Answer:

Explanation:

Florine has the highest electronegativity and it thus pulls the element of [tex]$OH^-[/tex] groups in the COOH group towards itself, making it relatively easy to loose the proton of the carboxyl group.

What resists pH change by reacting with acids and bases?

Answers

A buffer resists the change of ph. That is because a buffer is made of an acid and it’s conjugate base. This mixture will react with any solution that is added to neutralize it. If an acid is added to a buffer, the base in that buffer will react with the added acid to create water and a neutral salt. This reaction results in very little ph change

A 16.4 g sample of calcium chloride is dissolved in enough water to make 750.0 mL of solution. Calculate the molarity of calcium chloride in this solution. plz help!!!

Answers

SIMP FOR LEVI AKRAMEN

The molarity is an important method to calculate the concentration of a solution. The molarity of calcium chloride of 16.4 g in 750.0 mL of solution is 0.196 mol L⁻¹.

What is molarity?

The molarity of a solution is defined as the number of moles of the solute present per litre of the solution. It is mainly employed in calculating the molarity of a binary solution. It is represented as 'M' and unit is mol L⁻¹.

The equation used to calculate the molarity is given as:

Molarity = Number of moles of the solute / Volume of the solution in litres

Molar mass of CaCl₂ = 110.98 g/mol

Given mass = 16.4 g

Number of moles = 16.4 / 110.98 = 0.147

750.0 mL = 0.75 L

Molarity = 0.147 / 0.75 = 0.196 mol L⁻¹

Thus the molarity is 0.196 mol L⁻¹.

Answers

What is the molar mass of aspartic acid, C404H7N?

ANSWER: 133g/mol

The molar mass of aspartic acid is 133.05g/mol.

What is molar mass?

The molar mass is the mass per unit amount of substance of a given chemical entity. It is denoted by a symbol M. The SI unit of molar mass is kg/mol.

What is aspartic acid?

Aspartic acid is one of the building-block of amino acids which is responsible for synthesizing proteins and regulating hormones in the human body.

The chemical formula of aspartic acid is C4H7NO4.

Atomic mass of C = 12.011u, H = 1.007u, N = 14.006u, O = 16u

Molar mass of C4H7NO4 = 4(12.011)+7(1)+14.006+4(16)

                 = 48.044+7+14.006+64

                 = 133.05g/mol

Hence, the molar mass of aspartic acid is 133.05g/mol.

How much excess reactant is leftover after if 6.30g of ammonia react with
1.80g of oxygen?

Answers

Answer:

5.52 g

Explanation:

4NH₃ + 5O₂ → 4NO + 6H₂O

First we convert the given masses of both reactants into moles, using their respective molar masses:

6.30 g NH₃ ÷ 17 g/mol = 0.370 mol NH₃ 1.80 g O₂ ÷ 32 g/mol = 0.056 mol O₂

Now we calculate with how many NH₃ moles would 0.056 O₂ moles react, using the stoichiometric coefficients:

0.056 mol O₂ * [tex]\frac{4molNH_3}{5molO_2}[/tex] = 0.045 mol NH₃

As there more NH₃ moles than required, NH₃ is the excess reactant.

Then we calculate how many NH₃ moles remained without reacting:

0.370 mol NH₃ - 0.045 mol NH₃ = 0.325 mol NH₃

Finally we convert NH₃ moles into grams:

0.325 mol NH₃ * 17 g/mol = 5.52 g

During a lab experiment performed at STP conditions, you prepare HCl by reacting 100. ml of Cl2 gas with an excess of H2 gas.
How many ml of a solution of Ba(OH)2 0.230M do you need to neutralize all the HCl produced?

Answers

Answer:

19.4 mL Ba(OH)2

Explanation:

H2(g) + Cl2(g) --> 2HCl(aq) (make sure this equation is balanced first)

At STP, 1 mol gas = 22.4 L gas. Use this conversion factor to convert the 100. mL of Cl2 to moles.

0.100 L Cl2 • (1 mol / 22.4 L) = 0.00446 mol Cl2

Use the mole ratio of 2 mol HCl for every 1 mol Cl2 to find moles of HCl produced.

0.00446 mol Cl2 • (2 mol HCl / 1 mol Cl2) = 0.00892 mol HCl

HCl is a strong acid and Ba(OH)2 is a strong base so both will completely ionize to release H+ and OH- respectively. You need 0.00892 mol OH- to neutralize all of the HCl. Note that one mole of Ba(OH)2 contains 2 moles of OH-.

0.00892 mol OH- • (1 mol Ba(OH)2 / 2 mol OH-) • (1 L Ba(OH)2 / 0.230 M Ba(OH)2) = 0.0194 L = 19.4 mL Ba(OH)2

The first step in answering this reaction is to write down the required reaction equations and then answer the questions from stoichiometry(mass-mole relationship).

The first equation is;

[tex]H2(g) + Cl2(g) ------->2HCl(g)[/tex]

The second equation is

[tex]2HCl(g) + Ba(OH)2(aq) -------> BaCl2(aq) + 2H2O(l)[/tex]

From stoichiometry;

1ml = 1cm3

Since hydrogen is in excess, chlorine is the limiting reactant

1 mole of Cl2 occupies 22400cm3

x moles of Cl2 occupies 100cm3

x = 1 * 100/22400

x = 0.00446 moles of Cl2

According to the reaction equation;

1 mole of Cl2 yields 2 moles of HCl

0.00446 moles of Cl2 yields 0.00446 * 2/1

= 0.00892 moles of HCl

From the reaction equation;

2 moles of HCl reacts with 1 mole of Ba(OH)2

0.00892 moles of HCl reacts with 0.00892 * 1/2 = 0.00446 moles of Ba(OH)2

Since 0.00446 moles of Ba(OH)2 reacted

number of moles = concentration * volume

number of moles =  0.00446 moles

concentration = 0.230M

Let the volume in ml be V

0.00446 =  0.230 * V/1000

V = 0.00446 * 1000/ 0.230

V = 19.39 ml

Volume in ml = 19.39 ml of Ba(OH)2

Potassium chlorate decomposes to produce potassium chloride and oxygen gas according to the balanced equation below. If 1.00 g of potassium chlorate decomposes, and 0.500 g of solid potassium chloride is collected, what is the theoretical yield of potassium chloride and the % Yield of potassium chloride

Answers

Answer: The theoretical yield of potassium chloride is 0.596 grams and the % Yield of potassium chloride is 83.9%

Explanation:

To calculate the moles :

[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex]    

[tex]\text{Moles of} KClO_3=\frac{1.00g}{122.5g/mol}=0.008moles[/tex]  

[tex]2KClO_3\rightarrow 2KCl+3O_2[/tex]  

According to stoichiometry :

2 moles of [tex]KClO_3[/tex] produce= 2 moles of [tex]KCl[/tex]

Thus 0.008 moles of [tex]KClO_3[/tex] will produce=[tex]\frac{2}{2}\times 0.008=0.008moles[/tex]  of [tex]KCl[/tex]

Theoretical yield of [tex]KCl=moles\times {\text {Molar mass}}=0.008moles\times 74.5g/mol=0.596g[/tex]

% yield = [tex]\frac{\text {Actual yield}}{\text {Theoretical yield}}\times 100=\frac{0.500g}{0.596g}\times 100\%=83.9\%[/tex]

The theoretical yield of potassium chloride is 0.596 grams and the % Yield of potassium chloride is 83.9%
