The statement that is not true in the list of options is that an atom that is obeying the octet rule will loose electrons. An atom that is obeying the octet rule will neither loose nor gain electrons.

According to the octet rule, an atom is stable when it has eight electrons in its outermost shell. We must note that stability of atoms is the driving force for all chemical reactions.

Hence, the statement that is not true in the list of options is that an atom that is obeying the octet rule will loose electrons.

Answer:

moles = mass divided by molar mass

Molar mass of Nitrogen gas (N2) = 14*2 = 28 g/mol

Mass of Nitrogen gas = 5g

Moles = 5/28

Moles = 0.18 (rounded)

Ammonia gas will diffuse faster than hydrogen chloride gas because the relative molecular mass of ammonia is smaller than that of hydrogen chloride.

According to Graham's law, the diffusion rate of gases is inversely proportional to the square root of their molecular weights.

Thus, the lower the molecular weight of a gas, the faster it will diffuse.

The molecular weight of ammonia is 17 while that of hydrogen chloride is 36.5. Thus, ammonia will diffuse faster than hydrogen chloride.

Answer:

13.9atm

Explanation:

Use Boyle's Law: P1V1 = P2V2

Manipulate the equation: P2 = P1V1/V2

Substitute the values: P2 = (1.31atm)(5.51L)/0.520L

P2 = 13.88096atm

Explanation:

The sound was repeated because of the phenomenon of echo. The speed of sound in the metal is 800 m/s.

Echo results from the reflection of sound waves. The reason why a sound may be heard twice owes to the phenomenon of reflection which leads to echo.

To determine the speed of sound in the metal;

Length of metal = 1000 m

Time taken between the two sounds = 2.5 s

Using the formula;

V = 2d/t

V = 2(1000)/2.5

V = 800 m/s

H2O is a covalent compound and is called a universal solvent because it dissolves most substances than any other known liquid

The universal solvent, H₂O, is a covalent molecule that dissolves more compounds than any other liquid.

Water makes an excellent solvent because of its physical and chemical composition. In water molecules, hydrogen and oxygen atoms are organized polarly, with hydrogen possessing a positive electric charges and oxide having a negative electrical charge.

Water is referred to be the "universal solvent" because it has a wider range of dissolving abilities than any other liquid. Every living thing on the world requires this. It indicates that wherever water flows, whether through the air, the ground, or our bodies, it carries valuable molecules, minerals, and nutrients.

Explanation:

Answer:

Water is a polar covalent compound since it has Oxygen and Hydrogen which are 2 non-metals and the atoms have an unequal distribution of charge.  Oxygen has δ- since it is more electronegative and Hydrogen has δ+. The shape of the water molecule is not symmetrical and dipoles are cancelled out making it a polar covalent compound.

How many grams would 0 .50 moles of Mg be?

Mg has  an atomic weight of 24 so 1 mole of Mg weighs 24 gms

0.50 moles weigh 0.50 X24gm = 12 gm                

5.

10 moles of Al = ? atoms

1 mole = 6.02 X10^23 atoms ...Avogadros number

10 moles is 10 X6.02X10^23 = 6.02X10^24

6.

Answer:

Ernest Rutherford's atomic models the basis of our understanding of atoms. The model describes the atom as a tiny and dense with a positively charged core called a nucleus with neutral subatomic particles called neutrons. The model includes negative-charged subatomic particles called electrons that orbit the nucleus.

Ernest Rutherford and his fellow scientist created an experiment in which they bombarded very thin sheets of gold foil with fast moving alpha particles. Alpha particles are a type of radioactive particles that are positively charged. During their time, the current atomic model showed that an atom’s mass and charge are uniformly distributed throughout the atom. Using that model, they expected that the alpha particles would pass through the gold foil with slight deflection or even none at all. While the experiment did show that they were undeflected, they were surprised to see that a small amount bounced of the the foil a large angles.

This experiment led Rutherford to conclude that the particles that were highly deflected must have experienced powerful enough force within the atom to be deflected. He concluded that all of the positive charges and the majority of the mass of the atom must be condensed in a very small space in the atom’s interior, which he called the nucleus.  In the nuclear model, the proton and  neutrons are in the nucleus, the center of the atom. Electrons a distributed throughout the atom, orbiting the nucleus.
