2. Nitrous acid (MAJOR) and Nitric acid (MINOR)
4. NITROUS AND NITRIC OXIDES ARE EXAMPLES OF NEUTRAL OXIDES.
5. The ph of sulphuric acid is acid therefore its pH will range from 1 to 6.9, (Theoretically) depends on its concentration.

Explanation:
Short answers.
1. A synthesis reaction occurs when two or more reactants combine to form a single product. This type of reaction is represented by the general equation: A + B → AB. An example of a synthesis reaction is the combination of sodium (Na) and chlorine (Cl) to produce sodium chloride (NaCl).
2. Ammonia is manufactured industrially by Haber's process. A mixture of dry nitrogen and hydrogen gases in the ratio of 1:3 by volume is compressed to about 200 to 300 atm and passed over iron catalyst at a temperature of about 723 k to 773 k.
3. Two conditions are for chemical reaction:
a) close contact
b) heat
4. Endothermic reactions absorb energy from the surrounding that is in the form of heat. ... On the other hand, an exothermic reaction releases energy into the surrounding of the system.
5. Yellowish green flame.
