Answer: Option (a) is the correct answer.

Explanation:

Ionic compounds are the compounds which are formed by transfer of electrons.

Atoms of ionic compounds are attached together by strong force of attraction due to opposite charges on its atoms.

Also, ionic compounds readily dissociate into ions.

Therefore, we can conclude that ionic type of compound dissociates.

Saponification is a chemical reaction _____. A. due to the presence of a strong organic acid. B. that results in an alcohol and

dezoksy [38]

Answer:

that results in an alcohol and a carboxylic acid.

Explanation:

Saponification is a chemical reaction process of alkaline hydrolysis of esters(R'COOR group) by which soap is obtained.

For Example, when a base such as sodium hydroxide [NaOH] is used to hydrolyze an ester, the products are a carboxylate salt and an alcohol. Because soaps are prepared by the alkaline hydrolysis of fats and oils.

In a saponification reaction, alkaline hydrolysis of fats and oils with sodium hydroxide yields propane-1,2,3-triol and the corresponding sodium salts of the component fatty acids.

i.e Fat or oil + caustic alkali ⇒ Soap + propane-1,2,3-triol

As a specific example, ethyl acetate and NaOH react to form sodium acetate and ethanol:

Select all steps below that you followed to practice laboratory safety during the experiment. used tongs or a test tube holder t

uysha [10]

Explanation:

Steps followed to practice laboratory safety during the experiment are as follows.

Used tongs or a test tube holder to hold materials over the Bunsen burner flame.
Wore gloves and goggles.
Made careful observations of the products and reactants.
Did not smell the gases produced.

When we heat a test tube over bunsen flame then the tube gets hot and when we hold it with bare hands then out hands will burn. Therefore, it is advised to hold test tube with the help of tongs or a holder so that our hands did not burn.

We should also wear gloves and goggles so that any acid would not spill directly on our hands, skin and eyes as it can affect or damage the skin severely.

Careful observations were made so that correct calculations about the experiment can be carried out.

It is also advised that we should not smell the gases produced but gases move freely from one place to another in a laboratory or any where else.

So, we can try to avoid it by covering our mouth with a cloth but we cannot stop it. If we keep on inhaling the gases produced in a laboratory then it can also lead to severe disease or defect in the human body.

Which sample contains more atoms: 3.89 g of nickel or 6.61 g of silver? defend your answer

Lubov Fominskaja [6]

Nickel contains more atoms.

<u>Explanation:</u>

Number of atoms is determined by the Avogadro number.

1 mole of substance contains 6.022 X 10²³ atoms.

Given:

Mass of Nickel, Ni = 3.89g

Molecular weight of Ni = 58.6934g

Number of moles of Ni = 3.89/58.6934g

Number of atoms of Ni = $\frac{3.89 X 6.022 X 10^2^3}{58.6934}$

Number of atoms of Ni = 0.39 X 10²³

Mass of silver, Ag = 6.61g

Molecular weight of Ag = 107.8682g

Number of moles of Ag = 6.61/107.8682

Number of atoms of Ag = $\frac{6.61 X 6.022 X 10^2^3}{107.8682}$

Number of atoms of Ag = 0.36 X 10²³

Therefore, Nickel contains for atoms.

Which of the following atoms would be expected to form positive ions in binary ionic compounds: Br, Ca, Na, N, F, Al, Sn, S, Cd?

Montano1993 [528]

Answer:

Explanation:

Hello,

Binary ionic compounds are those compounds that consist of two elements and usually one has a positive ion while the other one carries a negative ion and they both combine together to form a compound.

In the options above, option A is the right answer because it has a combination of positive ions.

For ionic compounds to form, a strong electropositive element must combine with a strong electronegative element.

Most metals are usually electropositive and carry a positive ion and non metals tends to carry negative ions.

Br = non metal = negative ion

Ca = metal = positive ion

Na = metal = positive ion

N = non metal = negative ion

F = non metal = negative ion

Al = metal = positive ion

Sn = metal = positive ions

S = non metal = negative ion

Cd = metal = positive ion

Option A has a combination of all the positive ions here.
