Answer:
I am almost certain the answer is a marshmallow.
Hope that helps!
First we have to establish the chemical reaction. As a result of adding N<span>a2CO3 and AgNO3 products formed are NaNO3 and Ag2CO3. NaNO3 is a soluble substance when dissolved in water.
As a general rule, most Ag, Pb and Hg(I) compounds are considered insoluble. Ag2CO3 is insoluble in water hence the reaction given forms a precipitate. </span>
Answer:
= 64584.7176 g
or
= 64.5847 kg
Explanation:
From our question, we have been asked to find the mass of SO₂ containing 6.075 × 10^26 S atoms.
We know that from Avogadro's constant,
1 mole of a substance contains 6.02 x 10²³ ions/atoms/units
Thus,
1 mole => 6.02 x 10²³ atoms
x moles=> 6.075 × 10²⁶ atoms
We cross multiply;
x moles = (6.075 × 10²⁶ x 1)/(6.02 x 10²³)
= 1009.1362 moles
1 mole of SO2 = 64 g
1009.1362 moles = ?
=>
= 64584.7176 g
= 64.5847 kg

Mg2+...because it loses 2 electron which is on its valence shell making it empty and making it have jst 2 shells. The radius calculated from d nucleus to the new valence shell is then smaller than that of Cl^- and k+
