Answer:
9g
Explanation:
moles O2 = mass / Mr = 12 / 2(16.0) = 0.375
ratio O2 : NO = 5:4
moles NO produced = 0.375 * 4/5 = 0.3
mass NO = Mr * mol = (14.0+16.0) * 0.3 = 9g
Answer:
3 moles of oxygen at STP will occupy a volume of 3×22. 4=67. 2 L.

Answer:
Types of chemical weathering
1. Hydrolysis
2. Oxidation
3. Carbonation
4. Acid rain
5. Acids produced by lichens
Explanation:
Chemical weathering occurs when rocks undergo chemical reactions to form new minerals.
Hydrolysis : is when water dissolves minerals present in rocks forming new compounds.
Oxidation : is when oxygen reacts with rocks eg. rust formation
Carbonation : it uses an acid known as carbonic acid, it is important in the formation of many caves and sinkholes.
