Answer : The number of moles of solute 
is, 0.0788 moles.
Explanation : Given,
Molarity = 0.225 M
Volume of solution = 0.350 L
Formula used:
Now put all the given values in this formula, we get:
Therefore, the number of moles of solute is, 0.0788 moles.
Answer:
True
Explanation:
If a question cannot be tested and observed, it cannot simply be answered by science.
Science works with observable and testable ideas and not on metaphysics.
- Science presents a methodical approach into investigating phenomenon and answering likely questions in a logical manner.
- The body of facts and data gathered through observations and tests are used to ramify the conclusion of a scientific study.
- Without such, it is impossible to do the work of science.

Answer:
SeCl₆ < SeF₂ < SeO₂
Explanation:
(A) SeO₂
The central atom has 2 bond pairs and 1 lone pair. The molecule is bent shaped which has an angle of 120°.
(B) SeCl₆
The central atom has 6 bond pairs and 0 lone pair. The geometry is octahedral in which the equatorial bonds has an angle of 90° and axial bond has an angle of 90°.
(C) SeF₂
The central atom has 2 bond pairs and 2 lone pairs. The geometry is bent shape which has an angle of approximately 105.5°.
The order is:
<u>SeCl₆ < SeF₂ < SeO₂</u>
