Answer:
A) wrong. The molar is same so A is hevier
B)
Explanation:
Xg/mol × (same molar)= g
→ bigger molar bigger mass
The new volume if the balloon is cooled at constant pressure is 3.98 L.
Charles's law, states that the volume occupied by a fixed amount of gas is directly proportional to its absolute temperature if the pressure remains constant.
The new volume is calculated using the Charles law formula
V₁ / T₁ = V₂ / T₂
where,
V₁ = The initial volume of air = 4.24 l
T₁ = 23.00 °C into kelvin = 23 +273 =296 K
T₂ = 5.00 °C into kelvin = 5.00 + 273 = 278 K
V₂ = ?
By making V₂ subject the subject of the formula by multiplying both sides by T₂
V₂ = ( V₁ × T₂ ) / T₁
V₂ = (4.24 L × 278 K) / 296 k
= 3.98 L
Therefore, the new volume, if the balloon is cooled at constant pressure, is 3.98 L.
An air-filled balloon will contract when chilled and expand when heated. This occurs because the gas that makes up the air within the balloon expands when it is warm and contracts when it is cool.

Answer:
The mass % of the solution is 10.51%.
Explanation:
Mass of solute i.e. RbI = 96.4 g
Volume of the solution = 865 mL
Mass of the solution = m
Density of the solution = d = 1.06 g/mL
The mass % of the solution:
Answer:
Molecules of matter such as liquid, gas and solid still move even if the energy is transferred because it isn't a hundred percent. There is still energy and the time it took to transfer that said energy would have changed its state of matter.
Explanation:
Solid -the molecules are tight together. (touching)
Liquid - the molecules are close but not touching about mid way(not to far not to close)
Gas- the molecules in gasses are far apart.
It almost always goes from solid to liquid to gas. but in extreme conditions it could be different.
