when 20.87 g of propane is combusted in excess oxygen, how many grams of co2 are produced and how many grams of o2 are consumed?

Answers

When 20.87 g of propane is combusted in excess oxygen 62.577g of co2 are produced and 75.89grams of o2 are consumed

What are combustion reactions?

combustion is a chemical reaction between two or more chemicals, usually involving oxygen, that produces heat and light in the form of a flame. When a material reacts quickly with oxygen, a combustion reaction happens (O2).

During the combustion of propane the following reaction occurs:

C3H8(g)+5O2(g)→3CO2(g)+4H2O(l)

We know that the combustion of 1 mole of propane gives 3 moles of carbon dioxide.

= 20.87 g/44.10⋅g⋅mol−1=0.473⋅mol

And since, per the stoichiometric equation, if 0.200⋅mol propane is completely combusted, 3×0.473mol×44.10⋅g⋅mol−1=62.5779g

Oxygen consumed can be considered as x

44x=20.87x160=75.89g

Therefore when 20.87 g of propane is combusted in excess oxygen 62.577g of co2 are produced and 75.89grams of o2 are consumed.

What is the pOH when 10 mL of 0.2 M CH3NH2 (pKb = 3.36) is titrated with 10 mL of 0.1 M HCl?

Answers

The solution of the base would have a pOH of  3.66 when titrated.

What is the pOH of the base?

We know that pOH can be obtained from the concentration of the base and we can be able to work out the pOH when we attempt to apply the Henderson–Hasselbalch equation to a basic solution.

Number of moles of the salt = 10/1000 * 0.2 M

= 0.002 moles

Number of moles of the acid = 10/1000 L * 0.1 M

= 0.001 moles

Total volume = 10 mL + 10 mL = 20 mL or 0.02 L

Molarity of the salt =  0.002 moles/0.02 L

= 0.1 M

Molarity of the acid =  0.001 moles/0.02 L

= 0.05 M

Then;

pOH = pKb + log (salt/base)

pOH = 3.36 + log( 0.1 M/0.05 M)

pOH = 3.66

What does bonding mean in chemistry and its types?

When two or more atoms, molecules, and ions join together chemically to form a compound, this process is known as chemical bonding. These chemical bonds hold the atoms in the resulting molecule together.

The four main types of bonding—ionic, covalent, metallic, and molecular—are discussed in this section. Ice is a different kind of solid that plays a significant role in a few crystals.

How bonding is formed and its purpose?

To form bonds, atoms exchange or trade their valence electrons. The electrons in an atom's outermost energy level known as valence electrons have the potential to interact chemically. All chemical bonds are built on valence electrons.

The simplest explanation is that atoms are attempting to achieve the most stable (lowest-energy) state possible. Many atoms become stable when they satisfy the octet rule or have their valence shell completely filled with electrons.
