A piece of metal ore weighs 8.25 g. when a student places it into a graduated cylinder containing water, the liquid level rises
2 answers:
Answer: Option (b) is the correct answer.
Explanation:
As it is known that density is the mass present in per unit volume.
Mathematically, Density =
As initial volume is given as 21.25 ml and final volume is given as 26.47. Hence, change in volume will be calculated as follows.
Change in volume = 26.47 ml - 21.25 ml
= 5.22 ml
As mass is given as 8.25 g. Therefore, density of the given ore will be calculated as follows.
Density =
=
= 1.58 g/ml
Thus, we can conclude that density of the ore is 1.58 g/ml.

Answer : The % of (+) limonene isomer = 79%
The % of (-) limonene isomer = 0%
The % of enantiomeric excess = 58%
Explanation : Enantiomeric excess (ee) is the measurement of purity used for chiral substances.
Given,
% of pure limonene enantiomer = The % of (+) limonene isomer = 79%
Therefore, The % of (-) limonene isomer = 0%
Formula used :
Where, ee → enantiomeric excess
Now, put all the values in above formula, we get the value of enantiomeric excess (ee).
= 58%
<u>Answer:</u> The products of the reaction will be
<u>Explanation:</u>
Single displacement reaction is defined as the reaction in which more reactive element displaces a less reactive element from its chemical reaction.
The general chemical equation for the single displacement reaction follows:
The given chemical equation follows:
Bromine element is more reactive than iodine element. Thus, can easily replace iodine from its chemical reaction.
Hence, the products of the reaction will be
