4th phrase
substances in equal amounts in the body
Well, which one of the choices is different? Freezing, solidifying, and condensing mean that the substance is getting colder. With melting, heat is being added to the substance meaning it is changing to a less condensed state of matter. The answer is melting.
Answer:
1) 157 Neutrons, 2) the decimal is simply is due to isotopes, because the elements atomic mass is an average of these isotopes multiplied by its abundance(or percentage on earth.) For Mercury, it has many isotopes(an element with a different mass number, logically the atomic mass listed on the periodic table as a mass has 100% abundance, therefore this is used to find the most abundant mass for that particular element/molar mass) likewise, Mercury has an atomic mass of 200.59 u, as one mol of Hg(mercury) is 200.59 grams.
Explanation:
The formula for Neutrons in an atom of an element is calculated by finding the
Answer:
Filtration is a method for separating an insoluble solid from a liquid. When a mixture of sand and water is filtered: the sand stays behind in the filter paper (it becomes the residue ) the water passes through the filter paper (it becomes the filtrate )
Explanation:
An isotope only differs in the number of neutrons it has. All isotopes of an element <span>have the </span>same<span> atomic number (the number of electrons/protons), therefore, they have the </span>same<span> number of electrons/protons and therefore similiar chemical properties.</span>
