Please answer. I’ll give Brainliest if correct. I’m lost. Read the chemical equation shown.

2Ag + H2S → Ag2S + H2

Which statement is true about this chemical equation? (5 points)

Ag (silver) is oxidized and H (hydrogen) is reduced.

Ag (silver) is reduced and H (hydrogen) is oxidized.

S (sulfur) is reduced and H (hydrogen) is oxidized.

S (sulfur) is oxidized and Ag (silver) is reduced.

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :
