Answer:
Impossible to balance
Step-by-step explanation:
There is an infinite number of solutions, because the equation is a combination of two simpler ones.
One reaction forms C, and the other forms CO₂.
C₁₂H₂₂O₁₁ ⟶ 12 C + 11 H₂O
C₁₂H₂₂O₁₁ + 24H₂SO₄⟶ 12CO₂ + 35H₂O + 24SO₂
You can add the two equations in an infinite number of linear combinations, so there is no unique solution.
Answer:
Its pressure will be 0.54 atm at 100 K.
Explanation:
Gay-Lussac's law indicates that, as long as the volume of the container containing the gas is constant, as the temperature increases, the gas molecules move faster. Then the number of collisions with the walls increases, that is, the pressure increases. That is, the pressure of the gas is directly proportional to its temperature.
Gay-Lussac's law can be expressed mathematically as the quotient between pressure and temperature equal to a constant:
Studying two different states, an initial state 1 and a final state 2, it is satisfied:
In this case:
- P1= 1.75 atm
- T1= 50 °C= 323 K (being 0 C=273 K)
- P2= ?
- T2= 100 K
Replacing:
Solving:
P2= 0.54 atm
<u><em>Its pressure will be 0.54 atm at 100 K.</em></u>
<span>Answer:
The law of conservation of mass states that mass in an isolated system is neither created nor destroyed by chemical reactions or physical transformations. According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants.</span>
