Answer:1) Volume of 
required is 55.98 mL.
2) 0.62577 grams of 
is produced.
Explanation:
1) Molarity of 
Volume of 
Molarity of 
Volume of 
According to reaction, 1 mole of 
reacts with 3 mole of , then, 0.0041985 moles of will react with:
moles of that is 0.0125955 moles.
Volume of required is 55.98 mL.
2)
Number of moles of 
According to reaction, 3 moles of gives 1 mole of , then 0.004485 moles of will give:
moles of that is 0.001495 moles.
Mass of =
Moles of × Molar Mass of
= 0.001495 moles × 418.58 g/mol = 0.62577 g
0.62577 grams of is produced.
Answer:
The rate of acceleration is 5.
Explanation:
In order to calculate acceleration we need to divide the force by the mass.
Acceleration = net force/mass
In this case, it would be 20/4. Simplify that and we get 5.
Answer:
pH 4
Explanation:
Firstly, we define pH as the negative logarithm to base 10 of the concentration of hydrogen ions.
Mathematically, we express this as:
pH = -log[H+]
Now let’s us calculate the concentration of hydrogen in each of the pH
For pH 4, we have:
4 = -log[H+]
[H+] = -Antilog(4)
[H+] = 0.0001M
For pH 5,
[H+] = -Antilog(5)
[H+] = 0.00001M
We can see that 0.0001 is greater than 0.00001 and thus it has a greater concentration of hydrogen ions
