The missing labels are:
- CuCO₃(s), H₂SO₄(aq): reactants.
- +: plus sign.
- CuSO₄(aq), H₂O(l), CO₂(g): products.
- (s): solid.
- (aq): aqueous.
- (l): liquid.
- (g): gaseous.
<h3>What is a chemical equation?</h3>
It is a way to represent a chemical reaction.
Let's consider the following chemical equation.
CuCO₃(s) + H₂SO₄(aq) → CuSO₄(aq) + H₂O(l) + CO₂(g)
The missing labels are:
- CuCO₃(s), H₂SO₄(aq): reactants. They are on the left side of the equation.
- +: plus sign. It separates substances.
- CuSO₄(aq), H₂O(l), CO₂(g): products. They are on the right side of the equation.
- (s): solid.
- (aq): aqueous.
- (l): liquid.
- (g): gaseous.

Explanation:
this type of problem needs convertion method we need to convert from grams to pound.
Answer:
185.2 g/mol.
Explanation:
Solvent = Benzene
Solute = lauryl alcohol
Given:
Mass of solute = 5 g
Mass of solvent = 0.1 kg
Freezing point of solvent, Temp.f = 4.1 °C
Initial freezing point of solvent, Temp.i = 5.5 °C
Molal freezing depression constant for Benzene, kf = 5.12 °C/m
ΔTemp.f = Temp.f - Temp.i
= 5.5 - 4.1
= 1.4 °C
ΔTemp.f = kf * m
Where m = molality
m = 1.4/5.12
= 0.27 mol/kg
Molality = number of moles of solute/mass of solvent
Number of moles = 0.27/0.1
= 0.027 mol.
Molar mass = mass/number of moles
= 5/0.027
= 185.2 g/mol.
Answer:
1. Polar
2. Non-polar
3. Non-polar
4. Polar
5. Non-polar
6. Polar
Explanation:
Polar bonds are formed between molecules that share electrons unequally/unevenly. In a polar molecule, one atom is more electronegative than the other i.e it attracts/pulls more electrons than the other atom, hence, it ends up leaving the other atom with a positive charge i.e fewer electrons around its atom. Also, every molecule that has a symmetrical arrangement is NON-POLAR while the opposite is POLAR.
Based on this, the answers to the asked questions are in BOLD.
1. A POLAR bond is one where there are more shared electrons grouped around one atom than the other.
2. A NON-POLAR bond is one where the electrons are evenly distributed between the two atoms sharing electrons.
3. A molecule with symmetry is NON-POLAR
4. A molecule that does not have symmetry is POLAR.
5. A NON-POLAR molecule has its valence electrons evenly distributed around the molecule.
6. A POLAR molecule has one of its sides with more or fewer electrons than the other sides.
