Answer:
The assumption is quite reasonable.........
A lightbulb contains Ar gas at a temperature of 295K and at a pressure of 75kPa. The light bulb is switched on, and after 30 minutes its temperature is 418 K. What is a numerical setup for calculating the pressure of the gas inside the light bulb at 418K?
Explanation:

sorry there are A LOT OF CHOICES soo..idont know for sure which one is the answer
but...
hope it helps
Answer:
D.) NaOH
Explanation:
Sodium always forms the cation, Na⁺.
Hydroxide is always written as OH⁻.
The compound should have an overall charge of 0 (be neutral). As you can see, the charges perfectly balance out (+1 + (-1) = 0). Therefore, there only needs to be one atom of each ion. The ionic compound is thus NaOH.
