Explanation:
Rats and mice are both rodents, so look similar - the biggest difference is their size. Rats are larger and heavier while mice have smaller slender bodies. Mice also have long slender tails (for their body size) covered in hair compared to rat tails which are shorter, thicker and hairless
<span>Use the Ideal law Equation :
P.V= n.R.T
V = 0.5 L
P = 1.0 atm
</span><span>R= 0.0821 L*atm/mol*K
</span>
<span>n = R*T/P*V
</span><span>P*V= n*R*T
</span>
1.0 * 0.5 = n *<span>0.0821*298
0,5 = n* 24.4658
n = 0,5 / 24.4658
n =0.0204 moles

There are actually three: One oxygen atom and two hydrogen atoms.
Answer:
Net ionic equation: 2I⁻(aq) + Cr²⁺(aq) → CrI₂(s)
<h3>
Explanation:</h3>
- A chemical equation shows chemical symbols of compounds known as reactants and compounds known as products in a chemical reaction.
- The chemical equation between hydroiodic acid and chromium (II) carbonate is given by;
2HI(aq) + CrCO₃(aq) → H₂CO₃(aq) + CrI₂(s)
- The Ionic equation is an equation that shows all the ions involved in a chemical reaction.
- In this case, the ionic equation is;
2H⁺ I⁻(aq)+ Cr²⁺ CO₃²⁻(aq) → 2H⁺ CO₃²⁻(aq) + CrI₂(s)
- The net ionic equation is an equation showing only the ions that take part in the reactions. The ions that do not take part in the chemical reaction known as spectator ions are not shown when writing net ionic equations.
- Spectator ions are those ions that do not change state after the chemical reaction has taken place. In this case, hydrogen ions and carbonate ions are spectator ions.
- The net ionic equation is
2I⁻(aq) + Cr²⁺(aq) → CrI₂(s)
