The answer to this is hermatite
Answer:
Reactions:
Explanation:
In the reaction, the CrO4(Chromate) is a compound NO3(Nitrate) is a compound as well.
Ignore the number in front of the reaction first, calculate how many K, Cr, O, Pb and N in the equation for both left and right side.
Left side: K=2, Cr=1, Pb=1, N=2, O=10
Right side: K=1, Cr=1, Pb=1, N=1, O=7
So we need 3 more oxygen, 1 more nitrogen and 1 more potassium on the right.
If we add a 2 in front of KNO3, there will be 2 potassium, 2 Nitrogen and 6 oxygen, which the reaction complete.
Conclusion:
Electrical generators.
Hope this is right.
Answer:
b. 9 g
Explanation:
Solubility Ce2(SO4)3 at 10°C is a little less than 10 g/100 g water.
So, the best answer is b. 9 g.
Answer:
Sucrose 342.34
Mysristic acid 228.42
Explanation:
The first step is to write out the formula of the substance in question. Let us start with sucrose. . Then use that to help you determine the molecular weights using the relative atomic mass of each species.
molecular weight = (12.01*12) + (1.01*22) + (16.00*11) = 342.34
Be sure to write no units for this answer. This is not the molar mass, this is the relative molecular mass. It's on a relative scale not in grams
We repeat the steps above for mysristic acid, formula .
molecular weight = (12.01*14) + (1.01*28) + (16*11) = 228.42
