Answer:
11.29 kJ (to 4 sf)
Explanation:
Here, ammonia is the limiting reactant.
For the reaction to occur once, 4 moles of ammonia must be consumed.
Thus means that the reaction can occur 0.1579/4=0.039475 times.
Therefore, (286)(0.039475) = 11.29 kJ (to 4 sf)
Answer:
Mole ratio of Carbon dioxide to Propane is;
3 : 1
Explanation:
The Balance Chemical Equation is as follow,
C₃H₈ + 5 O₂ → 3 CO₂ + 4 H₂O
According to equation, 1 mole of propane reacts with five moles of Oxygen gas to produce three moles of Carbon dioxide and four moles of Water. Therefore, the mole ratio of all reactants and products can be written as,
1 : 5 : 3 : 4
Where;
1 = C₃H₈
5 = O₂
3 = CO₂
4 = H₂O
Answer:
\large \boxed{\textbf{609 kJ}}
Explanation:
The formula for the heat absorbed is
q = mCΔT
Data:
m = 2.07 kg
T₁ = 23 °C
T₂ = 191 °C
C = 1.75 J·°C⁻¹g⁻¹
Calculations:
1. Convert kilograms to grams
2.07 kg = 2070 g
2. Calculate ΔT
ΔT = T₂ - T₁ = 191 - 23 = 168 °C
3. Calculate q
One of the most worrisome waste products of a nuclear reactor is plutonium 239 (239Pu). This nucleus is radioactive and decays by splitting into a helium-4 nucleus and a uranium-235 nucleus (4He +...
