A balloon is a sphere with a radius of 5.0 m. The force of air against the walls of the balloon is 45 N. What is the air pressure inside the balloon? (surface area = 12.56 x radius^2; 1 Pa = 1 N/m^2)A. 1.4 x 10^3 Pa

B. 3.6 x 10^2 Pa

C. 1.4 x 10^-1 Pa

D. 3.6 x 10^-2 Pa

***Idk how to solve this... pls explain?? thx :)

Answers

Answer 1

Answer: Pressure is the force exerted on an object per unit area. The equation is expressed as:

P = F / A

From the given above, we substitute the values to the equation.

P = F/A
P= F / (12.56r²)
P = 45 N / (12.56 x 5²
P = 0.143 N/m²

Therefore, the correct answer is option C, 1.4 x 10^-1 Pa.

Which sequence describes the result of increasing the number of gas particles in a container? A.) fewer collisions --> lower collision force --> lower pressure B.)more collisions --> lower collision force --> lower pressure. C.) fewer collisions --> greater collision force -->higher pressure. D.)more collisions --> greater collision force --> higher pressure

Answers

Answer: Option (D) is the correct answer.

Explanation:

It is known that relation between pressure and force is that, pressure equals force divided by area.

Mathematically, P = $(F)/(a)$

where P = pressure

F = force

a = area

Hence, when there is increase in number of gas particles in a container the there will be more number of collisions due to increase in number of particles. This will lead to greater collision force and as a result there will be increase in pressure because force is directly proportional to pressure.

Thus, we can conclude that the sequence more collisions --> greater collision force --> higher pressure best describes the result of increasing the number of gas particles in a container best describes the result of increasing the number of gas particles in a container.

I believe the correct response is D. More collisions that result in greater collision force and higher pressure.

How will an energy diagram look for an exothermic reaction?The reactants and products will be at the same potential energy.

The reactants are at a higher potential energy compared to the products.

The reactants are at a lower potential energy compared to the products.

There will not be an activation energy barrier.

Answers

Answer : The correct option is, The reactants are at a higher potential energy compared to the products.

Explanation :

Exothermic reaction means energy is released and the overall enthalpy change is negative.

In exothermic reaction, the reactants are at a higher potential energy compared to the products. In other words, we can say that the products are more stable than the reactants.

B.) The reactants are at a higher potential energy compared to the products.

My reason being is because the reactants tend to gather "hyper" energy which is also known as potential energy and this will occur as shown in the answer as an Exothermic Reaction.

I really hope that this helps you out a lot. Have a nice day :)

Answers

The statements that are correct are ‘A large Keq value indicates that products are favored.’ And ‘A small Keq value indicates that the reverse reaction will occur very quickly.’ Having large Keq means that the concentration of the product is greater than the reactants and so products are favored. Having small Keq means that the concentration of the reactants is greater than the product.
