Answer: A. 11.15
Explanation:
The pH of a solution is given by the formular; pH = -log [H+].
pH = - log [ 7.0 x 10 ∧-12]
= 12 - log 7
= 12 - 0.845
= 11.15
Answer:
All I know is these things hope they help u.
False. carbon-carbon bonds that share 2 pairs of electrons are double bonds. An unsaturated hydrocarbon isnt necessary to only have double bonds. they can also have single bonds or triple bonds.
Answer:
5% is the percent error
Explanation:
Percent error is defined as the 100 times the ratio of absolute value of the difference between the measurement and the theoretical value and the theoretical value, that is:
In the problem, theoretical value is 5.80g and the measurement is 5.51g:
% =
<h3>5% is the percent error</h3>
Answer:
False.
Explanation:
Scientific theories and hypothesis are all tentative. Science tries to prove something is either true of false and come up with answers (as much as we can) for many problems. Sometimes they are made based on limited data or information. Over the years, we come up with need findings discoveries which are able to give us more information and give us better answers. There have been a couple of scientific laws which had to be completely revised or discarded after new observations. An example of this would be the Laws of Thermodynamics. A couple of the laws have been changed over the decades after scientists made new disoveries and observations.
