Giant cloud of gas and dust

Nebula

Main sequence star

The largest stars

Red super giant

explosion of star

Supernova

the smallest star

neutron star

The star is unable to generate heat when it runs out of hydrogen in its core leading to its contraction and expansion

Red giant star

are the dense, hot remains of the stars that have already perished

White dwarf

this is said to be the remain of the white dwarf

Black dwarf

matter could be divided into tiny particles until such point where it can no longer be divided anymore

Henry Moseley

Equal sharing or electrons

Nonpolar

Unequal sharing of electrons

Polar

is any natural resources that replaces at the same rate on which the resource is used

Renewable energy source

Is any natural source that forms at a rate that is much lower than the rate that it is consumed.

Non-renewable energy source

Are combustible materials that took million of years to form underneath the earth

Fossil Fuel

is produced by the anaerobic decomposition of organic materials brought about by certain varieties of bacteria

Biogas

is the heat obtained from underneath the earth and carried to the surface as steam

Geothermal energy

is the process of obtaining heat or energy from a large body of water

Hydrothermal energy

are voltaic cells that undergo electrochemical processes to produce electrical energy

Batteries

are usually used for powering homes

alter neurons, affecting brain activity, causing a range of problems from headaches to loss of intellect

Neurotoxins

are fat-soluble, making them difficult to eliminate from the body once ingested

Pesticides

commonly known as preservative.

Formaldehyde

the material is usually heat-resistant and can be liquid or rubber like in texture and inert which causes known human allergies or reactions

colorless, soluble alkali gas that occurs naturally in the environment.

Ammonia

also known as bleach is another alkali disinfectant

Sodium hypochlorite

is a natural by product of plant fermentation and can be produced through the hydration of ethylene

are a family of low-level disinfectants with most quarts being derived from benzalkonium

Quaternary ammonium

is a powder that releases hydrogen peroxide and very concentrated.

Sodium Percarbonate

are one of the important group of ingredients that help make cleaning products better

Builders

are chemicals that help ingredients mixed and gives cleaning products the right thickness, so they are easy to use

cleaning washes away germs with any dirt and soil that is removed

Antibacterial or Disinfecting Ingredients

a surface active agent, capable of reducing the surface tension of liquids

Surfactants

any substance that softens the skin by slowing the evaporation of water

Emollient

it's water-attracting and repelling properties can also help to draw moisture to the skin as well as provide a barrier against it

Cetyl or Stearyl Alcohol
