Students were inquired to answer a question at schools and to assert what is most important for them to succeed. Of the many answers, one that that stood out was practice. Persons who commonly are successful do not become successful by being born. They work hard and perseverance their lives to succeeding. If you wish to attain your goals, keep this in mind! shown below are one of the answer and question example that you could actually utilise to practice and develop your information and also give you insights that would guide you to sustain your study in school.
Which compound is least soluble in water at 60.°C?
(1) KClO3 (3) NaCl
(2) KNO3 (4) NH4Cl
KClO3 is the least soluble compound in water at a temperature of 60 degree centigrade. The correct option in regards to the given question is option “1”. For determining the solubility of a substance at 60 degree centigrade it is important to know the table that shows the solubility of different substances at 60 degree centigrade.The solubility of the substances provided in the question can be noted down as
KClO3 = 23.8
KNO3 = 103.4
NaCl = 37.04
NH4Cl = 55.3
Seeing the above records we can easily say that the solubility of KClO3 is the lowest at 60 degree centigrade.
From the answer and question examples above, hopefully, they can definitely assist the student sort out the question they had been looking for and take note of all sorts of things declared in the answer above. Then will be able to carry out some sharing in a group discussion and also learning with the classmate regarding the topic, so another student also attain some enlightenment and still keeps up the school learning.
