Answer:
Arsenic
Explanation:
This is because it has atomic number 33
Answer:
please mark my answer brainliest
Explanation:
according to the formula...
density =mass/ volume...
density =21.0/2.00=10.5 g/ cm^3
For this problem, the solution is exhibiting some colligative properties since the solute in the solution interferes with some of the properties of the solvent. We use equation for the boiling point elevation for this problem. We do as follows:
<span>
ΔT(boiling point) = (Kb)mi
</span>ΔT(boiling point) = (0.512)(1.3/2.0)(2)
ΔT(boiling point) = 0.67 degrees Celsius
<span>
T(boiling point) = 100 + 0.67 = 100.67 degrees Celsius</span>
The atomic number is the same as the number of protons, so the answer is 25.
