1. 0.488M
2. 7.67mol
3. 7.67M
4. 0.000767M

Answers

Answer 1

Answer:

7.67

Explanation:

Answer 2

According to molar concentration, the molarity of solution which contains 22.41 grams of NaCl in 50.0 ml of solution is 7.67 M.

What is molar concentration?

Molar concentration is defined as a measure by which concentration of chemical substances present in a solution are determined. It is defined in particular reference to solute concentration in a solution . Most commonly used unit for molar concentration is moles/liter.

The molar concentration depends on change in volume of the solution which is mainly due to thermal expansion. Molar concentration is calculated by the formula, molar concentration=mass/ molar mass ×1/volume of solution in liters.

In terms of moles, it's formula is given as molar concentration= number of moles /volume of solution in liters.Substitution of values in the given formula gives, molarity= 22.41/58.44×1/0.05=7.67 M.

Thus, the  molarity of solution which contains 22.41 grams of NaCl in 50.0 ml of solution is 7.67 M.

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

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

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.

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.

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.
