The answer to question is B have a nice day
The salt is sodium chloride. It is an ionic bond.It dissolved well in the water because H20 is polar. the positive sodium ions are attracted to partially negative oxygen in the H20. While the sugar is sucrose, which made up of carbons and hydrogens. Where as the carbons and hydrogens are about equally electronegative,it is a nonpolar covalent bond, which means the charge of an atoms within the molecule are negligible.
Density of boat =
=
= 0.88 g / cm³
Since the density of water is greater than the density of the boat ( 1 > 0.88) then that means,
the boat will NOT sink.B.

Answer:
The answer to your question is below
Explanation:
Data
Aqueous sodium carbonate = Na₂CO₃ (aq)
Aqueous strontium chloride = SrCl₂ (aq)
Solid strontium carbonate = SrCO₃ (s)
Aqueous sodium chloride = NaCl (aq)
Unbalnced Chemical reaction
Na₂CO₃(aq) + SrCl₂(aq) ⇒ SrCO₃(s) + NaCl(aq)
Reactants Elements Products
2 Sodium 1
1 Carbon 1
1 Strontium 1
2 Chlorine 1
3 Oxygen 3
Balanced Chemical reaction
Na₂CO₃(aq) + SrCl₂(aq) ⇒ SrCO₃(s) + 2NaCl(aq)
Reactants Elements Products
2 Sodium 2
1 Carbon 1
1 Strontium 1
2 Chlorine 2
3 Oxygen 3
