compounds. A compound consists of two or more types of elements held together by covalent or ionic bonds
Answer:
The three definitions are listed in the explanation.
Explanation:
A nonelectrolyte is a molecular compound that does not consist of ions hence it does not dissociate into ions in solution.
A weak electrolyte is a soluble ionic compound that dissociates only to very small extent into ions in solution.
A strong electrolyte is a soluble ionic compound that dissociates completely into ions when dissolved in water.
The answer is it breaks down food into energy
Have a Nice day
Answer is: volume is 25.08 liters.
Balanced chemical reaction: 2Na + 2H₂O → 2NaOH + H₂(g).
m(Na) = 51.5 g; mass of sodium.
n(Na) = m(Na) ÷ M(Na).
n(Na) = 51.5 g ÷ 23 g/mol.
n(Na) = 2.24 mol; amount of sodium.
From chemical reaction: n(Na) : n(H₂) = 2 : 1.
n(H₂) = 2.24 mol ÷ 2.
m(H₂) = 1.12 mol; amount of hydrogen gas.
V(H₂) = n(H₂) · Vm.
V(H₂) = 1.12 mol · 22.4 L/mol.
V(H₂) = 25.08 L; volume of hydrogen gas.
Answer:
BaCo3 (s)
Explanation:
Because it is being formed from two aqueous solutions, and the (s) indicates that it is a solid. Precipitate means "formed into solid". Since BaCo3 is a product, is solid, is formed from two aqueous solutions, it is a precipitate.
