Assuming that there is missing information in this question I’m just going to go ahead and say that it’s lower.
HNO3 (nitric acid) is a very strong acid which should be found on the lower end of the pH scale. While water, on the other hand, is neutral and found at a pH of 7.
So if you add one drop of a strong acid into a neutral solution of 100ml let’s say, one can assume that the pH of that solution is now very low and probably found between 1-3 on a pH scale.
Reminder:
-Acids are found between 1-6 on the pH scale. The lower the number the stronger the acid
-Bases are found between 8-14 on the pH scale. The higher the number the stronger the base
Answer: 6.71 g
Explanation: 
Limiting reagent is the reagent which limits the formation of product. Excess reagent is one which is in excess and thus remains unreacted.
Thus lithium is the limiting reagent and nitrogen is the excess reagent.
As can be seen from the balanced chemical equation, 6 moles of lithium reacts with 1 mole of nitrogen to give 2 moles of lithium nitride.
Thus 0.578 moles of lithium react with 0.096 moles of nitrogen.
6 moles of lithium give = 2 moles of lithium nitride
Thus 0.578 moles of lithium give=
of lithium nitride.
Mass of lithium nitride

tbh id k i've never read it so if u could send the link I could help you.
Explanation:
Answer:
9.86*10^(-3) g
Explanation:
PbSO4 ----> Pb^(2+) + SO4^(2-)
s s
Ksp = s²
s =√Ksp = √(1.8*10^-8) = 1.3*10^(-4) mol/L
The molar solubility PbSO4 = 1.3*10^(-4) mol/L.
2.50 *10^2 mL *1L/10³mL =0.250L
1.3*10^(-4)mol/L *0.250L*303.3 g/mol = 9.86*10^(-3) g
reactivity! when something reacts to another substance, its a chemical change. When something melts, boils, or changes color, it is still the same substance, therefore is physical
