Answer : The final temperature will be
Explanation :
In this problem we assumed that heat given by the hot body is equal to the heat taken by the cold body.
where,
= specific heat of ice =
= specific heat of water =
= mass of ice = 15.0 g
= mass of water = 150 g
= final temperature = ?
= initial temperature of ice =
= initial temperature of water =
Now put all the given values in the above formula, we get
Therefore, the final temperature will be
Pb(NO₃)₂(aq) + K₂S(aq) → PbS(s) + 2KNO₃(aq)
Pb⁺(aq) + 2NO₃⁻(aq) + K₂⁺(aq) + S⁻(aq) → PbS(s) + K₂⁺(aq) + 2NO₃⁻(aq)
Pb⁺(aq) + S⁻(aq) → PbS(s)
B: Low Melting Point. if you need me to send you my notes tomorrow
Solids' particles move a lot faster and closer together. Liquids' are more spread apart and move slower. So there is more energy in the solid
