Answer:
pH = 3; acidic
Explanation:
The equation to find pH given [H+] is:
pH = -log[H+]
In the question it gives us the concentration of [H+], which is 0.0010 M.
Now just plug this into the equation to solve:
pH = -log(0.0010)
pH = 3
This would make the solution acidic as it is less than 7.
Hope this helps!!
Answer:
Would be increasing the concentration of SO3 as you chose in the question.
Explanation:
Increasing the concentration of the reactant will most likely shift it to the right by adding more products.
The pressure of the oxygen gas collected : 718 mmHg
<h3>Further explanation</h3>
Given
P tot = 748 mmHg
P water vapour = 30 mmHg
Required
P Oxygen
Solution
Dalton's law of partial pressures states that the total pressure of a mixture of gases is equal to the sum of the partial pressures of the component gases
Can be formulated:
P tot = P1 + P2 + P3 ....
The partial pressure is the pressure of each gas in a mixture
P tot = P H₂O + P Oxygen
P Oxygen = 748 mmHg - 30 mmHg
P Oxygen = 718 mmHg
A. Fewer valence electrons
Valence electrons are electrons that are held most loosely in the outermost shell.
<u>Answer:</u> The rate law for the reaction is ![\text{Rate}=k[NO_3][CO]](https://tex.z-dn.net/?f=%5Ctext%7BRate%7D%3Dk%5BNO_3%5D%5BCO%5D)
<u>Explanation:</u>
Rate law is defined as the expression which expresses the rate of the reaction in terms of molar concentration of the reactants with each term raised to the power their stoichiometric coefficient of that reactant in the balanced chemical equation.
In a mechanism of the reaction, the slow step in the mechanism determines the rate of the reaction.
For the given chemical reaction:
The intermediate reaction of the mechanism follows:
Step 1: 
Step 2: 
As, step 2 is the slow step. It is the rate determining step
Rate law for the reaction follows:
Hence, the rate law for the reaction is written above.
