Answer:
one in a billion
Explanation:
We have it known that Pure water is entirely made up of H2O molecules. Just 1 in 10⁹, that is a billion molecules are ionized when it is at room temperature.
The Ionization of water has this chemical equation:
H2O <--> H+ + OH-
When At equilibrium and at room temperature, we have the rate of forward reaction and the backward reaction to be very fast such that no water molecule would eventually remain ionized.
Therefore our answer is roughly one in a billion water.
The ionization energy or ionization potential is - the energy required to remove an electron from an element in its gaseous state.
You subtract the number of protons from the mass number to get the number of neutrons.
SO2- It is polar because it has dipole moment.
CH2Cl2
PCl3
Answer:- Answer is 69.7 second.
Solution:- For solving problems based on first order equations is:
where, is the initial concentration and [A] is final concentration.
k is rate constant and t is the time.
It asks to calculate the time in which 30% of the substrate would be consumed. Let's say the initial amount of the substrate is 100 then 30 is used and remaining would be, 100 - 30 = 70
So, = 100
[A] = 70
t = ?
Let's plug in the values in the equation and solve it for t:
4.248 = -0.00512(t) + 4.605
4.248 - 4.605 = -0.00512(t)
-0.357 = -0.00512(t)
we have negative sign on both sides, so it is canceled out.
0.357 = 0.00512(t)
t = 69.7 seconds
So, it would take 69.7 seconds for 30% substrate to be consumed.
