2024年5月22日 · HNO3 + KOH ----> KNO3 + H2O. This is the complete equation. this is the net ionic equation. Because it is a strong acid (HNO3) and a strong base (KOH) it will always be

2024年6月1日 · HNO3 is a strong acid and dissociates completely in water so a 5 M solution of HNO3 would have a concentration of hydrogen ions of 5M also. So, pH = -log10[5] = -0.699 which indicates an extremely ...

2016年2月11日 · By the method of half-equations: calcium metal is oxidized, and nitrogen is reduced. Oxidation: Ca(s) rarr Ca^(2+) + 2e^- (i) Reduction: 2HNO_3(aq) +4e^(-) +4H^(+) rarr N_2O_3 +3H_2O (ii) Note that dinitrogen trioxide is a metastable species, and is a mixed valence oxide of N(II+) and N(IV+), hence an average oxidation state of III+. Both (i) and (ii) are balanced with respect to mass and ...

2018年4月14日 · A) if you have 0.55 moles of HNO3 how many oxygen atoms would you have? B) If 0.365g of NaOH is reacted with an excess of HNO3 what is the maximum mass of NaNO3 which could be recovered? C) 12.05cm3 of a 0.2065 M aqueous NaOH solution is titrated to the end-point by 25.05 cm3 of HNO3 solution. What is the concentration of the HNO3?

2024年11月21日 · To balance the chemical equation Li2O + HNO3 → LiNO3 + H2O, first count the number of atoms for each element on both sides of the equation. Start by balancing the atoms that appear in only one ...

2016年1月27日 · By a redox reaction. Sulfur is oxidized to sulfate; nitrate is reduced to nitric oxide: #S(s) + 6NO_3^(-) + 4H^+ rarr 6NO_2(g)uarr + 2H_2O(l) + SO_4^(2-)#

2024年5月23日 · The chemical reaction between nitric acid (HNO3) and sodium carbonate (Na2CO3) is: 2 HNO3 + Na2CO3 → 2 NaNO3 + H2O + CO2. In this reaction, nitric acid reacts with sodium carbonate to produce ...

2015年5月3日 · Start by writing the balanced chemical equation for this reaction. #color(red)(3)NO_(2(g)) + H_2O_((l)) -> color(blue)(2)HNO_(3(aq)) + NO_((g))#

2024年5月31日 · The acid-base reaction between nitric acid (HNO3) and sodium hydroxide (NaOH) produces sodium nitrate (NaNO3) and water (H2O). The balanced chemical equation for this reaction is: HNO3 + NaOH → ...

HNO3 + H2O -> H3O + NO3 is very acidic. This is because HNO3 is a strong acid and almost completely dissociates in water
