Answer:
Orbital Notation is more specific on where exactly the electron is placed.
Explanation:
When writing an electron configuration for an atom, rather than writing out the occupation of each and every orbital specifically, you instead lump all the core electrons together and designate it with a symbol of the corresponding noble gas on the Periodic Table.
the arrangement of electrons in the orbitals of an atom or molecule
While Orbital Notation is a visual transformation of the electron configuration. It shows you where each specific electron is placed and what its "spin" is.
Glad I could help!
Answer:
6.25% of the original amount
Explanation:
half-life means that half is gone for every certain period of time. Because the half life is 1 month, only half of the 'radionulide' is left every month.
after 1 month= 50%
after 2 months= 25%
after 3 months= 12.5%
after 4 months= 6.25%
Answer:
C: 1 mol F2/38 g F2
Explanation:
The reaction equation is;
N2 + 3F2 = 2NF3
Now, to know how many grams, of N2 is needed to completely react with 105 g F2 and since the molar mass of N2 is 28.02 g/mol, Molar mass of F2 is 38 g/mol, number of moles attached to N2 and F2 in the reaction are 1 and 3 moles respectively, then we will have;
105 g F2 × 1 mol F2/38 g F2 × 1 mol N2/3 mol F2 × 28.02 g N2/1 mol N2
Option C is Thus correct
Answer :
HCl : Bronsted-Lowry acid
: Lewis-acid
: Bronsted-Lowry base
: Lewis-base
Explanation :
According to the Bronsted Lowry conjugate acid-base theory, an acid is defined as a substance which donates protons and a base is defined as a substance which accepts protons.
According to the Lewis concept, an acid is defined as a substance that accepts electron pairs and base is defined as a substance which donates electron pairs.
HCl :
It is a Bronsted-Lowry acid that donates protons.
:
It is a Lewis-acid that accepts electron pairs.
:
It is a Bronsted-Lowry base that accepts protons.
:
It is a Lewis-base that donates electron pairs.
PV=nRT<=> P=nRT/V=2,40*R*(273+97)/45 atm.
Calculate it. R is a number that is given, find it and use your math to solve.
