What is the initial temperature (in Celsius) of a 675 ml balloon if the
RoseWind [281]

Answer: 127 (3.s.f)

Explanation:

Boyle's law states that Volume x pressure = constant

Therefore let's first find the constant: 45 x 1900 = 85500

Then lets plug 675 ml and 85500 into the equation above:

675 x C = 85500

C = 127 (3 s.f.)

When you combine 50.0 mL of 0.100 M AgNO3 with 50.0 mL of 0.100 M HCl in a coffee-cup calorimeter, the temperature changes from
RideAnS [48]

Answer : The enthalpy of reaction (\Delta H_{rxn}) is, 67.716 KJ/mole

Explanation :

First we have to calculate the moles of AgNO_3 and HCl.

\text{Moles of }AgNO_3=\text{Molarity of }AgNO_3\times \text{Volume}=(0.100mole/L)\times (0.05L)=0.005mole

\text{Moles of }HCl=\text{Molarity of }HCl\times \text{Volume}=(0.100mole/L)\times (0.05L)=0.005mole

Now we have to calculate the moles of AgCl formed.

The balanced chemical reaction will be,

AgNO_3(aq)+HCl(aq)\rightarrow AgCl(s)+HNO_3(aq)

As, 1 mole of AgNO_3 react with 1 mole of HCl to give 1 mole of AgCl

So, 0.005 mole of AgNO_3 react with 0.005 mole of HCl to give 1 mole of AgCl

The moles of AgCl formed  = 0.005 mole

Total volume of the solution = 50.0 ml + 50.0 ml = 100.0 ml

Now we have to calculate the mass of solution.

Mass of the solution = Density of the solution × Volume of the solution

Mass of the solution = 1.00 g/ml × 100.0 ml = 100 g

Now we have to calculate the heat.

q=m\times C\Delta T=m\times C \times (T_2-T_1)

where,

q = heat

C = specific heat capacity = 4.18J/g^oC

m = mass = 100 g

T_2 = final temperature = 24.21^oC

T_1 = initial temperature = 23.40^oC

Now put all the given values in the above expression, we get:

q=100g\times (4.18J/g^oC)\times (24.21-23.40)^oC

q=338.58J

Now  we have to calculate the enthalpy of the reaction.

\Delta H_{rxn}=\frac{q}{n}

where,

\Delta H_{rxn} = enthalpy of reaction = ?

q = heat of reaction = 338.58 J

n = moles of reaction = 0.005 mole

Now put all the given values in above expression, we get:

\Delta H_{rxn}=\frac{338.58J}{0.005mole}=6771.6J/mole=67.716KJ/mole

Conversion used : (1 KJ = 1000 J)

Therefore, the enthalpy of reaction (\Delta H_{rxn}) is, 67.716 KJ/mole

The picture shows two containers filled with a gas.
Irina18 [472]

The average kinetic energy of the gas particles is greater in container B because it has a higher temperature.

<h3>What is temperature?</h3>

The term temperature refers to a measure of the average kinetic energy of the molecules of  body. This means that molecules that are at high temperature tend to move faster than the molecules that are at low temperature.

As such, the higher temperature of the molecules of the gas in B shows that the molecules in B are faster than those in A thus the correct statement is; "the average kinetic energy of the gas particles is greater in container B because it has a higher temperature."

Missing parts;

The picture shows two containers filled with a gas.

Two equally sized containers are shown with tight lids and each container has a thermometer. The container on the le is labeled A and the one on the right is labeled B. The thermometer inside container B shows a higher temperature than the thermometer inside container A.

Which statement is correct?

The average kinetic energy of the gas particles is greater in container A because it has a lower temperature.

The average kinetic energy of the gas particles is greater in container B because it has a higher temperature.

The gas particles in both containers have the same average kinetic energy because t have the same volume.

The gas particles in both containers have the same average kinetic energy because t have equal number of particles.
