how does the octet rule predict the stability or reactivity of atoms.

Answers

Answer:

Explanation:

The octet rule allows chemists to predict the placement of electrons around the nucleus (electron orbitals), the identification of electrons added or lost during chemical reactions and the chemical reactivity of atoms based upon their particular electron configuration.

What is the force of attraction between two atoms that are combined?

two differences between atom and molecules

Answers

Answer:

Molecules are made of atoms. atoms are smaller. molecules have no electrons, atoms do.

Answer:

well one of the begins with and A while the other one begins with a M, joking so the difference between an atom and a molecules is that, An atom is the smallest unit of matter that retains all of the chemical properties of an element. while Molecules can be described as the smallest particle of an element or a compound, which is capable to exist independently and shows all the properties of the respective substance.

What is the molecular formula of the molecule that has an empirical formula of CH2O and a molar mass of 120.12 g/mol

Answers

Answer:

C4H8O4

Explanation:

Let (CH20)x

C=1*12.01=12.01     (12.01, 1.01, 16.00 Avg mass of elements)

H=2*1.01=2.01

O=1*16.00=16.00

12.01 + 2.01 + 16.00 = 30.03

120.12/30,03=4

==> (CH2O)4 = C4H8O4

The molecular formula of the molecule that has an empirical formula of [tex]CH_2O[/tex] is equal to [tex]C_4H_8O_4[/tex].

Given the following data:

Empirical formula = [tex]CH_2O[/tex]Molar mass = 120.12 g/mol.

Scientific data:

Molar mass of oxygen = 16 g/mol.Molar mass of hydrogen = 1 g/mol.Molar mass of carbon = 12 g/mol.

To determine the molecular formula of the molecule that has an empirical formula of [tex]CH_2O[/tex]:

First of all, we would find the molar mass of [tex]CH_2O[/tex]:

[tex]CH_2O =12 +(1\times2)+16\\\\CH_2O =30\;g/mol[/tex]

For molecular formula:

[tex](CH_2O)n = 120.12\\\\30n = 120.12\\\\n=\frac{120.12}{30}[/tex]

n = 4.0

[tex](CH_2O)_4 = C_4H_8O_4[/tex]

Answers

Isotopes are atoms of the same element that have different numbers of neutrons. Protons are positively-charged particles found in the nucleus of an atom.

Electrons are negatively-charged particles found in the outer shell of an atom. The charge on an element is determined by the number of protons and electrons present in the atom.

a.) Li+:  number of protons = 3

Number of electrons = 2

charge of Li+ = +1

b.) Be2+: number of protons = 4

Number of electrons = 2

charge of Be2+ = 2+

c.) C4+: number of protons = 8

Number of electrons = 4

charge of C4+ = 4+

d.) O2-: number of protons = 8

Number of electrons = 10

charge of O2- = -2

e.) N3-: number of protons = 7

Number of electrons = 10

charge of N3- = -3

f.) C4- : number of protons = 4

Number of electrons = 4

charge of C4- = -4

g.) 14C6: The mass number = 14

Atomic number = 6

Number of neutrons = 8

h.) 18O8:  The mass number = 18

Atomic number = 8

Number of neutrons = 10

i.) 19F9:  The mass number = 19

Atomic number = 9

Number of neutrons = 10

j.) 40Ca20:  The mass number =40

Atomic number = 20

Number of neutrons = 20

k.) 37Cl17:  The mass number = 37

Atomic number = 17

A student uses a magnet to move a 0.25kg metal ball. The magnet exerts a force of 5N on the ball. What is the acceleration of the ball when it begins to move ?

Answers

Answer:

20 m/s²

Explanation:

The acceleration of an object given it's mass and the force acting on it can be found by using the formula

[tex]a = \frac{f}{m} \\ [/tex]

f is the force

m is the mass

From the question we have

[tex]a = \frac{5}{0.25} \\ [/tex]

We have the final answer as

Based on table N of the reference tables what is the number of hours required for 42k (potassium -42) to undergo three half-life periods

Answers

The number of hours required : 37.2 hours

Further explanation

Given

⁴²K (potassium -42)

Required

The number of hours

Solution

The atomic nucleus can experience decay into 2 particles or more due to the instability of its atomic nucleus.  

Usually, radioactive elements have an unstable atomic nucleus.  

Based on Table N(attached), the half-life for ⁴²K is 12.4 hours, which means half of a sample of ⁴²K will decay in 12.4 hours
