What does the 2 mean in the formula of calcium nitrate? What does the 3
mean?

Answers

Answer:

Calcium nitrate is an inorganic compound with the chemical formula Ca(NO3)2. ... It is a nitrate salt of Calcium which contains calcium and nitrogen and oxygen. Calcium nitrate is a white or whitish-grey coloured granular solid which absorbs moisture from the air and is usually found as a tetrahydrate compound Ca(NO3)2.

Explanation:

3) Find the mass, in grams, of 5.08 mol Ca(NO3)2

Answers

Answer:

833.12g

Explanation:

Use the mole=mass/mr equation (rearrange this to find mass)

Mr= 164

So, 5.08 x 164 = 833.12g

The mass in grams of 5.08 mol Ca(NO3)2 is =833.12g

What is a mole?

The mole is the amount of substance of a gadget which includes as many standard entities as there are atoms in zero.012 kilogram of carbon 12;

Molecular mass of Ca(NO3)2 = 40+(14+48)*2

                                                =40+124

                                                = 164 g

1 mole of Ca(NO3)2 = 164 g

5.08 mole of = 5.08*164g

                         =833.12g

A. butylcyclohexane
B. butylcyclopentane
C. propylcyclohexane

Answers

Answer:

The answer for this question is A. butylcyclohexane

Explanation:

Choose letter A

You welcome have a nice day.

Name of the given compound is butyl cyclohexane.

What are cyclo alkanes?

Cyclo alkanes are those organic compounds in which alkanes are present in the cyclic form.

In the nomenclature of cyclo alkane, name of the substitute is put before the name of the main ring. In the given structure number of carbons in ring is 6 so that given cycloalkane is cyclohexane and butyl group is attached as substitute. So name of the given compound is butyl cyclohexane.

Butyl cyclopentane is wrong because 6 carbons are present in ring.Propylcyclohexane is also wrong because 4 carbons are attached in the ring.

Hence name of the compound is butyl cyclohexane.

An atom of an element always contains a proton, electron and neutron.

What is an atom ?

Every atom is made up of a nucleus and one or more electrons that are attached to the nucleus. One or more protons and a number of neutrons make up the nucleus. Only the most common type of hydrogen is neutron-free. Every solid, liquid, gas, and plasma is made up of atoms that are either neutral or ionized.

But when it comes to the word atom, we must go back to 400 B.C. Greece. And Democritus, a brilliant philosopher, proposed the Greek word atomos, which means uncuttable.

A balloon occupies 175 cm at 25.0 C. What volume will it occupy at 42.5 °C?

Answers

175 cm³ instead of 175 cm.

Answer:

297.5 cm³

Explanation:

From the question;

Initial volume; V1 = 175 cm³

Initial temperature; T1 = 25°C

Final temperature; T2 = 42.5°C

From Charles law we can find the volume V2 from the equation;

V1/T1 = V2/T2

Making V2 the subject gives;

V2 = V1 × T2/T1

V2 = (175 × 42.5)/25

V2 = 297.5 cm³

The chemical equation, Cr + Fe(NO3)2 → Fe + Cr(NO3)3, is an example of which type of reaction?

Answers

Answer:

Redox type

Explanation:

The reaction is:

2Cr +  3Fe(NO₃)₂ → 2Fe + 2Cr(NO₃)₃

2 moles of chromium can react to 3 moles of iron (II) nitrate in order to produce 2 moles of iron and 2 moles of chromium nitrate.

If we see oxidation state, we see that chromium changes from 0 to +3

Iron changed the oxidation state from +2 to 0

Remember that elements at ground state has 0, as oxidation state.

Iron is being reduced while chromium is oxidized. Then, the half reactions are:

Fe²⁺  +  2e⁻ ⇄  Fe    (Reduction)

Cr ⇄ Cr³⁺  +  3e⁻    (Oxidation)

When an element is being  reduced, while another is being oxidized, we are in prescence of a redox reaction.

O AX

O 3AX

Answers

Answer: it’s not A3X3

Explanation:

1. AX

For binary ionic compounds (ionic compounds that contain only two types of elements), the compounds are named by writing the name of the cation first followed by the name of the anion.If a cation A carries +3 charge and an anion X carries -3 charge, the compound so formed is AX. Since the charges gets cancelled out.For example: consider aluminum phosphate, aluminum carries +3 charge and phosphate carries -3 charge, the molecular formula for the compound will be AlPO₄.

How many moles of carbon dioxide are produced when 5.12 moles of glucose undergoes a combustion reaction?

Answers

Answer: 30.72 moles of [tex]CO_2[/tex] will be produced from 5.12 moles of glucose.

Explanation:

The balanced chemical equation for combustion of glucose is:

[tex]C_6H_{12}O_6+6O_2\rightarrow 6CO_2+6H_2O[/tex]  

According to stoichiometry :

1 moles of glucose produce =  6 moles of [tex]CO_2[/tex]

Thus 5.12 moles of glucose produce =[tex]\frac{6}{1}\times 5.12=30.72moles[/tex]  of [tex]CO_2[/tex]

Thus 30.72 moles of [tex]CO_2[/tex] will be produced from 5.12 moles of glucose.
