Answer:
Pb(NO₂)₂(aq) + 2 LiCl(aq) ⇒ PbCl₂(s) + 2 LiNO₂(aq)
Explanation:
Let's consider the reaction between aqueous lead (II) nitrite and aqueous lithium chloride to form solid lead (II) chloride and aqueous lithium nitrite.
Pb(NO₂)₂(aq) + LiCl(aq) ⇒ PbCl₂(s) + LiNO₂(aq)
This is a double displacement reaction. We will start balancing Cl by multiplying LiCl by 2.
Pb(NO₂)₂(aq) + 2 LiCl(aq) ⇒ PbCl₂(s) + LiNO₂(aq)
Now, we have to balance Li by multiplying LiNO₂ by 2.
Pb(NO₂)₂(aq) + 2 LiCl(aq) ⇒ PbCl₂(s) + 2 LiNO₂(aq)
The equation is now balanced.
Answer:
Bronze is made of the metals copper and tin.
Explanation:
Bronze is stronger than copper as an outcome of combining that metal with tin or different ores. Bronze is more quickly dissolved and is hence more comfortable to cast. It is also harder than pure metal and considerably extra immune to corrosion.
Pure copper is soft and can be formed into wire or pounded into wanted shapes. If the copper is consequently warmed (tempered), it can be performed soft again. Copper and zinc are blended to create brass, and mixed with tin to produce bronze.
Just look at the name, it tells you the longest C chain. Ending with hexane means that the longest carbon chain is 6 C's long.
If we ignore temperature equilibrium (since no data given), then dynamic equilibrium when the rate of evaporation equals the rate of condensation over a finite period of time and under constant temperature.
This is because at *dynamic* equilibrium, evaporation and condensation are both taking place continuously. If the rates are equal, then the mass of vapour and mass of liquid phases do not change, hence equilibrium. Dynamic because changes are still taking place.
