It is harmful because you can get burned easy and your clothes can get dirty.
Answer:
B. Lower than 100 °C because hydrogen sulfide has dipole-dipole interactions instead of hydrogen bonding.
Explanation:
Boiling point is a physical property which is usually a product of breaking intermolecular bonds.
Both dipole-dipole attractions are intermolecular bonds and they have serious effect on boiling point of a substance.
Hydrogen bonds are very strong intermolecular bonds compared to dipole-dipole attractions. In hydrogen bonding hydrogen atom is directly joined to a highly electronegative atom.
Dipole-Dipole attraction exists between molcules that are polar. Such molecules line up such that the positive pole of one molecule attracts the negative pole of another.
Hydrogen bonds in water are much stronger than the dipole-dipole attraction of hydrogen sulfide.
Answer:
A
Explanation:
Two specialized cells called 'guard cells' make up each stoma (stoma is singular for stomata). Plants have many stomata up to 400 per mm2 on their leaf surfaces and they are usually on the lower surface to minimize water loss.
Answer:
1-Butene
Explanation:
In the final reaction, the 
will<u> oxidize</u> the previous molecule to obtain the <u>butanoic acid</u>, therefore the previous molecule has to be <u>primary alcohol</u>: 1-Butanol. The 
/
reaction can produce <u>antimarkonikov alcohols</u> therefore the initial molecule has to be an <u>alkene</u>: the 1-Butene.

Group 6, sulfur, selenium and polonium.
Valence -2
This group also has valences 4 and 6.
This group also includes oxygen and tellurium.
