Thank you for posting your question here at brainly.
<span>Calories heat added = Mass of glass times temp. increase times specific heat of glass
</span>
<span>calories (small calories) = l.0 g x 20 degrees x .16 calories/gm/degree C = 3.2 calories</span>
The best and most correct answer among the choices provided by the question is the second choice "<span>the moon’s orbital period and distance from Earth"
</span> <span>The Earth's mass is </span>5.9736<span> x 10</span>24<span> kg. That's a big number, so let's write it out in full: 5,973,600,000,000,000,000,000,000 kg. You could also say the Earth's mass is </span>5.9<span>sextillion tonnes. Phew, that's a lot of mass.</span>
I hope my answer has come to your help. God bless and have a nice day ahead!
Answer:-
27.38%
Explanation:-
Molecular weight of sodium hydrogen carbonate NaHCO3
= 23 x 1 + 1 x 1 + 12 x 1 + 16 x 3
= 84 gram
Total sodium Na present in NaHCO3 = 23 x 1 = 23 gram
Percentage of sodium present=
Total sodium x 100/ (Total molecular weight)
= 23 x 100 / 84
= 27.38 %
stable arrangement
<h3 /><h3>What is electron configuration of ions?</h3>
Their valence shell contains two or eight electrons. They don't acquire, shed, or distribute electrons.
An atom with a full outermost (valence) shell has a stable electrical configuration. The quantity of electrons that leave or enter an atom's outer shell is known as its valency.
A noble gas configuration is a stable electron configuration for representative or main group elements. By acquiring or losing electrons and forming ions, or by sharing electrons with other atoms, the representative elements' atoms can adopt a noble gas structure.
The stability of an electron arrangement can be predicted. When all of an atom's orbitals are filled, it is at its most stable and unreactive. The combinations with full energy levels are the most stable.
