HN03 + S ---->H2SO4+ NO

To identify which element is oxidized and which element is reduced, you must assign __________ numbers to all elements.

The element that increases in oxidation number is ___________ while the element.

that decreases in oxidation number is___________

Answer 1

#1

$\\ \sf\bull\longmapsto 2HNO_3+S\longrightarrow H_2SO_4+2NO$

• H=2
• N=2
• O=6
• S=1

Hence balanced

Part 2

1. Oxidation no
2. reducing agent
3. oxidation agent
