Which of the following best explains why most chemical reactions proceed more quickly when the concentrations of reactants are increased?a. The increased concentration increases the number of collisions between molecules.
b. The products of chemical reactions are more stable at higher concentrations.
c. At higher concentrations, reactant molecules move more quickly.
d. At higher concentrations, product molecules are able to catalyze the reaction.

Answer:

Joseph John Thomson studied the properties and the effects of the cathodic rays. Thomson's experiments involved the passage of electricity through a high-vacuum cathode-ray tube composed by a positive electrode (anode) and a negatively charged cathode. This experiment was crucial to describe the nature of the electric discharge.

Explanation:

Michael Faraday placed two electrodes in water solution and then he observed how electricity forces can separate elements in the solution.  

William Crookes studied the forces that drive electricity phenomena by passing electricity through a gas in a sealed tube (cathode ray tubes).

Wilhelm Roentgen discovered the electromagnetic radiation in the X-ray spectrum

Finally, Ernest Rutherford was an apprentice of JJ Thompson. He designed an experiment involving alpha particles that were emitted by a radioactive element. This experiment showed that atoms have tiny and heavy nucleus.

Answer: Option (C) is the correct answer.

Explanation:

Solid and liquid are the states of matter. Plasma is also a state of matter where a number of electrons move freely around the nucleus of an atom.

Whereas water is a liquid itself and liquid is a state of matter but water is not a state of matter.

Therefore, we can conclude that water is not a state of matter.

 is not a state of matter.

Further Explanation:

Matter:

Anything that acquires space and has mass is termed as matter. It is made up of atoms. These atoms can be bonded so strongly or can be far apart from each other. The states of matter can be classified on the basis of features that are visible or can be felt.

States of matter:

1. Solid

It has a definite shape and volume. These are generally hard and have a regular arrangement of its constituent particles. These can be amorphous or crystalline. The intermolecular forces in the solids are very strong and thus the motion of particles in solid is almost negligible. Rock, wood, sugar, and diamond are examples of solids.

2. Liquid

It has a definite volume but can have the shape of any container in which it is placed. The intermolecular forces in the liquids are weaker than that in solids and thus the motion of particles in liquids is more as compared to solids. These have the property to flow. Water, mercury and bromine are examples of liquids.

3. Gas

It has neither a definite shape nor a definite volume. These are highly compressible and have an irregular or disordered arrangement of its constituent particles. The intermolecular forces in the gases are the weakest and thus the motion of particles in a gas is very high. Oxygen, hydrogen and carbon dioxide are examples of gases.

4. Plasma

It has neither a definite volume nor a definite volume. It is present in ionized gases but its uniqueness differentiates it from gases. Plasma contains free charges that make it conductive. Stars and neon signs are examples of plasma.

So solid, liquid and plasma are the states of matter. But water is an example of liquid and therefore an example of a state of matter. Therefore water is not a state of matter.

Gradpoint answer:  a four-carbon hydrocarbon with a double bond between the second and third carbon atoms

the answer is false cause i tried true first and got it wrong.

Answer:

False

Explanation:

Not all solids have an orderly internal structure, although some do which are called crystalline solids. Some examples are metals and table salt. Solids without a orderly internal structure are called amorphous solids. Examples of this are glass, plastics, and rubber.

The pressure of the gas will become double when its Kelvin temperature becomes its initial value.

Further Explanation:

Ideal gas equation:

Ideal gas is just a theoretical concept and practically no gas can act as ideal. It can be considered as group of random moving particles having perfectly elastic collisions between them.

Ideal gas equation for one mole of gas is mentioned below.

PV = RT                                               …… (1)

Here,

P is the gas pressure.

V is the gas volume.

T is the absolute temperature of gas.

R is the universal gas constant.

Standard conditions refer to state when pressure of gas is 1 atm and its temperature is 273 K.

Consider P’ and T’ to be new pressure and temperature respectively while all other terms in ideal gas equation remains constant. Equation (1) then modifies as follows:

P’V = RT’                                               …… (2)

Since new pressure is doubled, P’ becomes 2P. Equation (2) becomes,

(2P)V = RT’                                            …… (3)

Dividing equation (3) by equation (1), we get:

                                     …… (4)

Solving for T’,

Therefore pressure is doubled when temperature becomes twice its initial value.
