<span>The mass number of an ion is calculated by adding the neutrons and electrons together. In this case 159+107=266. However, since this ion has a +1 charge, you must add 1 to the electrons. This would give a total mass of 267.</span>
Answer:
Chemical properties
Atomic number. The atomic number indicates the number of protons within the core of an atom.
Atomic mass. The name indicates the mass of an atom, expressed in atomic mass units (AMU).
Electronegativity according to Pauling.
Density.
Melting point.
Boiling point.
Vanderwaal's radius.
Ionic radius.
And many more.
Explanation:
Answer / explanation:
How does concentration affect boiling point of a solvent?
The amount by which the boiling point is raised is directly dependent on the concentration of the solute.
The higher the concentration of a solute, the more it is said to be difficult for the solvent molecules to escape into the gas phase.
However, when a non volatile amount of substance is dissolved in a given solvent, the boiling point of the given solvent increases.
The higher the concentration, the more higher the boiling point of a solvent.
It requires a higher temperature for enough solvent molecules to escape , this the boiling point is raised elevatedly
Im a bit torn here, lets look at the definitions of physical and chemical changes:
physical change changes only the phase/state of a substance, but not what the substance is
chemical change is a chemical reaction where a new substance is formed and energy is given off or absorbed.
(it just started raining and it smells really nice out my window)
clearly, this cannot be just a physical reaction. i think i would be inclined to pick B. but C. could have merit as an answer too. sorry for the ambiguity x
It is going to be <span>Molar Volume
