[H+] for HClO(this is a weak acid so it requires an I.C.E. table to solve):
(I=initial amount. C=change in amount. E= amount at equilibrium.)
I.C.E. table
HClO. H2O. >>> H3O+ ClO4-
I. 0.100M. N/A. 0. 0
C. -x. N/A. +x. +x
E. 0.1-x. N/A. x. x.
(we don't consider water because it is not an aqueous solution)
ka=(x^2)/(0.1-x)
(2.9×10^-8)= (x^2)/(0.1-x)
(0.1-x)(2.9×10^-8) = x^2
(3.0×10^-9) - ((2.9×10^-8)x) = x^2
x^2+(2.9×10^-8)x-(3×10^-9)
a=1
b=(2.9×10^-8)
c= -(3×10^-9)
plug those values into the quadratic formula:
x= (-b +(√((b^2)-4ac))))/2a
I got x= 0.000053837
x= [H+] =0.000053837
[H+] for 0.100 M HClO4:
because HClO4 is a strong acid, it dissociates completely. Meaning that it's [H+] =0.1
Answer:
3.2 Calories
Explanation:
Here we will use a formula
Heat added in calories = Mass of glass x Increase in temperature x specific heat of glass
As we know that, specific heat is the amount of energy required to raise the temperature of one gram of any substance by 1°C. It has a constant value for every substance and for glass the specific heat is .16 calories/gm
Incorporating the values of mass (m), temperature(T) and specific heat (c) in formula.
calories (small calories) = l.0 g x 20 degrees x .16 calories/gm/°C
= 3.2 calories
Hope it helps:)
it´s actually Lithium and fluorine / Magnesium and Chlorine / Beryllium and Nitrogen
Answer:
2859 milliliters
Explanation:
Just move the decimal to the left and you get this as your answer
Formula : multiply the volume value by 1000
Hope this helps :)
The U-235 fission will produce krypton-92 and barium-141. And this process will also release huge amount energy. And U-235 also go through α decay model.
