Answer:
2 C6H6 + 15 O2 ( 12 CO2 + 6 H2O
Explanation:
Just choice D.
If you find the number of atoms of each element, you will find that only choice D has the same amounts on each side of the equation.
Answer :
the amount of heat,in joules, required to increase the temperature of a 49.5-gram sample of wanted from 22°c to 66°c is 9.104 Joules.
Explanation:
The answer can be calculated using the formula
Q = mCрΔT
where
Q is the amount of heat required in joules to raise the temperature.
m is the mass of the sample in Kg.
Cp is the specific heat of the sample in J/Kg°C.
ΔT is the change in temperature required.
Here, m = 49.5-gram = 0.0495 kg
Cp = 4.18 J/Kg°C (for water)
T₁ = 22°C ; T₂ = 66°C
ΔT = 66 - 22 = 44
Substituting values in Q = mCрΔT
Q = (0.0495)(4.18)(44)
Q = 9.104 J
2NH3 + H2O2 → N2H4 + 2H2O
The atomic radius increases as you go down a group.
