Answer:
10. it increases the boiling point because it is a stone bond and will require much energy to break it.
11.So, to boil liquid water, all hydrogen bonds have to be broken and it requires a large amount of energy. This isn't the case in HF; all hydrogen bonds need not to be broken, and therefore a lesser amount of energy is required. So HF boils at a much lower temperature as compared to water even though F has high electronegativity but the force of attraction or the intermolecular is is weak
Ammonification refers to chemical reactions in which amino groups (NH2) associated with organic forms of nitrogen are converted into ammonia (NH3) or ammonium (NH4+).
I'm not sure it depends if it has any hydroxide ions which in that case it would be alkaline, but if that's the question I'd say tthat the substance is neutral
<span>Burning gas in a Bunsen burner is also a chemical change. The methane gas burns with oxygen in the air to form two new substances: carbon dioxide and water vapour. During this chemical reaction heat is also produced. When you try to light a piece of solid wax it melts, but does not burn.
The answer is A. No gas bubbles form.
