The net ionic equation for the neutralization reaction involving equal molar amount amount of HNo3 and KoH is
H^+ + OH^- = H2O (l)
explanation
write the chemical equation
HNO3 (aq) + KOH(aq) = KNO3(aq) +H2O (l)
ionic eequation
H^+(aq) + NO3^- (aq) + K^+9aq) OH^-(aq) = K^+ (aq) + NO3^-(aq) + H2O(l)
cancel the spectator ions( ions which does not take place in equation ) for this case is NO3^- and No3^-
thus the net ionic is
H^+(aq) + OH^- (aq) = H2O(l)
That is false. mass is converted into energy
Representative elements are also known as Group A elements.
Explanation:
It is known that molecular formula of potassium dichromate is
. As potassium has an oxidation state of +1 and an oxygen atom has an oxidation state of -2.
Let the oxidation state of chromium is x. Therefore, calculate the oxidation state of chromium as follows.
= 0 (as the molecule is neutral)
= 0
2 + 2x - 14 = 0
x = +6
Thus, we can conclude that the oxidation state of the chromium in the potassium dichromate molecule is +6.
