Answer: B. combustion

Explanation: $2Al+3O_2\rightarrow 2Al_2O_3$

A. Single replacement: A single replacement reaction is one in which a more reactive element displaces a less reactive element from its salt solution.

B. Combustion: is a chemical reaction between a substance and an oxidant usually atmospheric oxygen accompanied by generation of heat and light.

C. Double replacement: A double replacement reaction is one in which exchange of ions take place.

D. Decomposition : is a reaction in which one reactant decomposes to give two or more than two products.

2. Reaction between magnesium & sulphur

diamong [38]

Answer:

Mg combines with SO2 to create MgO and S. When magnesium ribbon is burned in a sulphur dioxide-rich environment, the element magnesium reacts with the oxygen atom in the sulphur dioxide and burns constantly. This is a redox reaction (oxidation-reduction). Mg is a reducing agent, while SO2 is an oxidising agent.

How many molecules are in

diamong [38]

Answer:

3.6 × 10²⁴ molecules

Explanation:

Step 1: Given data

Moles of methane (n): 6.0 moles

Step 2: Calculate the number of molecules of methane in 6.0 moles of methane

In order to convert moles to molecules, we need a conversion factor. In this case, we will use Avogadro's number: there are 6.02 × 10²³ molecules of methane in 1 mole of molecules of methane.

6.0 mol × 6.02 × 10²³ molecules/1 mol = 3.6 × 10²⁴ molecules
