Answer:

an oxygen atom with 8 electrons, 8 protons, and 9 neutrons

Explanation:

A proton has a positive charge and an electron has a negative charge. Magnitude of both of these charges is same. So, we need the same number of electrons and protons to make the atom neutral.

Neutron is neutral, so we can safely ignore it in this question.

Answer:

an oxygen atom with 8 electrons, 8 protons, and 9 neutrons

Answer:

Density =mass/Volume

First of all let's find the mass

= 2.5 ×102kg

= 225kg

Then the volume

=4.1 × 103 m3

=422.3m3

225kg /422.3m3

=0.53279659

The density of a piece of metal that has a mass of 2.5 × 102 kg and a volume of 4.1 × 103 m3  will be 6.03  kg/m³ .

Density is defined as the ratio of mass of the object to the volume of the object. Different substances have different densities.

The mathematical expression for density is as follows:

Density=Mass/Volume

The mass of a substance is expressed in kilograms and the volume is expressed in liter.

Thus, the unit of density is kg L⁻¹.

The density of a substance does not depend on the amount of the matter.

Thus, density is an intensive property.

To calculate  the density -:

Given,

Mass= 2.5 ×102 kg=2550 kg

Volume=4.1 × 103 m³=422.3m³

Density=mass/volume

Density=2550/422.3

Density=6.03kg/m³

Hence, 6.03kg/m³ is the  density of a piece of metal .

Half-life of C-14 is 5730 years

The age of the bone is the time taken to decay carbon -14 from a mass of 80 g to 0.3125 g. The decay time is 46209 years. That is the age of the bone.

Carbon -14 isotope is radioactive and undergoes nuclear decay by the emission of charged particles. The age of a fossil sample which contains carbon -14 can be determined using the time of decay.

Half life of C-14 = 5730 years

decay constant k = 0.693 / 5730 = 0.00012 yr⁻¹

Initial amount of C-14 = 80 g

final amount = 0.3125 g

Then the time taken to decay 80 g to 0.3125 g is t = 1/k ln (80/0.312)

t = ln (80/0.312) / (0.00012 yr⁻¹)

 = 46209 years.

Therefore, the age of the bone is 46209 years.

Answer:

An element is a material that consists of a single type of atom. Each atom type contains the same number of protons. Chemical bonds link elements together to form more complex molecules called compounds. A compound consists of two or more types of elements held together by covalent or ionic bonds.

Explanation:

Answer:

Acetone is captured and cooled.

Explanation:

The boiling point of acetone is lower than that of water, so it will vaporise before water. Then acetone will be captured and cooled to separate it from its mixture with water.

The statement which is correct about distilling a mixture of acetone and water is as follows:

Thus, the correct option is C.

Distillation may be defined as a procedure that generally involves the conversion of a liquid into a vapor that is eventually condensed back to liquid form. With the help of this process, the separation of components or substances from a liquid mixture by using selective boiling and condensation occurs.

Acetone has the lowest boiling point as compared to water. So, it boils faster than that water and vaporizes before water. After the termination of this process, the acetone will be predominantly captured and cooled to separate it from its mixture with water.

Therefore, the correct option for this question is C.

Answer:

c2h4 (etthane........

bexcuse it has 6 bond of hydrogen

C₂H₄ molecules contains six bonding electrons. Therefore, option A is correct.

Chemical bonding is the process through which two or more atoms, molecules, or ions establish a chemical link to create a chemical compound. The atoms in the resultant molecule are held together by these chemical bonds.

Chemical bonds have three basic characteristics that must be taken into account: their strength, length, and polarity. The distribution of electrical charge among the atoms connected by a bond determines its polarity.

C₂H₄ molecules has six bonding electrons. This molecule is called as Ethylene. When bonding is done between two atoms, each atom shares a pair of electrons with each other.

Hence, for every one bond, two electrons are shared between two atoms

Thus, option A is correct.

To convert from L to ml, we move three spaces to the right and the decimal place moves three places.

Our task here is to convert 600 L to mL. we have to remember that to convert from L to ml, we have to multiply the value in L by 1000

In other words, the value 1000 is known as the conversion factor.

When we do this, we move the decimal place three places to the right to have 600000.00mL

[tex]\boxed {\boxed {\sf 3. \ GAGCTC}}[/tex]

Explanation:

Amino acids are the monomers or building blocks of protein. Proteins are created during protein synthesis according to the genetic information or DNA in an organism.

The DNA is translated to messenger RNA in the nucleus. It travels to the ribosome. There, the mRNA is "read off" in threes. Three nucleotides make up  a codon. Transfer RNA with the corresponding anticodon and an amino acid attaches to the codon and a chain of amino acid forms.

If 3 nucleotides make 1 codon which makes 1 amino acid, then we need double that or 6 nucleotides to make 2 amino acids.

The only answer choice with 6 nucleotides is Choice 3: GAGCTC

Answer:

11.92 Liters O₂(g) at STP

Explanation:

For most stoichiometry problems, if one will convert all given data into moles, solve by rxn ratios, then finish by converting to needed dimensions to complete problem.

2Pb(NO₃)₂ => 2PbO + 4NO₂ + O₂

Given 237.5 grams PbO formed in reaction = 237.5 g/223.2 g/mole = 1.064 mole PbO

From equation ratios, moles O₂ formed = 1/2(moles PbO) = 1/2(1.064 moles O₂) = 0.532 mole O₂

0.532 mole O₂ = 0.532 mole x 22.4  liters/mole at STP = 11.91756272 liters (calculator answer) ≅ 11.92 liters O₂ at STP (4 sig.figs. based on given 237.5g PbO)

K = [N2] [Cl2]³ / [NCl3]²

Explanation:

The equilibrium expression, K, of a reaction:

aA + bB ⇄ cC + dD

Is defined as the ratio between the multiplication of concentrations of products powered to its reaction coefficient and the multiplication of concentrations of reactants powered to its reaction coefficient as follows:

K = [C]^c[D]^d / [A]^a[B]^b

Now, for the reaciton:

2NCl3 ⇄ N2(g) + 3Cl2(g)

K is:

K = [N2] [Cl2]³ / [NCl3]²

Answer:

in most of the endothermic reactions the atoms gains electrons from one to another. since the atom gains electrons there is a electron repulsive force between the host and the guest electron . As stability is inversely proportional to electron repulsive force the atom gains energy to attain stability .
