How do atoms form chemical bonds

Answers

Answer:

Atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. A chemical bond is a force of attraction between atoms or ions. Bonds form when atoms share or transfer valence electrons. In a covalent bond, two atoms share one or more electrons.

a pure substance consists only of one element or one compound. a mixture consists of two or more different substances, not chemically joined together.

Explanation:

At room temperature, one of the molecules is a gas and one is a liquid. Identify which structure is a gas and which is a liquid.

Answers

it starts at the bottom and then it goes up into the air as evaporation and that’s when the air gets cooler so gas is cooler and the liquid would be hotter

Carbon-14, which is present in all living tissue, radioactively decays via a first-order process. A one-gram sample of wood taken from a living tree gives a rate for carbon-14 decay of 13.6 counts per minute. If the half-life for carbon-14 is 5720 years, how old is a wood sample that gives a rate for carbon-14 decay of 7.9 counts per minute?
A. 5.3 x 102 yr.B. 7.6 x 102 yr.C. 1.1 x 103 yr.D. 9.5 x 103 yr.

Answers

The question is incorrect, the correct question is;

Carbon-14, which is present in all living tissue, radioactively decays via a first-order process. A one-gram sample of wood taken from a living tree gives a rate for carbon-14 decay of 13.6 counts per minute. If the half-life for carbon-14 is 5720 years, how old is a wood sample that gives a rate for carbon-14 decay of 11.9 counts per minute?

Answer:

C. 1.1 x 103 yr

Explanation:

A = count rate of the wood sample

Ao= count rate of a living tissue

t1/2= half life of C-14

t = time taken

From;

0.693/t1/2 = 2.303/t log Ao/A

0.693/5720 = 2.303/t log (13.6/11.9)

1.2 * 10^-4 = 2.303/t * 0.05799

1.2 * 10^-4 = 0.1336/t

t = 0.1336/1.2 * 10^-4

t = 1.1 x 103 yr

Nick needs 3.5 moles of sodium fluoride (NaF) for a solution he is mixing in the lab. How many grams of NaF does Nick need to measure out?​

Answers

Answer:

147 g

Explanation:

The number of moles of a substance is the ratio of the mass of the substance and the molar mass of that substance. Mathematically,

  mole = mass of substance/molar mass

In this case, Nick needs 3.5 moles of NaF, the molar mass of NaF is calculated as:

  23 + 19 = 42 g/mol (Note: Na = 23, F = 19)

Hence,

mass of 3.5 mole NaF = mole x molar mass

                              = 3.5 x 42 = 147 g.

Hence, Nick would need to measure out 147 g NaF using a suitable weighing balance.

Explanation:

The term "genotype" can also reference towards the alleles or variations that an individual possesses. The green plant was most likely the most dominant, having a genotype of TT or Tt.

What is genotype?

An organism's genotype is its whole collection of genetic material. The term "genotype" can also reference towards the alleles or variations that an individual possesses in a certain gene or genetic region. The amount of alleles a person can have in a particular gene is determined by the amount of duplicates of each chromosome contained in that species, which is also known as ploidy.

Diploid organisms, such as humans, have two complete sets of chromosomes, implying that each person possesses two alleles for each given gene. When both alleles are identical, the genotype is said to be homozygous. When the alleles were distinct, the genotype is called heterozygous. The green plant was most likely the most dominant, having a genotype of TT or Tt.

Therefore, the green plant was most likely the most dominant, having a genotype of TT or Tt.

How many known elements have atoms, in their ground-state, with valence electrons whose quantum numbers are n = 5 and l = 1?a. 36..
b. 37.
c. 6.
d. 8.

Answers

Answer:

c. 6.

Explanation:

Looking at the description given in the question, the elements involved must belong to the p- block of the periodic table and must be in period 5. They also must possess valence electrons in the 5p- orbital.

Now if we look at the p- block of period 5, the following elements satisfy these  requirements; Sr, In, Sn, Sb, Te and I.

Hence there are six of such elements.

The chemical elements that have atoms, in their ground-state, with valence electrons whose quantum numbers are n = 5 and l = 1 are: C. 6.

What is a valence electron?

A valence electron can be defined as the number of electrons that is present in the outermost shell of an atom.

In Chemistry, valence electrons are primarily used to determine whether an atom or group of chemical elements that are found on the periodic table can bond with others.

Based on electronic configuration, quantum numbers of n = 5 and l = 1 simply represents a 6p orbital and there a total of six (6) chemical elements with this orbital, and these include;

A. electrophile
B. carbocation
C. E1
D. E2

Answers

Answer:

The correct answer is Option C (E1) and Option B (carbocation).

Explanation:

Intramolecular immunity idols are considered as that of the formation mechanism with E1 responses or reactivity. Reactants with E1 were indeed obligations of both parties, meaning that an E1 reaction was conducted thru all the two stages known as ionization but rather deprotonation. Involves the absence of either an aromatic ring, a carbocation has been generated throughout the ionization solution.
