Assume you have 4 solids (A, B, C and D) of similar mass. Which of these requires the greatest energy input to melt?

Chemistry
1 answer:
bazaltina [42]3 years ago
7 0

The solid that require the greatest energy input to melt by mass is the option;

Covalent network

Solution Explanation

The elementary particles of a solid are held together by bonds that require an input of energy to unlock, and once broken, the particles are then able to change location within their containing vessels with less restrictions

Polar covalent molecular solids have the following characteristics;

a) Soluble in water b) Low melting point, b) Conduct electricity

Solids that are made up of a covalent network have the following characteristics

a) High melting point temperature b) Non conductive of electricity c) Not soluble in water

Solids of ionic compounds have the following characteristics;

a) High melting point temperature b) The liquid state and solution conducts electricity c) Soluble in water

Solids that have nonpolar covalent bonds have;

a) Low melting point b) Normally in the gaseous or liquid state b) Not water soluble

The covalent network, and the solids ionic compounds require the most energy to melt, however, the strength of the ionic bond in an ionic compound is a factor the charges present and the sizes of the atom, while the covalent network solid, are combined to <em>form essentially as a single molecule</em> and therefore require the greatest heat energy input to melt

When doing a titration what is the equivalency point of the neutralization reaction?
KengaRu [80]
The equivalency point is at the point of the titration where the amount of titrant added neutralize the solution. When it’s a strong acid strong base titration, the equivalence point will be 7. When it is a weak acid strong base, the equivalence point it more basic (the exact number depends on what acid and base you use). And when it is a strong acid weak base, the equivalence number is more acid (the exact number depends on what acid and base you use). Hope this helps!

16. Mass = 10g
inessss [21]

Actual volume=Final Volume-initial volume

\\ \sf\longmapsto 50ml-30ml=20ml

Now

\\ \sf\longmapsto Density=\dfrac{Mass}{Volume}

\\ \sf\longmapsto Density=\dfrac{10}{20}

\\ \sf\longmapsto Density=2g/ml
