Balance the following reactions under Basic
conditions to find how many mols of H2O are in the
balanced equation.
a) CrO(s) + ClO-1 (aq) ➔ CrO4-2
(aq) + Cl-1 (aq)
b) H2O2(l) + ClO2(aq) ➔
ClO2- (aq) + O2(g)
c) ClO2(aq) ➔ ClO3-(aq) +
Cl-1(aq)
d) Ca(s) + H2O(l) ➔ Ca(OH)2(aq) +
H2(g)
e) Fe(OH)3(s) + OCl-1(aq) ➔
FeO4-2(aq) + Cl-1(aq)
Thank you!
‼️Pls show all steps in simple terms to learn it.
℞Acetaminophen250 mg
Phenylephrine hydrochloride15 mg
Clophedianol HCl25 mg
Thonzylamine HCl40 mg
1.How many milligrams each of chlopedianol HCl and
thonzylamine HCl are required to dispense this prescription? Round
each answer to the nearest ten milligrams. (0.5)
2.The pharmacist decides to use acetaminophen tablets to
compound this prescription. How many 325-mg acetaminophen tablets
would be needed from the stock container? (0.5)
Balance this reaction, show all steps? (Answer given)
AsO3 (-3) + MnO4 (-1) ----> AsO4 (-3) + Mn (2+)
Answer:
5AsO3 + 2MnO4 + 6H+ ---> 5AsO4 + 2Mn + 3H2O
Please show the steps in between like the half reactions and
balancing them. Thanks
How to balance redox reactions in acid?
a. Br2 + NO2^- ---> Br^- + NO3^-
b. H2O2 + Cr^+3 ---> Cr2O7^-2 + H2O
c. Cr2O7^-2 + CH3OH ---> Cr+3 + CH3COOH
d. NO2^- + I^- --> N2 + I2
I believe a. is NO2^-1 + H2O + 2Br2 --> 2Br^- + NO3^- + 2H+ but
am very confused about the rest
H2SO4 + Mg
Can someone show the steps in solving that REDOX reaction?
Need to show balanced reaction, Complete Ionic equation
and the Half Ionic. What is the purpose of showing the half
Ionic? When solving Redox reactions do you always
need to show the half reactions? thanks much
Balance each of the following redox reactions occurring in basic
solution.
Express your answer as a chemical equation. Identify all
of the phases in your answer.
H2O2(aq)+ClO2(aq)?ClO?2(aq)+O2(g)
Al(s)+MnO?4(aq)?MnO2(s)+Al(OH)?4(aq)
Cl2(g)?Cl?(aq)+ClO?(aq)
Balance the following,
in basic solution, by the method of half reactions.
C2H5OH +MnO4-
-->C2H3O2-
+MnO2,
What is the
coefficient on water (H2O) in the product of the
balanced equation?
(a) Balance the following half-reactions by the ion-electron
half-reaction method:
(i) (acid solution) NO3 – (aq) → N2O (g)
(ii) (acid solution) FeO4 2– (aq) → Fe3+ (aq)
(iii) (base solution) Fe2O3 (s) → Fe(OH)2 (s)
(iv) (base solution) Cu2O (s) → Cu(OH)2 (s)
(b) Which of the above equations are oxidation
half-reactions?
(c) Give the formulas of the reactants that become oxidized in
the course of the reaction.
