5. Balance the following reactions using either the oxidation number method or the half-reaction

Chemistry
1 answer:
stich3 [128]2 years ago
7 0

The balanced reaction equations are;

a) 4 NaClO + H2S → 4 NaCl + H2SO4

b)6Ce^4+ + I^– + 6OH^– → 6 Ce^3+ + IO3^– + 3H2O

<h3>What is a balanced redox reaction?</h3>

A redox reaction is said to be balanced when the number of electrons gained is equal to the number of electrons lost.

Let us now write the balanced reaction equations one after the other. Thus;

a) 4 NaClO + H2S → 4 NaCl + H2SO4

b)6Ce^4+ + I^– + 6OH^– → 6 Ce^3+ + IO3^– + 3H2O

A gas at STP has a volume of 1.00 L. If the pressure is doubled and the temperature remains constant, what is the news of the ga
4vir4ik [10]

Answer: PV = nRT

A gas at STP... This means that the temperature is 0°C and pressure is 1 atm.

R is the gas constant which is 0.08206 L*atm/(K*mol)

Rearranging for volume

V = nRT/P

The temperature and number of moles are held constant. This means that this uses Boyle's Law. (The ideal gas law could be manipulated to give us this result when T and n are held constant.)

PV = k

where k is a constant.

This means that

P₁V₁ = k = P₂V₂

P₁V₁ = P₂V₂

(1 atm) * (1 L) = (2 atm) * V₂

V₂ = 0.5 L

The new volume of the gas is 0.5 L.

A K+ ion is similar to a Cl– ion in that they both have the same A) nuclear charge B) number of electrons C) atomic number D) nu
pshichka [43]

Answer:

B) number of electrons

Explanation:

The two species:

          K+   and Cl- have the same number of electrons.

A neutral atom of K has 19 electrons

A neutral atom of Cl has 17 electrons

Now,

 To form K+, K will have to lose an electron and then the number of electrons becomes 18

To form Cl-, Cl will have to gain an electrons and then the number of electrons becomes 18

So, therefore, the number of electrons on both species is 18
