The answer is- The order of decreasing potential energy is :

CO_{2}(g) > Mg(OH)_{2} (s) > MgCO_{3} (s)

The potential energy can be expressed as the static energy that is stored in the chemical bonds.

What is the trend of potential energy in an exothermic reaction and an endothermic reaction?

  • During an exothermic reaction, heat is released and the stored potential energy of bonds is converted into the kinetic energy and thus there is a decrease in the potential energy during an exothermic reaction.
  • During an endothermic reaction, heat is absorbed during the reaction and this heat is stored as potential energy in bond, hence the potential energy increases during a endothermic reaction.
  • Now, during this reaction, basic Magnesium hydroxide, Mg(OH)_{2}reacts with acidic CO_{2}, thus this reaction is an exothermic reaction.
  • Hence, the potential energy of products is less than the potential of reactants.
  • Next, the potential energy of solids are always more than the potential energy of gases.
  • Therefore, the decreasing order of potential energy is

CO_{2}(g) > Mg(OH)_{2} (s) > MgCO_{3} (s)   [H2O is not considered]

Formulae for calculating number of moles​
Tresset [83]
You would use this number, 6.02×1023 (Avogadro's number) to convert from particles, atoms, or molecules to moles. Whenever you go to the mole, divide by Avogadro's number. When you go to the unit from moles, multiply by Avogadro's number.

Convert 27.7 kilometers to centimeters.
Stolb23 [73]

Answer:

The correct answer is - 2770000 cm.

Explanation:

1 kilometer = 1000 meter

1 meter = 100 centimeter

1 kilometer = 100*1000 cm

1 km = 100000 cm.

then,

27.7 kilometers = 2.77 × 10^6 centimeters

So, 27.7 kilometers = 27.7 × 100000

= 2.77 × 106 or 2770000 centimeters.

Mazyrski [523]

The rate law for this reaction is [A]².

Balanced chemical reaction used in this experiment: A + B → P

The reaction rate is the speed at which reactants are converted into products.

Comparing first and second experiment, there is no change in initial rate. The concentration of reactant B is increased by double. Initial rate does not depands on concentration of reactant B.

Comparing first and third experiment, initial rate is nine times greater, while concentration of reactant A is three times greater. Conclusion is that concentration of reactant A is squared and the rate is [A]².
