P₁V₁ = P₂V₂
Convert 473ml > L

(1atm)(1.00L) = (0.473L)P₂
Divide by (0.473L)

Solve for 2.11atm
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
Explanation:
It lowers the melting point
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
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:
with 3 electron domains has trigonal planar geometry.
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
