Tanzania [10]2 years ago
8 0

Answer:

2C₄H₁₀ + 13O₂ ⇒ 8CO₂ + 10H2₀

<h2>What is combustion? </h2>

The reaction of a substance with oxygen, producing one or more oxides, heat and light.

Butane (C₄H₁₀) is a hydrocarbon ( The name used for a hydrocarbon with four carbon atoms and only single bonds.) Butane consists of carbon and hydrogen and thus when it combust, it produces carbon dioxide and water.

2C₄H₁₀ + 13O₂ ⇒ 8CO₂ + 10H2₀

The following chemical equation follow the law of conservation of mass.

The law of conservation of mass states that in a closed system, mass is neither created nor destroyed during a chemical or physical reaction. The law of conservation of mass is applied whenever you balance a <u>chemical equation</u>. It is also applicable to stoichiometry. On the product side, the number of atoms must match the total of atoms on the product side. As a result, the equation must be balanced.

2.00 g of an unknown gas at STP fills a 500. mL flask. What is the molar mass of the gas?
otez555 [7]

Answer:

100g/mol

Explanation:

Given parameters:

Mass of unknown gas  = 2g

Volume of gas in flask  = 500mL  = 0.5dm³

Unknown:

Molar mass of gas = ?

Solution:

Since we know the gas is at STP;  

        1 mole of substance occupies 22.4dm³ of space at STP

    Therefore,

            0.5dm³ will have  0.02mole at STP

                     

Now;

   Number of moles  = \frac{mass}{molar mass}  

      Molar mass  = \frac{mass}{number of moles}   = \frac{2}{0.02}   = 100g/mol
