Barium carbonate (BaCO₃) <span>will be more soluble in acidic solution than in pure water, because Ksp (solubility constant) in water for this salt is very low.
In acid (for example hydrochloric acid) barium carbonate dissolves more because it forms weak electrolyte carbonic acid:
BaCO</span>₃(s) + 2HCl(aq) → BaCl₂(aq) + H₂CO₃(aq).
The molar mass of the hydrate is 278.06
The molar mass of the anhydrous salt is 151.92
The molar mass of water in the hydrate is 126.14
Answer:
c. stays the same, changes
Explanation:
temperature and heat go hand in hand, however while the change of state occurs, the temperature remains the same while the heat increases since the heat input is constant.
In science, physical quantities like length, weights etc are measured in units of metric or International System of units.
Some importance units are as follows:
1. Meter (m) for length.
2. Liter (L) for volume.
3. Gram (g) and kilogram (kg) for mass.
4. Degree Celsius (oC) for temperature.
5. Second for (s) time.
Given that the length of an object = 45.2 cm
SI unit of length is m
100 cm = 1.0 m
Therefore
45.2 cm * 1 .0 m/100 cm
= 0.452 m
