Explanation:
There can be two electrons in one orbital maximum. The s sublevel has just one orbital, so can contain 2 electrons max. The p sublevel has 3 orbitals, so can contain 6 electrons max. The d sublevel has 5 orbitals, so can contain 10 electrons max.

First look up the atomic weight of mercury.
atomic weight of mercury = 200.59
Then divide the mass of the mercury you have by it's atomic weight
101 / 200.59 = 0.503515
So you have 0.503515 moles of mercury. Round the result to 3 significant digits giving you 0.504 moles.</span>
Answer:
It should be about 2.017 moles
Explanation:
1 mole of any gas at STP occupies about 22.4 liters, so just divide 45.2/22.4 and you'll get 2.01785714 which you can then round as needed
Remember that the formula for kinetic energy is:
Kinetic energy = 1/2 mv²
KE = 1/2 * 14 kg * (3 m/s)²
KE = 7 kg * 9m²/s²
KE = 63 kg*m/s² * m
KE = 63 N*m
KE = 63 J
The kinetic energy of the bicycle is 63 joules.
Yes h20 can act as an acid or a base depending, if h20 donates a proton it will be a Bronsted lowery acid. If h20 accepts a proton it will be a Bronsted Lowry base. Hope that helps
