Question

Give the balance equation please !!!!!​

Answer 1

Answer:

Formula of propane is C3H8.

It is an hydrocarbon in the group of alkanes.

Combustion Equation:

$\boxed{\red{C_{3}H_{8} + 5O_{2} \rightarrow \: 3CO_{2} + 4H_{2}O \: + \Delta}}$

The best way to balance this Equation is by following the steps :

1. First balance the Carbon atoms on both sides

2. Correspondingly Hydrogen atoms should be checked and balanced.

3. Finally balance the oxygen atoms

Additional information:

1. Combustion of propane gives 2200 KiloJoules per mole of energy.

2. In that case , heat is released, so

∆H should be negative

3. In other words, we can say that 1 mole of propane reacts with 5 moles of oxygen to give 3 moles of carbon dioxide, 4 moles of water and energy

Answer 2

AnsWer:

•The formula of propane = C3H8

•When it burns in air it produces carbon dioxide and water with the release of energy.

•The skeletal chemical equation is:

$\sf{C_{3}H_{8}+O_{2}\longrightarrow\:CO_{2}+H_{2}O+energy}$

Now, balancing both sides by balancing no. of atoms:

$\leadsto{\sf{C_{3}H_{8}+5O_{2}\longrightarrow\:3CO_{2}+4H_{2}O}}$

Steps:

• First balancing Carbon atom by multiplying 3 on product side.

• Then balance Hydrogen by multiplying 4 on product side hydrogen.

• Lastly balance oxygen by multiplying 5 on reactant side.
