Why did scientists need to establish an international language for elements
Liono4ka [1.6K]
If they didn't, they wouldn't be able to communicate their findings effectively. An international language is especially important for elements because many elements have similar properties (e.g. some of the transition metals).

450g of chromium (III) sulfate reacts with excess potassium phosphate. How many grams of potassium sulfate will be produced? (AN
Oduvanchick [21]

Answer:

599.26 grams of potassium sulfate will be produced.

Explanation:

Cr_2(SO_4)_3(aq)+2K_3PO_4(aq)\rightarrow 2CrPO_4(s)+3K_2SO_4(aq)

Moles of chromium (III) sulfate = \frac{450 g}{392 g/mol}=1.1480 mol

According to reaction, 1 mole of chromium (III) sulfate gives 3 moles of potassium sulfate.

Then 1.1480 moles of chromium (III) sulfate will give:

\frac{3}{1}\times 1.1480 mol=3.4440 mol

Mass of 3.4440 moles of potassium sulfate:

= 3.4440 mol × 174 g/mol = 599.26 g

599.26 grams of potassium sulfate will be produced.
