Na2s2o3 (aq) + 2hno3 (aq) →
a. 2nano3 (aq) + h2o (l) + so2 (g) + s (s)
b. h2o (l) + so2 (g) + s (s)
c. 2nano3 (aq) + h2o (l) + s (s)
d. 2nano3 (aq) + h2o (l) + so2 (g)

The correct answer is Option a.

Explanation:

The reaction between sodium thiosulfate and nitric acid produces a number of products. The balanced chemical equation for the reaction of two follows:

By Stoichiometry of the reaction:

1 mole of sodium thiosulfate reacts with 2 moles of nitric acid to produce 2 moles of sodium nitrate, 1 mole of water, 1 moles of sulfur dioxide and 1 mole of solid sulfur.

Hence, the correct answer is Option a.

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.

the answer to this question is 3.
