In science, you will use a graduated cylinder to measure a liquid's volume. Graduated cylinders are used to measure liquid volume because it is the instrument with the greatest accuracy. Liquids do not sit level in a container. Because of this, the surface of a liquid in any container is curved.

In a certain chemical reaction Compound A combines with Compound B to produce Compound C (and no other products). Measurements w
Karo-lina-s [1.5K]

Answer:

Theoretical yield of C = 7.9 g

Actual amount of C isolated = 5.0 g

Explanation:

Given that in the reaction, Compound A combines with Compound B t o produce Compound C and no other products, the reaction is a combination reaction. The equation of the reaction is given below:

A + B ---> C

Part A:

From the measurement of the masses of A and B present before and after the reaction, the following values were obtained:

Initial mass of A = 4.0 g

Final mass of A = 0.0 g

Mass of A used up + 4.0 - 0.0 = 4.0 g

Initial mass of B = 9.0 g

Final mass of B = 5.1 g

Mass of B used up = 9.0 - 5.1 = 3.9 g

According to the law of conservation of mass, matter can neither be created nor destroyed but can change from one form to another. Therefore, theoretical yield of C equal the sum of the masses of A and B used up.

Theoretical yield of C = 4.0 + 3.9 = 7.9 g

Part B:

Given that the percent yield is 63.0 % = 0.63

Actual amount of C isolated = 0.63 * 7.9 = 5.0 g

The amount of energy needed to raise one gram of a substance one degree Celsius is a characteristic property known as
natita [175]

Answer : The amount of energy needed to raise one gram of a substance one degree Celsius is a characteristic property known as, Specific heat capacity.

Explanation:

Heat capacity : It is defined as the heat required to raise the temperature by one degree.

Specific heat capacity : It is defined as the amount of heat required by one gram of a substance to raise its temperature by one degree Celsius.

The heat required to change the temperature of a substance is related to heat capacity of the substance by the expression as :

C=\frac{q}{m\times \Delta T}

where,

C = specific heat capacity

m = mass of a substance

q = heat required

\Delta T = change in temperature of substance

Hence, the amount of energy needed to raise one gram of a substance one degree Celsius is a characteristic property known as, Specific heat capacity.
