Answer:
The chemical equation by putting, a 2 on C₅H₁₂O, 15 on O₂, 10 on CO₂ , and 12 on H₂O in the equation;
2C₅H₁₂O + 15O₂ → 10CO₂ + 12H₂O
Explanation:
- Chemical equations are balanced by putting coefficients on the reactants and products to ensure the total number of atoms on the left side equal to those on the right side.
- Balancing chemical equations is done to make chemical equations obey the law of conservation of mass.
- According to the law of conservation of mass, the mass of the reactants should always be equal to the mass of products.
- This is done by balancing chemical equations to ensure the total number of atoms on the left side is equal to that on the right side.
- Therefore, the balanced equation is;
2C₅H₁₂O + 15O₂ → 10CO₂ + 12H₂O
0.500 moles is roughly .5*6.022*10^23=3.011*10^23 atoms. This is independent of STP.

Answer:
353kg
Explanation:
2000 x 0.1765 = 353kg
for every 1 cubic metre of helium there is 0.1765 kg of it
the balloon is holding 2,000 cubic metres of the helium.
That means that there are 2000 times of 0.1765kg of helium in the balloon
so you times 0.1765kg by 2000
