Answer: 47.04 L will be the volume occupied by the 2.1 moles of nitrogen gas at STP.
Explanation:
At STP,
1 mol of ideal gas occupies = 22.4 L
Considering nitrogen gas to be an ideal gas
Then 2.1 moles of the nitrogen gas will occupy:
47.04 L will be the volume occupied by the 2.1 moles of nitrogen gas at STP.
PH + pOH = 14
pH = 14 - pOH = 14 - 2 = 12
A pOH of 2 is equivalent to a pH of 12. A pH greater than 7 is basic, and 12 is greater than 7. Therefore, a solution with a pOH of 2 is basic.
Thus, the correct answer choice is B.
Answer:
(a) calculated density= 0.86 g/mL. The substance is probably toluene, density= 0.866 g/mL (b) 40.4 mL ethylene glycol (c) 1.11 x 10^3 g nickel
Explanation:
0.05 * V1 = 250 * 10
<span> V1 = 2500 / 0.05 </span>
<span> V1 = 2500 * 20 </span>
<span> V1 = 50000 mL </span>
<span>V1 = 50 Liters .
Hope this helped! :3</span>
