Answer:
Molecules can be made of one type of element pr a mixture of element.
Molecule is two or more atoms bonded together.
Compound act like a different substance (because have different properties from its constituent elements).
Explanation:
A molecule is the combination of one or more atoms. These atoms may be from different elements are of the same elements. All the compounds are molecule but not all the molecules are compound. For example,
H₂O is a water molecule and also a compound. H₂ is just a molecule not a compound because both atoms are from same element.
The compound have different properties from its constituent elements. e.g water is compound made up of hydrogen and oxygen. Hydrogen is flammable gas and oxygen support combustion, while water doesn't have these properties. However in mixture elements retain their own properties that's why mixture is different from the compound.
It is defined as that force necessary to provide a mass of one kilogram with an acceleration of one metre per second per second. One newton is equal to a force of 100,000 dynes in the centimetre-gram-second (CGS) system, or a force of about 0.2248 pound in the foot-pound-second (English, or customary) system.
Answer:
B
Explanation:
During cellular respiration in most animals and plants, oxygen reacts with carbon containing molecules (sugars) to provide energy to cells of the organism. the flow of energy in organisms.
