EnergyThe energy needed to remove an electron from an atom is called
electronegative
valence
ejection
ionization

Answers

Answer:

Ionization energy

Explanation:

Think of it this way: ions are elements with positive or negative charge. If we remove an electron, we give the element a positive charge and it becomes a cation (positive ion). Ionization energy is the energy required to do so - the more electronegative the element, the closer it holds its electrons, the harder they are to remove and the more energy you need.
Ionization energy is your answer I just took the test and passed

Cobalt (Co) has an atomic mass of 59 and an atomic number of 27. Which statement correctly describes an atom of cobalt?A. An atom of cobalt contains more neutrons than protons.
B. An atom of cobalt contains more electrons than protons.
C. An atom of cobalt contains the same number of neutrons and protons.
D. An atom of cobalt contains the same number of neutrons, electrons and protons.

Answers

Answer:

A

Explanation:

27 us the number of protons when we subtract 27 from 59 it will be 32 because a mass number is the sum of proton and neutron but tell u more on the comment

Answer: A - An atom of cobalt contains more neutrons than protons.

Explanation: The atomic number is the number of protons in an atom. The atomic mass is the sum of protons & neutrons in an atom. So, with simple math we can figure out the number of neutrons. Total 59 - 27 protons = 32 neutrons. Which means that A is the only right answer in this case.

Little Extra: A & B would both be correct if Cobalt was a negatively charged ion. An atom is an ion if it is charged, and an ion is either negatively charged or positively charged. For example, if Cobalt had 27 protons & 26 electrons it's overall charge would be positive since it has more protons than electrons. And it would be negatively charged if Cobalt had 27 protons & 28 electrons. No charge if there are 27 protons & 27 electrons because proton +1 and electron -1. Imagine 27-27=0 no charge, 27-26= +1 charge, 27-28= -1 charge

I hope this made you smarter.

An enzyme is a catalyst used by living things to promote and regulate chemical reactions. What is the most likely enzyme for the chemical reaction depicted below? A. Catalyst A
B. Catalyst B
C. Catalyst C
D. Catalyst D

Answers

Answer:

B. Catalyst B

Explanation:

Explanation: Enzymes are complex proteins that have a very specific shape. Just as a key fits a lock and allows it to open, the active site of the enzyme fits the reactants, allowing them to meet at the right orientation to form new chemical bonds. The shape of catalyst B is the best fit to the given reactants and product. The presence of catalysts allows reactions to proceed at much lower energy levels than without, as high-energy collisions between molecules are no longer necessary.

Which best describes the function of a centrifuge?to separate the solute from the solvent
to separate the dissolved part of a solution into layers
to separate a mixture by heating it for a long period of time
to separate the undissolved particles of a mixture into layers

Answers

The correct answer is the last statement. Centrifugation is to separate the undissolved particles of a mixture into layers. It separates a homogeneous mixture by spinning it at high speeds. The precipitate settles at the bottom while the solution is clear.

The correct answer is the last answer choice
