Answer:
F=ma
Explanation:
F=m×a
according to that F÷m=a and also F ÷a=m

Answer:
C. Br and Cl
Explanation:
The pair that will share electrons when a bond forms between them is Br and Cl.
When electrons are shared between two atoms to form a bond, then the bond type formed is called a covalent bond.
- A covalent bond forms between non-metals.
- Br and Cl are non-metals
- The electronegativity difference between the species must be very low or zero.
- This is the case for the two non-metals.
Answer:
Passivation of Oxide layers of the metals.
Explanation:
Passivation is a non-electrolytic finishing process that makes most metals rust-resistant. The prosses removes free iron from the surface by using either nitric or citric acid. When this happens, it results to an inert, protective oxide layer that is very slow or less likely to chemically react with air and cause corrosion.
Passivity caused many of the metals several minutes to begin to react. Once the finishing process that makes metals less likely to react was eroded, reaction was initiated vigorously.
