4 0

Answer:

12 orbitals

Explanation:

The suborbital = d orbital.

n = 4

The orbital is 4d.

There are 5 degenerate orbitals of d orbitals. Thus m value, -2, -1, 0, +1, +2 .

Thus, number of orbitals = 5

The suborbital = f orbital.

n = 4

The orbital is 4f.

There are 7 degenerate orbitals of f orbitals. Thus m value, -3, -2, -1, 0, +1, +2, +3

Thus, number of orbitals = 7

Total number of orbitals = 7 + 5 = 12

Describe all the relationships between pressure, volume, and temperature

hammer [34]

The pressure of a given amount of gas is directly proportional to its absolute temperature, provided that the volume does not change (Amontons's law).

 The volume of a given amount of gas is inversely proportional to its pressure when temperature is held constant (Boyle's law).

What is the molecular formula of a compound with the empirical formula

ipn [44]

Answer: $C_2H_2O_2$

Explanation:

Molecular formula is the chemical formula which depicts the actual number of atoms of each element present in the compound.

Empirical formula is the simplest chemical formula which depicts the whole number of atoms of each element present in the compound.

The empirical formula is $CHO$

The empirical weight of $CHO$ = 1(12)+1(1)+1(16)= 29 g.

The molecular weight = 60 g/mole

Now we have to calculate the molecular formula:

$n=\frac{\text{Molecular weight}}{\text{Equivalent weight}}=\frac{60}{29}=2$

The molecular formula will be= $2\times CHO=C_2H_2O_2$

Thus molecular formula will be $C_2H_2O_2$

The system described by the reaction CO(g)+Cl2(g)⇌COCl2(g) is at equilibrium at a given temperature when PCO= 0.26 atm , PCl2= 0

givi [52]

Answer: The new pressure of CO is 0.09 atm

Explanation:

For the given chemical reaction:

$CO(g)+Cl_2(g)\rightleftharpoons COCl_2(g)$

The expression of $K_p$ for above equation follows:

$K_p=\frac{p_{COCl_2}}{p_{CO}\times p_{Cl_2}}$ .......(1)

We are given:

$p_{COCl_2}=0.66atm\\p_{CO}=0.26atm\\p_{Cl_2}=0.15atm$

Putting values in above equation, we get:

$K_p=\frac{0.66}{0.15\times 0.26}\\\\K_p=16.92$

Addition pressure of chlorine added = 0.39 atm

Now, the equilibrium is re-established:

$CO(g)+Cl_2(g)\rightleftharpoons COCl_2(g)$

Initial: 0.26 0.15 0.66

At eqllm: 0.26-x 0.54 0.66+x

Putting values in expression 1, we get:

$16.92=\frac{(0.66+x)}{(0.26-x)\times 0.54}\\\\x=0.17$

So, new pressure of CO = 0.26 - x = (0.26 - 0.17) = 0.09 atm

Hence, the new pressure of CO is 0.09 atm
