Answer:
11 is the coefficient for C to balance the equation
Explanation:
C₁₂H₂₂O₁₁(s) + H₂SO₄(aq) + 1/2 O₂(g) → 11C(s) + CO₂(g) + 12H₂O(g) + SO₂(g)
12 Carbons in left side → 12 Carbons in right side
12 in sucrose → 11 in solid C + 1 in the CO₂
24 Hydrogens in left side → 24 Hydrogens in right side
22 in sucrose + 2 in sulfuric → 24 in water vapor
1 S in left side → 1 S in right side
1 S in sulfuric → 1 S in sulfur dioxide
16 O in left side → 16 O in right side
11 O in sucrose + 4 in sulfuric + 1 O at ground state → 2 O in carbon dioxide + 12 in water vapor + 2 in sulfur dioxide
Answer:
P₂ = 2 atm
Explanation:
Given data:
Initial volume = 10.0 L
Initial pressure = 4.0 atm
Final volume = 20.0 L
Final pressure = ?
Solution:
The given problem will be solved through the Boly's law,
"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"
Mathematical expression:
P₁V₁ = P₂V₂
P₁ = Initial pressure
V₁ = initial volume
P₂ = final pressure
V₂ = final volume
Now we will put the values in formula,
P₁V₁ = P₂V₂
4.0 atm × 10.0 L = P₂ × 20.0 L
P₂ = 40.0 atm. L/ 20.0 L
P₂ = 2 atm

For question 2: N2O
Answer:
Over time the metal will cool and the water will heat up. Eventually the two objects will have the sametemperature. They are then said to be in thermal equilibrium with one another.
