Hello!
If a reaction occurs when a piece of metal is placed in a solution, you can conclude that the solution is <span>probably acidic because bases rarely react with metals.
Strong Acids, like HCl, react with metals to produce salts and release gaseous hydrogen (H</span>₂) which is evidenced by the generation of bubbles in the solution. The general chemical equation for this kind of reactions for a metal M and an acid HA is:
2M(s) + 2HA(aq) → 2MA(aq) + H₂(g)
Have a nice day!

Answer:
Nitrogen gas is filled inside the electric bulb because it doesn't react with the hot filament. Then, it will carry heat away form the filament to cool it.
Answer:
Radiation
Explanation:
Radiation is the transfer of energy in waves. Heat from a campfire is one example.
Hope this is helpful! Have a good day!
Answer:
the protons
Explanation:
the number of protons is constant for each sample of the element. If the number of protons differs, then it is a different element.

Boyle's law :- the pressure (p) of a given quantity of gas varies inversely with its volume (v) at constant temperature.
Boyle's law can also be formularized as P1V1 = P2V2
Charle's law :- the volume occupied by a fixed amount of gas is directly proportional to its absolute temperature, if the pressure remains constant.
Charle's law can also be formularized as V1/T1 = V2/T2
