Answer:
The answer to your question is: density = 0.5 g/ml
Explanation:
Data
Volume = 10 ml
mass = 5 g
Density = ?
Formula
density = mass / volume
Substitution
density = 5/ 10
density = 0.5 g/ml
Answer:
B
Explanation:
In counting the electron domains around the central atom in VSEPR theory, a Core level electron pair is not included.
Core level electron pair are the electrons other than the electrons in the valency shell of an atom. They in the proximity of the nucleus. They do not participate in the bonding.
VSEPR is the abbreviation for Valence shell Electron Pair repulsion theory. VESPR is a model for predicting molecular geometries based on the reduction in the electrostatic repulsion of the valence electrons of a molecule around a central atom.
Answer:
The mass number tells us the number (the sum of nucleons) of protons and neutrons in the nucleus of an atom.
Explanation:
Explanation:
First of all , there were a total charge of +13e (6 protons from carbon and 7 protons from nitrogen), that meant there requires to be a total charge of +13e after the collision occurred. Listed is 16 protons (+16e), 3 antiprotons (-3e), 8 positrons (+8e) and 16 neutral particles (0e), so the total charge listed is +21e, meaning an excess of +8e, meaning you need 8 electrons (-8e) to balance out the charge.
