Chemistry
1 answer:
Citrus2011 [14]2 years ago
5 0

Answer: options B,D and F

Explanation:

Since redox reactions are those which involves both oxidation and reduction

In B , Cu is oxidized and S gets reduced

D, Na gets oxidized and hydrogen gets reduced

F, carbon gets oxidized and Oxygen gets reduced

In g, there is no change in oxidation no of s in both product and Reactants is same +4

Similarly in the case of Ag and Mg.

How much does 200 gallons of water weigh?
Jlenok [28]
To be able to obtain the mass of the given volume of a substance, we need data on its density since it is the mass per volume of a substance. We multiply this value to the given volume. For water, it is approximately <span>10.02 lb/gal.

Mass of water = 200 gal ( 10.02 lb/gal ) = 200.4 lb

Hope this helped.</span>

Consider this reaction mechanism: Step 1: Mo(CO)6→ Mo(CO)5 + CO Step 2: Mo(CO)5 + P(CH3)3→ Mo(CO)5P(CH3)3 Which of these is an i
Alja [10]

Answer:

Mo(CO)5 is the intermediate in this reaction mechanism.

Explanation:

The reaction mechanism describes the sequence of elementary reactions that must occur to go from reactants to products. Reaction intermediates are formed in one step and then consumed in a later step of the reaction mechanism.

In this reaction mechanism, Mo(CO)5 is the product of 1st reaction and then it is used as a reactant in 2nd reaction. So, Mo(CO)5 is the reaction intermediates.

The overall balanced equation would be,

Mo(CO)6 + P(CH3) ↔ CO + Mo(CO)5 +  P(CH3)3

A small amount wet of hydrogen gas can be prepared by the reaction of zinc with excess hydrochloric acid and trapping the gas pr
dybincka [34]

Answer : The partial pressure of the hydrogen is, 705.9 mmHg

Explanation :

According to the Dalton's law of partial pressure,

P_T=P_{H_2}+P_{H_2O}

where,

P_T = total pressure of the gas = 729.7 mmHg

P_{H_2} = partial pressure of the hydrogen gas = ?

P_{H_2O} = partial pressure of the water = 23.8 mmHg (standard value)

Now put all the given values in the above expression, we get:

729.7mmHg=P_{H_2}+23.8mmHg

P_{H_2}=705.9mmHg

Therefore, the partial pressure of the hydrogen is, 705.9 mmHg
