which star is the dimmest HELP PLEASE

Answer:

Explanation:

The number of moles of glucose can be found by using the formula

[tex]n = \frac{m}{M} \\ [/tex]

where

n is the number of moles

M is the molar mass

m is the mass of the substance

First we must find the molar mass of glucose

[tex]M(C) = 12 , \: \: \: M( H_2) = 1 \: \: , \: \: M(O_2) = 16 \\ [/tex]

The molar mass of glucose is

[tex]M(C_6H_{12}O_6) = (12 \times 6) + 12 + (16 \times 6) \\ = 72 + 12 + 96 \\ \\ = 180 \: \: g/mol \: \: \: [/tex]

mass = 640 g

So we have

[tex]n = \frac{640}{180} = \frac{64}{18} = \frac{32}{9} \\ = 3.5555..[/tex]

We have the final answer as

Hope this helps you

Answer:

D. All of the above

Fluorite is inorganic solid and can be defined by its chemical formula. Thus option D is correct.

Chemical formula is defined as a chemical elements numbers and symbols are used to provide information about the chemical quantities of atoms that make up a certain chemical compound or molecule.

It is also defined as any of numerous statements of a chemical compound's content or structure.

There are mainly three types of chemical formulas.

Thus, fluorite is inorganic solid and can be defined by its chemical formula. Thus option D is correct.

Answer:

igneous rock

Explanation:

Work completed : 15 J

Work is the transfer of energy caused by the force acting on a moving object  

Work is the product of force with the displacement of objects.  

Can be formulated  

W = F x d  

W = Work, J, Nm  

F = Force, N  

d = distance, m  

Force=F= 5 N

Distance=d=3 m

Work :

Explanation:2gfdxxfgngfnf

Answer:

No

Explanation:

It is not correct to say that an object with the largest volume has the largest mass.

Mass and volume are not directly related. In fact, the relationship between them can be direct or inverse.

Mass is the amount of matter in a substance. Volume is the space a body occupies.

Therefore, it is wrong to say a balloon has more mass because it has more volume.

The independent variable is the variable or the factor in an investigation which is manipulated or change in the experiment and affects the dependent variable and produces a various result.

In this investigation, there are different brands of the floor was are the independent variable as they are changed to see the effect on the scratches on the floor on 20 tiles for each brand.

Answer: The atmosphere of Earth wasn't always full of oxygen. ... An accidental mutation would some day change the world forever as these organisms would become able to feed off of the sunlight around them, and produce oxygen in a process known as photosynthesis. This oxygen, which none of these organisms could use, was toxic.

Answer:

Submilation

Explanation:

The coefficient 3 represents the electron shell

In an atom there are levels of energy in the shell and sub shell  

This energy level is expressed in the form of electron configurations.  

Writing electron configurations starts from the lowest to the highest sub-shell energy level. There are 4 sub-shells in the shell of an atom, namely s, p, d and f. The maximum number of electrons for each sub shell is  

• s: 2 electrons  

• p: 6 electrons  

• d: 10 electrons and  

• f: 14 electrons  

Charging electrons in the sub shell uses the following sequence:  

1s², 2s², 2p⁶, 3s², 3p⁶, 4s², 3d¹⁰, 4p⁶, 5s², 4d¹⁰, 5p⁶, 6s², etc.  

Argon is a noble gas element with the symbol Ar with atomic number 18 and mass number 40

Electron configuration: [Ne] 3s²3p⁶

The coefficient 3 represents the electron shell, which is denoted as the quantum number n

This shell consists of 3 sub shells namely 3s, 3p and 3d which have a maximum of 18 electrons (3s = 2 electrons, 3p = 6 electrons and 3d = 10 electrons)
