the answer is not finding affordable housing, so that guy was wrong. Just a heads up
In Chemistry, a reactivity series of metals , also known as the activity series refers to the arrangement of metals in the descending order based upon their reactivity .
<u>Salient Features</u> :-
- The metal at the top of the reactivity series are powerful reducing agents since they are easily oxidized.
- The reducing ability of metals grows weaker while traversing down the series.
- The electro-positivity of metals also reduces while moving down the reactivity series.
- Metals that are placed higher on the reactivity series have the ability to displace metals that are placed lower in the series.
<u>The metal reactivity series is given below</u> :-
To access the reactivity of metal , from the given reactivity series identify any of the metal and locate the reactivity based upon the choice of reactivity. The metal at the top (Potassium) is most reactive and the metal at the bottom (Platinum) is the least reactive.

The balanced reaction
is:
AgNO3 + NaCl = NaNO3 + AgCl
<span>We are given the amount of silver nitrate to react with sodium chloride. This
will be our starting point.</span>
15.0 mol AgNO3 (1 mol AgCl / 1
mol AgNO3 ) =15.0 mol AgCl
The amount of moles produced is the same with the amount of the given reactant since they only one is to one ratio.
The can lead to mass wasting
Explanation:
Weathering and erosion can be a bad thing because they can lead or trigger mass wasting.
- Weathering is the physical disintegration and chemical decomposition of rocks to form sediments and soils.
- Erosion is the washing away of weathered materials.
- Mass-wasting is the movement of materials down-slope under gravity.
- Both weathering and erosion can lead to serious problems like mass-wasting because they are earth moving processes.
- Weathering can lead to the formation of sinkholes in an area where rocks are decomposed chemically.
- Erosion can wash away top fertile layer of soil and makes them bare. This can lead to drought.
- Rock fall can be initiated when rocks physically disintegrate.
- Chemical weathering can lead to rust and destruction of structures.
- Undercutting of structures by erosion can lead to the collapse of bridges.
