It is important for scientists and engineers to be able to control the design of the material because<u> it create solutions to problems</u>.
<h3>Why material science and engineering is important?</h3>
What things are made of and why they behave the way they do are lessons we learn from materials science. Materials engineering teaches us how to use knowledge to improve things and the way they are made. Research and industry innovation in fields as diverse as aerospace and medicine are driven by materials science and engineering.
<h3>Why is it important for scientists to use the scientific method?</h3>
The scientific method is essential because: It follows a set of rules. Scientists conduct experiments in a standardized manner because the steps used in the scientific method are systematic. This suggests that their research might be spread widely.

Boyle’s = increase as volume decreases
Charles = increases and pressure increases
Gay-lussacs = increases as pressure increases
C. heat tends to balance out and it must travel to cooler areas to balance out the temp
If you are provided with Cation and an Anion with different oxidation states, then there ratio in the formula unit is adjusted as such that the oxidation number of one ion is set the coefficient of other ion and vice versa,
Example:
Let suppose you are provided with A⁺² and B⁻¹, so multiply A by 1 and B by 2 as follow,
A(B)₂
In statement we are given with Co⁺³ and SO₄⁻², so multiply Co⁺³ by 2 and SO₄⁻² by 3, hence,
Co₂(SO₄)₃
Result:
Co₂(SO₄)₃ is the correct answer.
