Yes because look in the book dh
Answer:
Evaporate minerals are more soluble than calcite and quartz.
Explanation:
Evaporate minerals are the water soluble minerals which at higher concentration precipitate out and crystallized forming rocks.
example of chemicals present are:
chlorides and sulphates.
Quartz is silica (very less soluble, or insoluble)
Calcite is calcium carbonate, again an insoluble salt.
Thus
Evaporate minerals are more soluble than calcite and quartz.
<span>The solution to the problem is as follows:
125/58.69 = 2.12 mol
</span>
Therefore, there are 2.12 moles of <span>nickel (Ni) atoms are in 125 g Ni.

Answer:
21.9 g C
Explanation:
Fe₂O₃ + 3 C ⇒ 2 Fe + 3 CO
This is your chemical equation.
To find the grams of C required, first convert grams of Fe₂O₃ to moles using the molar mass (159.69 g/mol).
(97.1 g)/(159.69 g/mol) = 0.608 mol Fe₂O₃
Then, use the mole ratio between Fe₂O₃ and C to convert moles of Fe₂O₃ to moles of C. You can find the mole ratio by looking at the chemical equation.
(0.608 mol Fe₂O₃) × (3 mol Fe₂O₃/1 mol Fe₂O₃) = 1.824 mol C
You can then convert moles of C to grams using the molar mass (12.01 g/mol).
(1.824 mol) × (12.01 g/mol) = 21.9 g
