First, calculating the amount of zinc carbonate by multiplying the given mass of the ore by the percent zinc carbonate.
mass of zinc carbonate = (976 tons)(0.78)
= 761.28 tons
Then, calculate for %Zn in zinc carbonate
%Zn = ((65.38) / (125.39)) x 100%
% Zn = 52.141%
tons of Zn from the sample,
mass of Zn = (761.28 tons)(0.52141)
= 396.94 tons Zn
True
As the shorter the bond, the stronger it is hence more energy will be required to overcome this bond
Chris is correct because the reactants and products do not have to have the same mass, but they do have to weigh the same. Is the correct answer:) Hannah is right because the mass of the reactants was different than the mass of the products. is incorrect
A. easily combines chemically with other substances is your answer.
Find the average of these 2 temperatures, since they have the same volume.
(80 + 10) ÷ 2 = 90 ÷ 2 = 45°C
You can only use this method of averaging them out because they have the same volumes :)
