Question

answer the following​

Answer 1

Answer:

1) When the bullet strikes the target there is heat generated because the kinetic energy of the moving bullet is transformed into heat energy due to the friction etc. between bullet and target.

3) Valency of carbon is 4. The outer electronic configuration of carbon is 2s

2

2p

2

. Thus, it has 4 valence electrons. It shares these 4 valence electrons to form 4 covalent bonds. Hence, valency of carbon is 4. For example in compounds like CH4

and CO2

, valency of carbon is 4.

Answer 2

Answer:

hi friend here is your answer

Explanation:

1) When the bullet strikes the target there is heat generated because the kinetic energy of the moving bullet is transformed into heat energy due to the friction etc. between bullet and target.

2) Copper has the best electrical conductivity of any metal, except silver. A good electrical conductivity is the same as a small electrical resistance. An electric current will flow through all metals, however they still have some resistance, meaning the current needs to be pushed (by a battery) in order to keep flowing.

3) Valency of carbon is 4. The outer electronic configuration of carbon is 2s22p2. ... It shares these 4 valence electrons to form 4 covalent bonds. Hence, valency of carbon is 4.

I hope this helps you ...

Thankyou

have a nice day
