What can we use to help us predict the results of reaction when we put metals into competition?
Effectus [21]

The activity series of metals as well as the electrode potential of metals can be used to compare the reactivity of metals.

<h3>What is used in comparing reactivity of metals?</h3>

The reactivity of metals can be compared using their electrode potentials which is a measures of the ability of the metal to donate electrons to another metal.

When comparing the reactivity of metals, the metal with the lesser negative electrode potential will be more reactive than another with a greater negative or positive electrode potential.

Therefore, the activity series of metals as well as the electrode potential of metals can be used to compare the reactivity of metals.

The molarity of a solution of 5.0 g of kcl in 100. ml of solution is ________.
sdas [7]
Molarity is defined as the number of moles of solute in 1 L of solution 
mass fo KCl in the solution is - 5.0 g
number of moles of KCl - 5.0 g/ 74.5 g/mol  = 0.067 mol
number of moles of KCl in 100 mL - 0.067 mol
therefore number of KCl moles in 1 L - 0.067 / 100 mL x 1000 mL = 0.67 M
molarity of KCl is 0.67 M

If you add more molecules but do not change the temperature or the pressure, what will happen to the system?
VladimirAG [237]

Answer:

the volume will increase

Explanation:

The kinetic energy of gas molecules depend upon the temperature . If temperature is increased , the molecules will move faster . When temperature is decreased , they move slower .

Hence when more molecules are added to a gas without changing its temperature , the velocity of gas molecules will remain unchanged .

Since pressure  is also constant , it is volume which will be increased .

It can be explained from universal gas formula as follows

PV = nRT

P , R and T is constant ,

V ∝ n

Volume is proportional to n which depends upon number of molecules .

So volume will increase if number of molecules increases .
