Show the calculation of the final temperature for a 20.8 gram piece of iron heated to 100oC which has been added to a 55.3 gram
umka2103 [35]

Answer:

Final Temperature = 28.2 oC

Explanation:

Information given;

Mass of Iron = 20.8g

Initial Temperature of Iron = 100C

Mass of water = 55.3g

Initial temperature of water = 25.3 C

The presence of a coffee cup calorimeter hints that there is no heat loss to the surrounding and that the iron and water are at thermal equilibrium.

Thermal equilibrium means that there is no heat transfer going on between the bodies, which simply means that the bodies are at the same temperature.

Hence, both bodies would the same final temperature (T2)

H = M * C * ΔT (For iron)

H = 20.8 * 0.449 * ( 100 - T2)

H = 9.3392 ( 100 - T2)

H = 933.92 - 9.3392T2

H = M * C * ΔT (For water)

H = 55.3 * 4.184 * (T2 - 25.3)

H = 231.3752 (T2 - 25.3)

H = 231.3752T2 - 5853.79

Since they are in thermal equilibrium it means H (Iron) = H (water).

This leads to;

933.92 - 9.3392T2 = 231.3752T2 - 5853.79

231.3752T2 +  9.3392T2  = 5853.79 + 933.92

240.7144 T2 = 6787.71

T2 = 28.2 oC

Add one or more curved arrows to show the movement of electrons in the reaction. To draw the arrows, select More in the drawing
DIA [1.3K]

Answer:

H3C - O - O - CH -HCOCH2.

Explanation:

Before chemical reaction can occur, some steps has to be followed in order to give the final product (s), this steps can be shown by drawing the chemical compound and showing how bonds are being broken or formed. Showing this in a stepwise manner is known as reaction mechanism.

From the question above, it is given that the products after heating the reactant gives H3C—0. +.0—CH HCO CH2.

The starting material can be deduce as;

H3C - O - O - CH -HCOCH2.

Heat causes something to divide or melt. Kindly check the attached picture which shows how the deduced starting compound splits to give H3C—0. and .0—CH HCO CH2.

A sample of gas kept at a constant pressure, is heated from 273 k to 373 k. If the initial volume is 3.00 L, what is the new vol
zlopas [31]

Answer: 4.10 liters

Explanation:

Given that:

initial volume of gas V1 = 3.0L

initial temperature of gas T1 = 273K

new volume V2 = ?

new temperature T2 = 373K

Since, only volume and temperature are involved, apply the formula for Charle's law

V1/T1 = V2/T2

3.0L/273K = V2/373K

To get the value of Z, cross multiply

3.0L x 373K = 273K x V2

1119 = 273V2

Divide both sides by 273

1119/273 = 273V2/273

4.10L = V2

Thus, the new volume is 4.10 liters
