Answer:
Explanation:
Replication is crucial to science. Every time researcher find something surprising that has to do with science they replicate it.
Answer:
The answer is
<h2>14.50 cm³</h2>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula
From the question
mass of iron = 114 g
density = 7.86 g/cm³
The volume is
We have the final answer as
<h3>14.50 cm³</h3>
Hope this helps you
Answer:
Hi! In this case, the reactioncan be correctly balance according to this: 2Al(s) + 3CuSO4(aq) –> Al2(SO4)3(aq) + 3Cu(s).
Explanation:
In this particulary reaction,two semi-reactions happens.
One involving the metallic aluminum that suffers an oxidation reaction:
Al (s) -> Al3 + (aq) + 3e–
and another is a reduction reaction involving copper;
2e– + Cu2 + (aq) -> Cu (s)
Uranium is in the "f" block, because it's external electron configuration is
Answer:
We say that the solution is unsaturated.
Explanation:
If the salt solubility is 36 g in 0.1 L of water then we can dissolve 360 g of salt in 1 L of water.
Because the solution contains 200 g of salt in 1 L of water, the solution is unsaturated because more salt can be added until we reach the saturation point.
We call the solution dilute when we compare the concentration of a solution with the concentration of another solution, but here we do not compare different solutions.
