16.00 grams of oxygen
since in one mole the mass would be the molecular mass, which is found on the periodic table
Answer:
14 moles of oxygen needed to produce 12 moles of H2O.
Explanation:
We are given that balance eqaution
We have to find number of moles of O2 needed to produce 12 moles of H2O.
From given equation
We can see that
6 moles of H2O produced by Oxygen =7 moles
1 mole of H2O produced by Oxygen=moles
12 moles of H2O produced by Oxygen=moles
12 moles of H2O produced by Oxygen=moles
12 moles of H2O produced by Oxygen=14 moles
Hence, 14 moles of oxygen needed to produce 12 moles of H2O.
Answer:
what it does to those around you.
Definitions needed:
pH = -log[H^+]
pOH = -log[OH^-]
pH + pOH = 14
[H^+]*[OH^-] = 10^-14
(a) [H+] = 3.0 10-13 M
[OH ‾ ] = _____ M
Acidic, Basic, or Neutral?
[H^+]*[OH^-] = 10^-14
[OH^-] = (10^-14)/[H^+]
[OH^-] = (10^-14)/(3.0 10-13 M) = 0.033 M
That's a high concentration of [OH^-], so the solution is basic
(b) [OH ‾ ] = 3.0 10-7 M
[H+] = ______M
Acidic, Basic, or Neutral?
[H^+]*[OH^-] = 10^-14
[H^+]* = (10^-14)/[OH^-]
[H^+]* = (10^-14)/(3.0 10-7 M) = 3.33 x 10^-8
That would be a slightly basic solution (pH just higher than 7).
A control sample serves as a sample used to eliminate errors or minimize them. Also, it is used to prevent the effect of one parameter which is not the subject being studied. For instance, in an adsorption experiment a control sample is always included wherein in a flask it only contains the adsorbate solution. The said sample is responsible for calculating how much of the adsorbate is being adsorbed on the sides of the flask.
