<h3>Explanation:</h3>

Step 1: Define

Identify variables

[Given] 6.7 L O₂

[Solve] g O₂

Step 2: Identify Conversions

[STP] 22.4 L = 1 mol

[PT] Molar Mass of O: 16.00 g/mol

[PT] Molar Mass of C: 12.01 g/mol

Molar Mass of CO₂: 12.01 + 2(16.00) = 44.01 g/mol

Step 3: Convert

[DA] Set up: $\displaystyle 6.7 \ L \ O_2(\frac{1 \ mol \ O_2}{22.4 \ L \ O_2})(\frac{44.01 \ g \ O_2}{1 \ mol \ O_2})$
[DA] Divide/Multiply [Cancel out units]: $\displaystyle 13.1637 \ g \ O_2$

Step 4: Check

Follow sig fig rules and round. We are given 2 sig figs.

13.1637 g CO₂ ≈ 13 g CO₂

Li(s)+n2(g)→li3n(s) express your answer as a balanced chemical equation. identify all of the phases in your answer.

elixir [45]

equation is balanced when the number of molecules are the equal in both reacting side and the product side.
Li(s) + n2(g) ---> Li3n(s)
From the equation above the reaction is not balanced since the molecules are not equal in both reacting side and the product side.

The reaction is balanced by adding 6 in front of Li and 2 infront of Li3n
that is
6Li(s) + n2(g)-----> 2Li3n(s)

Explanation:

As it is known that $SF_{6}$ molecule is a non-linear molecule. Therefore, its isochoric heat capacity will be as follows.
