Would you expect salts like NaCl, which have singly-charged ions, to have larger or smaller lattice energies compared to salts l

IRINA_888 [86]

Answer:

NaCl has a smaller lattice energy compared to CaO

Explanation:

We have remember that lattice energy increases as the size of the ions in the ionic solid decreases. According to Oxford dictionary; lattice energy is "a measure of the energy contained in the crystal lattice of a compound, equal to the energy that would be released if the component ions were brought together from infinity."

We know that the larger the magnitude of charge on a cation the smaller in size the cation is and the size of anions increase from left to right in the periodic table. Hence Ca^2+<Na^+ and O^2- < Cl^-. Therefore the lattice energy of CaO is greater than that of NaCl.

Predict whether carbon dioxide or water would have a higher boiling point. Explain your prediction in terms of the attractions b

yulyashka [42]

Answer:

since ionic bonds, bonds that are charged, have very high boiling points, then the water would have a higher boiling point because it has a slight charge whereas carbon dioxide is stable.

Describe how the height of the tides changes from Monday to Thursday.

adoni [48]

One of the results is that the moon is near the earth and the other one, the oceans tide. Even though the earth can hold any object within
ts proximity, the ocean is partly attracted due to its liquid property. At night, the ocean tends to be attracted to the moon by creating a bulge and assigning it as ‘high tide’. This is due to the strong gravitational pull of th moon to the earth.

I hope this helps!
This might be right..

A student sees an absorbance a=1.140 for his solution that has a concentration of c=1.50*10-4 m using 0.50 cm cuvette. what is t

777dan777 [17]

The molar extinction coefficient is 15,200 $M^{-1} cm^{-1}$ .

The formula to be used to calculate molar extinction coefficient is -

A = ξcl, where A represents absorption, ξ refers molar extinction coefficient, c refers to concentration and l represents length.

The given values are in required units, hence, there is no need to convert them. Directly keeping the values in formula to find the value of molar extinction coefficient.

Rewriting the formula as per molar extinction coefficient -

ξ = $\frac{A}{cl}$
