Concentration is a noun and it refer to the act of gatthering closely or the state of gathering together or condition of collecting things or substances together.
In biochemistry it can mean the measure of the ratio of mass to volume in a solute and ratio of mass to volume of a solvent in a solution.
Answer: By definition, if the atomic number =
7
, then there are 7 protons, 7 electrons, and 8 neutrons!
Explanation:
The atomic number is by definition the number of protons, positively charged particles, contained within the atomic nucleus. So if there are 7 protons, there MUST be 7 electrons, 7 negatively charged particles. Why? Because matter is electrically neutral, and positive and negative particles must be equal.
Electrons have negligible mass; the mass number depends on the number of protons contained within the nucleus, PLUS the number of neutrons. Given that we have 15 N
, there must be 8 neutrons contained within the nucleus. does this help?
Its d but not 100 percent sure
Answer:
Force of repulsion.
By decreasing distance and increasing charge on both objects.
Explanation:
Force of repulsion is present between two negatively charged objects due to their same charge. if both charges are opposite to one another so it exerts force of attraction on one another. If we decrease the distance between two negatively charged objects so they exerts more force of repulsion on one another or by increasing power of charge on both objects also increases force on one another.
Answer:
if a players natural resistance to an unbalanced force is called unbalanced force
