Answer : The number placed in front of
should be, three (3).
Explanation :
Balanced chemical reaction : It is defined as the number of atoms of individual elements present on reactant side must be equal to the product side.
The given unbalanced chemical reaction is,

This chemical reaction is an unbalanced reaction because in this reaction, the number of atoms of chloride and sulfate ion are not balanced.
In order to balanced the chemical reaction, the coefficient 3 is put before the
, the coefficient 2 is put before the
and the coefficient 3 is put before the
.
Thus, the balanced chemical reaction will be,

Therefore, the number placed in front of
should be, three (3).
The statement which describes how NO2- reacts in this equilibrium:
<span>H2SO3(aq) + NO2-(aq) HSO3-(aq) + HNO2(aq
is the second option - </span><span>B. as a Brønsted-Lowry base by accepting a proton.
</span>This is because bases take proton H+ in order to become HNO2.
Answer:
1.445 x 10²³ atoms.
Explanation:
- It is known that 1.0 mole of any element contains Avogadro's no. (6.022 x 10²³) of atoms.
<u><em>Using cross multiplication:</em></u>
1 mol of Ag contains → 6.022 x 10²³ atoms.
∴ 0.24 mol of Ag contains → <em>??? atoms.</em>
∴ The no. of Ag atoms in 0.24 mol = (0.24 mol)(6.022 x 10²³ atoms)/(1 mol) = 1.445 x 10²³ atoms.
Tetrahedral is the answer
Hey there!
Great question=)
Yes, this statement is true! Propane burns in air and it produces carbon dioxide and water.
I hope this helps;)
