Answer:

You'll have to record the observations in appropriate ways and organize them The way you collect your data should relate to how you're planning to analyze and use it These might for instance include entering numerical observations into a  Qualitative data are collected as descriptions anecdotes opinions quote

1.00L of a gas at STP is compressed to 473 ml. What is the new pressure of the gas?
I am Lyosha [343]
P₁V₁ = P₂V₂

Convert 473ml > LP = \frac{(1ATM)(1.00L)}{(0.473L)}

(1atm)(1.00L) = (0.473L)P₂

Divide by (0.473L)

P = \frac{(1atm)(1.00L)}{(0.473L)}

Solve for 2.11atm

According to VSEPR theory, if there are three electron domains in the valence shell of an atom, they will be arranged in a(n) __
wolverine [178]

Answer:  B. trigonal planar

Explanation:

Valence Shell Electron Pair Repulsion Theory (VSEPR) is a model to predict the geometry of the atoms making up a molecule where atoms are arranged such that the forces of repulsion are minimum.

If a central atom is bound to three electron domains ,the number of electron pairs is 3, that means the hybridization will be sp^2 and the electronic geometry of the molecule will be trigonal planar as the electron pairs will repel each other and attain a position which is most stable.

Example: BCl_3 with 3 electron domains has trigonal planar geometry.

For which of the following elements is the number of neutrons correctly represented, based on the atomic number and mass number
Helga [31]

Answer: A. iron: atomic number 26, mass 56, neutrons 30

Explanation:

Atomic number = proton = 26

Mass number = 56

Mass number = proton + Neutron

56 = 26 + Neutron

Neutron = 56 - 26

Neutron = 30
