The chemical behavior of an atoms is determine by the formation or destruction of chemical bonds. The chemical bonds are the result of the interaction of the electrons of the atoms. Chemical properties of the atoms are given by how attached are the shell electrons attached to the nucleus and how they interact with other atoms. Chemical changes are the result of exchange valence electrons of the atoms. So, <span>the answer is the atomic particle that determines the chemical behavior of an atom is the electron, because it is the particle that is active in chemical bonding.</span>
Answer:
loose hair, flammable clothing, and all stored chemicals especially flammable liquids., should be kept away from heat.
A fire blanket is a highly flame-resistant blanket that can be used to extinguish a small fire or to wrap around a person in case of a fire and water helps put it out too.
Answer:
a) 6.426 grams of potassium bromide student must weigh.
b) The correct answer is option a.
Explanation:
a) Concentration of potassium bromide = c = 0.180 M
Moles of potassium bromide = n
Volume of the potassium bromide solution = 300 mL = 0.3 L
Mass of 0.054 moles of potassium bromide :
= 
6.426 grams of potassium bromide student must weigh.
b) Drying of flask in drying oven. This is because solution will be prepared by adding water after adding solute. So drying the flask will be not required.
An element is a substance made from only one type of atom (e.g. oxygen is an element made up of only oxygen atoms).
An atom is the simplest form of an element that can exist, such as a lithium atom (Li).
Atoms of different elements can be combined together to create compounds, e.g sodium oxide (Na2O).
A molecule is a combination of 2 or more atoms that form chemical bonds. When these atoms are of the same element, they can be called molecules (e.g. O3 - ozone).
However when a molecule is made up of atoms of different elements, they are classified as compounds (e.g. CO2 - carbon dioxide).
So all compounds are molecules, but not all molecules are compounds.
