Answer:
0.13 M
Explanation:
The reaction equation is;
NaOH(aq) + KHC8H4O4(aq) ------> KNaC8H4O4(aq) + H2O(l)
Molar mass of KHP = 204.22 g/mol
Amount of KHP= mass/ molar mass = 0.3365 g/204.22 g/mol = 1.65 × 10^-3 moles
n= CV
Where;
C= concentration
V= volume in dm^3
n= number of moles
C= n/V = 1.65 × 10^-3 moles × 1000/250 = 6.6 × 10^-3 M
If 1 mole of KHP reacts with 1 mole of NaOH
1.65 × 10^-3 moles of KHP will react with 1.65 × 10^-3 moles of NaOH
From
n= CV
We have that only 12.44 ml of NaOH reacted
C= n/V = 1.65 × 10^-3 moles × 1000/12.44
C= 0.13 M
At the equivalence point, the KHP solution turned light pink.
Answer:
The natural method of removal of CO2 is
Photosynthesis by plants
Absorption of CO2 from the atmosphere by ocean water
Melting of glacial ice
Explanation:
Respiration of living organism : In this process, Oxygen is consumed(removed) and Carbon dioxide(CO2 ) is formed.So it forms CO2 .
Photosynthesis by plants: Green plant containing. prepare their food in presence of sunlight by using CO2 , water ,Hence CO2 is removed from atmosphere.
Evaporation of ocean water : It increases the level of CO2 in atmosphere. The heating of oceans surface Degassed CO2 to atmosphere.
Absorption of CO2 from the atmosphere by ocean water : the plants under the oceans needs CO2 to carry out photosynthesis .Hence oceans absorbs CO2 from atmosphere .Here, CO2 is removed from atmosphere.
Melting of glacial ice : Glacial ice absorb carbon dioxide because it does not have organism respiration (organisms releasing CO2 ).They capture large amount of CO2 and called CO2 sinks.(Remove CO2)
Answer:
To calculate the no. of moles you must know mass and molar mass of the product
Explanation:
no. of moles =mass/molar mass
Answer:
Percent yield = 57.7 %Explanation:
The properties of a compound are different than the properties of the element that forms it
