First write out the eqn, and balance it.
next, take 12.8g/mr of aluminium
this will give u the mols of aluminium
next, take the ratio of HCL and Al, compare and find the mols of HCL.
take the mols of HCL/mr of HCL to give u mass

Naproxen is known to be a weak acid. In order to calculate
its ka and pka, use the equation of getting the ph of weak acid which is ph=
-1/2 log [(Ka)(Mwa)]. The Ka value is 3.18x10^-5. The pKa can be obtained
through pKa = - log Ka. The pKa is 4.5.
4) would be your correct answer
Answer:
they are indeed very strong
Answer:
True
Explanation:
If a question cannot be tested and observed, it cannot simply be answered by science.
Science works with observable and testable ideas and not on metaphysics.
- Science presents a methodical approach into investigating phenomenon and answering likely questions in a logical manner.
- The body of facts and data gathered through observations and tests are used to ramify the conclusion of a scientific study.
- Without such, it is impossible to do the work of science.
