explain why division by zero is undefined​

Answers

Answer 1

Answer:

Division by zero is undefined because there is no other number to divide it by.

Explanation:

Unlike 2/2, 2/0 doesn't have anything to divide the 2 by which makes it undefined and impossible to solve.

Answer 2

The division by zero is undefined​, because whatever response we may give, we will then have to concur that the answer times 0 = 1, which is illogical because anything multiplied by zero is zero.

Why division by zero is undefined​ ?

Since any attempt at definition results in a contradiction, the outcome of a division by zero cannot be defined. a=r*b. r*0=a. (1) (1) But because r*0=0 for all r, there is no solution to the equation unless a=0 (1).

Again, mathematicians have left zero divided by zero as an open problem because they are both equally valid and, to be honest, neither of them is consistent with the rest of mathematics.

Mathematically, it is impossible to divide a number by zero, just as in this illustration. Or, at the very least, there isn't currently a means to do that. Numerous attempts have been made to figure out how to divide by zero, as mathematicians are constantly looking for solutions to intriguing mathematical issues.

Thus, The division by zero is undefined​, because whatever response we may give, we will then have to concur that the answer times 0 = 1.

What ions are present in an aqueous solution of NiCl2?

Answers

Answer:

Ni²⁺ and Cl⁻ ions

Explanation:

NiCl₂ is an ionic compound which is composed by 2 chloride ions (Cl⁻) and 1 nickel (II) ion (Ni²⁺). It dissociates in water as follows:

NiCl₂ ⇒ Ni²⁺ + 2 Cl⁻

Therefore, in an aqueous solution of NiCl₂ will be present Ni²⁺ ions and Cl⁻ ions.

What is the freezing point of an aqueous 1.00 m NaCl solution? (Kf = 1.86 *C/m) (Assume complete dissociation of the salt.)

Answers

Answer:

The freezing point is -3.72 degrees Celsius

Explanation:

In this question, by assuming the complete dissociation of the salt, we want to calculate the freezing point of an aqueous 1 M NaCl solution .

We proceed as follows;

Firstly, we write the dissociation equation;

NaCl ——> Na+ + Cl-

So the number of ions present in the dissociation is 2. This means that the Vant Hogg factor also called I = 2

Mathematically;

ΔTf = Kf*m*i

m represents the molality which is given as 1

So by substituting the values, we have;

ΔTf = 1.86 * 1 * 2 = 3.72 degrees Celcius

The freezing point however is 0 - ΔTf = 0 - 3.72 = -3.72 degrees Celcius

An element is an arrangement of atoms in a particular way; True or False?

Answers

Answer:

In an atom of an element there are a fixed number of electrons. If the total mass of electrons in 1 mole (6.022 x 1023) of atoms of a certain element is 18.65 mg, how many protons must there be in the nucleus of that atom? (mass of electron = 9.109 x 10–28 g).

Answers

Answer:

No. of protons = 34

Explanation:

First we need to calculate the number of electrons in one mole of the the element:

No. of electrons per mole = Total Mass of Electrons/Mass of 1 Electron

No. of electrons per mole = (18.65 x 10⁻³ g)/(9.109 x 10⁻²⁸ g)

No. of electrons per mole = 2.04 x 10²⁵ electrons/mol

Now, we calculate the no. of electrons in 1 atom:

No. of electrons per atom = No. of Electrons per mole/No. of atoms per mole

No. of electrons per atom = (2.04 x 10²⁵ electrons/mol)/(6.022 x 10²³ atoms/mol)

No. of electrons per atom = 34 electrons/atom

Since, the no. of protons in a pure element are equal to the number of electrons. Therefore,

No. of protons = 34

In this exercise we have to use the knowledge of atoms to calculate the number of protons, in this way we find:

Protons will be  34

First we need to reckon the number of electrons fashionable individual blemish of the the place where one feels comfortable:

[tex]electrons \ per \ mole = Total\ Mass\ of \ Electrons/Mass\ of\ 1 \ Electron\\ electrons\ per\ mole = (18.65 * 10^{-3} g)/(9.109 * 10^{28} g)\\ electrons \ per \ mole = 2.04 x 10^{25} electrons/mol[/tex]

Now, we plan on the electrons in 1 smallest part of something:

[tex]electrons\ per\ atom = Electrons\ per\ mole/atoms\ per\ mole\\ electrons\ per\ atom = (2.04 * 10^{25} electrons/mol)/(6.022 * 10^{23} atoms/mol)\\ electrons\ per\ atom = 34 electrons/atom [/tex]

If the chemical reaction AB + CD ⟶ AD + BC releases heat, what is true of the stored bond energy of the reactants and products? The bonds do not have energy, the atoms release heat. The bond energy of the reactants is the same as the bond energy of the products. The bond energy of the reactants is lower than the bond energy of the products. The bond energy of the reactants is higher than the bond energy of the products.

Answers

Answer:

The correct option is the last option

Explanation:

The chemical reaction provided in the question is a double-displacement reaction which is an exothermic reaction (which is the reason for the release of heat). An example of a double displacement reaction and exothermic reaction is the neutralization reaction illustrated below.

HCl + NaOH ⇒ NaCl + H₂O

From the law of conservation of energy, energy can neither be created nor destroyed, hence the total energy in a given system should ordinarily be the same (in the reactants and products), however when energy is released in a reaction (as in the case with an exothermic reaction), it shows there are more bond energy in the reactants than in the products and it is the excess energy that is been released into the atmosphere.

What will be the cost of gasoline for a 4,700-mile automobile trip if the car gets 41 miles per gallon, and the average price of gas is $3.79 per gallon?

Answers

Answer:

Idk

Explanation:

Find the gallons needed by dividing total miles by miles per gallon:

4700/41 = 114.634 gallons

Multiply the gallons needed by price per gallon:

114.634 x 2.79 = $319.83 Total

Round the answer as needed.

If gallons were rounded to 115 gallons total cost would be $320.85

Answer:

$ 434.40

Explanation:

41 miles ............ 1 gallon

4700 miles .......x gallon

x = 4700×1/41 = 114.63 gallons

114.63 gallons×$3.79 ≈  $ 434.40

In this way, ph is determined by hydrogen ion concentration . In the case of neutral solution [H+] =10-7 which we call a ph of 7. This means, for example, that a hydrogen-ion concentration of a solution with a ph of 4 is 10-4 mol/l, meaning it contains 0.0001 mole of hydrogen ion in a solution of 1 liter.

2nd )  CBr4  has a tetrahedral shape its a nonpolar compound (London bond )

           but  the water is polar molecules  has a  ( hydrogen bond ) its  molecular shape (bent shape)  . Both do not dissolve in each other because they have a different kinds of bond so they are  not a homogenous solution .

3rd) its a homogenous because the water can dissolve the ionic bonds between the Li (  cation ) and  (NO3 -1  anion ).

4th ) here we can say alcohol can dissolve in a little amount why ?

    pentane has a London force bond Alcohol has two different parts  first  part  has OH making hydrogen bond which cant dissolve in the pentane different kinds of bonds ,and the other part -CH3 has a London force bond that can dissolves easily in the pentaneso  one part dissolves but  the other part  can't dissolve so the two compound are slightly dissolves in each other  that which mean its not a homogenous solution

Explanation:

1. Calcium atom, Ca has 20 protons and 20 electrons. On the other hand, Calcium ion, Ca^2+ has 20 protons and 18 electrons. This is true because the +2 charge on the calcium ion, Ca^2+ indicates that the calcium atom, Ca has loss 2 electrons.

From the above illustration we can say that calcium ion, Ca^2+ has the following:

Proton = 20

Electron = 18

Therefore, diagram C indicates calcium ion, Ca^2+.

2. Fluorine atom, F has 9 protons and 9 electrons. Fluoride ion, F¯ has 9 protons and 10 electrons. This is so because the –1 charge on the fluoride ion, F¯ indicates that the fluorine atom, F has gained 1 electron.

Thus, we can say that the fluoride ion, F¯ has the following:

Proton = 9

Electron = 10

Therefore, diagram A represent fluoride ion, F¯.
