The boiling point of the solution can be calculated by the equation of the colligative property named boilng point elevation.
The formula for the boiling point elevation is:
ΔTb = i * Kb * m
Where:
i = van't Hoof factor
Kb = molal boiling point constant
m = molality.
Solution:
1) i is 2 because the NaCl is ionice and dissociates into two ions.
2) Kb is given = 0.51 °C/m
3) m = moles of solute / kg of solvent
moles of solute is given = 3.8
kg of solvent = 185 g * 1 kg/1000g = 0.185 kg
m = 3.8 moles / 0.185 kg = 20.54 m
4) ΔTb = 2 * 0.51°C/m * 20.54m = 20.9 °C
5) The boiling point is the normal boiling point of water (100°C) plus the increase:
Tb = 100°C + 20.9°C = 120.9°C
Answer: 120.9°C.
True. If the balanced chemical equation did not account for all of the atoms in a reaction, the reaction could not be used for any type of quantitative analysis. It would also not be really useful since it is supposed to show how the molecules interact and in what quantities.

Explanation:
Answer:
Your stomach lining also secretes hydrochloric acid, which creates the ideal conditions for the protein-digesting enzymes to work. The potent hydrochloric acid kills bacteria, protecting your body from harmful microbes which can enter your body in food.
