Answer:

An atom with a neutral charge has an equal number of protons and electrons.

Explanation:

The three main subatomic particles in the atom are neutrons, protons and electrons.

Protons are positively charged particles, electrons are negatively charged particles while neutrons are not charged particles.

An atom is neutral if the number of protons and electrons are equal. This is the condition for neutrality in the atom.

The number of protons will be the same for all isotopes of Carbon.  Options A and C are correct.

What made an atom?

An atom is made up of central nucleons (positive protons and neutral neutrons) and surrounding negatively charged electrons.

In a neutral atom, the number of electrons and protons is the same because opposite charges neutralize each other.

The number of protons is the same in all isotopes of an element because changing the proton changes the identity of the element.

Therefore, the number of protons will be the same for all isotopes of Carbon.

A gas has a volume of 45.0 mL and a pressure of .98 atm. If the pressure increased to 2.1 atm and the temperature remained the same, what would be the new volume?

Answers

Answer: The new volume is 95.45 mL.

Explanation:

Given: [tex]V_{1}[/tex] = 45.0 mL,         [tex]P_{1}[/tex] = 0.98 atm

[tex]P_{2}[/tex] = 2.1 atm,               [tex]V_{2}[/tex] = ?

According to Boyle's law, at constant temperature the pressure of a gas is inversely proportional to its volume.

Therefore, formula used to calculate the new volume is as follows.

[tex]\frac{P_{1}}{V_{1}} = \frac{P_{2}}{V_{2}}[/tex]

Substitute the values into above formula as follows.

[tex]\frac{P_{1}}{V_{1}} = \frac{P_{2}}{V_{2}}\\\frac{0.98 atm}{45.0 mL} = \frac{2.1 atm}{V_{2}}\\V_{2} = 95.45 mL[/tex]

Thus, we can conclude that the new volume is 95.45 mL.

What is a state function?

Answers

Is a function defined for a system relating several state variables or state quantities that depends only on the current equilibrium thermodynamic state of the system[1] (e.g. gas, liquid, solid, crystal, or emulsion), not the path which the system took to reach its present state. A state function describes the equilibrium state of a system, thus also describing the type of system. For example, a state function could describe an atom or molecule in a gaseous, liquid, or solid form; a heterogeneous or homogeneous mixture; and the amounts of energy required to create such systems or change them into a different equilibrium state.

What is the mass number of an element?

Answers

sum of protons and neutrons
An element's mass number (A) is the sum of the number of protons and the number of neutrons. The small contribution of mass from electrons is disregarded in calculating the mass number.


Together, the number of protons and the number of neutrons determine an element's mass number: mass number = protons + neutrons. If you want to calculate how many neutrons an atom has, you can simply subtract the number of protons, or atomic number, from the mass number.

The atomic mass of an element is the average mass of the atoms of an element measured in atomic mass unit (amu, also known as daltons, D). The atomic mass is a weighted average of all of the isotopes of that element, in which the mass of each isotope is multiplied by the abundance of that particular isotope.

Answer: Least Common Multiplier of a6m, 0.003 moles 0.01elamos

Steps 6m, 0.003 moles

Compute an expression comprised of Factors that appear either in a6m or 0.003 moles

= 0.018elamos

Explanation:

Taking into account the definition of molarity,  0.005 liters of a 6.0 M solution of acetic acid contain 0.0030 moles​.

Definition of molarity

Molar concentration or molarity is a measure of the concentration of a solute in a solution and indicates the number of moles of solute that are dissolved in a given volume.

The molarity of a solution is calculated by dividing the moles of solute by the volume of the solution:

[tex]molarity=\frac{number of moles}{volume} [/tex]

Molarity is expressed in units [tex]\frac{moles}{liters} [/tex].

This case

In this case, you have a 6.0 M solution of acetic acid that contain 0.0030 moles​. Replacing in the definition of molarity:

[tex]0.6\frac{moles}{liters} =\frac{0.0030 moles}{volume} [/tex]

Solving:

0.6 [tex]\frac{moles}{liters} [/tex]× volume= 0.0030 moles

volume= 0.0030 moles ÷0.6 [tex]\frac{moles}{liters} [/tex]

volume=0.005 liters

Finally, 0.005 liters of a 6.0 M solution of acetic acid contain 0.0030 moles​.

Ionic compounds are held together with ionic bonds between ions. The ions are formed when valence electrons are

Answers

Answer: Electrovalent bonds are produced when electrons are transferred from atoms of one element to atoms of another element, producing positive and negative ions. The bond which is formed by the transfer of electrons between the atoms is called electrovalent bond or ionic bond. Electrovalent bonds are only formed between metals and non-metals. Electrovalent bonds are not formed between two non-metals.

In simple words electrovalent bond involves the transference of a certain number of electrons to another dissimilar atom which has a tendency to gain electrons so that both acquire stable inert gas configurations. The electrostatic attraction always tends to decrease the potential energy. Hence, the potential energy of the system is much less than it was before the formation of an ionic bond.

Explanation: An Ionic bond is the bond formed by the complete transfer of valence electron to attain stability.

This type of bonding leads to the formation of two oppositely charged ions – positive ion known as cations and negative ions are known as anions.

The presence of two oppositely charged ions results in a strong attractive force between them. This force is an ionic or electrovalent bond.

Ionic bonds form between atoms with large differences in electronegativity, whereas covalent bonds formed between atoms with smaller differences in electronegativity.

The compound formed by the electrostatic attraction of positive and negative ions is called an ionic compound.

Answer: The statement, chemicals that you begin with found on the left side of the equation, describes reactant and where they are in a chemical equation.

Explanation:

An equation that includes symbolic formulas and represents chemical reaction between the substances initially present forming new substances is called a chemical equation.

For example, [tex]N_{2} + 3H_{2} \rightarrow 2NH_{3}[/tex]

Here, substances [tex]N_{2}[/tex] and [tex]H_{2}[/tex] are the reactants. Reactants in a chemical equation are always present on the left side as these are the chemicals we begin with.

Also here, [tex]NH_{3}[/tex] is the product. Product(s) in a chemical equation are always present on the right side as these are the chemicals we end with.

Thus, we can conclude that the statement, chemicals that you begin with found on the left side of the equation, describes reactant and where they are in a chemical equation.

(iv) Explain which two food colourings contain the dye that is likely to be the most soluble the solvent.

(b) Determine which food colouring contains a dye with R, value closest to 0.67
Show your working.

Answers

Answer:

(ii) 1 dye

(iii) Food coloring F is insoluble in the solvent

(iv) 'E' and 'H'

(b) Food colouring G

Explanation:

Paper chromatography principle is based on the rates of migration of chemicals across a sheet of paper which are different and it consists of a stationary phase such as the water in the paper and a mobile phase such as the solvent resulting in the partitioning of the components of the mixture across the paper

The solution components are positioned to start in one place from where they migrate and separate out on the chromatography paper

(ii) The number of components into which the food colouring 'H' separates into = 1

Therefore, the number of dyes in food colouring 'H' = 1 dye

(iii) Food coloring 'F' does not move because it is insoluble in the solvent, which is the mobile phase

(iv) The food colouring that contains the dye that is likely to be most soluble in the solvent are does for which the dyes travel furthest, which are;

Food coloring 'E' and 'H'

(b) Using a similar question solution found on 'tutor my self' website, we have;

The [tex]R_f[/tex] values are given as follows;

[tex]R_f = \dfrac{Distance \ moved \ by \ dye}{Distance \ moved \ by \ solvent}[/tex]

The distance moved by the solvent = 5 units

The distance moved by dyes in food colouring 'E' and 'H' = 4 units

The distance moved by dye in food colouring 'G' = 3.3 units

The distance moved by the second dye in food colouring 'E' = 2.7 units

By inspection, we get;

[tex]R_f[/tex] dye in food colouring 'G' = 3.3/5 = 0.66,

Therefore, the dye with [tex]R_f[/tex] value closest to 0.67 is the dye in food colouring 'G'.

According to Avogadro's number, there are 27.10×10²³ atoms in  4.5 moles of Al.

What is Avogadro's number?

Avogadro's number is defined as a proportionality factor which relates number of constituent particles with the amount of substance which is present in the sample.

It has a SI unit of reciprocal mole whose numeric value is expressed in reciprocal mole which is a dimensionless number and is called as Avogadro's constant.It relates the volume of a substance with it's average volume occupied by one of it's particles .

According to the definitions, Avogadro's number depend on determined value of mass of one atom of those elements.It bridges the gap between macroscopic and microscopic world by relating amount of substance with number of particles.

Number of atoms can be calculated using Avogadro's number as follows: mass/molar mass×Avogadro's number.As 1 mole =6.023×10²³ atoms , thus,4.5 moles =4.5×6.023×10²³ = 27.10×10²³  atoms.

Thus, there are 27.10×10²³ atoms in  4.5 moles of Al.
