Increases, boiling point, and vapor pressure are inversely proportional to each other.

think of this, water boils at a lower temperature at high altitude, like on the mountains because the atmospheric pressure there is lower.

Fluorine gas is placed in contact with calcium metal at high temperatures to produce calcium fluoride powder. What is the formul

yuradex [85]

The formula equation for any reaction is the chemical equation which involves the chemical formulas of the element(s) or compound(s) involved in the reaction. On the left side of the $\rightarrow$ , reactants are written and different reactants are separated by $+$ sign whereas on the right side of the $\rightarrow$ , products are written and different products are separated by $+$ sign. The phases (solid, liquid, or gas) of all the reactants and products are written in brackets after the chemical formula of respective reactants and products.

The formula for fluorine gas is $F_2 (g)$ , acts as reactant.

The formula for calcium metal is $Ca(s)$ , acts as reactant.

The formula for calcium fluoride is $CaF_2 (s)$ , acts as product.

The reaction is written as:

$F_2 (g)$ $+$ $Ca (s)$ $\rightarrow$ $CaF_2 (s)$

Hence, the formula equation for the reaction is:

$F_2 (g)$ $+$ $Ca (s)$ $\rightarrow$ $CaF_2 (s)$

A certain amount of gas is trapped in a nonrigid container at atmospheric pressure. If the container is cooled and the gas in th

GalinKa [24]

<h2>Answer:Volume of the container will decrease</h2>

Explanation:

Given that the gas is trapped,so the gas cant escape.

The number of moles of gas inside the container will remain constant.

The initial and final pressures are the same.
