Answer:
The pH of the HCl solution is 3.9
Explanation:
Knowing the molar mass of HCl (36.5g/mol) it is possible to calculate the number of moles of HCl in the solution,
of HCl
HCl is a strong acid and when added to water will form H+ and Cl-, thus the moles of HCl are equal to moles of H+ in 354 mL of water
The concentration of protons in the solutions is 
.
The expression used to calculate the pH is
![pH = -Log ([H^{+}]) = -Log (1.16x10^{-4} M) = 3.9](https://tex.z-dn.net/?f=pH%20%3D%20-Log%20%28%5BH%5E%7B%2B%7D%5D%29%20%3D%20-Log%20%281.16x10%5E%7B-4%7D%20M%29%20%3D%203.9)
Hence, the pH of the HCl solution is 3.9 and Pepsi has a pH of 3.4 approximately, so they have almost the same pH.
Answer:
Fossil fuels are hydrocarbons, primarily coal, fuel oil, or natural gas, formed from the remains of dead plants and animals. In common dialogue, the term fossil fuel also includes hydrocarbon-containing natural resources that are not derived from animal or plant sources.
Explanation:
fossil fuels are continually formed by natural processes, they are generally classified as non-renewable resources because they take millions of years to form, and known viable reserves are being depleted much faster than new ones are generated.
So this isn't a question but thanks for telling me...? Next time ask a question pleaseeeee.
Answer:
12 moles of F₂
Explanation:
We'll begin by writing the balanced equation for the reaction. This is illustrated below:
N₂ + 3F₂ —> 2NF₃
From the balanced equation above,
3 moles of F₂ reacted to produce 2 moles of NF₃.
Finally, we shall determine the number of mole of F₂ needed to produce 8 moles of NF₃. This can be obtained as illustrated below:
From the balanced equation above,
3 moles of F₂ reacted to produce 2 moles of NF₃.
Therefore, Xmol of F₂ will react to produce 8 moles of NF₃ i.e
Xmol of F₂ = (3 × 8)/2
Xmol of F₂ = 12 moles
Thus, 12 moles of F₂ is needed for the reaction.
