Hello, I see that you are studying Jan Baptist van Helmont, founder of pneumatic chemistry. I assume that you are studying gases and how plants work.
van Helmont, in his experiment studied the theory of how "plants grow while eating soil." Weird right? He put a willow tree in soil, but before doing that, weighted the soil. After 5 years of seeing the same mass of soil, he concluded that plants grew by drinking water.
So the answer would be:
- Plant mass is related to H₂O
- Conclusions partially correct.
This is because stronger intermolecular bonds require more energy to break. As this energy is supplied in the form of heat when boiling, substances with stronger bonds will have a higher boiling point. The order of strength of intermolecular forces is; London dispersion forces < dipole-dipole<span> < </span><span>Hydrogen bonding</span>
The answer is True

The region or the end of water molecule that is partially positive would be where the Hydrogens are. The end that is partially negative, is where the Oxygen is. These partial charges, are because of the large electronegativity differences present between the hydrogens and Oxygen in the molecule. Thus unequal electron distribution or sharing occurs between the atoms in the molecule causing it to be polar and possess the partial charges.
