Hydrolysis of amide gives Carboxylic acid and ammonium salts while in base medium we get amine along with Carboxylic acid. the products formed are shown in the 1st attachment.
An amide is a functional group in organic chemistry that consists of a carbonyl group (C=O) linked to a nitrogen atom (NH2 or NH-). The general structural formula for an amide is R-C(=O)-NR' where R and R' can be any organic group. Amides are a class of compounds that have a wide range of applications in various fields, from medicine to agriculture. They are found in many natural products, such as peptides and proteins, and also in many synthetic compounds. Hydrolysis is a chemical reaction that uses water to break down a compound. The addition of a water molecule (H2O) to a substrate typically results in the separation of that substrate into two smaller molecules, one of which is a hydroxide ion (OH-). The other molecule formed in the reaction is determined by the substrate being hydrolyzed.

A student determines the molar mass of acetone, CH3COCH3, by the method used in this experiment. She found that the equilibrium temperature of a mixture of ice and water was 1.0 degrees C on her thermometer. When she added 11.1 g of her sample to the mixture, the temperature, after thorough stirring, fell to -3.0 degrees C. She then poured off the solution through a screen into a beaker. The mass of the solution was 90.4 g.a) What was the freezing point depression?b) What was the molality of acetone? I need help especially with this one.c) How much acetone was in the decanted solution?d) How much water is in the decanted solution?e) How much acetone would there be in a solution containing 1 kg of water and acetone at the same concentration as she had in her experiment?f) What did she find to be the molar mass of acetone, assuming she made the calculation properly?
Answers
Answer:
(a). 4°C, (b). 2.4M, (c). 11.1 g, (d). 89.01 g, (e). 139.2 g and (f). 58 g/mol.
Explanation:
Without mincing words let's dive straight into the solution to the question.
(a). The freezing point depression can be Determine by subtracting the value of the initial temperature from the final temperature. Therefore;
The freezing point depression = [ 1 - (-3)]° C = 4°C.
(b). The molality can be Determine by using the formula below;
Molality = the number of moles found in the solute/ solvent's weight(kg).
Molality = ( 11.1 / 58) × (1000)/ ( 90.4 - 11.1) = 2.4 M.
(c). The mass of acetone that was in the decanted solution = 11.1 g.
(d). The mass of water that was in the decanted solution = 89.01 g.
(e). 2.4 = x/ 58 × (1000/1000).
x = 2.4 × 58 = 139.2 g.
(f). The molar mass of acetone = (12) + (1 × 3) + 12 + 16 + 12 + (1 x 3) = 58 g/mol.
Explain why anhydrous aluminium chloride is fairly soluble in organic solvent while anhydrous magnesium chloride is insoluble
Answers
Answer:
The correct answer is - anhydrous aluminum chloride is covalent whereas anhydrous magnesium chloride is ionic.
Explanation:
Anhydrous aluminum chloride is a covalent compound and we know that covalent compounds have less or no polarity. Organic compounds or solvents are mostly non-polar in nature. And it is a thumb rule that like-dissolves-like.
Thus they dissolve covalent molecules like anhydrous aluminum chloride.
Anhydrous magnesium chloride is an ionic compound that tends to interact with a polar solvent but not in a non-polar solvent such as organic solvents.
Anhydrous aluminum chloride is fairly soluble in the organic solvent while anhydrous magnesium chloride is insoluble because anhydrous aluminum chloride is covalent whereas anhydrous magnesium chloride is ionic.

A balloon full of air has a volume of 1.00L at a temperature of 23 °C. What is the balloon's volume at 33°C?
Answer:1.03L
How do I solve this?
Answers
Answer:
V2= 1.03L
Explanation:
Start off with what you are given.
V^1: 1.00L
T^1: 23°C
V^2?
T^2: 33°C
If you know your gas laws, you have to utilise a certain gas law called Charles' Law:
V^1/T^1 = V^2/T^2
Remember to convert Celsius values to Kelvin whenever you are dealing with gas problems. This can be done by adding 273 to whatever value in Celsius you have.
(23+273 = 296) (33+273 = 306)
Multiply crisscross
1.00/296= V^2/306
296V^2 = 306
Dividing both sides by 296 to isolate V2, we get
306/296 = 1.0337837837837837837837837837838
V2= 1.03L
The pressure 15.0 m under water is 248 kPa.
What is this pressure in torr
Answers
Answer:
1860 torr
Explanation:
In order to convert from kPa to torr, we are going to use the following conversion factor:
1 kPa = 7.5 torrNow we multiply 248 kPa with this factor so that the kPa units cancel each other and only the torr units remain:
248 kPa * [tex]\frac{7.5torr}{1kPa}[/tex] = 1860 torrThis means that the answer is 1860 torr.

A balloon is filled with 30L of helium gas at 1atm.What is the volume when balloon rises to an attitude where the pressure is only 0.25 atm?
Answers
Answer:
[tex]V_2=120L[/tex]
Explanation:
Hello!
In this case, since Helium is undergoing a volume-pressure change, according the Boyle's law, we infer the following equation is used:
[tex]P_1V_1=P_2V_2[/tex]
Thus, since we are not given the volume at 0.25 atm, we can solve for V2 to do so:
[tex]V_2=\frac{P_1V_1}{P_2}[/tex]
Thus, we plug in to obtain:
[tex]V_2=\frac{1atm*30L}{0.25atm}=120L[/tex]
Best regards!
The final volume of the balloon at the given altitude is 120 L.
The given parameters;
initial volume of the balloon, V₁ = 30 Linitial pressure, P₁ = 1 atmfinal pressure of the balloon, P₂ = 0.25 atmThe final volume of the balloon at the given altitude is calculated by applying Boyles law as follows;
[tex]P_1 V_1 = P_2 V_2\\\\V_2 = \frac{P_1V_1}{P_2} \\\\V_2 = \frac{30 \times 1 }{0.25} \\\\V_2 = 120 \ L[/tex]
Thus, the final volume of the balloon at the given altitude is 120 L.

What is the limiting reactant if you are using 25.0 grams of phosphorus and 50.0 grams of oxygen?
A.) O2
B.) P4
C.) P4O10
D.) P4O2
Answers
Answer:
B.) P4
Explanation:
Step 1: Convert 25.0 grams of phosphorus into moles of phosphorous:
25 g P4 x 1 mol P4/123.90 g P4 = 0.202 mol P4
Step 2: Convert 0.202 mol P4 into moles of O2 using their stoichiometric ratios:
0.202 mol P4 x 5 mol O2/1 mol P4 = 1.01 mol O2
Step 3: Convert 1.01 mol O2 into grams of O2:
1.01 mol O2 x 31.98 g O2/1 mol O2 = 32.3 g O2
Because 25.0 grams of phosphorous only needs 32.3 grams of oxygen to react, phosphorous will be the limiting reactant, as after the 25.0 grams of phosphorous is used up, there will still be 17.7 grams of oxygen leftover (excess reactant).
Because the reaction cannot occur without more phosphorous to react with the 17.7 grams of oxygen remaining, P4 is the limiting reactant.
Answer: B.) P4
Explanation:
Step 1: Convert 25.0 grams of phosphorus into moles of phosphorous:25 g P4 x 1 mol P4/123.90 g P4 = 0.202 mol P4

Step 3: Convert 1.01 mol O2 into grams of O2:1.01 mol O2 x 31.98 g O2/1 mol O2 = 32.3 g O2
Because 25.0 grams of phosphorous only needs 32.3 grams of oxygen to react, phosphorous will be the limiting reactant, as after the 25.0 grams of phosphorous is used up, there will still be 17.7 grams of oxygen leftover (excess reactant).

An antacid tablet with an active ingredient of CaCO3 was dissolved in 50.0 mL of 0.300 M HCl. When this solution was titrated with 0.300 M sodium hydroxide, 32.47 mL was required to reach the end point. Determine the mass (in grams) of calcium carbonate in the tablet. Molar Mass of CaCO3
Answers
Answer:
Explanation:
mole of HCl remaining after reaction with CaCO₃
= .3 M of NaOH of 32.47 mL
= .3 x .03247 moles
= .009741 moles
Initial HCl taken = .3 x .005 moles = .0015 moles
Moles of HCl reacted with CaCO₃
= .009741 - .0015 = .008241 moles
CaCO₃ + 2HCl = CaCl₂ + CO₂ + H₂O .
1 mole 2 moles
2 moles of HCl reacts with 1 mole of CaCO₃
.008241 moles of HCl reacts with .5 x .008241 moles of CaCO₃
CaCO₃ reacted with HCl = .5 x .008241 = .00412 moles
the mass (in grams) of calcium carbonate in the tablet
= .00412 x 100 = .412 grams . ( molar mass of calcium carbonate = 100 )
We have that the mass (in grams) of calcium carbonate in the tablet is mathematically given as
mass of CaCO₃= 0.412 grams
The mass (in grams) of calcium carbonate in the tabletQuestion Parameters:
An antacid tablet with an active ingredient of CaCO3 was dissolved in 50.0 mL of 0.300 M HCl. titrated with 0.300 M sodium hydroxide, 32.47 mL was required to reach the end point.Generally the equation for the mole of HCl is mathematically given as
mole of HCl = 0.3 M of NaOH of 32.47 mL
mole of HCl= 0.3 x 0.03247 moles
mole of HCl= 0.009741 moles
Therefore
Initial HCl taken = 0.3 x 0.005 moles
Initial HCl taken= 0.0015 moles
Moles of HCl reacted with CaCO₃
M_{hcl}= 0.009741 - .0015
M_{hcl}= .008241 moles
The Chemical Equation
CaCO₃ + 2HCl = CaCl₂ + CO₂ + H₂O .
Therefore, CaCO₃ reacted with HCl is
CaCO₃ reacted with HCl= 0.5 x 0.008241
CaCO₃ reacted with HCl= .00412 moles
Hence,the mass of CaCO₃ is
mass of CaCO₃ = 0.00412 x 100
mass of CaCO₃= 0.412 grams
