You have a glass of liquid and combine it with a mysterious solid and notice that over time the color changes. this questions ha

1. This can be due to the dissolving of the solid in liquid and form a solution.

Dissolving is a physical property because dissolving doesn't form new substances and the chemical composition of the solid is not changed.

The color building up over the time can be due to the rate of dissolving of the solid and amount of particles have been dissolved.

Example:

  • Dissolving of CuSO₄ solid in water.
  • This develops a blue color.

2. This can be due to the chemical reaction between the solid and liquid.

Chemical reaction is a chemical property because from reacting substances new substances can be formed which the chemical formula is different from initial substances.

The color building up over the time can be due to the rate of the reaction and the amount of reactants.

Example:

  • The reaction between calcium metal with water.
  • The color of Ca(OH)₂ is white color.
  • Reaction is

       Ca(s) + 2H₂O(l) → Ca(OH)₂(aq) + H₂(g)

8. A 220 mL sample of helium gas is in a cylinder with a movable piston at 105 kPa and 275K. The piston
Harrizon [31]

The sample has a new pressure of 274kPa. If at 105 kPa and 275K, a 220 mL sample of helium gas is contained in a cylinder with a moving piston. The sample is pushed till it has a 95.0 mL volume and 310K .

The macroscopic characteristics of ideal gases are related by the ideal gas law (PV = nRT). A gas is considered to be perfect if its particles (a) do not interact with one another and (b) occupy no space (have no volume). Where P= pressure  V= volume and T = temperature.

From ideal gas equation

P₁V₁/T₁ =P₂V₂/T₂

105×220÷275 = P₂ ×95÷310

P₂= (105×220×310)÷(275×95)

P2= 7161000/26125

P2 = 274.105 kPa

Hence, the new pressure of helium gas is 274kPa

Allushta [10]

Answer: The substance is neutral

Explanation:

If you place red litmus paper into a basic substance, it turn's blue. When it comes in contact with an acidic or neutral substance, it doesn't change colour it remains red.

Blue litmus paper in acid turns red when placed in a basic or neutral solution it remains blue. From this it can be concluded that the solution is neutral.
