Answer:
I believe the answer would be: D
an independent variable that is affected by the other
experimental variable
Correct me if im wrong
Explanation:
i know don't know the answerrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr rrrrrrrrrrrrrrrrrrrrr but just guessing is d. sodium
<span>60. 4Li(s) + O2(g) >>>>>>>>>>> 2Li2O(s)
moles O2 required = (84 grams Li) * (1 mol Li / 6.941 grams Li) * (1 mol O2 / 4 mol Li) = 3.026 moles O2 required.
PV = nRT, P = 1 atm, V = ?, n = 3.026 moles, R = 0.0821 L*atm/mol*K, T = 273 K
(1 atm)*(V) = (3.026 moles O2) * (0.0821 L*atm/mol*K) * (273 K)
V = 67.82 Liters is the answer.
hope this helps</span>
Answer:
99 L
Explanation:
Step 1: Given data
Moles of nitrogen: 4.4 moles
Step 2: Calculate the volume occupied by 4.4 moles of nitrogen
The volume occupied by a gas depends on other conditions such as pressure (P) and temperature (T). If we have this information, we can calculate the volume of the gas using the ideal gas condition.
P × V = n × R × T
Since the task doesn't inform the conditions, we can assume it is under standard pressure (1 atm) and temperature (273.15 K). At STP, 1 mole of any gas occupies 22.4 L.
4.4 mol × 22.4 L/1 mol = 99 L
