Answer:

1.44 x 10²⁵ ions of Na⁺

Explanation:

Given parameters:

Mass of NaCl  = 1.4kg  = 1400g

Unknown:

Number of ions of sodium  = ?

Solution:

The compound NaCl in ionic form can be written as;

      NaCl →  Na⁺ + Cl⁻

In 1 mole of NaCl we have 1 mole of sodium ions

 Now, let us find the number of moles in NaCl;

  Number of moles  = [tex]\frac{mass}{molar mass}[/tex]  

    Molar mass of NaCl  = 23 + 35.5 = 58.5g/mol

Number of moles  =  [tex]\frac{1400}{58.5}[/tex]     = 23.93mol

 So;

   Since 1 mole of NaCl gives 1 mole of Na⁺  

    In 23.93 mole of NaCl will give 23.93 mole of Na⁺

1 mole of a substance  = 6.02 x 10²³ ions of a substance

  23.93 mole of a substance  =  6.02 x 10²³ x  23.93

                                                   = 1.44 x 10²⁵ ions of Na⁺

Solution properties are the properties of a solution that don't depend on the type of solute but only on the concentration of the solute.  

Solutions from volatile substances have a higher boiling point and lower freezing points than the solvent  

For freezing point can be formulated

[tex]\tt \Delta T_f=K_f.m[/tex]  

K = molal freezing point constant  

m = molal solution  

A solution with a freezing point of -5.8 ∘C

[tex]\tt \Delta T_f=T_f~solvent-T_f~solution=0-(-5.8)=5.8[/tex]

Answer:

Percent yield = 17%

Explanation:

Given data:

Actual yield of lithium chloride = 6.0 g

Theoretical yield of lithium chloride = 35.4 g

Percent yield = ?

Solution:

Formula:

Percent yield = (actual yield / theoretical yield )× 100

Now we will put the values in formula.

Percent yield = (6.0 g/ 35.4 g)× 100

Percent yield = 0.17 × 100

Percent yield = 17%

Answer:

4 calcium ions and 4 sulfide ions.

Explanation:

In a face centered unit cell, 8 corners of the unit cell are occupied by 8 atoms. Each corner is 1/8 of a cell. In addition it has 6 atoms in the face of the lattice, which is 1/2 of a cell. (1/8 * 8) + (1/2 * 6) = 4. CaS has a 1:1 ratio. Therefore, they each have 4 ions.

Each cubic unit cell contains FOUR (4) calcium ions in octahedral holes and FOUR (4) sulfide ions at the lattice points.

In conclusion, each cubic unit cell contains FOUR (4) calcium ions in octahedral holes and FOUR (4) sulfide ions at the lattice points.

Answer:

Kindly check the explanation section.

Explanation:

Hydrogen in the periodic chart/table is the first element on the periodic table with binding energy of 0.000± 0.0000 keV, Isotopic mass of 1.007825 u, one or single proton and a spin value of half(1/2).

The first thing to note for the fact that hydrogen's sublevels within a principal level does not split into seperate or different energies is that THERE IS A VACANT GROUND STATE IN HYDROGEN ATOM. With this, it makes it impossible for the electrons that are inside to get infiltrated which is the case with the atoms with multielectron.

NB: Penetration is done by electrons outside.

Answer:

0.007756M KHP; 0.0009695 moles NaOH reacts; 0.03488M NaOH.

Explanation:

Potassium hydrogen phthalate, KHP, is a salt used as standard to determine concentration of basic solutions as NaOH solutions.

To find molarity of the KHP solution we need to convert mass of KHP to moles and divide this in 125mL = 0.125L:

Moles KHP -Molar mass: 204.22g/mol-:

0.198g * (1mol / 204.22g) = 0.0009695 moles KHP

Molarity:

0.0009695 moles KHP / 0.125L = 0.007756M KHP

NaOH reacts with KHP as follows:

NaOH + KHP → Na⁺ + KP⁻ + H₂O

That means 1 mole of NaOH reacts per mole of KHP, that means moles of NaOH that reacts are = Moles of KHP added:

0.0009695 moles NaOH reacts

In 27.80mL = 0.02780L the NaOH was contained. Molarity is:

0.0009695 moles NaOH / 0.02780L =

0.03488M NaOH

Moles of NaOH added will be "0.034".

According to the question,

→ [tex]Molarity = \frac{Number \ of \ moles}{Volume}[/tex]

By substituting the values, we get

                  [tex]= \frac{0.198}{204}\times \frac{1000}{125}[/tex]

                  [tex]= 0.0077 \ M[/tex]

Let,

Now,

→            [tex]M_1 V_1 = M_2 V_2[/tex]

→ [tex]0.0077\times 125=M_2\times 27.8[/tex]

→                [tex]M_2 = 0.034 \ moles[/tex]

Thus the above answer is appropriate.

The structures of the starting materials 2‑methylhept‑3‑yne can be seen in the diagram attached below. We will also notice the role of NaNH₂ which acts as a strong base and whose function is to extract acidic proton and form an alkyne as a product.

The reaction with NaNH₂ yields acetylide ion which is then reacted with a straight-chain alkyl halide to form an extended carbon chain.

CHECK THE DIAGRAM BELOW.

The reaction order for the following conditions are:

a. two

b. two

Reaction order is the number of reactants, whose concentration affects the reaction rate.

The reaction order can be determined by adding the exponents of each reactant.

The rate equation is [tex]v^0 = k[A]^x + k[B]^y[/tex]

The first-order reaction is in which the reaction is dependent on one variable concentration.

The second-order reaction is that in which the reaction is dependent upon the concentration of two variables.

Explanation:  The speed is distance divided by time

distance between start-point and end-point = 100 meters

time to cover the distance  =  5 minutes

Answer:

Volume of water added = 148.4 mL

Explanation:

Given data:

Initial volume = 424 mL

Initial molarity = 0.189 M

Final molarity = 0.140 M

Volume of water added = ?

Solution:

Formula:

M₁V₁  =   M₂V₂

0.189 M×424 mL = 0.140 M×V₂

V₂ = 0.189 M×424 mL /0.140 M

V₂ = 80.136 M.mL / 0.140 M

V₂ = 572.4 mL

Final volume of solution is  572.4 mL.

Volume of water added = Final volume - initial volume

Volume of water added = 572.4 mL - 424 mL

Volume of water added = 148.4 mL
