PH scale is used to determine how acidic or basic a solution is.
we have been given the hydrogen ion concentration. Using this we can calculate pH,
pH = - log[H⁺]
pH = - log (1 x 10⁻¹ M)
pH = 1
using pH can calculate pOH
pH + pOH = 14
pOH = 14 - 1
pOH = 13
using pOH we can calculate the hydroxide ion concentration
pOH = - log [OH⁻]
[OH⁻] = antilog(-pOH)
[OH⁻] = 10⁻¹³ M
hydroxide ion concentration is 10⁻¹³ M
Answer:
Maria
Explanation:
The gravity of the earth is so strong it causes the magnetic pull of anything and everything, this causing the ball to be dropped and pulled towards earth
This works because it demonstrates that as volume increases, pressure decreases (inverse relationship)
Answer:
Krypton has 4 orbital shells
<u>Extra Information:</u>
<em>Krypton has 36 electrons which are arranged in these 4 orbit shells, </em>
<em>The order in which electrons are arranged in these shells is 2,8,18,8</em>
Answer:
The rate of reaction increases when the reaction is catalyzed by using catalyst.
Explanation:
Catalyst is a specie which when involved in reaction, speeds up the reaction without consuming itself. The catalyst is regenerated at the end of reaction and is recovered in good yield. Catalyst main role in reaction is to decrease the Activation energy of the reaction. This decrease in activation is achieved through different mechanisms. Without going in detail, they are as follow,
1) By providing different pathway to reaction
2) By weakening the bonds
3) By providing surface area to reactants
