explain why a s bond formed by overlap of an s orbital with an sp3 orbital of carbon is stronger than a sbond formed by overlap

sp^{3} orbital have less electron density than p orbital. Therefore on overlap of s orbital with sp^{3} less repulsion take place than overlapping of sp3 orbital.

Electronegativity depends on s character.

In sp^{3}  there is hybridization between one s and 3 p orbital. Therefore,   sp^{3}have 25% of s character .

In p orbital , there is no s orbital present. Therefore s character is p orbital is 0% .

Higher the electronegativity means higher tendency to attract electron.

Thus, bond form by overlap of sp^{3} and s will be stronger than bond formed by overlap of s with p.

250 mL of a solution of calcium oxalate is the evaporated until only a residue of solid calcium
Lana71 [14]

Answer:

2.3 * 10^-5

Explanation:

Recall that the solubility of a solute is the amount of solute that dissolves in 1 dm^3 or 1000cm^3 of solution.

Hence;

Amount of calcium oxalate = 154 * 10^-3/128.097 g/mol = 1.2 * 10^-3 mols

From the question;

1.2 * 10^-3 mols dissolves in 250 mL

x moles dissolves in 1000mL

x = 1.2 * 10^-3 mols * 1000/250

x= 4.8 * 10^-3 moldm^-3

CaC2O4(s) ------->Ca^2+(aq) + C2O4^2-(aq)

Hence Ksp = [Ca^2+] [C2O4^2-]

Where;

[Ca^2+] = [C2O4^2-] = 4.8 * 10^-3 moldm^-3

Ksp = (4.8 * 10^-3)^2

Ksp = 2.3 * 10^-5

The element lanthanum has two stable isotopes, lanthanum-138 with an atomic mass of 137.9 AMU and lanthanum-139 with an atomic m
dmitriy555 [2]

Answer:

A. there is an isotope of lanthanum with an atomic mass of 138.9

Explanation:

By knowing the different atomic masses of both Lanthanum atoms, we can not tell anything about their occurence in nature. Therefore, all the last three options are incorrect. Because, the atomic mass does not tell anything about the availability or natural abundance of an element.

Now, the isotopes of an element are those elements, which have same number of electrons and protons as the original element, but different number of neutrons. Therefore, they have same atomic number but, different atomic weight or atomic masses.

Hence, by looking at an elements having same atomic number, but different atomic masses, we can identify them as isotopes.

Thus, the correct option is:

<u>A. there is an isotope of lanthanum with an atomic mass of 138.9.</u>

A certain chemical reaction releases 27.4 kJ/g of heat for each gram of reactant consumed. How can you calculate what mass of re
Fed [463]

A chemical reaction of exothermic kind releases energy in the form of heat and light.

We are given that reactant releases 27.4kJ/g for every gram of reactant consumed.

We are required to find number of grams of reactant that has been consumed

It is also given that 880J of energy is released

Hence, grams of reactants consumed is 880/27.4gm
