2. its melting point is 172.2 K
3. its boiling point is 238.6 K
4. it is disinfectant and can kill the bacteria.
5. it is also used in manufacturing of paper, paints and textile industries.
Answer:
From the periodic table: mass of nitrogen = 14 grams. This means that: molar mass of N2 = 2*14 = 28 grams. Now, number of moles can be calculated using the following rule: number of moles = mass / molar mass. Therefore: mass = number of moles * molar mass. mass = 4.25*10^3 * 28.

Answer:
vegetables and salt
Explanation:
The ideal temperature for fermenting vegetables is between 18⁰-22⁰C. Within this range, the bacteria do their best work, giving high levels of lactic acid. The naturally occurring bacteria on fruits and vegetables is called <em>lactobacillus</em><em>.</em><em> </em>These bacteria convert the sugar to lactic acid, which is what gives that characteristic tangy/sour taste.
