Answer: 20 g
Explanation: heat received Q = m c dT
Q= 50J , dT= 25 C anc c= 0.10 J / g C
And m = Q / c dT
CH4+2O2=> 2H2O+CO2
C- 1 on both sides
H- 4 on both sides
O - 4 on both sides
The Nuremberg War Crimes trials established the international legal precedent that individuals who violate human rights can be held responsible for their actions. The correct option in regards to all the options given in the question is option "2".

and the criminals were either hanged to death of were killed by the firing
squad.
Answer:
1.17 grams
Explanation:
Let's consider the balanced equation for the combustion of ethylene.
C₂H₄(g) + 3 O₂(g) → 2 CO₂(g) + 2 H₂O(l)
We can establish the following relations:
- 1411 kJ are released (-1411 kJ) when 1 mole of C₂H₄ burns.
- The molar mass of C₂H₄ is 28.05 g/mol.
The grams of C₂H₄ burned to give 59.0 kJ of heat (q = -59.0 kJ) is:
