Makovka662 [10]

Answer:

45.3°C

Explanation:

Heat gained = mass × specific heat × increase in temperature

q = mC (T − T₀)

Given C = 0.128 J/g/°C, m = 94.0 g, q = 305 J, and T₀ = 20.0°C:

305 J = (94.0 g) (0.128 J/g/°C) (T − 20.0°C)

T = 45.3°C

aalyn [17]

Answer:

The answer is "82.2 torr"

Explanation:

moles of Xe:

= \frac{0.06}{131.293} \\\\ =0.00045699313 \ \mol

moles of F_2:

= \frac{0.0274}{38} \\\\= 0.00072105263\ \  mol

moles of produced XeF_2:

= 0.00024

moles of left Xe:

= 0.00021

Calculate the Pressure:

= \frac{(0.08206\times 0.00024 \times 293)}{(.1)}   + \frac{(0.08206\times  0.00021 \times  293)}{(.1)} \\\\= 0.10819611 \ \ atm \\\\ = 0.10819611 \times  760 \\\\ = 82.2 \ \ torr
