2 answers:
Answer: C. When substances are chemically combined, the properties of the new substances that are formed are often different from the properties of the original substances
Explanation: In chemical reactions, the substances combine and undergo rearrangement to form new substances and the new substances formed have different properties than the combing substances.
In the given chemical reaction, Na in solid state and a reactive metal combines with gaseous and poisonous chlorine but in stable form to give sodium chloride which is salt and is non toxic.

Answer:
The temperature at which the liquid vapor pressure will be 0.2 atm = 167.22 °C
Explanation:
Here we make use of the Clausius-Clapeyron equation;
Where:
P₁ = 1 atm =The substance vapor pressure at temperature T₁ = 282°C = 555.15 K
P₂ = 0.2 atm = The substance vapor pressure at temperature T₂
= The heat of vaporization = 28.5 kJ/mol
R = The universal gas constant = 8.314 J/K·mol
Plugging in the above values in the Clausius-Clapeyron equation, we have;
T₂ = 440.37 K
To convert to Celsius degree temperature, we subtract 273.15 as follows
T₂ in °C = 440.37 - 273.15 = 167.22 °C
Therefore, the temperature at which the liquid vapor pressure will be 0.2 atm = 167.22 °C.
