Answer:
Where are the question's???
Explanation:
If nitrogen monoxide (NO) is added to 2SO2(g) + O2(g) → 2SO3(g),
it will react with O2 and decrease the reaction rate by lowering the amount of O2. So the answer is C. NO decreases collisions between the SO2 and O2 molecules.
Answer:
13.5 %
Explanation:
First we<u> calculate the mass of 500 mL of water</u>, using <em>its density</em>:
- 500 mL * 1.00 g/mL = 500 g
Then we <u>calculate the mass percent of potassium sulfate</u>, using the formula:
Mass of Potassium Sulfate / Total Mass * 100%
- 78 g / (78 + 500) g * 100 % = 13.5 %
The boiling point of HF is 19.54°C so it depends on the temperature of your room! Above this temperature it is a gas and below it, it is a liquid
