The result which occurs during an exothermic reaction is: C. Light and heat are released into the environment.

A chemical reaction is defined as a chemical process involving the continuous transformation and rearrangement of either the ionic, atomic or molecular structure of chemical elements, especially through the breakdown and formation of chemical bonds, so as to produce a new chemical compound.

Basically, the two (2) main types of chemical reaction are;

  • <u>Endothermic reaction:</u> this is a chemical reaction in which heat is absorbed .

<u>Exothermic reaction:</u> this is a chemical reaction in which light and heat is liberated (released) into the environment.

In an exothermic chemical reaction, light and heat energy is liberated (released) when the energy of the products is lesser than the energy of the reactants.

In conclusion, light and heat is liberated (released) into the environment during an exothermic reaction.

A sample of nitrogen gas had a volume of 500. ml, a pressure in its closed container of 740 torr and a temperature 25 degrees c
Semenov [28]
Question:
              <span>A sample of nitrogen gas had a volume of 500mL, a pressure in its closed container of 740 torr and a temperature of 25°c. what was the volume of gas when the temperature was changed to 50°c and the new pressure was 760 torr?

Answer:

Data Given:
                   V</span>₁  =  500 mL

                   P₁  =  740 torr

                   T₁  =  25 °C + 273  =  298 K

                   V₂  =  ?

                   P₂  =  760 torr

                   T₂  =  50 °C + 273  =  323 K

Solution:
             Let suppose the gas is acting Ideally, then According to Ideal Gas Equation,

                      P₁ V₁ / T₁  =  P₂ V₂ / T₂

Solving for V₂,

                      V₂  =  (P₁ V₁ T₂) ÷ (T₁ P₂)

Putting Values,
  
                      V₂  =  (740 torr × 500 mL × 323 K) ÷ (298 K × 760 torr)

                      V₂  =  527.68 mL

In cucumbers, green skin (G) is dominant to striped skin (g). If a farmer crosses a heterozygous (hybrid) cucumber with a homozy
Elena L [17]

Answer:

Half will be green and half will be striped

Explanation:

Given green skin (G) is dominant to striped skin (g).

Cucumber 1 : Heterozygous (Gg)

Cucumber 2 : Homozygous striped (gg)

When Gg X gg :

     G      g

g   Gg   gg

g   Gg   gg

Half of the offspring will have Gg genotype so they will be green. Other half will have gg genotype so they will be striped.
