The answer is- The order of decreasing potential energy is :
![CO_{2}(g) > Mg(OH)_{2} (s) > MgCO_{3} (s)](https://tex.z-dn.net/?f=CO_%7B2%7D%28g%29%20%3E%20Mg%28OH%29_%7B2%7D%20%28s%29%20%3E%20MgCO_%7B3%7D%20%28s%29)
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,
reacts with acidic
, 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
[H2O is not considered]

Answer: Bromide is many orders of magnitude better than fluoride in leaving group ability
Explanation:
As Size of an atom Increases, the Basicity Decreases this is because if we move downwards from the top of the periodic table to the bottom of the periodic table, the size of an atom increases. As size increases, basicity will decrease, meaning the element will be less likely to act as a base implying that the element will be less likely to share its electrons.
in the same vein. With an increase in size, basicity decreases, making the ability of the leaving group to leave increase to increase . This can be seen in the halogens going down the group from
F--- worst
Cl----fair
Br ----good
I-----excellent
with fluorine having the worst ability to leave than Bromine which is better in terms of the leaving group ability.
Answer:
Explanation: Water cycles through the biosphere as part of the water cycle. ... For example, gravity also pulls water from higher elevations in mountains and hills to low lying areas, whether these areas are oceans, lakes, or simply land (in which case the water is likely absorbed by plants or evaporates).

Hope it helped :))
Answer:
![2CH_3OH_{(l)} + 3O_2_{(g)} --> 2CO_2_{(g)} + 4H_2O_{(g)}](https://tex.z-dn.net/?f=2CH_3OH_%7B%28l%29%7D%20%2B%203O_2_%7B%28g%29%7D%20--%3E%202CO_2_%7B%28g%29%7D%20%2B%204H_2O_%7B%28g%29%7D)
Explanation:
The reaction between methanol and oxygen can be expressed as an equation below:
![CH_3OH + O_2 --> CO_2 + H_2O_](https://tex.z-dn.net/?f=CH_3OH%20%2B%20O_2%20--%3E%20CO_2%20%2B%20H_2O_)
However, the equation is not balanced as the number of the molecule of each atom on the right-hand side and the left-hand side is not the same. The balanced equation showing the phases of all the reactants and products is as below:
![2CH_3OH_{(l)} + 3O_2_{(g)} --> 2CO_2_{(g)} + 4H_2O_{(g)}](https://tex.z-dn.net/?f=2CH_3OH_%7B%28l%29%7D%20%2B%203O_2_%7B%28g%29%7D%20--%3E%202CO_2_%7B%28g%29%7D%20%2B%204H_2O_%7B%28g%29%7D)
<em>Two molecules of liquid methanol react with three molecules of oxygen gas to give 2 molecules of carbon dioxide gas and four molecules of water vapor. </em>
C... The number of neutrons ranges from 1H with 0 neutron, 2H with 1 neutron and 3H with 2 neutrons.
