Answer:

[HC2H3O2] > NaC2H3O2

Explanation:

The concentration of [tex]\rm HC_2H_3O_2[/tex] has been higher than the concentration of [tex]\rm NaC_2H_3O_2[/tex].

The pKa has been defined as the acid constant that has been used for the determination of the strength of the acid. The higher the pKa value, the weaker the acid has been.

The [tex]\rm HC_2H_3O_2[/tex] has the pka value 4.8 depicting the solution has been a pH 4.8. With the addition of [tex]\rm NaC_2H_3O_2[/tex], the pH has been shifted towards the acidic condition, thus the Hydrogen concentration has been higher.

The change in the pH has been resulted in the reduction in the pH from the basic to acidic condition. Since the concentration of the [tex]\rm HC_2H_3O_2[/tex] has been higher than the [tex]\rm NaC_2H_3O_2[/tex] concentration, the pH has been shifted towards the more acidic condition.

Thus, the concentration of [tex]\rm HC_2H_3O_2[/tex] has been higher than the concentration of [tex]\rm NaC_2H_3O_2[/tex].

Answer: 720 g

Explanation:

To solve this we must be knowing each and every concept related to mole. Therefore, shivani measures out 6.0 moles of epsom salt (MgSO[tex]_4[/tex]) to put her bath. 1,566g MgSO[tex]_4[/tex] went in the bath.

A mole is merely a measuring unit. In reality, it is one of its International System of Units' seven foundation units. When current units are insufficient, new units are created.

Chemical reactions frequently occur at levels where employing grams would be inappropriate, but using absolute quantities of atoms/molecules/ions would also be misleading.

For all practical reasons, one mole of a substance in grams is nearly equal to 1 molecule for the compound per daltons.

Mathematically,

number of mole =given mass ÷ molar mass

number of mole=6.0 moles

molar mass of epsom= 261.47g/mol

substituting all the given values in the above equation, we get

6.0 moles =mass of epsom ÷ 261.47g/mol

mass of epsom =1,566g

Therefore, 1,566g  MgSO[tex]_4[/tex] went in the bath.

Explanation:

The oxidation number of  Sulphur = +2

General formula for determining Oxidation Numbers :

1. The number of oxidation of single element atoms = 0. Examples of Ar, Mg, Cu, Fe, N₂, O₂, etc. = 0

Group I : +1

Group II : +2

H in compound = +1, except metal hydride compounds (Hydrogen which binds I or II groups) oxidation number H = -1, for example, LiH, MgH₂, etc.

2. Oxidation number O in compound = -2, except OF2 = + 2 and in peroxide (Na₂O₂, BaO₂) = -1 and superoxide, for example KO₂ = -1/2.

3 The oxidation number in a non-filled compound = 0,

The total amount of oxidation in ion = ion charge, Example NO₃⁻ = -1

Sodium thiosulphate​ - Na₂S₂O₃

Oxidation number Na = +1 ⇒x2 = +2

Oxidation number O = -2 ⇒x3 = -6

Oxidation number Na₂S₂O₃ = 0

2.Na+2.S+3.O=0

2.+1+2.S+3.(-2)=0

2+2S-6=0

-4+2S=0

2S=4

S=+2

Answer:

3

Explanation:

The reaction expression is given as:

      Al(OH)₃  +   HNO₃   →    H₂O   +  Al(NO₃)₃  

To solve this problem, let us assign coefficient a,b,c and d to each specie;

           aAl(OH)₃  +   bHNO₃   →    cH₂O   +  dAl(NO₃)₃  

Conserving Al : a  = d

                   O:  3a + 3b  = c + 9d

                   H: 3a + b  = 2c

                   N: b  = 3d

let a = 1 , d  = 1, b  = 3 , c = 3

  Multiply through by 3;

 a  = 1, b  = 3, c = 3 and d  = 1

   Al(OH)₃  +   3HNO₃   →    3H₂O   +  Al(NO₃)₃  

Answer:

Compound 1- ionic solid

Compound 2- can't really decide

Compound 3- molecular solid

Explanation:

An ionic solid has a very high melting point. It is hard but not brittle. It's solution or melt but not it's solid conducts electricity. Compound 1 is an ionic solid.

We can't really decide on compound 2 since it is brittle yet it's solution conducts electricity.

Lastly, compound 3 is a molecular solid since it has a low melting point.

Answer:

Compound 1- ionic solid

Compound 2- can't really decide

Compound 3- molecular solid

Answer:

Option B. Single replacement reaction

Explanation:

To know which option is correct, it is important that we know the definition of each option. The definition of each option is given below:

1. Synthesis reaction is a reaction in which two different elements or compound combine together to produce a new compound different from the two starting elements or compound. An example is illustrated below:

C + D —> E

2. Single replacement reaction is a reaction in which an element replaces or displaces another element in a compound. An example is illustrated below:

D + BC —> B + CD

3. Combustion reaction is a reaction in a substance react with oxygen to generate carbon dioxide (CO₂) and water (H₂O). An example can be seen when organic compound react with oxygen to produce carbon dioxide (CO₂) and water (H₂O). This is illustrated below:

CₓHᵧ + (x + y/4) O₂ —> xCO₂ + (y/2) H₂O

4. Double replacement reaction is a reaction in which the ions of the two reacting compound replaces one another to form new products. This is illustrated below:

X⁺Y¯ + U⁺V¯ —> X⁺V¯ + U⁺Y¯

5. Decomposition reaction is a reaction in which a large compound breaks down into two or more elements or compound. An example is illustrated below:

GH —> G + H

Now, observing the equation given in the question above:

Sn + 2HCl —> SnCl₂ + H₂

We can see that Sn replaces H in HCl to produce SnCl₂.

Therefore, the reaction is a single replacement reaction.

[tex]m_{Fe(OH)_3} = 0.891gFe(OH)_3[/tex]

Explanation:

Hello!

In this case, given the chemical reaction:

[tex]3NaOH(aq)+Fe(NO_3)_3(aq)\rightarrow 3NaNO_3(aq)+Fe(OH)_3(s)[/tex]

In such a way, given the volumes and molarities of each reactant, we can compute the moles of produced iron (III) hydroxide by each of them, via the 3:1 and 1:1 mole ratios:

[tex]n_{Fe(OH)_3}^{by\ NaOH}=0.0500L*0.500\frac{molNaOH}{L}*\frac{1molFe(OH)_3}{3molNaOH} =0.00833molFe(OH)_3\\\\n_{Fe(OH)_3}^{by\ Fe(NO_3)_3}=0.0750L*0.200\frac{molFe(NO_3)_3}{L}*\frac{1molFe(OH)_3}{1molFe(NO_3)_3} =0.0150molFe(OH)_3[/tex]

It means that the sodium hydroxide is the limiting reactant and 0.00833 moles of iron (III) hydroxide are produced; thus, the required mass is:

[tex]m_{Fe(OH)_3}=0.00833molFe(OH)_3*\frac{106.87gFe(OH)_3}{1molFe(OH)_3} \\\\m_{Fe(OH)_3} = 0.891gFe(OH)_3[/tex]
