Answer:
D
Explanation:
We have to bear in mind that the acid is a weak acid. A weak acid does not dissociate completely in solution. We will have more concentration of undissociated acid than A^- and H3O^+ and OH^- in the system at equilibrium.
Being a weak acid, there is maximum concentration of water molecules followed by that of undissiociated acid.
Hence, for this solution, the concentration of ions in solution follows the order;
[H2O] > [HA] > [A-] ~ [H3O ] > [OH-]
Answer:
Neon and Methane
Explanation:
Nitrogen and Oxygen made up way over half of the atmosphere so it's without a doubt, not those two. Precisely, Nitrogen makes up 78% of the atmosphere while oxygen makes up 21%
<u>Answer:</u>
<em>We know water can exist in all three states be it solid or liquid or gas the only difference between the three states is the temperature at which they exist. </em>
<u>Explanation:</u>
When the temperature moves towards colder region the state of water changes to solid while when the temperature moves to water region the state of water changes to gas.
This little experiment can be done with the help of ice at room temperature. The more ice is applied to water it will turn to ice but removal of eyes in room temperature. And will make it turn to water and complete removal of eyes with application of heat would make it into vapour.
Answer:
1.) Single Displacement Reaction
2.) Synthesis Reaction
3.) Single Displacement Reaction
4.) Decomposition Reaction
5.) Double Displacement Reaction
Explanation:
Single Displacement Reaction: a reaction in which an element is swapped out for another in a molecule
Double Displacement Reaction: a reaction in which the cation of one molecule is swapped out with the cation of another
Decomposition Reaction: a reaction in which a molecule breaks down into smaller molecules/atoms
Synthesis Reaction: a reaction in which atoms or molecules come together to create a larger molecule
<h2>Answer:</h2>
<u>The statement is </u><u>true</u>
<h2>Explanation:</h2>
When we add a catalyst to a system, both the forward and reverse reaction rates will speed up equally at the same time thereby allowing the system to reach equilibrium faster. But one thing that is very important to keep in mind that the addition of a catalyst has no effect on the final equilibrium position of the reaction because it only makes the reaction faster and nothing else.
