Answer:

6.208 mol

Explanation:

Mass of Bromine Liquid = 496g

Number of moles = ?

Relationship between number of moles and mass is given as;

Number of moles = Mass / Molar mass

Molar mass of Bromine = 79.9g

Number of moles = 496 / 79.9 = 6.208 mol

Answer:

becous thear are two products

Explanation:

The statement is "Because there is only on reactant."

Reactant are raw materials that react with one another and form products.

What is decomposition reaction?

A decomposition reaction can be defined as a chemical reaction in which one reactant breaks into two or more product.

Hence the correct explanation about the reaction is "because there is only one reactant"

Answer:

B. Indicator

Explanation:

An indicator is used to determine whether an acid or alkali has been added to a solution.

An acid or alkali changes the hydrogen ion concentration in solution. This is indicated by the pH of the solution after which the acid or alkali has been added.

The solubility of lead chromate : s= 5.29 x 10⁻⁷ mol/L

Given

Ksp  for PbCl,=2.8x10*-13 mole/dmº

PbCrO4

Required

The solubility

Solution

P b C r O ₄ ( s ) ⇌ P b²⁺( a q) +C r O ₄ ⁻²( a q )

s                     s               s

s= solubility

Ksp P b C r O ₄  = s²

K s p  = [ P b ²⁺] [C r O ₄ ⁻² ]= 2.8x10⁻¹³

s = √2.8x10⁻¹³

s= 5.29 x 10⁻⁷ mol/L

Answer:

pOH = 8.41

Explanation:

From the question given above, we obtained the following information:

Concentration of Hydrogen ion [H⁺] = 2.6×10¯⁶ M

pOH =?

Next, we shall determine the pH of the solution. This can be obtained as follow:

Concentration of Hydrogen ion [H⁺] = 2.6×10¯⁶ M

pH =?

pH = – Log [H⁺]

pH = – Log (2.6×10¯⁶)

pH = 5.59

Finally, we shall determine the pOH of the solution. This can be obtained as follow:

pH = 5.59

pOH =?

pH + pOH = 14

5.59 + pOH = 14

Collect like terms

pOH = 14 – 5.59

pOH = 8.41

Therefore, the pOH of the solution is 8.41

0.042 moles of Hydrogen evolved

Given

I = 1.5 A

t = 1.5 hr = 5400 s

Required

Number of Hydrogen evolved

Solution

Electrolysis of water ⇒ decomposition reaction of water into Oxygen and Hydrogen gas.

Cathode(reduction-negative pole) : 2H₂O(l)+2e⁻ ⇒ H₂(g)+2OH⁻(aq)

Anode(oxidation-positive pole) : 2H₂O(l)⇒O₂(g)+4H⁻(aq)+4e⁻

Total reaction : 2H₂O(l)⇒2H₂(g)+O₂(g)

So at the cathode H₂ gas is produced

Faraday : 1 mole of electrons (e⁻) contains a charge of 96,500 C

[tex]\tt mol~e^-=\dfrac{Q}{96500}[/tex]

Q = i.t

Q = 1.5 x 5400

Q = 8100 C

mol e⁻ = 8100 : 96500 = 0.084

From equation at cathode , mol ratio e⁻ : H₂ = 2 : 1, so mol H₂ = 0.042

Explanation:

By having 2 water molecules, we reach the 4 H atoms and 3 O atoms that are present on the left side. We don't add any other coefficients because we already have enough N atoms and we don't have to manipulate the left side at all.

Answer:

a. True

b. True

c. False

d. True

Explanation:

a). A a very low substrate concentration , [tex]$S<< Km$[/tex]. Thus according to the Machaelis-Menten equation becomes

[tex]$V_0 = \frac{V_{max} \times [S]}{Km}$[/tex]

Here since the [tex]$V_0$[/tex] varies directly to the substrate concentration [S], the initial velocity is lower than the maximal velocity. Thus option  (a) is true.

b). The Michaelis -Menten kinetics equation states that :

   [tex]$V_0 = \frac{V_{max} \times [S]}{Km+[S]}$[/tex]

  Here the initial velocity changes directly with the substrate concentration as [tex]$V_0$[/tex] is directly proportional to [S]. But [tex]$V_{max}$[/tex] is same for any particular concentration of the enzymes. Thus, option (b) is true.

c). As the substrate concentration increases, the initial velocity also increases. Thus option (c) is false.

d). Option (d) explains the procedures to estimate the initial velocity which is correct. Thus, option (d) is true.

When waves travel from one medium to another, they interact. When waves hit a new medium, they may bend or spread out instead of bouncing back like an echo. These three interactions of waves with matter are known as reflection, refraction, and diffraction.

Interactions include reflection, refraction, and diffraction. An example of wave reflection is an echo. Refraction occurs when waves bend at an angle as they enter a new medium. When waves spread out as they travel through an opening in an obstacle, this is referred to as diffraction.

When two or more waves collide, they interact with one another. Wave interference is the interaction of waves with other waves. When two waves traveling in opposite directions collide, wave interference occurs.

Thus, the interactions of waves with matter are known as reflection, refraction, and diffraction.

By definition, the correct answer is option 5. A barium atom (Ba) would form its most stable ion by the loss of two electrons.

An ionic bond is produced between metallic and non-metallic atoms, where electrons are completely transferred from one atom to another. During this process, one atom loses electrons and another one gains them, forming ions. Usually, the metal gives up its electrons forming a cation to the nonmetal element, which forms an anion.

In other words, anions are negatively charged ions and are formed when metals gain electrons. Cations are positively charged ions and are formed when a metal loses electrons.

The electrostatic attraction between positives and negatives attracts the particles to each other and creates an ionic compound.

A barium (Ba) atom is a metal, so it loses 2 electrons to comply with the octet rule, which states that the atoms of the elements bond together in an attempt to complete their valence shell, leaving the atom stable with 8 electrons in its last shell and thus be stable.

Finally, the correct answer is option 5. A barium atom (Ba) would form its most stable ion by the loss of two electrons.
