Write the dissociation equation for, and give the proper concentrations for a 0.25M K2SO4 solution

concentration of  = 0.50 M

concentration of   = 0.25 M

Explanation:

The dissociation equation of is:

According to stoichiometry:

1 mole of gives 2 moles of

Thus 0.25 moles of gives = moles of

Similarly,

1 mole of gives = 1 mole of

Thus 0.25 moles of gives = moles of

Thus the concentration of and are 0.50 M and 0.25 M respectively.

the pseudoscience are like beliefs, theories, or like practices that are considered scientific

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
