Answer
Explanation:
can you please put it in boxes so i can find out the answer
We first convert 1.32 atm to torr
1.32 atm = 1003.2 torr
Next, we apply Gay-Lussac's Law:
P₁/T₁ = P₂/ T₂
T₂ = (1003.2 x 34.6) / (760)
T₂ = 45.7 °C

Explanation:
Hello there!
In this case, since the percent by mass of a solute in a solution is computed via the following division:
Next, given the mass of HCl and that of water, we plug them in to obtain:
Best regards!
Answer:
The answer is D. 0.60 L
Explanation:
The balanced reaction equation including states of matter is;
H₂SO₄(aq) + 2NaOH(aq) → Na₂SO₄(aq) + 2H₂O(l)
More simple:
H2SO4 + 2NaOH → Na2SO4 + 2H2O
Now, we can see from this reaction equation that the mole ratio of NaOH to H2SO4 is 2:1
Number of moles of H2SO4 reacted = 1.2 moles
Hence;
2 moles of NaOH reacts with 1 mole of H2SO4
x moles of NaOH reacts with 1.2 moles of H2SO4
x = 2 * 1.2/1 = 2.4 moles of NaOH
Recall that;
Number of moles = Concentration * Volume
Volume = number of moles/concentration
Volume of NaOH is obtained from;
Volume = 2.4 moles/ 4.0 M
Volume = 0.60 L
