Answer:
C + 2H2 ⇒ CH4
Explanation:
In order to balance a chemical equation you need to make sure that the number of atoms on both sides are equal
C + H2 = CH4
C = 1
H = 2
Products:
C = 1
H = 4
H2 = 2 × 2 = 4
C + 2H2 ⇒ CH4
Hope this helps.
They make science a thing. Science isn't just space and microbes etc. We need science to solve things in society, politics, and economics.
Answer is: <span>the pressure is 1.12 atm.
</span>n(O₂) = 0.00825 mol, amount of substance.
V = 174 mL ÷ 1000 mL/L = 0.174 L, volume of gas.
<span>
T = 15°C = 288.15 K; temperature.
R = 0.08206 L·atm/mol·K, </span>universal gas constant.<span>
Ideal gas law: p·V = n·R·T.
</span>p =
n·R·T / V.
p = 0.00825<span> mol · 0.08206 L·atm/mol·K · 288.15 K /
0.174 L.
p = 1.12 atm.</span>
