Answer: Option (B) is the correct answer.
Explanation:
When two circles are of same same then they are known as congruent circles.
Whereas a rectangle is a kind of parallelogram with all sides equal to .
Therefore, when 2 congruent circles and 1 rectangle combines then it results in the formation of a cylinder.
Thus, we can conclude that solid formed when 2 congruent circles and 1 rectangle combines will be a circle.
Answer: 2.17 g of bromide product would be formed
Explanation:
The reaction of calcium bromide with lithium oxide will be:
To calculate the moles :
As lithium oxide is in excess, calcium bromide is the limiting reagent.
According to stoichiometry :
1 mole of produce = 2 moles of
Thus 0.0125 moles of will require=
of
Mass of
Thus 2.17 g of bromide product would be formed
