Just did it... got it wrong but it showed me the right answer, you welcome
Explanation:
Ionization energy is defined as the energy required to remove the most loosely bound electron from a neutral gaseous atom.
When we move across a period from left to right then there occurs a decrease in atomic size of the atoms. Therefore, ionization energy increases along a period.
But when we move from top to bottom in a group then there occurs an increase in size of the atoms. Hence, ionization energy decreases along a group.
(a) As Sb, Sn and I are all period 5 elements. Hence, these elements are arranged in order of increasing
as follows.
Sn < Sb < I
(b) As Sr, Ca, and Ba are all elements of group 2a. Hence, these elements are arranged in order of increasing
as follows.
Ba < Sr < Ca
Answer:
CH4 + 2 O2 - - - > CO2 + 2 H2O
Explanation:
hope this helps,
you can check by adding all the numbers on both sides
please mark it
Answer:
A
Chemical reaction rates vary with the conditions of the reaction, but nuclear decay rates are constant.
Explanation:
B/c chem reactions can be affected by temperature, pressure, etc. whereas, nuclear decays are constant. The decay rate itself is measured over a long period of time and it remains constant I believe.
Answer: The key difference between dissociation and solvation is that dissociation is the breakdown of a substance into the atoms or ions from which the substance is made of whereas solvation is the dissolution of a substance in a solvent due to the attraction forces between the solvent molecules.
