What is the oxidation state of h in h2 g?
zero- H2 is the elemental form- by definition the ON# is zero
In the reaction Mg(s) plus 2H2O(l) Mg(OH)2(s) plus H2(g) what is the oxidation state of Mg in Mg(s)?
The oxidation state of magnesium in magnesium hydroxide is +2 no matter what reaction you are looking at.
In the reaction Mg(s) plus 2H2O(l)Mg(OH)2(s) plus H2(g) what is the oxidation state of Mg in Mg(OH)2(s)?
The oxidation state of magnesium in magnesium hydroxide is +2 no matter what reaction you are looking at.
In which reaction does the oxidation number of oxygen increase?
Out of these possible answers A) Ba(NO3)2(aq) + K2SO4(aq) -> BaSO4(s) + 2KNO3(aq) B) HCl(aq) + NaOH(aq) -> NaCl(aq) + H2O(l) C) MgO(s) + H2)(l) -> Mg(OH)2(s) D) 2SO2(g) + O2(g) -> 2 SO3(g) E) 2H2O(l) -> 2H2(g) + O2(g)
What is the oxidation half-reaction for 2Mg plus O22MgO?
2Mg(s) + O2(g) ==> 2MgOMg ===> Mg^2+ + 2e- [x2 to balance electrons] = oxidation half reactionO2 + 4e- ===> 2O^2-So, the final oxidation half reaction will be:2Mg(s) ===> 2Mg^2+ + 4e-
What are the oxidation numbers for each atom in the equation H2g plus O2g to H2O l?
In:(H2)g oxidation state: 0 In:(O2)g oxidation state: 0 In:(H2O)l oxidation state: H: +1 and O: -2
In the reaction mg(s) plus 2h2o(i) mg(oh)2(s) plus h2(g) what is the oxidation state of each h in h2(g)?
The answer is 0
What is the oxidation state of h in h2 g?
zero- H2 is the elemental form- by definition the ON# is zero
In the reaction Mg(s) plus 2H2O(I) and 61664 Mg(OH)2(s) plus H2(g) what is the oxidation state of each H in H2(g)?
Simply remember OIL RIG. Oxidation Is Loss (of electron) and Reduction Is Gain (of electron). In the case of MnO4-(aq) + 8H+(aq) + 5e- --> Mn2+(aq) + 4H2O(l) H is the oxidizing agent, because it causes Mn to be oxidized to Mn2+.
In the reaction Mg(s) plus 2H2O(l) Mg(OH)2(s) plus H2(g) what is the oxidation state of Mg in Mg(OH)2(s)?
The oxidation state of magnesium in magnesium hydroxide is +2 no matter what reaction you are looking at.
In the reaction Mg(s) plus 2H2O(l) Mg(OH)2(s) plus H2(g) what is the oxidation state of Mg in Mg(s)?
The oxidation state of magnesium in magnesium hydroxide is +2 no matter what reaction you are looking at.
In the reaction Mg(s) plus 2H2O(l)Mg(OH)2(s) plus H2(g) what is the oxidation state of Mg in Mg(OH)2(s)?
The oxidation state of magnesium in magnesium hydroxide is +2 no matter what reaction you are looking at.
What is the prime factorization of 36g2h2?
36g2h2 = 2*2*3*3*g*g*h*h provided g and h are prime.
What is…Fe + H2SO4 —> Fe2(SO4)3 + H2 Balanced?
2 Fe (s) + 3 H 2SO 4 (aq) → Fe 2(SO 4) 3 (s) + 3 H 2 (g). This is an oxidation-reduction (redox) reaction: 6 H I + 6 e - → 6 H 0 (reduction).
In which reaction does the oxidation number of oxygen increase?
Out of these possible answers A) Ba(NO3)2(aq) + K2SO4(aq) -> BaSO4(s) + 2KNO3(aq) B) HCl(aq) + NaOH(aq) -> NaCl(aq) + H2O(l) C) MgO(s) + H2)(l) -> Mg(OH)2(s) D) 2SO2(g) + O2(g) -> 2 SO3(g) E) 2H2O(l) -> 2H2(g) + O2(g)
Use the reaction below to answer the following question 2 al s 6h2o g 2 al oh 3 3h2 determine the oxidation number of each element in both the reactants and products of this oxidation-reduction reac?
Al starts at 0 oxidation. then becomes Al 3+ O remains -2 on both sides. H starts at 1+ then becomes 0
What is the formula mass of h20?
H: 1 g/mol O: 16 g/mol H x 2 = 2 g/mol O x 1 = 16 g/mol 2 g/mol + 16 g/mol = 18 g/mol
