Similarities and differences between solids liquids and gases
Masteriza [31]

Answer:

Detail is given below.

Explanation:

Similarities:

All are the forms of matter.

Solid, liquid and gases are made up of ions, atoms and molecules.

They have shape and volume.

Molecules in Liquid and solid are closer to each others.

Liquid and gases can flow very easily.

Liquid and solid both can not compressed very easily.

Differences:

Molecule of gases randomly move everywhere and occupy all available space but liquid and solid's molecules are not move as much easier as molecules of gases can.

The density of gases are very low as compared to the liquid and solid.

Gas molecules are at long distance from each other while in liquid and solid they are closer to each other.

The very weak inter molecular forces are present between gas molecules as compared to the liquid and solids.

Solids have definite volume and shape but liquid and gases acquire the shape of container.

In solids molecules are tightly pack and very close to each other while in liquid molecules are not tightly pack like in case of solid.

The densities of solids are also very high as compared to the liquid and gas.

There are very strong inter molecular forces are present between solid molecules.

You heat 3.869 g of a mixture of fe3o4 and feo to form 4.141 g fe2o3. What is the mass of oxygen reacted?
Lostsunrise [7]

The reaction is  

FeO + Fe3O4 + 1/2 O2---> 2Fe2O3

Thus as shown in the balanced equation two moles of Fe2O3 are formed when 0.5 moles of O2 reacted with mixture of FeO and Fe3O4

moles of Fe2O3 = MAss / Molar mass = 4.141 / 159.69 = 0.0259 moles

So moles of O2 needed = 0.5 X 0.0259 = 0.01295

Mass of O2 = moles X molar mass = 0.01295 X 32 = 0.4144 grams

The spectrum of the combined chloro and aqua cobalt complex solutions tells you_______________.
andre [41]

Answer:The purple color is due to a mixture of the pink aqua complex and blue chloro complex and is not due to a new species.

Explanation:

The pink aqua complex of cobalt can be in equilibrium with blue chloro complex of cobalt giving rise to a purple colour. This equilibrium is governed by Le Chaterliers principle. A change in chloride or water concentration could shift the equilibrium towards any of the species causing its colour to become the dominant colour of the solution.

An object weighting 9.6 grams is placed in a graduated cylinder displacing the volume from 10.0mL to 13.2 mL
grigory [225]

The volume of object is 3.2 ml

<h3>Explanation:</h3>

Given:

Mass of the object = M = 9.6 g

Initial volume of liquid: V_1 = 10.0\ ml

Final volume of liquid after displacement: V_2 = 13.2\ ml

Total volume of the displaced object inside a graduating cylinder will be given as difference between the final volume and initial volume of the expanding object.

V = V_2-V_1 = 13.2 -1 0.0 = 3.2\ ml

V = 3.2 ml
