Answer:

V = 56.816 cm³

Explanation:

Given that,

The measured value of the cylinder is 54.5 cm³

The percent error in the measurement of the volume is 4.25%

We need to find the actual volume of the cylinder.

Firstly, we can find the error in the calculation as follows :

E=54.5 \times \dfrac{4.25}{100}=\pm2.316

It is mentioned in the problem that, the teacher told her that she was 4.25% too high in her determination of the volume. It would mean that,

Total volume = 54.5 + 2.316 = 56.816 cm³

Hence, the actual volume of the cylinder is 56.816 cm³.

In a reaction, 25 grams of reactant
Vsevolod [243]

Answer:

D. 15g

Explanation:

The law of conservation of mass states that, in a chemical reaction, mass can neither be created nor destroyed. This means that the amount of matter in the elements of the reactants must be equal to the amount in the resulting products.

In this question, 25 grams of a reactant AB, was broken down in a reaction to produce 10 grams of products A and X grams of product B. According to the law of conservation of mass, the mass of the reactant must be equal to the total mass of the products. This means that 25 grams must also be the total mass of both products in this reaction. Hence, if product A is 10 grams, product B will be 25 grams - 10 grams = 15 grams.

Therefore, product B must be 15 grams in order to form a total of 25 grams when added to the mass of product A. This will equate the mass of the reactant AB and fulfill the law of conservation of mass.

When C2H5Cl(g) is burned in oxygen, chlorine gas is produced in addition to carbon dioxide and water vapor. 5145 kJ of heat are
Arisa [49]

<u>Answer:</u> The chemical equation is written below.

<u>Explanation:</u>

Combustion reaction is defined as the chemical reaction in which a hydrocarbon reacts with oxygen gas to produce carbon dioxide gas and water molecule.

\text{hydrocarbon}+O_2\rightarrow CO_2+H_2O

The chemical equation for the combustion of ethyl chloride follows:

4C_2H_5Cl+13O_2\rightarrow 2Cl_2+8CO_2+10H_2O

We are given:

When 4 moles of ethyl chloride is burnt, 5145 kJ of heat is released.

For an endothermic reaction, heat is getting absorbed during a chemical reaction and is written on the reactant side.

A+\text{heat}\rightleftharpoons B

For an exothermic reaction, heat is getting released during a chemical reaction and is written on the product side

A\rightleftharpoons B+\text{heat}

So, the chemical equation follows:

4C_2H_5Cl+13O_2\rightarrow 2Cl_2+8CO_2+10H_2O+5145kJ

Hence, the chemical equation is written above.
