The correct answer is option 2, that is, a star.  

Stars die as they consume all the fuel, which permits a star to go through the process of fusion. A star is formed majorly of helium and hydrogen. Once a star uses all the hydrogen, the star begins to die. When a normal-sized star dies, the core eventually cools into a white dwarf, and then into a black dwarf.  

White dwarf refers to a very dense and small star, which is usually of the size of a planet. A white dwarf is produced when a low-mass star has used all its central nuclear fuel and lost its outer enveloping as a planetary nebula.

An atom of fluorine has an atomic number of 9 and an atomic mass of 19. The atom contains
muminat
The number of neutrons is the difference between the mass number and the number of protons. 

You get the element by looking at the atomic number which is the number of protons. In this case, it is 9 and yes, it is F. 

<span>However it is not an atom because it has 10 electrons so you have a fluoride ion F-. </span>

<span>The number of neutrons = 19 - 9 = 10

Therefore, the answer is D.

I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!

lesya [120]

Chemical equation represents a redox reaction :

2Li + MgCl₂ → 2LiCl + Mg

<h3>Further explanation</h3>

The oxidation-reduction reaction or abbreviated as Redox is a chemical reaction in which there is a change in oxidation number

Reaction

2Li + MgCl₂ → 2LiCl + Mg

Oxidation is an increase in oxidation number, while reduction is a decrease in oxidation number.

Oxidation

\tt Li\rightarrow Li^+(0~to~+1)

Reduction

\tt Mg^{+2}\rightarrow Mg(+2~to~0)

How many grams of oxygen are produced when 1.05 moles of hydrogen gas is<br> produced?
vivado [14]

Answer:

1.058337 grams of hydrogen and 2H2 + O2 ==> 2H2O hydrogen peroxide

mols H2 = grams/molar mass

Using the coefficients in the balanced equation, convert mols H2 to mols O2.

Now convert mols O2 to grams. That's grams mols O2 x molar mass O2.

and it could also produce H2O water but no air but it could make other things
