Answer: The balanced chemical equation for the combustion of benzene is:

$2C_6H_6+15O_2\rightarrow 12CO_2+6H_2O$

Explanation:

Combustion reactions : It is defined as the reactions in which a hydrocarbon reacts with oxygen gas to produce carbon dioxide and water as a product.

Balanced chemical reaction : It is defined as the reaction in which the number of atoms of individual elements present on reactant side must be equal to the product side.

The balanced chemical equation for the combustion of benzene will be:

$2C_6H_6+15O_2\rightarrow 12CO_2+6H_2O$

By Stoichiometry of the reaction we can say that,

2 mole of benzene reacts with 15 moles of oxygen gas to produce 12 moles of carbon dioxide and 6 moles of water molecule.

How many grams of lead(II) sulfate (303 g/mol) are needed to react with sodium chromate (162 g/mol) in order to produce 0.162 kg

Afina-wow [57]

Answer : The mass of $PbSO_4$ needed are, 1.515 grams.

Explanation :

First we have to calculate the mole of $PbCrO_4$ .

$\text{Moles of }PbCrO_4=\frac{\text{Mass of }PbCrO_4}{\text{Molar mass of }PbCrO_4}=\frac{0.162g}{323g/mole}=0.005mole$

Now we have to calculate the moles of $PbSO_4$ .

The balanced chemical reaction will be,

$PbSO_4+Na_2CrO_4\rightarrow PbCrO_4+Na_2SO_4[tex]From the balanced chemical reaction, we conclude thatAs, 1 mole of [tex]PbCrO_4$ produced from 1 mole of $PbSO_4$

So, 0.005 mole of $PbCrO_4$ produced from 0.005 mole of $PbSO_4$

Now we have to calculate the mass of $PbSO_4$

$\text{Mass of }PbSO_4=\text{Moles of }PbSO_4\times \text{Molar mass of }PbSO_4$

$\text{Mass of }PbSO_4=0.005mole\times 303g/mole=1.515g$

Therefore, the mass of $PbSO_4$ needed are, 1.515 grams.

Which electron in sulfur is most shielded from nuclear charge?

natima [27]

Answer: 3p Orbitals

Explanation:

Electrons present in the 3p orbitals are farthest from the nucleus. Therefore, the electrons present in the 3p orbital will be shielded by the electrons present in the inner orbitals. Hence, 3p orbital in sulfur is most shielded from the nuclear charge".

The molecule of ethane posses which hybridization..........

LiRa [457]

Answer:

Sp3

Explanation:

Hydrocarbon can be defined as an organic compound that comprises of hydrogen and carbon only. Some examples of hydrocarbon are methane, butane, ethane, ethene, etc.

Hybridization can be defined as a phenomenon which involves the combination of two or more atomic orbitals to form the same number of hybrid orbitals, with each of the orbitals having the same shape and energy.

In Organic chemistry, ethane is considered to be a tetrahedral carbon and it's Sp3 hybridized.

A tetrahedral carbon typically comprises of four bonds that are 109. 5° apart while a linear carbon atom comprises of two (2) bonds that are 180° apart.

Hence, the molecule of ethane posses a Sp3 hybridization because it has four bonds arrange with a tetrahedral geometry.
