Answer:

Option C. Decomposition

Explanation:

To know which option is correct, it is important we know what is a single displacement reaction, double displacement reaction and decomposition reaction.

A Single displacement reaction can be defined as a reaction in which a single element is replaced by another element in a compound.

A double displacement reaction is a reaction involving the exchange of ions of two parts of ionic compounds to form two different compounds.

A decomposition reaction is a reaction in which a compound splits into two or more simpler compound or element.

Bearing the above definitions in mind and considering the question given above, we can conclude that the reaction given in the question above is a decomposition reaction since the compound (NH₄OH) splits into two different compound (NH₃ and H₂O)

Answer:

The $K_{m}$ of a substrate will be "10 μM".

Explanation:

The given values are:

$E_{t} = 20 \ nM$

$[Substract] = 40 \ \mu M$

$K_{cat}=600 \ s^{-1}$

Reaction velocity, $Vo=9.6 \ \mu M s^{-1}$

As we know,

⇒ $Vo=\frac{K_{cat}[E_{t}][S]}{K_{m}+[S]}$

On putting the estimated values, we get

⇒ $9.6=\frac{600\times 20\times 10^{-3}\times 40}{K_{m}+40}$

⇒ $K_{m}+40=\frac{600\times 20\times 10^{-3}\times 40}{9.6}$

⇒ $K_{m}+40=50$

On subtracting "40" from both sides, we get

⇒ $K_{m}+40-40=50-40$

⇒ $K_{m}=10 \ \mu M$

When KNO3 dissolved in water, what is the intermolecular attraction between NO3 ions

Snezhnost [94]

Ion-dipole forces

H2O has hydrogen bonding, which is a form of dipole-dipole forces, and NO3- is an ion, so the intermolecular attraction is ion-dipole.

A metallurgist has one alloy containing 21% aluminum and another containing 42% aluminum. how many pounds of each alloy must he

Naily [24]

Answer is: 7.8 lb of 21% aluminum and 33.2 ib of 42% aluminum.

ω₁ = 21% ÷ 100% = 0.21.
ω₂ = 42% ÷ 100% = 0.42.
ω₃ = 38% ÷ 100% = 0.38.
m₁ = ?.

m₂ = ?.
m₃ = m₁ + m₂.
m₃ = 41 pounds.

m₁ = 41 lb - m₂.
ω₁ · m₁ + ω₂ ·m₂ = ω₃ · m₃.

0.21 · (41 lb - m₂) + 0.42 · m₂ = 0.38 · 41 lb.

8.61 lb - 0.21m₂ + 0.42m₂ = 15.58 lb.

0.21m₂ = 6.97 lb.

m₂ = 6.97 lb ÷ 0.21.

m₂ = 33.2 lb.

m₁ = 41 lb - 33.2 lb.

m₁ = 7.8 lb.
