You've asked your friends to define the terms "chemistry" and "chemical." With which definitions do you agree? Check all that ap
ply. Check all that apply. A chemical is a substance that has the same composition but different properties wherever it is found. Chemistry is the study of the composition, structure, properties, and reactions of matter. Chemistry is a natural science concerned with the study of life and living organisms, including their structure, function, growth, evolution, distribution, and taxonomy. A chemical is a substance that has the same properties but different composition wherever it is found.
A chemical is a substance that has the same composition and properties wherever it is found
Chemistry is the study of the composition, structure, properties, and reactions of matter
Explanation:
A chemical is made up of one or more chemical compounds that allow it to fulfill a particular function, because a chemical is a substance that has the same composition and properties wherever it is found.
Already Chemistry is a branch of the Natural Sciences that studies the matter, its properties, constitution, transformations and the energy involved in these processes. Matter, and all that composes it, is the main object of study of chemistry.
According to the law of conservation of mass, In a chemical reaction, mass is neither created nor destroyed. In other words, the total mass for the reactants needs to equal the total mass of the products.
<u><em>In photosynthesis the reactants are 6 carbon dioxide, 6 water and sunlight. The mass of these reactants adds to equal the mass of the products, which are 1 glucose and 6 oxygen. </em></u>
<u><em>Cellular respiration on the other hand uses glucose and oxygen gas to produce water, carbon dioxide, and a usable form of energy known as ATP.</em></u>
Cellular respiration is the opposite of photosynthesis, such that the products of photosynthesis are the reactants of cellular respiration. Cellular respiration also obeys the law of conservation of mass.
