What does an atomic number represent in an atom? number of neutrons number of protons number of electrons number of protons and neutrons
Answer:
The number of protons in the nucleus of the atom is equal to the atomic number (Z). The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus.
Answer: I'm pretty sure the answer is Number of Protons

is this how mitosis works?
Please give real answers, brainliest to best
Answer:
Pretty much, yes!
Explanation:
The cell starts like this: o
First, the DNA inside the cell replicates and condenses into chromosomes. The also gathers all the materials necessary to divide and duplicates some organelles. (represented by 0)
Then the chromosomes pair up and are pulled to opposite poles of the cell. Then, the membrane pinches (invaginates) in in preparation to make two cells (8).
Then, cytokinesis occurs, when the cytoplasm splits and two new cells are formed (oo)

Isopropyl alcohol is a liquid with a density of 0.785 g/cm^3. How much volume would be taken up be 50.0 grams of isopropyl alcohol
Answer:
63.94 cm³Explanation:
The volume of a substance when given the density and mass can be found by using the formula
[tex]volume = \frac{mass}{density} \\ [/tex]
From the question we have
[tex]volume = \frac{50}{0.785} \\ = 63.694267...[/tex]
We have the final answer as
63.94 cm³Hope this helps you

When a solid with a mass of 53.78 g is added to 50.0 ml of water in a graduated cylinder, the volume increases to 56.4 ml. Calculate the density of the solid.
Answer:
The answer is 8.40 g/mLExplanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} \\ [/tex]
volume = final volume of water - initial volume of water
volume = 56.4 - 50 = 6.4 mL
We have
[tex]density = \frac{53.78}{6.4} \\ = 8.403125[/tex]
We have the final answer as
8.40 g/mLHope this helps you

Look at the chemical equation below.
2N2 + O2 2N2O
How many Nitrogen molecules are present? ___________
How many Oxygen molecules are present? ___________
How many N2O molecules are present? ___________
The molecules of Nitrogen, oxygen, and N₂O are 2, 1, and 2 respectively.
What is the chemical equation?A chemical equation can be defined as the expression of a chemical reaction in terms of the chemical symbols of the substances. A chemical equation has reactants, formed products, and an arrow indicating the direction of the reaction.
The equation in which the number of atoms of each element is equal on either side of the chemical equation of a reaction is called a balanced chemical equation.
According to the law of mass conservation, the total mass of the elements on the reactant side should be equal to the total mass of elements on the product side.
Given, the chemical equation of the reaction of nitrogen ad oxygen gas can be written as:
2N₂ + O₂ → 2N₂O
The number of molecules of Nitrogen gas is 2 and the molecules of oxygen gas are one and the molecules of N₂O are equal to 2.

When fossil fuels, such as gasoline, are burned, they create smoke. Smoke is best described as a heterogeneous mixture of solid particles from the burning fuel dispersed in a gas – usually air. Smoke can be described more specifically as a suspension. What will most likely happen over time to smoke in the atmosphere? The solid particles will spread out and dissolve. The particles will eventually come together in a cloud and produce rain. Over time, the solid particles will settle on whatever is outside. The particles will remain mixed in the air.
Answer:
Over time, the solid particles will settle on whatever is outside."

Titanium on reaction with chlorine forms Titanium tetra chloride(TiCl4).
Titanium holds strong covalent bond with chlorine in TiCL4
please help this is worth half of my grade! what letter represents the trough of the wave a,b,c,d,e
Hello good afternoon...God bless the answer to your following question is D
because...A crest point on a wave is the maximum value of upward displacement within a cycle. A crest is a point on a surface wave where the displacement of the medium is at a maximum. A trough is the opposite of a crest, so the minimum or lowest point in a cycle.
How did astronomers use technology to identify characteristics of the Crab nebula? technology that detects ultraviolet light found hydrogen in the nebula technology that detects radio waves identified a pulsar at the center of the nebula technology that detects microwaves revealed the behavior of electrons in the nebula technology that detects gamma rays measured the distance of the nebula from Earth
Answer:
technology that detects radio waves identified a pulsar at the center of the nebula
Explanation:
Crab nebula(M1) is a blob-like patch which is supernova remnants as far as Constellation of Taurus is concerned.
It has apparent magnitude of 8.4 and can only be viewed by telescope. The astronomers make use of technology that detects radio waves, which identified a pulsar at the center of the nebula, this pulsar is a magnetized rotating compact star which is known with it's electromagnetic emissions.
Answer:
technology that detects radio waves identified a pulsar at the center of the nebula
Explanation:
lonic bonds tend to form between two atoms with what characteristics?
Answer:Ionic bonds are formed through the exchange of valence electrons between atoms, typically a metal and a nonmetal. The loss or gain of valence electrons allows ions to obey the octet rule and become more stable. Ionic compounds are typically neutral. Therefore, ions combine in ways that neutralize their charges.
Explanation:
Ionic bonds tend to form between two atoms with a high electronegativity difference.
Explanation:
An Ionic bond is defined as a chemical bond in which the complete transfer of electrons occurs from one atom to another.The transfer of electrons occurs from less electronegative atom to highly electronegative atomThe high electronegativity difference between the atomsCompounds with ionic bonds categorized as ionic compoundsSo, from this, we can conclude that ionic bonds tend to form between two atoms with a high electronegativity difference.

4. One of the most common predation relationships that can be seen in the Florida Everglades is between the Florida
Panther and the White Tailed Deer. Since the Florida Panther is an endangered species, what would happen to the
deer population as the panther population decreases in size?
A. The deer population would decrease.
B. The deer population would not be affected.
C. The deer population would increase indefinitely.
D. The deer population would increase and then level off.
Answer:
D
Explanation:
It would be D because it would increse yes in population because the panthers are decreasing and attacking less. But, it would still level off because there are other predators who can kill the white tailed deer. Also the panther who is endangered could still atack even though theres just a few left that does not affect them from attacking. So it would increase but it would still level off.
