Answer: The average rate of formation of O2 over the same time period is 2.41×10-5 M min-1.
Explanation:
The equation of the reaction is given as:
2H2O2(aq)→ 2H2O(l) + O2(g)
Which implies that;
2 moles of H2O2 will produce 1 mole of O2
If H2O2 disappear at the rate of 1 mol/s, O2 would be formed at the rate of 0.5mol/s
Given the average rate of disappearance of H202 to be 4.82×10-5 M min-1.
Therefore;
O2 would be formed at the rate of;
0.5 ×4.82×10-5 M min-1. = 2.41×10-5 M min-1.
The average rate of formation of O2 over the same time period is 2.41×10-5 M min-1.

YES. Do I get brainliest now?
The correct option is A. Rutherford model of the atom consider an atom to be made up of a central nucleus with electrons orbiting around it. The nucleus is considered to be tiny, heavy and its positively charged while the electrons are negatively charged. The shortcoming of this model is that it was not able to explain how the positive nucleus was not able to attract the negative electrons and pull them inside the nucleus.
The natural substrate of beta glycosidase enzyme is Ganglioside GMI, Lactosylceramide, lactose and glycoprotein.
Inhibitors of beta galactosidase enzyme is 1,4-dithiothreitol, beta marcaptoethanol, 4-chloromercurobenzoic acid and Acid-beta galactosidase.
Explanation:
Beta galactosidase enzyme performs the hydrolysis of beta galactosides into monosaccharides. It acts on aryl, amino, alkyl beta glycosidic linkages also.
The enzyme attacks on the bond formed between organic entity and galactose sugar.
It can act on multiple substrates. Some substrates are :
Ganglioside GMI
Lactosylceramide
Lactose : Enzyme beta galactosidase enzyme is a boon for lactose intolerant people because it breaks lactose in yoghurt, sour cream and cheese and makes it easy for consumption to such people.
glycoprotein : These have glycosidic bonds on which enzyme works to break the bonds.
The inhibitors for the β-galactosidase are :
4-dithiothreitol
beta marcaptoethanol
4-chloromercurobenzoic acid
Acid-beta galactosidase.
When inhibitors are bind to enzyme it breaks down the inhibitor and reaction does not takes place.
