Answer:- 
Solution:- percent ionization = 
where, 
is the equilibrium concentration of product ion and c is the initial concentration of the acid.
Let's plug in the values in the formula:
In general, the acid is represented as HA, the ice table is shown as:
I 0.10 0 0
C -X +X +X
E (0.10 - X) X X
where X is the change in concentration that we already have find out using percentage ionization formula.
![Ka=\frac{[H^+][A^-]}{[HA]}](https://tex.z-dn.net/?f=Ka%3D%5Cfrac%7B%5BH%5E%2B%5D%5BA%5E-%5D%7D%7B%5BHA%5D%7D)
Let's plug in the values in it:
0.003 is almost negligible as compared to 0.10, so (0.10 - 0.003) could be taken as 0.10.
Second choice is the right one.
Answer:
1 makes the most sense
Explanation:
There is no way blood pressure will be decreased especially if your ventricles are erratically contracting for a long period of time. So 3 and 4 are out. And you said number 2 is wrong so my finally answer is 1.
It's a weak base bacause H C N is weak
Answer:
Certain things we think of as hard work, such as writing an exam or carrying a heavy load on level ground, are not work as defined by a scientist. The scientific definition of work reveals its relationship to energy—whenever work is done, energy is transferred.
For work, in the scientific sense, to be done, a force must be exerted and there must be motion or displacement in the direction of the force.
Answer:
Heat required = 13,325 calories or 55.75 KJ.
Explanation:
To convert a water to steam at 100 degree celsius to vapor, we have to give latent heat of vaporization to water
Which equals ,
Q = mL,
Where, m is the mass of water present
L = specific latent heat of vaporization
Here , m= 25 gram
L equals to 533 calories (or 2230 Joules)
So, Q = 25×533 = 13,325 Calories
Or , Q = 55,750 Joules = 55.75 KJ
so, Heat required = 13,325 calories or 55.75 KJ.
