Answer:
The mole is the SI unit for amount of a substance.
Explanation:
Just like the dozen and the gross, it is a name that stands for a number. There are therefore 6.02 × 10 23 water molecules in a mole of water molecules.
Answer:
382.5J
Explanation:
<em>Use the formula:</em>
E = mcΔθ or Q = mcΔT
m = 100g
c = 0.45 J/g°C
ΔT or Δθ = 110 - 25 = 85°
<em>Sub in the values:</em>
E = 100 × 0.45 × 85
= 382.5J
Answer:
The correct option is: (D) All of the above
Explanation:
An atomic orbital is the three-dimensional space or region around the nucleus of an atom, where the probability of finding an electron is maximum.
The s-orbitals are the atomic orbitals that have azimuthal quantum number, l = 0. These atomic orbitals have <u>spherical shape and symmetry.</u>
The p-orbitals are the atomic orbitals that have azimuthal quantum number, l = 1. These atomic orbitals have a <u>dumbbell shape.</u>
The atomic orbitals that are closer to the nucleus, have lower energy. Therefore, we can say that the <u>s-orbitals are lower in energy than the p-orbitals.</u>
