Answer:

there are three equivalent bonding MOs of equal energy and one unique bonding MO.

Explanation:

Let us recall that according to the principles of the molecular orbital theory, when a compound is formed, the number of bonding molecular orbitals must be equal to the number of antibonding molecular orbitals.

Now methane is formed from one carbon atom and four hydrogen atoms. There are four bonding molecular orbitals and four antibonding molecular orbitals.

Three out of the four bonding molecular orbitals are degenerate while one is unique.

in the laboratory a student dilute 13.3 ml of a 10.8 m hcl solution to a total of 300.0 ml what is the concentration of the dilu
krek1111 [17]

<u>Answer:</u> The concentration of the diluted solution is 0.4788M

<u>Explanation:</u>

To calculate the concentration of the diluted solution, we use the following equation:

M_1V_1=M_2V_2

where,

M_1\text{ and }V_1 are the molarity and volume of HCl solution

M_2\text{ and }V_2 are the molarity and volume of the diluted HCl solution.

We are given:

M_1=10.8M\\V_1=13.3mL\\M_2=?M\\V_2=300mL

Putting values in above equation, we get:

10.8\times 13.3=M_2\times 300\\\\M_1=0.4788M

Hence, the concentration of the diluted solution is 0.4788M

What is the coefficient for H2O when the equation ? Ca(OH)2(aq) + ? H3PO4(aq) → ? Ca3(PO4)2(s) + ? H2O(ℓ) is balanced using the
kari74 [83]

Answer:

Coefficient of H_{2}O in the balanced equation with smallest possible integer is 6.

Explanation:

Unbalanced equation: Ca(OH)_{2}(aq.)+H_{3}PO_{4}(aq.)\rightarrow Ca_{3}(PO_{4})_{2}(s)+H_{2}O(l)

Balance Ca: 3Ca(OH)_{2}(aq.)+H_{3}PO_{4}(aq.)\rightarrow Ca_{3}(PO_{4})_{2}(s)+H_{2}O(l)

Balance PO_{4}  : 3Ca(OH)_{2}(aq.)+2H_{3}PO_{4}(aq.)\rightarrow Ca_{3}(PO_{4})_{2}(s)+H_{2}O(l)

Balance H and O: 3Ca(OH)_{2}(aq.)+2H_{3}PO_{4}(aq.)\rightarrow Ca_{3}(PO_{4})_{2}(s)+6H_{2}O(l)

Balanced equation: 3Ca(OH)_{2}(aq.)+2H_{3}PO_{4}(aq.)\rightarrow Ca_{3}(PO_{4})_{2}(s)+6H_{2}O(l)

So coefficient of H_{2}O in the balanced equation with smallest possible integer is 6.
