Distillation is a process of separating the component substances from a liquid mixture by selective evaporation and condensation.
Answer:
kcl and pb(ch3coo)2
The precipitate is PbCl2
Explanation:
Let us take the options provided one after the other;
In the first case, we have;
LiBr(aq) + NH4NO3(aq) ----> LiNO3(aq) + NH4Br(aq)
You can see that no precipitate is formed here.
In the second case;
2KCl(aq) + Pb(CH3COO)2(aq) ----> PbCl2(s) + 2CH3COOK(aq)
The precipitate here is PbCl2.
Answer:
being stationary relative to a particular frame of reference or another object; when the position of a body with respect to its surroundings does not change with time it is said to be at rest
Explanation:
Answer:
So you should go and try to divide or smth or multiply
The amount of heat a 30-gram sample of substance Y absorbs to melt at its melting point is <u> 105 J.</u>
The enthalpy of fusion of a substance additionally referred to as heat of fusion is the alternate in its enthalpy resulting from imparting electricity, usually heat, to a specific amount of the substance to change its state from a stable to a liquid, at a steady strain.
The heat of fusion is the amount of heat vital to alternate 1 g of a stable to a liquid without a temperature exchange.
The heat of fusion is the strength wished for one gram of a solid to melt without any change in temperature. The heat of vaporization is the energy needed for one gram of a liquid to vaporize (boil) without a trade-in strain.
q = m·ΔHf
= 30 × 3.5
heat <u>= 105 J</u>
