Answer:
= 29.64 g NaNO3
Explanation:
Molarity is given by the formula;
Molarity = Moles/Volume in liters
Therefore;
Number of moles = Molarity × Volume in liters
= 1.55 M × 0.225 L
= 0.34875 moles NaNO3
Thus; 0.34875 moles of NaNO3 is needed equivalent to;
= 0.34875 moles × 84.99 g/mol
= 29.64 g
The statement is true. If a mineral lacks the presence of iron in it then it will be generally dimagnetic. It means non iron minerals do not show magnetic property in general. There are some minerals like serpentine do show some magnetic susceptibility, however this is negligible as compared to iron minerals hence the ores with no magnetic are generally diamagnetic.
16) you can tell which craters are younger by them being small and you can tell which craters are older by them being larger.
17) The larger craters experienced energetic impacts because they are simply larger in size which makes them being impacted.
Hope this was helpful have a nice day :)
The oxidation half equation is Zn ------> Zn^2+ + 2e while the reduction half equation is Cu^2+ + 2e------> Cu.
A redox reaction is a reaction in which there is a loss/gain of electrons. The specie that gives out electrons experiences an increase in oxidation number while the specie that gains the electrons experiences a decrease in oxidation number.
For the reaction; CuCl2 + Zn → ZnCl2 + Cu
The oxidation half equation is;
Zn ------> Zn^2+ + 2e
The reduction half equation is;
Cu^2+ + 2e------> Cu
The chloride ion is excluded because its oxidation number does not change from left to right in the reaction.
