Answer:
0.007756M KHP; 0.0009695 moles NaOH reacts; 0.03488M NaOH.
Explanation:
Potassium hydrogen phthalate, KHP, is a salt used as standard to determine concentration of basic solutions as NaOH solutions.
To find molarity of the KHP solution we need to convert mass of KHP to moles and divide this in 125mL = 0.125L:
<em>Moles KHP -Molar mass: 204.22g/mol-:</em>
0.198g * (1mol / 204.22g) = 0.0009695 moles KHP
<em>Molarity:</em>
0.0009695 moles KHP / 0.125L = 0.007756M KHP
NaOH reacts with KHP as follows:
NaOH + KHP → Na⁺ + KP⁻ + H₂O
That means 1 mole of NaOH reacts per mole of KHP, that means moles of NaOH that reacts are = Moles of KHP added:
0.0009695 moles NaOH reacts
In 27.80mL = 0.02780L the NaOH was contained. Molarity is:
0.0009695 moles NaOH / 0.02780L =
0.03488M NaOH
Osazones<span> are a class of carbohydrate derivatives found in organic chemistry formed when sugars are reacted with excess of phenylhydrazine. The famous German chemist Emil Fischer developed and used the reaction to identify sugars whose stereochemistry differed by only one chiral carbon</span>
Kinetic energy is produced when the amount of work done on an object relative to its change in energy.
Explanation:
A strong connection is present between within work as well as energy. When work is performed on an object energy is added along with it . Energy can be defined as ability to do certain amount of work on the other hand work means to change in energy . Kinetic energy is produced when the object is in moving position and potential energy is produced when the object is at resting position.
Charles law states a proportional relationship between volume and temperature.
V1= 100mL=0.1L
V2=400mL=0.4L
T1=80'c+273=353K
T2=?
T2=1412K-273=1139'C
