Sveta_85 [38]

Answer:

Explanation:

Answer:

A. to determine the efficiency of the reaction

Explanation:

Percentage is the ratio of the actual yield to theoretical yield as a percentage. It is calculated by dividing the actual yield by theoretical yield then multiplying by 100%.

Calculation of percentage yield is important as it helps in the determination of efficiency of a reaction. For example in most industries for the purpose of making the most product with the least waste.

Additionally, calculating the percentage yield helps in determining other products that may be formed during the reactions.

Classify each of the following as a combination, decomposition, single replacement, double replacement, or combustion reaction:
hjlf

Answer:

1) single replacement

2) combustion reaction.

3) double replacement reaction

4) combination reaction

5) decomposition reaction

Explanation:

Chemical equation:

Fe₂CO₃ + 3C  →   2Fe + 3CO

The given reaction is single replacement reaction. In this reaction carbon react with Fe₂CO₃ and replace the iron from CO₃²⁻ and form free iron and carbon monoxide.

Chemical equation:

C₂H₄ + 3O₂   →  2CO₂ + 2H₂O

The given reaction is combustion reaction. In which ethene burn in the presence of oxygen form carbon dioxide and water.

Chemical equation:

Fe₂O₃ + 6HCl   →  2FeCl₃ + 3H₂O

The given reaction is double replacement reaction. In which anion and cation of both reactants exchange with each others.

Chemical equation:

2Al + 2Br₂ →  2AlBr₃

The given reaction is combination reaction in which aluminium and bromine combine to form aluminium bromide.

Chemical equation:

C₆H₁₂O₆   →    6C + 6H₂O

The given reaction is decomposition reaction in which glucose molecule decompose to give water and carbon.
