<em>Answer:</em>
- As concentration is best represented by large bracket like this [x]. So
[K2CrO4] = 1.75 M
Or
[K2CrO4] = 1.75 mole per litre.
<em>Explantion:</em>
- Molarity = No. of moles × 1/ volume (litre)
Answer:earth quakes

Answer:
Isotopes – caused by varying numbers of neutrons in an element – have many practical uses in our society. ... In geology and archaeology, radioactive isotopes are used to determine the age of a sample while hydrologists can use isotope signatures to distinguish between different groundwater types.
Explanation:
Google. It's a magical place.
Answer is A) Al4C3 + 3H2O -> CH4 + 4Al(OH)3
One the left side there are 3 carbon atoms, or moles of carbon, and on the write side there is only one.
In order to solve these problems, count the number of atoms on each side and make sure that for each element, the number of atoms are equal.
For example, for the last problem, we have 1 zinc atom on each sidde, two hydrogen atoms, and two chlorine atoms.
