Answer:
A single distillation cycle is enough to separate the mixture. ... Simple distillation is the method used to separate substances in mixtures with significantly different boiling points, while fractional distillation is used for mixtures containing chemicals with boiling points close to each other.
Explanation:
C, that cells cannot be created nor destroyed.
Cells are produce by other cells. Cells can not be man-made nor destroyed.
Its hybridization would be sp because Be only has 2 covalent bonds with Cl
Answer: C) Tetrahedral
Explanation:
The number of electron pairs is 4 that means the hybridization will be but as there are three bonding domains and one nonbonding domain, thus electronic geometry is tetrahedral and the molecular geometry will be trigonal pyramidal.
Linear electron geometry is possible when number of electron pairs is 2 and the hybridization will be .
Trigonal planar geometry is possible when number of electron pairs is 3 and the hybridization will be .
Trigonal bipyramidal geometry is possible when number of electron pairs is 5 and the hybridization will be .
Octahedral geometry is possible when number of electron pairs is 6 and the hybridization will be .
So multiply number of moles x number of atoms/mole = 1.8066 x 10^24 atoms of H2. One mole of any gas at STP has a volume of 22.4 L. So first determine the number of moles of gas you have.
for example do 7
that 's what I think
