What happens when K2O dissolves in water?

Chemistry
1 answer:
Mkey [24]2 years ago
7 0
Firstly 

the overall reaction is k2o + H2O --------> 2KOH 

That above is the molecular equation 

net ionic equation, as the specatator ion, the one that is not involved in the reation is in fact K+ 

THE NET IONIC EQUATION is therefore 

O2- + H2O ------>2OH- 

Acid is defined as the proton donar, in otherwards the one that donated a positve charge, here , the water donated a postive H+ ion to the O2-, SO the h2o is the acid while the O2- is the base. 

Acid : h2o 

Spectator ion : k+, pottasium ion

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

dusya [7]

Renal failure is the new diagnosis that the provider would prompt to discontinue a PRN order for magnesium hydroxide.

<h3>What is Renal failure?</h3>

Renal failure is a special condition where the person is unable to manage the function of the kidney organ.

The magnesium hydroxide may cause renal failure because this salt must be eliminated by the kidney and therefore it may trigger health complications.

In conclusion, renal failure is the new diagnosis that the provider would prompt to discontinue a PRN order for magnesium hydroxide.
