If an ion has a -2 charge, how many extra electrons do you add to the lewis structure

Answers

Answer:

add 2 extra electrons

Explanation:

This is because -2 means 2 electrons are gained while +2 means it lost two electrons.

If an ion has a charge of -2, you have to add two extra electrons to its Lewis structure.

The Lewis structure of a compound is a structure that shows the arrangement of electrons in the outermost or valence shell of an atom.

An ion is formed by adding or removing electrons from a specie. The magnitude of the resulting charge depends on the number of electrons added or removed from the specie.

To form a negative charge of magnitude -2, I have to add two electrons to the Lewis structure of the specie.

How many moles of oxygen are present in 0.798 moles of Mg(IO3)2?
Answer: 4.79 mol

Answers

Answer:

About 4.79 moles of oxygen.

Explanation:

We want to determine the amount of moles of oxygen are present in 0.798 moles of Mg(IO₃)₂.

From the chemical formula, we can see that there are six atoms of oxygen for every molecule of Mg(IO₃)₂. Therefore, we can say that there are six moles of oxygen for every mole of Mg(IO₃)₂. This yields the following ratio:

[tex]\displaystyle \frac{6\text{ mol O}}{1 \text{ mol Mg(IO$_3$)$_2$}}[/tex]

Multiplying this by the initial value yields:

[tex]\displaystyle 0.798 \text{ mol Mg(IO$_3$)$_2$} \cdot \displaystyle \frac{6\text{ mol O}}{1 \text{ mol Mg(IO$_3$)$_2$}} = 4.79 \text{ mol O}[/tex]

In conclusion, there are about 4.79 moles of oxygen present in 0.798 moles of Mg(IO₃)₂.

Jim makes a table that lists soluble and insoluble substances. Which statement best explains why the table is incorrect?

a table with the titles Soluble and Insoluble, written underneath Soluble is sugar, food coloring, and honey, and written underneath Insoluble is sand, grass, and salt

A. Food coloring is an insoluble substance.
b. Honey is an insoluble substance.
C. Grass is a soluble substance.
D. Salt is a soluble substance.

Answers

Answer:

D

Explanation:

The statement that best explains why the table is incorrect is: Grass is a soluble substance. Option C is correct.

In the table, grass is listed under "Insoluble," but in reality, grass is not a substance that dissolves in water. It is a complex mixture of various compounds, including cellulose and other organic materials, which are not water-soluble. Grass does not dissolve when added to water; instead, it remains intact and is not readily soluble.

On the other hand, all the other substances listed in the table are correctly categorized. Sugar, food coloring, and honey are soluble substances because they dissolve in water. Sand and salt are insoluble substances because they do not dissolve in water.

Hence, C. is the correct option.

How many moles of carbon are 8.7x1023 atoms of carbon?

Answers

You’ll need to set up a convention from moles over atoms to atoms over moles

One mole of every substance contains 6.022×10²³ number of atoms. One mole carbon have these much atoms and thus number of moles of carbon having 8.7 × 10²³ atoms is 1.44 moles.

What is carbon?

Carbon is 6th element in periodic table. It is a p block element and is a non-metal. Carbon forms covalent bonds with other elements.

One mole of every elements contains 6.022×10²³ number of atoms and it is called Avogadro number. Similarly one mole of a compound contains 6.022×10²³ number of molecules.

The number of atoms in one mole of carbon is 6.022×10²³.Therefore, number of moles of carbon which contains 8.7 × 10²³ atoms is calculated as follows:

number of moles of carbon = 8.7 × 10²³/6.022×10²³

                                              = 1.44 moles.

Therefore, the number of moles of carbon containing 8.7 × 10²³ atoms is 1.44 moles.

Scientists always consider that whenever there is an experiment, there is a tendency for a
decrease in the amount of the expected product. Is this result a violation of the law of
conservation of matter? Why or Why not?

Answers

The masses conservation law allows us to find that the answer for which the quantity of product is less than are:

There are other competitive competitive chemical reactions. Some of the reactants did not mix. The efficiency of the reaction is less than calculated.

One of the great conservation laws of science is the conservation of mass, therefore the initial mass is equal to the final mass, even in nuclear reactions where part of the mass is converted into energy, if it is taken into account mass and energy this mass-energy relationship is conserved.

In a chemical reaction the constituents mix and form new compounds, in an ideal case all the material of the constituents must react, but in real cases there is some part of the reactants that does not react in the required direction, therefore the amount of product is less than expected.

When adding the moles of the refractants and comparing with the moles of the product and the unreacted or reacted material in other products should be the same.

The fact that there is less product than expected in a reaction is due to the existence of other competitive reactions.

Consequently using the masses conservation law we can find that the quantity of products is less than expected are:  

There are other competitive competitive chemical reactions. Some of the reactants did not mix. The efficiency of the reaction is less than calculated.

Why are the components of the mixture separated ? Give any 6 reasons........​

Answers

We need to separate different components of a mixture to separate the useful components from the non-useful or some harmful components.

Examples:

(a) Tea leaves are separated from tea.

(b) Pebbles are separated form rice and pulse.

Explanation:

The mixtures are separated into their components for the following reasons:

1. To remove an undesirable component - Tea is made by boiling tea leaves in water and then adding milk and sugar. After the tea has been made, the used tea leaves become the undesirable component of the mixture 'tea' and are removed from it by using a tea strainer.

2. To remove a harmful component - Foodgrains like rice, wheat, pulses etc. usually contain small pieces of stones and some insects etc. These are harmful to us and are hence removed from the foodgrains before using them.

3. To obtain a pure sample of a substance - Tap water contains some dissolved salts in it so it is an impure mixture. This water is made free of dissolved salts or impurities by the process of distillation and as a result, we get a pure sample of water.

4. To obtain a useful component - Milk is a mixture from which useful component 'butter' is separated.
