If a 3.50g sample of the hydrate of copper (II) sulfate is heated to yield 2.10g of anhydrous copper (II) sulfate, the mass percent of water in the hydrate is 40%.
<h3>How to calculate mass percent?</h3>
The mass percent of hydrate in a sample can be calculated by dividing the mass of water in the sample by the mass of the hydrated compound.
According to this question, 3.50g sample of an hydrate of copper (II) sulfate is heated to yield 2.10g of anhydrous copper (II) sulfate. The mass percent of water is calculated as follows:
Mass percent of water = (3.5-2.1)/3.5 × 100
Mass percent of water = 40%
Therefore, if a 3.50g sample of the hydrate of copper (II) sulfate is heated to yield 2.10g of anhydrous copper (II) sulfate, the mass percent of water in the hydrate is 40%.

Answer:
43.89 min
Explanation:
Given that:-
The speed of light =
The distance =
The conversion of distance in km to distance into m is shown below as:-
1 km = 1000 m
So,
Distance =
The relation between speed distance and time is shown below as:-
Thus,
Time = 2633.33 seconds
Also, 1 s = 1/60 min
So,
Time=
Answer: As magma cools and crystallizes minerals form is predictable patterns in a process known as '<em>Bowen reaction series'.</em>
Explanation:
The sequence in which minerals crystallize out from the magma is Bowen's reaction series. The top most layer of the magma will crystallize first and slowly successive layers will cool down to form crystals.
The newly formed mineral from the cooling magma reacts again with the remaining magma further to form another series of minerals.
all of above in order to conclude this scientific experiment
