Based on the equations below, which metal is the most active? pb(no3)2 (aq) + ni (s) â ni(no3)2 (aq) + pb (s) pb(no3)2 (aq) + ag
erastova [34]

Answer is: nickel (Ni) is the most active metal.

Chemical reaction 1: Pb(NO₃)₂(aq) + Ni(s) → Ni(NO₃)₂(aq) + Pb(s).

Chemical reaction 2: Pb(NO₃)₂(aq) + Ag(s) → no reaction.

Chemical reaction 3: Cu(NO₃)₂(aq)) + Ni(s) → Ni(NO₃)₂(aq) + Cu(s).

From chemical reactions 1 and 3, we can conclude that nickel is more reactive than lead (Pb) and copper (Cu), because lead is more reactive than silver (Ag), chemical reaction 2, nickel is also more reactive than silver.

In chemical reaction 2, no reaction occurs because silver is less reactive than lead. Lead is higher in activity series of metals and can not be reduced.

Nickel is higher in activity series of metals than lead, copper and silver.

The activity series is a series of metals from highest to lowest reactivity. Metal higher in the reactivity series will displace another.

What do you expect will occur as air masses move over cold locations? Hot locations? How does this movement of air masses affect
Maksim231197 [3]

Answer:

Explanation:

When air masses will move over cold location then bottom layer of air cools and become more dense. Due to its high density it is trapped near the ground then it flow towards the equator.

When it moves over hot location then bottom layer gets hot and lighter. Then it moves towards poles.

It changes the temperature and humidity of the climate. making hoter region coll and cooler region a bit hot.
