Explanation:
Dalton’s Atomic Theory
All elements are composed of tiny indivisible particles called atoms.
All atoms of the same element are identical.
Atoms of different elements are different(they have different sizes, masses, chemical properties, etc.).
Atoms of different elements can combine with each other in simple whole number ratios to form compounds. (Law of Definite Proportions).
Chemical reactions occur when atoms are separated, joined, or rearranged. However, atoms of one element are NOT changed into atoms of another element by a chemical reaction. (Law of Conservation of Mass).
Answer:
B.
Explanation:
The neutron/proton ratio for a certain element must fall within a certain range for the element to be stable. That’s why some isotopes of an element are stable and others are radioactive.
Answer:
<h3>The answer is 103.82 moles</h3>
Explanation:
To find the number of moles in a substance given it's number of entities we use the formula
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
We have the final answer as
<h3>103.82 moles</h3>
