Compressibility refers to the amount or extent to which a substance can be compressed, also involving the the relationship between changes in volume due to applied pressure.
"They are harder than alkali metals" is a characteristic property of the alkaline earth metals.
<u>Option:</u> C
<u>Explanation:</u>
The strength of metallic bond is stronger in alkaline earth metals than alkali metals because of the existence of 2 electrons in its outermost or valence shell relative to alkali metal which has only 1 electron in valence shell. Thus alkaline earth metals are therefore harder than the alkali metals.
They are considered alkaline since they formulate solutions that have a pH higher than 7, rendering them alkaline or bases. Radium is produced by uranium decay, not all alkaline elements are radioactive. It's very toxic, and the handling is risky. Calcium and magnesium are essential for animals and plants.
Answer:
Carbon has the highest mass percent
Explanation:
Step 1: Data given
Predict the element that will have the highest mass percent composition in each compound without doing any calculations.
For C3H6O, carbon will have the highest mass percent. The molar mass of of Oxygen and carbon are more or less the same. But we have 3x more Carbon than oxygen.
Identify the element that has the highest mass percent composition in C3H6O .
atomic mass C = 12.01 g/mol
atomic mass O = 16.0 g/mol
atomic mass H = 1.01 g/mol
molar mass C3H6O = 58.08 g/mol
%C = (3*12.01 / 58.08) * 100 %
%C = 62.04%
%O = (15.99 /58.08) *100%
%O = 27.53 %
%H = (6*1.01 / 58.08) * 100%
%H = 10.43
Carbon has the highest mass percent
