5000 cm³ (5L) of Cu(NO₃)₂ contain 10 moles
∴ 1000 cm³ of Cu(NO₃)₂ contain x moles
x = (1000 cm³ × 10 moles) ÷ 5000 cm³
∴ the concentration of the solution is2 mol/dm³ or 2 mol / L
Answer:hydrates
Explanation:Hydrate, any compound containing water in the form of H2O molecules
Answer:
Rutherford predicted that an atom has a dense core called a <u>nucleus</u>.
Explanation:
Ernest Rutherford was a physicist who is known as the father of nuclear physics. He suggested an atomic model known as the Rutherford model. According to him, the atom consists of a tiny, dense, positively charged core called a nucleus and negatively charged particles called electrons that circulate around it The nucleus consists of positively charged particles called protons and neutral particles called neutrons.

Answer:
![H_2CO_3\rightleftharpoons H_2O + CO_2](https://tex.z-dn.net/?f=H_2CO_3%5Crightleftharpoons%20H_2O%20%2B%20CO_2)
Explanation:
When carbon dioxide dissolves and reacts with water, the water and the gaseous
reacts to form a dilute mixture solution of
(carbonic acid ).
The reaction is ![H_2O + CO_2\rightleftharpoons H_2CO_3](https://tex.z-dn.net/?f=H_2O%20%2B%20CO_2%5Crightleftharpoons%20H_2CO_3)
This is a forward reaction. And the symbol
shows that the reaction can be reversible. It means that the reaction can be carried in forward direction as well as in the backward direction.
The reaction attains chemical equilibrium until the reactants and the products no longer changes with time.
The carbonic acid can also dissociates into carbon dioxide and water in the backward direction.
![H_2CO_3\rightleftharpoons H_2O + CO_2](https://tex.z-dn.net/?f=H_2CO_3%5Crightleftharpoons%20H_2O%20%2B%20CO_2)
