Answer:

The correct answer is 0.206 moles

Explanation:

According to the given scenario, the calculation of the number of moles of ammonium chloride is available in the resulting solution is given below:

Given that

Amount of [tex]NH_4Cl[/tex] is 11.0 grams

And, the volume is 235 mL

Now the molar mass of [tex]NH_4Cl[/tex] is 53.49g/mol

So, the number of moles presented is

= 11.0 ÷ 53.49

= 0.206 moles

hence, the number of moles of ammonium chloride are available in the resulting solution is 0.206 moles

Answer:

Lipids are fatty, waxlike molecules found in the human body and other organisms. They serve several different roles in the body, including fueling it, storing energy for the future, sending signals through the body and being a constituent of cell membranes, which hold cells together.

Explanation:

In biology and biochemistry, a lipid is a macrobiomolecule that is soluble in nonpolar solvents. Non-polar solvents are typically hydrocarbons used to dissolve other naturally occurring hydrocarbon lipid molecules that do not dissolve in water, including fatty acids, waxes, sterols, fat-soluble vitamins, monoglycerides, diglycerides, triglycerides, and phospholipids.

Answer:

Two, KCl and PbCl₂.

Explanation:

Hello!

In this case, since the addition of chloride ions promote the following three ionic reactions:

[tex]Ag^+(aq)+Cl^-(aq)\rightleftharpoons AgCl(s)\\\\K^+(aq)+Cl^-(aq)\rightleftharpoons KCl(aq)\\\\Pb^{2+}(aq)+Cl^-(aq)\rightleftharpoons PbCl_2(s)[/tex]

We can infer that both silver chloride and lead (II) chloride are precipitated products as their Ksp are 6.56x10⁻⁴ and 1.59x10⁻⁵ respectively, which means they are merely soluble in water.

Best regards!

Silver chloride (AgCl), Potassium chloride (KCl) and Lead chloride (Pb2Cl) are produced when added the solution of chlorine.

If a chloride solution is added in the container which contains aqueous mixture that comprise of Ag+ , K+ , and Pb2+ cations, three different solid precipitate will be formed. Silver chloride (AgCl), Potassium chloride (KCl) and Lead chloride (Pb2Cl) are the three solid precipitate that will formed when the chlorine in added to the solution.

The chlorine is an anion which reacts with all three Ag+, K+ and Pb2+ cations produces Silver chloride (AgCl), Potassium chloride (KCl) and Lead chloride (Pb2Cl) respectively so we can conclude that Silver chloride (AgCl), Potassium chloride (KCl) and Lead chloride (Pb2Cl) are produced when added the solution of chlorine.

Explanation:

The volume of H₂O = 5 L

Further explanation

Given

5L of H₂ and 3L O₂

Reaction

2H₂ (g) + O₂(g) ⇒2H₂O(g)

Required

The volume of H₂O

Solution

Avogadro's hypothesis:

In the same T,P and V, the gas contains the same number of molecules

So the ratio of gas volume will be equal to the ratio of gas moles

mol H₂ = 5, mol O₂ = 3

Find limiting reactants

From equation, mol ratio H₂ : O₂ = 2 : 1, so :

[tex]\tt H_2\div O_2=\dfrac{mol~H_2}{coefficient}\div \dfrac{mol~O_2}{coefficient}\\\\=\dfrac{5}{2}\div \dfrac{3}{1}=2.5\div 3\rightarrow H_2~limiting~reactant(smaller~ratio)[/tex]

Find volume H₂O

mol H₂O based on mol H₂, and from equation mol ratio H₂ : H₂O=2 : 2, so mol H₂O = 5 mol and the volume also 5 L

Answer:

The correct answer is 0.3088 L.

Explanation:

The reaction will be,

Mg + 2 HCl = MgCl2 + H2

The moles can be determined by using the formula,

Moles = Given mass/Molecular mass

Based on the given information, the weight of Mg is 0.0300 g, and the molecular mass of Mg is 24.30 g/mol.

Now putting the values we get,

Moles = 0.300 g/24.30 g/mol = 0.01235 mol

From the reaction, it can be seen that 1 mol of Mg produces 1 mol of H2 gas then 0.01235 mol of Mg will produce 0.1235 mol of H2.

The volume of hydrogen gas produced can be determined by using the gas law equation,

V = nRT/P

Here V is volume in L, P is the pressure in atm, R is the gas constant, which is 0.08206, and T is temperature in Kelvin, 21.8 degree C = 21.8 + 273.15 = 294.95 K.

P = 735.6 torr = 735.6 * 0.00132 atm = 0.9679 atm

V = 0.1235 mol * 0.08206 atm L/mol/K * 294.95 K/0.9679 atm

V = 0.3088 L

Hence, the volume of hydrogen gas produced is 0.3088 L.

The ground state electron configuration of ground state gaseous neutral antimony is [Kr].4d10.5s2.5p3

Answer: =0.26J/gC

Explanation:

From the question, we are informed that the solid requires 124 J of heat to raise the temperature of 95.5 g of substance from 20.0 to 25.0. The specific heat required would be:

Specific heat = energy required / (temperature difference × mass )

=124J / (5C × 95g)

= 124J / 495gC

=0.26J/gC

Density Formula: Density = Mass / Volume

Answer:

c. 0.750 atm.

Explanation:

Hello!

In this case, since the two vessels have different volume, we can see that the gas is initially at 3.00 atm into the 1.00-L vessel, but next, it is allowed to move towards the 3.00-L vessel, meaning that the final volume wherein the gas is located, is 4.00 L; therefore, we use the Boyle's law to compute the final pressure:

[tex]P_2V_2=P_1V_1\\\\P_2=\frac{P_1V_1}{V_2} \\\\P_2=\frac{3.00atm*1.00L}{4.00L}\\\\P_2=0.750atm[/tex]

Therefore the answer is c. 0.750 atm.

D) a pair of diastereomers

Explanation:

The reaction is commonly referred to as the oxomercuration of alkenes. It involves the reaction of an alkene with mercury (II) acetate, then sodium borohydride, NaBH4. The product is an alkanol.

The mechanism of this reaction is shown in the image attached. We can see that the product contains two chiral centers. The reaction yields a pair of diastereomers.

There is a law called conservation of energy which states that energy can neither be created nor be destroyed. It can be only transferred from one form to another form. Therefore, the correct option is option A.

What is energy transfer in thermodynamics?

Energy transfer is a phenomenon in which energy transfer from one matter to another matter. Energy can be transferred in two forms that are by doing work or by transferring heat.

To move any object energy is required so work has to be done by the gas to the piston. Heat can be transferred by three ways conduction, convention and radiation. In conduction, when two object are in direct contact, transfer of molecules takes place. Wind blowing at 3 km/h has kinetic energy. Anything that move possess kinetic energy.

Therefore, the correct option is option A.

The question is incomplete, the complete question is;

Predict the concentration if a 0.5 M solution, with a volume of 500 mL, is diluted to a volume of 1 liter. Show the calculation of this concentration, include units in all your work.

Answer:

0.25 M

Explanation:

From;

C1V1 =C2V2

C1= initial concentration = 0.5 M

C2 = final concentration = the unknown

V1 = initial volume = 500 ml

V2 = final volume = 1 litre = 1000 ml

substituting values;

0.5 * 500 = C2 * 1000

C2 = 0.5 * 500/1000

C2 = 0.25 M

Answer:

24 molecules of phosphorus trichloride can be formed

Explanation:

Based on the equation:

P4(s) + 6Cl2(g) → 4PCl3

1 mole of P4 reacts with 6 moles of Cl2 to produce 4 moles of PCl3.

When 10 molecules of P4 react, 60 molecules of Chlorine are needed. As there are just 36 molecules, Cl2 is limiting reactant.

If 36 molecules of chlorine are added, molecules of PCl3 produced are:

36 molecules Cl2 * (4 PCl3 / 6 Cl2) =

24 molecules of phosphorus trichloride can be formed

The maximum amount of phosphorus trichloride that can be formed from 10 molecules of P4 and 36 molecules of chlorine would be 24 molecules.

From the balanced equation of the reaction, the mole ratio of P4 to Cl2 to PCl3 is 1:6:4.

Thus, for every 1 molecule of P4, 6 molecules of Cl2 would be required.

In the same vein, 10 molecules of P4 will require 60 molecules of Cl2. But there are just 36 molecules of Cl2. Thus, Cl2 is a limiting reactant.

The mole ratio of Cl2 to PCl3 is 6:4 or 3:2.

Hence, with 36 molecules of Cl2, the maximum amount of PCl3 that can be formed would be:

36 x 2/3 = 24 molecules.
