All atoms of the same element have the same ____.

Answers

Answer 1

Answer:

Answer:

The correct answer is protons.

Explanation:

Hello! Let's solve this!

All atoms of the same element have the same number of protons. The isotopes of an element are chemical species that change the number of neutrons but not that of protons.

Then the different atoms of the same element differ in their protons.

The correct answer is protons.

Answer 2

Answer:

All atoms of the same element have the same number of protons.

Protons are subatomic particles that are found within the nucleus of an atom. They have a positive electrical charge, which is equal in magnitude but opposite in sign to the negative charge of electrons. Protons are one of the three main types of particles found in atoms, along with neutrons and electrons.

The number of protons in an atom determines its atomic number and defines the element. For example, an atom with one proton is hydrogen (H), while an atom with six protons is carbon (C).

An unstable nucleus loses the most mass if the nucleus emits(1) an alpha particle (3) a positron
(2) a beta particle (4) a gamma ray

Answers

The correct answer is option 1. An unstable nucleus loses the most mass if the nucleus emits an alpha particle. This type of electromagnetic radiation has the largest mass among the radioactive particles. When this particle is emitted from a nucleus, it loses two protons and two neutrons therefore large amount of mass is lost.

An analysis of an oxide of nitrogen with a molecular weight of 92.02 amu gave 69.57% oxygen and 30.43% nitrogen. What are the empirical and molecular formulas for this nitrogen oxide? Complete and balance the equation for its formation from the elements nitrogen and oxygen.

Answers

The empirical formula is No2 and molecular formula is N2O4

empirical formula calculation

find the moles of each reactant

=% composition/molar mass

molar mass of oxygen=16 g/mol ,while hat of nitrogen= 14 g/mol from periodic table

moles is therefore=

nitrogen= 30.43/14=2.174 moles

oxygen= 69.57/1 6=4.348 moles

find the mole ratio by dividing each moles with smallest number of mole( 2.174)

nitrogen = 2.174/2.174= 1

oxygen = 4.348/2.174=2

The balanced equation for its formation from the element nitrogen and oxygen is as below

N2 +2 O2 → N2O4

therefore the empirical formula= NO2

molecular formula calculation

[NO2] n= 92.02 amu

[(14) + (16x2)]n = 92.02 amu

46n= 92.02

divide both side by 46

n=2

therefore the molecular formula is gotten by multiplying the empirical formula by 2= [NO2]2= N2O4

Amines are derivatives of the ______ molecule.aldehyde

nitric acid

Answers

Amines are derivatives of the ammonia molecule. Ammonia or azane is a compound of nitrogen and hydrogen, it is a colorless gas with a characteristic pungent smell.

Answer: ammonia

Explanation:- Functional groups are specific group of atoms within molecules that are responsible for the characteristic chemical reactions of those molecules.

1. Aldydes have functional group $-O=C-H$ .

Example: Ethanal with molecular formula $CH_3CHO$

2. Amines have functional group $-NH_2$ .

Example: Methylamine with molecular formula $CH_3NH_2$ . they are formed by substituting one hydrogen of ammonia by a R substituent.

3. Ketones have functional group $-C=O$ .

Example: Acetone with molecular formula $CH_3COCH_3$

4. Nitric acid is a inorganic acid with molecular formula $HNO_3$ .

Examine the graph below.Choose which of the following is NOT true.

Absolute zero on Kelvin scale is -273°C.
Liquefaction of the gas occurs at approximately -155°C.
Condensation occurs at 0°C.
The gas follows a linear relationship between volume and temperature.

Answers

Answer : The incorrect option is, Condensation occurs at $0^oC$ .

Explanation :

Absolute zero on Kelvin scale is $-273^oC$ .

This statement is correct because at $0K$ the temperature in degree Celsius will be, $0K=0-273=-273^oC$

Liquefaction of the gas occurs at approximately $-155^oC$ .

This statement is correct. From the given graph the liquification of gas occurs at $-155^oC$ .

The gas follows a linear relationship between volume and temperature.

This statement is correct. According to the Charles law, the volume of gas is directly proportional to the temperature of the gas. So, gas follow the linear relationship between the volume and temperature.

Condensation occurs at $0^oC$ .

This statement is incorrect because condensation occurs at $100^oC$ . and the condensation is a process in which the phase changes from the gaseous state to liquid state at constant temperature.

As we know that condensation is a reverse process of vaporization. Both the process occurs at constant temperature $100^oC$ .

Hence, the incorrect option is, Condensation occurs at $0^oC$ .

Obviously from the graph, the relationship is linear. Charle's laws also say that so that one can be eliminated. Also using the points on the graph, abolute 0 is -273 and liquefication occurs around -155. That sets the answer to Condensation occurs at 0
