When iron reacts with oxygen to form rust, each iron atoma. loses three ions.
c. gains three ions.
b. loses three electrons.
d. gains three electrons.

Answers

Answer 1
Answer:

Iron rust is the oxidation process that affects iron. Iron reacting with oxygen loses three electrons to form rust. Thus, option b is accurate.

What are oxidation and reduction?

Oxidation is the redox process that raises the oxidationnumber by losing the electron of the species and the reduction will decrease the oxidation state by accepting the electrons.

The iron loses its three electrons when reacts with the atmospheric oxygen in rusting and gets oxidized. The metal oxide is produced as a result of the rust.

Therefore, option b. losing threeelectrons to produce rust is correct.

Compare the speed and space of atoms in a solid, liquid and gas.

Answers

Answer:

Decrease order of speed of atoms in solid state, liquid state and gaseous states:  gas > liquid> solid

Decreasing order of space of atoms in solid state, liquid state and gaseous states:  gas > liquid> solid

Explanation:

Solid state : In this state, the particles are closely packed and does not have any space between them. They have least kinetic energy due to restricted movement. This state has a definite shape and volume.

Liquid state :  In this state, particles are present in random and irregular pattern. The particles are closely arranged but they can move from one place to another and thus have higher kinetic energy as compared to solids. This state has a definite volume but does not have a fixed shape.

Gaseous state :  In this state, particles are loosely arranged and have a lot of space between them. They have highest kinetic energy. This state has indefinite volume as well as shape.

Decrease order of speed of atoms in solid state, liquid state and gaseous states:  gas > liquid> solid

Decreasing order of space of atoms in solid state, liquid state and gaseous states:  gas > liquid> solid
Atoms in a solid stay closely together and form this sort of structure in their atoms , a liquids atoms are slightly spread apart and move around more freely than the solid atoms , gas atoms move as far away as possible from each other ( moving around a lot )

If gas particles start colliding with the walls of their metallic container with increase force what is their direct effect

Answers

Answer: The increase in force will directly effect the pressure exerted by the gas that is high pressure of the gas.

Explanation:

The pressure is defined as force applied per unit area.

Pressure=(Force)/(Area)

Pressure\propto Force

If the gas particles colliding with the walls of container with increase in force then the pressure of the gas exerted by the particles of the gas will also get increased.
I believe your answer would be higher gas pressure.

What is the percentage of water to the nearest tenth in this compound? Ba(OH)2 * 8H2O

Answers

mass of water: 8 * 18 g = 144 g
mass of Ba(OH)2 = 171.3 g

total mass: 144 g + 171.3 g =  315.3 g

percentage of water: (144 g / 315.3 g) * 100% = 45.67%

What happens to a water bottle in a freezer and why

Answers

the water well begin to freeze and turn into soild. why? because the temperature of the the freezer is getting the water bottle cold so when that cold temperature hits that that bottle which has liquid in it so you should know that when liquid is into cold air it well so be soild so when you put the water bottle in the freezer it will be soild. 
and also remember gas - liquid - soild gas change to liquid by hot air  and liuid change to soild by clod air 
hoped i helped
