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.

pyrite is a mineral composed of 46.5 mass % iron and 53.5 mass % sulfur. determine the empirical formula for calcocite.
padilas [110]

The empirical formula for pyrite is FeS2.

HOW TO CALCULATE EMPIRICAL FORMULA:

  • The empirical formula represents the simplest whole number ratio of constituents element of a compound. The empirical formula of pyrite can be calculated as follows:

46.5 mass % Fe = 46.5g of Fe

53.5 mass % S = 53.5g of S

  • Next, we divide each element's mass value by its molar mass

Fe = 46.5g ÷ 56g/mol = 0.83mol

S = 53.5g ÷ 32g/mol = 1.67mol

  • Next, we divide each mole value by the smallest (0.83mol)

Fe = 0.83mol ÷ 0.83 = 1

S = 1.67mol ÷ 0.83 = 2.014

Approximately, the ratio of Fe to S is 1:2. Therefore, the empirical formula of pyrite is FeS2.

How many Ne atoms are contained in 32.0 g of the element?
Svetlanka [38]
Mass atomic of Ne=20.18 u
Therefore:
molar mass=20.18 g/1 mol

1 mole=6.022*10²³ particles (atoms or molecules)

Then: 6.022*10²³ atoms are contained in 20.18g

Now, We can solve this problem by the three rule.

6.022*10²³ atoms-------------------20.18 g
x------------------------------------------32 g

x=(6.022*10²³ atoms * 32 g)/20.18 g=9.55*10²³ atoms.

Answer: 9.55*10²³ Ne atoms are contained in 32 g of the element.
