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

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)

In the field of material sciences, the term "substrate" is widely used to describe the base material on which various processing operations are carried out with predetermined reaction parameters to produce additional layers and films, such as coatings. As a result, there are numerous definitions available in the literature, depending on the substrate's applications and area of study. A substrate is a molecule that an enzyme interacts with. The enzyme's active site, where potential weak connections between molecules can form, is filled with a substrate.

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
