Liquid oxygen can be used as an oxidizer in rocket fuel as one of two propellants needed.
The Equation given in statement is as follow,
<span> 2 C</span>₂H₂<span> + O</span>₂<span> → 4 CO</span>₂<span> + H</span>₂<span>O
According to equation,
Carbon atoms on reactant side are 4 in number, and that on product side are also 4 in number. SO, carbon atoms are balanced.
Hydrogen atoms on reactant side are 4, and on product side are 2. Means Hydrogen atoms are not balance. So, to balance them multiply H</span>₂O with 2. So,
2 C₂H₂ + O₂ → 4 CO₂ + 2 H₂O
Now, calculate number of Oxygen atoms on both sides. There are 2 Oxygen atoms on reactant side and 10 Oxygen atoms on product side. So, to balance them multiply O₂ on reactant side with 5. So,
2 C₂H₂ + 5 O₂ → 4 CO₂ + 2 H₂O
Above Equation is balanced.
true you have to consider that like thats true man im just tryna waste space
Answer:
691.7 mmHg is the resulting pressure
Explanation:
Tha Gay-Lussac's law states that the pressure of a gas is directly proportional to its absolute temperature under constant volume. The equation is:
P1T2 = P2T1
<em>Where P is pressure and T asbolute temperature of 1, initial state and 2, final state of the gas.</em>
<em />
Computing the values of the problem:
T1 = 273 + 25 = 298K
P1 = 755.0mmHg
T2 = 273 + 0 = 273K
P2 = ?
755.0mmHg*273K = P2*298K
<h3>691.7 mmHg is the resulting pressure</h3>
Answer:
The answer is 4.
