cluponka [151]3 years ago

5 0

Answer:

Explanation:

The atomic sublevel with the next highest energy after the 4p is 5s.

Based on Aufbau's principle; the sublevels with lower energies are filled up before those with higher energies.

Sublevels do not fill up based on numerical order. The pattern of filling is shown as:

1s 2s 2p 3s 3p 4s 3d 4p 5s 4d 5p 6s 4f 5d 6p

How many grams of oxygen are required to react with 12.0 grams of octane(C8H18) in the combustion of octane in gasoline?

solniwko [45]

Answer : 42 grams of oxygen are required.

Explanation :

Step 1 : Write balanced chemical equation.

The combustion reaction of octane with oxygen can be written as,

$2 C_{8}H{18} (g) + 25 O_{2} (g) \rightarrow 16 CO_{2} (g) +18 H_{2}O (g)$

Step 2 : Find moles of octane.

The given mass of octane is 12 g

Molar mass of octane is 114.2 g/mol

The moles of octane are calculated as,

$moles =\frac{grams}{MolarMass} =\frac{12g}{114.2g/mol} = 0.105 mol$

We have 0.105 mol octane.

Step 3: Use mole ratio from balanced equation to find moles of O₂

The mole ratio of octane and O₂ is 2 : 25. Let us use this as a conversion factor.

$0.105 mol C_{8}H_{18} \times\frac{25mol O_{2}}{2molC_{8}H_{18}} = 1.31 mol$

We have 1.31 mol O₂.

Step 4 : Convert moles of O₂ to grams.

The molar mass of O₂ is 32 g/mol.

The grams of O₂ can be calculated as,

$1.31 mol O_{2} \times\frac{32g}{mol} = 42 grams$

42 grams of oxygen are required.

How many H atoms are in 6.43g x 10^24 molecules of water

kow [346]

Answer:

$12.86\times 10^{24}$ atoms of hydrogen

Explanation:

The molecular formula for a water molecule is $H_2O$ .

From the above formula, we can conclude that 1 molecule of water contains 2 atoms of hydrogen and 1 atom of oxygen.

There are $6.43\times 10^{24}$ molecules of water.

1 molecule of water = 2 atoms of hydrogen.

∴ $6.43\times 10^{24}$ molecules of water = $2\times 6.43\times 10^{24}=12.86\times 10^{24}$ atoms of hydrogen.

Therefore, there are $12.86\times 10^{24}$ atoms of hydrogen in $6.43\times 10^{24}$ molecules of water.

What is the third most common gas found in the air we breathe?

erastovalidia [21]

Argon is the third most common gas found in the air we breathe. The air we breathe has approximately 78% nitrogen and 21 % oxygen. The third more abundant gas in the air we breathe is Argon. It is available in a very small quantity in the air that we breathe. The percentage of the gas argon is about 0.9% in the air that we breathe. There are several other gases also present in the air that we breathe, but they are found mostly in negligible amounts.
