Does a displacement reaction take place in 'magnesium + lead nitrate'? and if so why?
cestrela7 [59]

Answer:

Maybe or maybe not (not sure)

Explanation:

A displacement reaction is a type of reaction where one element is displaced by another from a compound.

In the case of magnesium and lead nitrate, magnesium is more reactive than lead. Therefore, it will displace lead from lead nitrate to form magnesium nitrate and lead.

The reaction can be represented as:

Mg(s) + Pb(NO3)2(aq) → Mg(NO3)2(aq) + Pb(s)


Another answer could be;

A displacement reaction does not take place in 'magnesium + lead nitrate' because magnesium is more reactive than lead.

Charle's Law
Setler [38]

Convert temperature to Kelvin

  • 225°C=498K
  • 127°C=400K

Convert vol to L

  • 400mL=0.4L

Apply Charles law

  • V1T_2=V2T_1
  • 0.4(400)=498V_2
  • 160=498V_2
  • V_2=0.32L=320mL
