No they don’t each element is unique
The molarity of the Ca(OH)2 solution is calculated as follows
find the concentration of HCl used from the Ph
that is PH = - log H+= 1.3
H+ = 10^-1.3 = 0.05 M
the moles of HCl = molarity x volume/1000
= 0.05 x 300/1000=0.015 moles
write the reaction equation
that is Ca(OH)2 +2HCl=CaCl2 + 2H20
by use of reacting ratio between Ca(OH)2 to HCl (1:2) the moles of Ca(OH)2 is = 0.015 x1/2=7.5 x10^-3 moles
molarity is therefore = moles /volume in liters
= {( 7.5x10^-3) /50} x1000 = 0.15 M ( answer 5)
Answer: 9L
Explanation:
(6 x 300) = 1800 / 200 = 9
Answer:
Chemical bond
Explanation:
Chemical bond is refer to as the interaction existing between two or more atoms, ions or molecules that holds them together by decreasing the potential energy of their electrons. Chemical bond leads to the formation of chemical compounds. Chemical bond may occur as a result of the electrostatic force of attraction that exists between oppositely charged ions such as those in ionic bonds or when electrons are shared such as those in covalent bonds.
