The balloon will reach its maximum volume and it will burst.

Given:

  • A weather balloon at sea level, with gas at 65.0 L volume, 745 Torr pressure, and 25C temperature.
  • When the balloon was taken to an altitude at which temperature was 25C and pressure was 0.066atm its volume expanded.
  • The maximum volume of the weather balloon is 835 L.

To find:

Whether the weather balloon will reach its maximum volume or not.

Solution:

The pressure of the gas in the weather balloon at sea level = P_1=745 torr

1 atm = 760 torr\\P_1=745 torr=\frac{745}{760} torr = 0.980 atm

The volume of the weather balloon at sea level = V_1=65.0L

The temperature of the gas in the weather balloon at sea level:

T_1=25^oC=25+273.15 K=298.15 K

The balloon rises to an altitude.

The pressure of the gas in the weather balloon at the given altitude:

P_2=0.066atm

The volume of the weather balloon at the given altitude = V_2=?

The temperature of the gas in the weather balloon at the given altitude:

T_1=25^oC=25+273.15 K=298.15 K

Using the Combined gas law:

\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}\\\frac{0.980 atm\times 65.0L}{298.15 K}=\frac{0.066atm\times V_2}{298.15K}\\V_2=\frac{0.980 atm\times 65.0L\times 298.15K}{0.066atm\times 298.15 K}\\=965L

The maximum volume of the weather balloon= V = 835 L

V < V_2

The volume of the weather balloon at a given altitude is greater than its maximum volume which means the balloon will reach its maximum volume and it will burst.

How is the rate of reaction influenced by a catalyst? how do catalysts make this possible?
Eddi Din [679]
Answer:
            The rate of reaction increases when the reaction is catalyzed by using catalyst.

Explanation:
                   Catalyst is a specie which when involved in reaction, speeds up the reaction without consuming itself. The catalyst is regenerated at the end of reaction and is recovered in good yield. Catalyst main role in reaction is to decrease the Activation energy of the reaction. This decrease in activation is achieved through different mechanisms. Without going in detail, they are as follow,
                  1) By providing different pathway to reaction

                  2) By weakening the bonds

                  3) By providing surface area to reactants

The equation that represents this reaction is Pb(NO3)2(aq) + 2 KI(aq) arrow PbI2(s) + 2 KNO3(aq). In what ways does this equatio
o-na [289]

Answer: The number of atoms remain constant and thus the  mass also remains conserved.

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

Pb(NO_3)_2(aq)+2KI(aq)\rightarrow PbI_2(s)+2KNO_3(aq)

In product side ,2KNO_3 there are 2 atoms of potassium, 2 atoms of nitrogen and 6 oxygen atoms. In PbI_2 there is 1 atom of lead and 2 atoms of iodine.

In reactant side ,Pb(NO_3)_2 there are 2 atoms of nitrogen, 6 oxygen atoms and 1 atom of lead. In 2KI there are 2 atoms of potassium and 2 atoms of iodine.

Thus the number of atoms remain constant and thus the  mass also remains conserved.
