Given:
Volume of KOH = 53.0 mL
Concentration of KOH = 0.320 M
Volume of HNO3 = 28.0 mL
Concentration of HNO3 = 0.250 M
Balanced Equation:
KOH + HNO3 ===> KNO3 + H2O
0.320 0.250 0 0
H2O ===> H+ + OH-
Solve for the concentration of OH-
Hydrogen have only one electron and easily form compounds with other elements that is the reason hydrogen is chemically unstable
The answer is false. It is because the electron structure of
the atom is not determined by using the direct observation of using an x-ray
but rather the usage of theoretical modeling and the emission spectra will be useful
in observing.
All elements can be classified as metals, metalloids, or nonmetals
C i think but you should pick it anyway
