The chemical formula for aluminum flouride is C). AlF3.
Answer:
positively charged nucleons are 24
Explanation:
Given element:
₂₄⁵⁰ Cr
The superscript before the symbol of the atoms is mass number
The subscript before the symbol is the atomic number
Cr is the symbol of the atom
Now,
Atomic number is the number of protons in an atom.
The protons are the positively charged particles in an atom.
For this specie, the positively charged nucleons are 24
Answer:
C. triple point
Explanation:
It is rare for a substance to have a triple point at 1 atm, so you can't measure it if you are limited to 1 atm.
It's easy to measure the melting point and boiling point, because they are the horizontal portions of the curve.
If you are adding heat at a constant rate, you can determine the heats of fusion and vaporization by measuring the times it takes for the substance to completely melt or vaporize.
This equation is balanced because there are 8 atoms of carbon (C), 26 atoms of oxygen (O), and 20 atoms of hydrogen (H) on each side of the equation.
it's 500kg
