Convert 123 in scientific notation

Answers

✡ Answer: 1.23*10^2 ✡

- - Add a decimal at the end (to the right) and count till you get to the first number.
So now you have 1.23

- - Now you always want to times it by 10 to the power of how many times you moved it over, in this case, 2

Final answer: 1.23*10^2

✡Hope this helps✡

123= 1.23*10^2.

The coefficient should be >=1 and <10.

Hope this helps~

If a person looking at a poster sees green instead of yellow and doesn't see red at all, this person most likely has color blindness where _______ nerves fail to respond to light properly.

Answers

Answer:

The correct answer is red-sensitive nerves.

Explanation:

The individuals with protanopia do not possess the tendency to sense red light, the individuals with tritanopia do not sense blue light, and the individuals with deuteranopia do not sense green light. If an individual is perceiving green color then in that case, the yellow sensitive nerves must function somewhat efficiently as green is an amalgamation of blue and yellow. Thus, the red-sensitive nerves would not be reacting appropriately for this individual.

Umm that's 'cones' a being has rods and cones to distinguish between colors and dark / black light . one would use cones for colored light or colors and rods when its dark .

Arrange the isotopes of sulfur and phosphorus in order of decreasing number of neutrons.Rank the isotopes from most to fewest neutrons. To rank items as equivalent, overlap them.

S-36
P-35
S-32
P-33
P-32
P-31

Answers

Neutrons=mass number-atomic number
most S-36 and P-35(both have 20 neutrons) (36-16=20)(35-15=20)
P-33 (33-15=18neutrons)
P-32 (32-15=17 neutrons)
least S-32 and P-31 (both have 16 neutrons) (32-16=16)(31-15=16)

What is the name of a solution whose concentration of solute is equal to the maximum concentration that is predicted from the solute's solubility?

Answers

A solution whose concentration of solute is equal to the maximum concentration that is predicted from the solute's solubility is called saturated solution.

What is solubility?

Solubility can be defined as a terminology that is used to describe how readily a chemical substance or compound can be dissolved in a solvent to form a solution.

In Science, a chemical substance or compound is said to be soluble if it dissolves completely in a solvent while it is insoluble if it doesn't dissolve or only dissolves partially.

In conclusion, a saturated solution refers to a solution whose concentration of solute is equal to the maximum concentration that is predicted from the solute's solubility.

Answers

To see the number of atoms of an element in a given molecule we need to multiply stoichiometry to the number that is written on the foot of the element that is stoichiometry. Therefore, Much of the mass of an atom is concentrated in its nucleus. The nucleus contains protons and neutrons and the outer part of the atom contains electrons.

What is atom?

Atom is the smallest particle of any element, molecule or compound. Atom can not be further divided. Atoms contains nucleus in its center and electron that revolve around the atom in fixed orbit. Electron has -1 charge while proton has +1 charge. Neutron is neutral.

Much of the mass of an atom is concentrated in its nucleus. The nucleus contains protons and neutrons and the outer part of the atom contains electrons.
