It really base on facts ,hypotheses,evidences,concepts,
The final gas pressure : 175.53 atm
<h3>Further explanation</h3>
Maybe the complete question is like this :
A ridged steel tank filled with 62.7 l of nitrogen gas at 85.0 atm and 19 °C is heated to 330 °C while the volume remains constant. what is the final gas pressure?
The volume remains constant⇒Gay Lussac's Law
<em>When the volume is not changed, the gas pressure in the tube is proportional to its absolute temperature </em>

P₁=85 atm
T₁=19+273=292 K
T₂=330+273=603 K

Answer:
gold and platinum
Explanation:
Very unreactive metals, such as gold and platinum, are found in the Earth's crust as pure metals. These are called native metals.

The reaction is balanced
The equilibrium constant is defined as the concentration ratio of the products and reactants. They are not considered pure solids and liquids.

So the answer is option B.
