0.500 mol aluminium hydroxide, Al(OH)3 reacts with 0.500 mol sulphuric acid, H2SO4 to produce aluminium sulphate and water.
a) Write the balanced equation for the reaction.

b) Which reactant is limiting reactant?

c) How many moles of excess reactant is used in the experiment?

d)Determine how many moles of aluminium sulphates was obtained if the percentage yield of aluminium sulphate during the experiment is 77%.

[9 marks]​

Answers

Answer 1

a) The balanced equation for the reaction would be as follows:

[tex]2 Al(OH)_3 + 3 H_2SO_4 ---> Al_2(SO_4)_3 + 6 H_2O[/tex]

b) The mole ratio of aluminum hydroxide to sulfuric acid is 2:3. This means that every 1 mole of the aluminum hydroxide would require 1.5 moles of sulfuric acid.

0.5 mole aluminum hydroxide would require:

         0.5 x 3/2 = 0.75 moles of sulfuric acid.

But only 0.500 moles of sulfuric acid is present. Thus, the limiting reagent is sulfuric acid.

c) With 0.5 moles sulfuric acid, the mole of aluminum hydroxide required would be:

             0.5 x 2/3 = 0.33

Excess moles of aluminum hydroxide = 0.5 - 0.33

                                                              = 0.17 moles

d) The mole ratio of sulfuric acid to aluminum sulfate produced is 3:1. With 0.5 moles sulfuric acid, the mole of aluminum sulfate produced would be:

        0.5 x 1/3 = 0.17 moles

But the percentage yield is 77%

   77/100 x 0.17 = 0.13 moles

Thus, the moles of aluminum sulfate that would be obtained with a percentage yield of 77% would be 0.13 moles.

What is the initial concentration of a solution if 40.0 mL is diluted to make 720 mL of a 0.45 M solution?

Answers

Answer:

8.1 M

Explanation:

What is the initial concentration of a solution if 40.0 mL is diluted to make 720 mL of a 0.45 M solution?

LET Y = INITIAL CONCENTRATION

SO

Y TIMES 40/720 = 0.45 m

SO

Y= (0.45) X 720/40=

0.45 X 72/4 =

0.45 X 18 =8.1 M

Concentration is related to the mass and volume. 8.1 M  initial concentration of a solution is required if 40 ml is diluted to make 720 ml of a 0.45 M solution.  

What is initial concentration ?

The first measured concentration of a compound in a substance is called as initial concentration. Initial concentration also measure with the help of molarity.

Write out the equation C = m ÷ V, where m is the mass of the solute and V is the total volume of the solution. Substitute  the values you found for the mass and volume, and divide them to find the concentration of your solution.  

Let X is the initial concentration,

so, X times 40 ÷ 720 = 0.45

X = ( 0.45 ) × ( 720÷40)

= 0.45 × 18

= 8.1 M

Hence, 8.1 M  initial concentration of a solution is required .

The city council of a small town wanted to add fluoride to their water so that all the residents would have healthier teeth. The mayor had read that ionic compounds must be used to get the fluoride into water. He looked up fluorine-containing compounds and came up with the following list. ​
NaF NF3 SiF4 CaF2 NH4F​

Using academic vocabulary in paragraph form, discuss the following: ​

Explain which compound(s) could produce fluoride ions in the water. In your response, be sure to include: ​
° which of the listed compounds are ionic and which are covalent. ​
° how ionic and covalent compounds are different. ​
° why only ionic compounds would produce fluoride in water.​

Answers

Answer:NaF is ionic. NF3 is covalent. SiF4 is ionic. CaF2 is Ionic and  NH4F is also ionic. Ionic compounds transfer electrons whereas covalent compounds share electrons hence the word "co". Also, ionic compounds are formed with metal and nonmetal. Where a covalent is with 2 nonmetals. Only ionic compounds would produce fluoride in water because ionic compounds can dissolve in water and covalent compounds cant.

The compounds that can be used for the release of fluorine in water are NaF, [tex]\rm SiF_4[/tex], [tex]\rm CaF_2[/tex], and [tex]\rm NH_4F[/tex].

The ionic compounds are formed by the transfer of electrons between the atoms of the compounds. The ionic bonds are weaker and are easy to dissociate in the aqueous solution.

The covalent compounds are formed by the sharing of electrons between the atoms. Since there is sharing, there has been a strong bond, that has been hard to dissociate.

The Mayor has to release Fluoride in the water, thus ionic compounds are preferred that have the easy release of fluorine.

From the given compounds:

NaF = Ionic compound[tex]\rm NF_3[/tex] = Covalent compound[tex]\rm SiF_4[/tex] = Ionic compound[tex]\rm CaF_2[/tex] =  Ionic compound[tex]\rm NH_4F[/tex] =  Ionic compound

Thus the compounds that can be used for the release of fluorine in water are NaF, [tex]\rm SiF_4[/tex], [tex]\rm CaF_2[/tex], and [tex]\rm NH_4F[/tex].

Calculate the maximum mass of magnesium oxide that could be produced in the reaction.

Oxygen exist in nature as O2, diatomic.

so

The student burns 10 g of magnesium in air to produce magnesium oxide (MgO).

2Mg + 02 + 2MgO

Calculate the maximum mass of magnesium oxide that could be produced in the reaction.

2 moles of Mg produce 2 moles of MgO

1 mole of Mg weighs 24.3 and produces 1 mole of MgO

Mg HAS AN ATOMIC MASS OF 24.3

Mg HAS A MOLAR MASS OF 24.3 +16 = 40.3gm/mole

so 24.3 gm of Mg produce 40.3 gm MgO

set up the ratio

10 gm Mg/x of MgO  = 24.3/40.3

or

10/x = 24.3/40.3

cross multiply and isolate x (use Algebra I)

24.3x =403

x=403/24,3 = 16.58 gm MgO

if 10.5 grams of liquid water is boiled how many grams of water vapor will then form ?

Answers

Answer:

Explanation:

This could vary depending on the exact temp, time and minerals. something with alot of salt boils quicker than something without it, so 10.5 grams?

The particular temperature, the passage of time, and the minerals could all affect the amount of grams of liquid water.

What are minerals?

Minerals are defined as a naturally crystallized element or chemical compound that was created through geological processes. Natural materials are those that form on their own, such as minerals. Minerals don't droop, melt, or evaporate since they are solids. In contrast to the carbon compounds found in living organisms, minerals are inorganic. Minerals are crystalline: They have a unique atomic composition and arrangement.

Temperature is defined as a measure of hotness or coldness expressed in terms of any number of arbitrary scales that shows the direction that heat energy will naturally flow, i.e., from a hotter body to a colder body. The three temperature scales that are now in use are Kelvin, Celsius, and Fahrenheit. Food, beverages, agriculture, and medical care for both people and animals all depend heavily on temperature.

Thus, the particular temperature, the passage of time, and the minerals could all affect the amount of grams of liquid water.
