This download is my science worksheet. It's about different types of energy in a situation, like examples. btw this is 7th grade
scoray [572]

All types of energy can be resumed into two basic types of energy which include kinetic energy and potential energy.

<h3>What is kinetic energy?</h3>

Energy is the ability to perform a given work. Kinetic energy is energy in movement, whereas potential energy is stored energy.

For example, plant photosynthesis makes reference to chemical energy (potential energy), popcorn makes reference to thermal energy, etc.

In conclusion, all types of energy can be resumed into two basic types of energy which include kinetic energy and potential energy.

Given the equilibrium constants for the following two reactions at a 298K:NiO(s) + H2(g) ⇌ Ni(s) + H2O(g) Kc=40NiO(s) +CO(g) ⇌ N
shusha [124]

Answer:

The value  is  K_C =  \frac{40}{600}

Explanation:

From the question

   The equation given is  

            NiO(s) + H2(g) ⇌ Ni(s) + H2O(g) Kc=40          (1)

            NiO(s) +CO(g) ⇌ Ni(s) +CO2(g) Kc=600         (2)

Generally the reverse of the second equation as shown below

            Ni(s) +CO2(g) ⇌  NiO(s) + CO(g)                 (3)

The equilibrium constant becomes    K_c  ' =  \frac{1}{600}  

 Now  adding  1  and  3 we obtain

      NiO(s) + H2(g)+ Ni(s) +CO2(g) ⇌ Ni(s) + H2O(g)+NiO(s) + CO(g)        

               CO2(g) + H2(g) ⇌ CO(g) + H2O(g)

Hence the equilibrium constant for the resulting equation is mathematically evaluated as

           K_C =  K_c' *  K_c

=>       K_C =  \frac{1}{600}  *  40

=>         K_C =  \frac{40}{600}

A 0.63 mole sample of CO2 is in a 750 mL container. What is the pressure of the gas in torr when the has is held at -35.6oC?
kipiarov [429]

Answer:

12426torr

Explanation:

The following data were obtained from the question:

n = 0.63 mole

V = 750mL = 750/1000 = 0.75L

T = -35.6°C = -35.6 + 273 = 237.4K

R =0.082atm.L/Kmol

P =?

Using the ideal gas equation PV = nRT, the pressure can be obtained as follows:

PV = nRT

P = nRT/V

P = (0.63 x 0.082 x 237.4)/0.75

P = 16.35atm

Now let us convert this pressure (i.e 16.35atm) to a pressure in torr. This is illustrated below:

1atm = 760torr

16.35atm = 16.35 x 760 = 12426torr

Therefore, the pressure of the gas is 12426torr
