which substance is an oxidizing agent? (NaOH, H2O2, HCl, or NaCl)?

H2O2 hydrogen peroxide`

Sodium Hydroxide (aqueous). It's a solution in water of the compound NaOH.

D) reducing agent\n\nBr2 is neutral,whereas Br- is negatively charged (There has been an addition on of electron).Electron gain is reduction.So Br2 has been reduced.\nHence Sodium bisulfite is a reducing agent.

you have salty chlorine water.\n\nAs long as the pH is not acidic  -pH drops, then chlorine will leave the solution.\n\n------------------\nIf you mean sodium hypochlorite for chlorine water - salt is a normal decomposition product

na+2h2o=na(oh)2 + h2\n1.Note that na is a highly reactive metalk reacts even with cold water producing sodium hydroxide and liberating hydrogen.\n2h2so4+naoh = na(so4)2 +2h2o\nNote that h2so4 (sulphuric acid) reacts with naoh(sodium hydroxide),abase and the reaction b/w acid and base forming water and a salt is called neutralization reaction

STP is 1 atm, 273 K.\n\nmoles of HCl = PV/RT = 1 atm * 1.1 L/ (0.08206 * 273K) = 0.049 moles\n\nSince HCl and NaOH is a 1:1 reaction, 1 mole HCl gives 1 mole NaCl, so you get 0.049 moles NaCl (MW 58.5), or 2.87g.

NaOH ® Na+ + OH- is sodium hydroxide, a common base.\nWater has equal hydronium and hydroxide ion and is thus neutral as is C2H5OCOOH ® H+ + C2H5OCO O- which is in chemical equilibria and C2H5OH is ethanol that might have a slight alkalinity but is not considered a base.

sodium chloride or salt

FIRST OF ALL WHY THE SODIUM CHLORIDE IS HARM FULL TO HUMAN ??BUT THE ANSWER IS WRONG TEE Na Cl react with aluminum to produce hydrogen and sodium aluminum oxide. and a lot of heat. if the aluminum is in the powder form which will produce lot of heat and H2 which will cause a blast. do it your self proof the H2 with adding a balloon to the reacting bottle and let the balloon fly.

Na+ and OH- you are dissolving a salt\n\nby the way, i am getting a phd in chem, so trust me. also, there are tons of answers in there that are totally bullshit.

The elements Hydrogen (H+) and Chlorine (Cl-) to make HCl (aka hydrochloric acid)

NaOH ----------------> Na+   +   OH-\nFind the number of moles of NaOH\nMoles of NaOH = 0.10M * 0.150L = 0.015 moles\nSince the coefficients in fornt of NaOH, Na+ and OH- are all 1, therefore if 0.015 moles of NaOH disssociates, 0.015 moles of Na+ and 0.015 moles of OH- are produced.\n\nSimilarly we will work with HCl\nHCl --------------------> H+      +      Cl-\nMoles of HCL = 0.30M * 0.05L = 0.015 moles\nThis means the 0.015 moles of H+ will be produced\n\nSince H+ and OH- have equal amiunts, they will completely neutralize each other leaving the solution at neutral pH. Since the neutral pH is 7, therefore, the pH of this solution will be 7.

NaOH + HCl ---> NaCl + H20

Sodium and Potassium are correct.  They are extremely reactive with water, forming Hydroxides and releasing Hydrogen gas, which is usually ignited from the exothermic heat of the reaction.\n\n2 Na + 2 H2O -> 2 NaOH + H2\n\n2 K + 2H2O -> 2 KOH + H2

Bleach contains NaCl (table salt), H2O, and NaClO (sodium chlorate).\nIt is the "ClO -" ion in the NaClO that causes things to be bleached and lose its colour.

NaOH is lye. It's used in soap.\nBa(OH)2 is used to clean up toxic acid spills\nNH3 is ammonia, which is used in cleaning products\nMg(OH)2 is another base

They all are !\n\nGive each element in the reaction an oxidation number, then see which ones change. An increase in oxidation number is a loss of electrons (oxidation), while a decrease in oxidation number is a gain of electrons (reduction).\n\nAn oxidising agent causes another substance to be oxidised;  it takes electrons from the other substance, and is therefore, itself, reduced.\n\nFor the first reaction.\n\nreactants\nNH3 :  N = -3,   H  = +1\nO2 :    O = 0\nproducts\nNO2 :  N = +4,  O = -2\nH2O :  H = +1, O = -2\n\nnitrogen has lost electrons; it has been oxidised; it is a reducing agent\n\noxygen has gained electrons; it has been reduced; it is an oxidising agent\n\nhydrogen has been neither oxidised nor reduced
