1) Why are the antimony and beryllium ions so small? Differentiate between the causes.
Viefleur [7K]
1. For this question, the adjective small must be percepted in a relative sense. This is because it is not the smallest ion (that would be hydrogen). It could be that the antimony and beryllium ions are smaller compared to their neutral forms. This is because they donate electrons when ionized. As a result, the electrons are reduced, so does the electron cloud which makes the radius much smaller.

2. The periodic table is arranged in terms of increasing atomic number. For neutral atoms, the number of protons (atomic number) is equal to the number of electrons. So, the farther we go down the table, the higher the atomic number. The higher the atomic number, the bigger the electron cloud which makes the atomic radius bigger. Because by definition, atomic radius is the length from the nucleus to the farthest electron from the nucleus.

What is the final, balanced equation that is formed by combining these two half reactions?
lara31 [8.8K]

Answer: Balanced equation that is formed by combining these two half reactions is Cu + NO^{-}_{3} + 2H^{+} \rightarrow Cu^{2+} + NO^{-}_{2} + H_{2}O.

Explanation:

A chemical equation which contains same number of atoms on both reactant and product side is called a balanced chemical equation.

For example, Cu \rightarrow Cu^{2+} + 2e^{-}

NO^{-}_{3} + 2e^{-} + 2H^{+} \rightarrow NO^{-}_{2} + H_{2}O

On cancelling the common species from both these half-reactions, the complete balanced equation will be as follows.

Cu + NO^{-}_{3} + 2H^{+} \rightarrow Cu^{2+} + NO^{-}_{2} + H_{2}O

Thus, we can conclude that balanced equation that is formed by combining these two half reactions is Cu + NO^{-}_{3} + 2H^{+} \rightarrow Cu^{2+} + NO^{-}_{2} + H_{2}O.

How important is it for scientists and engineers to be able to control the design of
Hatshy [7]

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.
