<u>Answer:</u> The group of elements that corresponds to the electronic configuration
is group 13.
<u>Explanation:</u>
Electronic configuration is defined as the representation of electrons in a given atom.
Valence electrons are defined as the electrons present in the outermost shell or the sub-shell having highest value of 'n'.
We are given:
General electronic configuration =
where,
n = principal quantum number and is determines the energy level of the sub-shell
The number of valence electrons in the configuration are = 2 + 1 = 3
And, as the last electron is entering the p-subshell, so the element is a p-block element.
The given electronic configuration is of group 13 elements.
Hence, the group of elements that corresponds to the electronic configuration
is group 13.
Answer:
The ratio is 2:1, that is 2mol C / 1mol O2
Explanation:
First check to see if the equation is balanced. It is so now let's find the ratio.
The ratio is the stoichiomeric coefficient of the element or compound.
Carbon : Oxygen
2C : 1 O2 , so 2:1 ..
Answer:
pH = 3.0 ya that's it......
