Thanks teacher but in question number 5 sometimes electron affinity can be referred as an the amount of energy absorbed when an extra electron is added to isolated gaseous ion

[@estifanosbesfat5879]

No 35 the answer is C b/c it must be used Kelvin scale with Charles law

[@bekboy2446]

Teacher question 29..i thin k its mistake . B/c .The species that would require the highest energy for the removal of one electron is d. F- (fluoride ion). Fluorine has a high electronegativity, meaning it strongly attracts electrons. Therefore, it would require the most energy to remove an electron from a fluoride ion.

[@essentialeducationtube]

No No the answer is correct .there is quite difference between flourine atom and flourine ions .flourine atom has high ionization energy or negativity but not flourine ions .you have to read more and more about ionic size my best the largest ionic size the smallest ionization energy

[@jemalabdule7045]

question number 3 I think it is wrong answer because periodic law states
the properties of elements is aperiodic function of their atomic mass. I think you assumed that by modern periodic law your answer suit for modern periodic law not for periodic law

[@essentialeducationtube]

No you have to read grade 9 chemistry text book page 40 and 41 both mendeelve and modern periodic table are periodic law. But mendeelve perodic law show some draw back .best of best answer is A. Thanks for your comment

[@FasikawAlie]

29 lay D because F- ha high electro negstivity

[@essentialeducationtube]

Please differentiate atom and ions

[@essentialeducationtube]

The answer given is correct

[@MahletTsegaye-um7sf]

Thanks teacher but I have 1 question on number 35, Don't we have to change the unit to kelvin since it is the SI unit?

[@essentialeducationtube]

You can use directly .but for ideal equation PV=nrt, you have to change the unit to k

Teacher question no 24 answer i think isn't correct .
Because decolorize of Br2 is used to check whether double or triple bond exists as our teacher teaches us .
Beterf thanks 🙏🏾✨️

[@essentialeducationtube]

No No ,you can check your grade 10 text book page 47 and do the activities given at this page and check other resources .teacher are not reference
