Answer:
A. 0.35 M
Explanation:
Hello,
In this case, given the volume and concentration of lithium hydroxide and the volume of chloric acid, we can compute the concentration of the neutralized acid by using the following equation:
![n_{acid}=n_{base}\\\\V_{acid}M_{acid}=V_{base}M_{base}\\\\M_{acid}=\frac{V_{base}M_{base}}{V_{acid}} =\frac{46.9mL*0.75M}{100mL}\\ \\M_{acid}=0.35M](https://tex.z-dn.net/?f=n_%7Bacid%7D%3Dn_%7Bbase%7D%5C%5C%5C%5CV_%7Bacid%7DM_%7Bacid%7D%3DV_%7Bbase%7DM_%7Bbase%7D%5C%5C%5C%5CM_%7Bacid%7D%3D%5Cfrac%7BV_%7Bbase%7DM_%7Bbase%7D%7D%7BV_%7Bacid%7D%7D%20%3D%5Cfrac%7B46.9mL%2A0.75M%7D%7B100mL%7D%5C%5C%20%5C%5CM_%7Bacid%7D%3D0.35M)
Therefore, answer is A. 0.35 M.

Answer: Option B
Explanation: when strong acid react with strong base, the resulting solution is neutral as in the case of HCl and NaOH
HCl + NaOH —> NaCl + H2O
From the equation obtained, The salt ( NaCl) obtained is a normal salt which is neutral.
Internuclear distance can be defined as the distance between the nuclei atoms, i.e.,the distance between the center of nucleus to the outer most shell of an atom.
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.
