The amount of heat needed to cook the pork roast is 1700 kJ.
The amount of heat absorbed by the roast is 14% of the heat produced = 14% X ?H = 310.38 kJ/mol
One mole of propane burns to produce 3 moles of CO2 and -2217 kJ of heat.
1700kJ/ (14% X ?H) = mol of C3H8 burned
1700kJ / (310.38 kJ/mol) = 5.48 mol C3H8
Since 3 moles of CO2 are produced:
3 X 5.48 mol= 16.43 mols of CO2
convert moles to grams:
16.43 mol CO2 X 44.0g/mol ~ 722.9 g CO2 produced
Answer:
Solution given:
angle : 80°
hypotenuse:y=?
opposite=21
we have
Sin 80=
doing crisscrossed multiplication
we get
y=
<u>y=21.32</u>
Answer: x=-6
Step-by-step explanation:
Given
2x + 8 = -4
Subtract 8 on both sides
2x + 8 - 8 = -4 - 8
2x = -12
Divide 2 on both sides
2x / 2 = -12 / 2
x = -6
NOTE: I assume the questions "solve for c" actually means "solve for x"
Hope this helps!! :)
