Answer:
Electrons are particles that surround the nucleus of an atom like a cloud. As with protons and neutrons, electrons are essential to an atom's structure.
Answer:
It produces magnesium oxide and hydrogen gas.
Explanation:
When magnesium burns with steam it produces magnesium oxide which is white in color and hydrogen gas. When magnesium burns, it mixes with the oxygen present in the air produces magnesium oxide in powder form. Magnesium react with oxygen by giving two electrons present in its valance shells while the oxygen needs two electron for completing their valance shell and becomes stable.
Polymerization
For example:
nCH₂=CH₂ ---p,T,kat.----> -[-CH₂-CH₂-]- n
Explanation:
dU=TdS-pdV (given)
To prove = 1) 
(at constant U)
2) 
(at constant V)
Solution: 1)
dU=TdS-PdV
Derivative of constant is zero.
Given that internal energy is ,U = constant
(hence proved)
Solution: 2)
dU=TdS-PdV
Differentiating with respect to dU, we get:
Derivative of constant is zero.
Given that volume is constant , V= constant
(hence proved)
