What subatomic particles participate in chemical bonding
Advocard [28]
The subatomic particle involved in chemical bonding is the electron. Electrons are the smallest of all subatomic particles and orbit the nucleus in discrete energy levels called shells. Electrons are negatively charged and the nucleus is positively charged due to the protons.

yulyashka [42]

Answer:

Your hypothesis is incorrect because warm substances rise when in a colder environment. The correct hypothesis would be : "If the 2 chambers of water are poured side by side, the warmer water will float above the cooler layer because warm water rises and cold water sinks."

Determine the molecular weight of H20.<br> o 18 g<br> O 18.0 g<br> O 18.01 g<br> O 18.016 g
Sonbull [250]

Answer:

The correct answer is D

<u>18.016 g</u>

<u></u>

Explanation:

Molecular Weight : It is the sum of atomic weights of each atoms present in the compound.

The molecular weught is measured in atomic mass.unit( amu) or simply"u"

This is calculated by using :

Molecular weight = number of atom x atomic mass of the atom

For H2O

Number of H atoms = 2

Number of O atom = 1

Molecular weight of H2O = 2(mass of H atom) + 1(mass of O atom)

Molecular weight = 2(1.00784) + 15.999

= 18.01558 u

= 18.016 u
