<u>Answer:</u> 0.5 moles of 
are produced in the reaction
<u>Explanation:</u>
The number of moles is defined as the ratio of the mass of a substance to its molar mass.
The equation used is:
......(1)
Given mass of 
= 113.6 g
Molar mass of = 79.5 g/mol
Plugging values in equation 1:
For the given chemical reaction:
By the stoichiometry of the reaction:
If 3 moles of produces 1 mole of
So, 1.43 moles of will produce = 
of
Hence, 0.5 moles of are produced in the reaction
Answer:
1) mass and type of material
2) type of material
3) temperature
Explanation:
Answer:
The correct answer is "All chemical reactions occur at different rates".
Explanation:
The reaction speed is given by the amount of substance that is transformed into a given reaction per unit volume and time. Several factors influence the speed of a chemical reaction. One of them is the concentration of the reagents and the other the temperature, as well as the pressure.
Have a nice day!
Ok let me explain the procedure to you:
The buffer solution is like this:
pH = pKa + log [salt]/[acid]
4 = 4.20 + log [salt] / [acid]
-0.20 = log [salt]/[acid]
If you <span>Solve for [salt]/[acid]
This gives ratio of moles.
</span><span>Take amount of acid be x L and then amount of salt will be 0.1-x
Now molarity*volume=number of moles
</span>I know that with this you will be able to get to the result. Hope this helps
