Answers

The characteristics of carbon compounds are they exist with different structures in which the atoms are arranged differently and it forms more compounds than other elements combined.

Explanation:

The carbon atom has atomic number 6 which represents the number of electrons. It is represented by C and it is a non- metal. It has 6 protons, 6 neutrons, and 6 electrons. They are smaller in size so that it can fit in to larger molecules.

It is the only element that can form different compounds because each carbon atoms can form four chemical bonds to other atoms.

The structure of carbon atom is represented with its atomic number 6. The first two electrons are present in inner shell and the remaining four are present in the second shell.

The carbon combines with oxygen, hydrogen, and nitrogen to form many molecules for cellular function. Carbon and hydrogen combine to form hydrocarbon chains and rings.

For example the structural formula for Methane (CH4)

100. mL of a gas are obtained from a reaction at 300.⁰C. What volume will the gas occupy at 100.⁰C?

Answers

Answer:

The new volume is 65.1 mL.

Explanation:

We have,

Initial volume of the gas is 100 mL

Initial temperature is 300 degrees Celsius

It is required to find the volume the gas will occupy at 100 degrees Celsius. Charles law gives the relation between volume and temperature such that,

$V\propto T$

So,

$(V_1)/(V_2)=(T_1)/(T_2)$

V₂ is new volume

$V_2=(V_1T_2)/(T_1)$

V₁ = 100 mL

T₁ = 300 C = 573.15 K

T₂ = 100 C = 373.15 K

Plugging into formula we get :

$V_2=(100* 373.15)/(573.15)\n\nV_2=65.1\ mL$

So, the new volume is 65.1 mL.

Intermolecular distance is the distance between the particles that make up matter. The graph below compares the intermolecular distances in two substances. One substance is gas and the other is a liquid. A bar graph is shown with the title Intermolecular Distance. The y axis title is Distance. The x axis title is Substance. There are two bars on the x axis. One is labeled X and the other is labeled Y. The bar for X is higher than the bar for Y. Which statement best describes the two substances?

Answers

Explanation:

In gases, the molecules are held together by weak Vander waal forces. Due to this they have more kinetic energy and hence, more number of collisions take place between the molecules of a gas.

Therefore, they tend to diffuse at a faster rate and distance traveled by them is more as compared to the distance traveled by the molecules of a liquid.

On the other hand in liquids, the molecules are held by more strong intermolecular forces of attraction as compared to gases but not strong enough as they are in solids. Due to this molecules of a liquid are able to slide past each other. Hence, they have medium kinetic energy.

Therefore, less number of collisions take place between molecules of a liquid as compared to gases.

Thus, we can conclude that particles collide in gas so, substance X is a gas.

X is the gas and Y is the liquid. Intermolecular distances are farther apart in gases than in liquids.

Compared to the charge of a proton, the charge of all electron has(1) a greater magnitude and the same sign
(2) a greater magnitude and the opposite sign
(3) the same magnitude and the same sign
(4) the same magnitude and the opposite sign

Answers

Answer: option (4) the same magnitude and the opposite sign.

Justification:

1) Electrons are negative particles thar are around the nucleus of the atom (in regions called orbitals).

2) Protons are positive particles that are inside the nuclus of the atom.

3) The nucleus of the atom has the same number of protons as electrons are in the orbitals of the atom.

4) The atoms are neutral (neither positive nor negative) because there are the same number of electrons and protons and their charge are of the same magnitude but different sign: (+) + (-) = 0: positive + negative = neutral.

The charge of a proton and the charge of all electron has (4) the same magnitude and the opposite sign

Further explanation

Inside the atom consists of a nucleus containing 3 basic particles namely protons and neutrons, while electrons circulate the nucleus on a particular path so that electrons are not attracted to the nucleus.

The charge of these three atomic particles is based on the Rutherford experiment. Rutherford experimented with firing alpha rays on a thin gold plate. From this experiment it was found that:

1. Most alpha rays are passed through the gold plate, so it is concluded that most of the space in the atom has empty space

2. A small number of alpha particles deflected shows there are positively charged particles inside the atom

(at this time these particles are called protons located in the atomic nucleus)

From here comes the Rutherford atomic model which states that atoms consist of positively charged particles (protons) and negatively charged electrons around the nucleus.

The charge of 1 proton is equal to a charge of 1 electron, but the sign is different.

The proton is positively charged (+1), the electron is negatively charged (-1). and neutrons not charged (neutral)

Charge of 1 electron = e = -1.66.10⁻¹⁹ coulomb

Whereas the neutron charge = 0
