Covalently bonded compounds differ from ionically bonded compounds because:

Chemistry
1 answer:
Damm [24]3 years ago
3 0

Answer:Covalently bonded materials are less dense than metallic or ionically bonded ones because covalent bonds are directional in nature whereas metallic and ionic are not; when bonds are directional, the atoms cannot pack together in a dense manner, yielding a lower mass density then solids with non-directional bonds.

Why might a geologist ask an analytical chemist to help identify the minerals in a rock.
Galina-37 [17]

 A geologist will ask an analytical chemist to help identify the minerals in a rock because an analytical chemist studies the composition of matter and, therefore, can identify the minerals.

The analytical chemist does this by determining the crystal structure as a matter of routine using X-ray and electron diffraction techniques.

If an element has two isotopes, what is the atomic mass if one of the isotopes has a mass of 15.000 amu and makes up 5.000% of t
olasank [31]
The atomic mass of element is the weighted average atomic mass of the element with respect to the abundance of the isotopes of that element 
atomic mass is the sum of the products of the mass of isotopes by their percentage abundance 
atomic mass = 15.000 amu x 5.000 % + 16.000 amu x 95.000 % 
                     = 0.7500 + 15.200
atomic mass of element is therefore 15.950

Which two elements have properties that are alike
Feliz [49]
Answer:
Barium and Calcium

Explanation:
When heated with chlorine,
Both calcium and barium are able to form ionic bonds.
Hydrogen can only form bonds that are partial positive. It is not strong enough to be considered an ionic bond.
Silicon forms strong covalent with chlorine, called silicon tetrachloride. The structure is in diamond form which requires a lot of heat energy to break the bonds are way more than energy needed to break the bonds between calcium chloride.
Krypton is an inert element which does not form bonds with any elements under standard conditions

The compound sodium carbonate is a strong electrolyte. Write the reaction when solid sodium carbonate is put into water:
Ludmilka [50]

The compound sodium carbonate is a strong electrolyte because it completely dissociates when placed in water into its component ions. The equation of the reaction can be expressed as:

Na_2CO_3_{(s)} ---> 2 Na^+_{(aq)} + CO_3^{(2+)}_{(aq)}

The dissociation leads to the formation of sodium and carbonate ions with the latter held together by its internal covalent bond.

This is unlike weak electrolytes that do not dissociate completely in water or aqueous solutions. Only a small fraction of the solute exists as ions in the solution.
