Answer:
The correct answer is 150 kilograms.
Explanation:
Based on the given information, the ratio of zinc and copper within the alloy is 2:5. The amount of zinc used in the alloy is 60 kg. Now the amount of copper used within the alloy would be,
Zinc/Copper = 2/5
60/Copper = 2/5
Copper(Cu) = 60*5/2
Cu = 150 Kilograms.
Thus, the amount of Cu used in the alloy is 150 Kg.
Alpha is the -OH group at the anomeric position is down. beta is up
a. alpha
b. beta
c. beta
d. alpha
to draw the other anomer, just flip the OH at the anomeric position
Answer:
Theoretical number of moles
Explanation:
The coefficient used in balancing a chemical reaction helps to show theoretically the number of moles of reactants used or products formed. It tends to give a representation of the ratio of the number of moles of reactants and products.
What we are saying in essence is that it helps to picture the number of moles of the reactants coming into the chemical reaction or the number of moles of products formed as the reaction proceeds to completion
Technically speaking absolutely nothing but from a religious standpoint God did
the oxidation number of carbon in MgCO3 = +IV
the oxidation number of carbon in CO2 = +IV
so, there is no change
