Answer:
Chemical reaction A, because the reactant is a compound
Explanation:
In a decomposition reaction, a compound is broken down into its components, so the number of products is greater than the number of reactants
Can you translate in english i can’t understand this
To find out the answer, we must know the mass percentage of Cu in the mineral chalcopyrite.
Mass percentage of Cu = molar mass of Cu/molar mass of chalcopyrite = 64/(64+56+32*2) = 34.8%.
So to obtain 210 g pure Cu, the amount of mineral need = mass of Cu/mass percentage of Cu = 210 g/34.8% = 603 g = 0.603 kg.
Answer:
Q1) Mole ratio would be 1:1
For a 100% yield
761.31 g of <span>2-chloro-2,4-dimethylpentane will be produced.</span>
