Answer : The balanced oxidation-reduction reaction is,

2HNO_3+S\rightarrow 2NO+H_2SO_4

In this reaction, the 'S' atom shows oxidation and 'N' atom of HNO_3 shows reduction.

Explanation:

Redox reaction : It is a type of reaction in which an oxidation and reduction reaction takes palace simultaneously.

Oxidation : The loss of electrons and gain of oxygen or increase in the oxidation number is an oxidation.

Reduction : The gain of electrons and loss of oxygen or decrease in the oxidation number is a reduction.

The balanced redox reaction will be,

2HNO_3+S\rightarrow 2NO+H_2SO_4

From this we conclude that, the 'S' atom is oxidized due to increase in the oxidation number from 0 to (+6) and 'N' atom of HNO_3 is reduced due to decrease in the oxidation number from (+5) to (+2).  So, 'S' atom shows oxidation and 'N' atom shows reduction.

What is the mass of oxygen in 300 grams of carbonic acid (H2CO3)
DENIUS [597]

mass of carbonic acid = 300g

molar mass of H2CO3 = 2H + C + 3 O

= 2 x 1.008+ 12.01 + 3 x  16

= 62.03g/mol


moles of H2CO3 = mass/Molar mass

= 300/62.03

= 4.8364 moles


1 mole H2CO3 has 3 moles Oxygen


4.8364 moles H2CO3 contains  

=   3 x 4.8364  moles Oxygen  =   14.509 moles Oxygen


moles = mass/Molar mass


mass of oxygen = moles x Molar mass of Oxygen

= 14.509 x 16

= 232.15g Oxygen

mass of oxygen in 300g of carbonic acid(H2CO3) = 232.15g

How many grams of CrSO3 are in 2.4 moles of CrSO3
castortr0y [4]

Answer: 316.8 g CrSO3

Explanation: Solution:

2.4 moles CrSO3 x 132 g CrSO3 / 1 mole CrSO3 = 316.8 g CrSO4

The conversion factor is 1 mole of CrSO4 is equal to its molar mass which is 132 g CrSO3
