Answer:
1.67g H2CO3 are produced
Explanation:
Based on the reaction:
2NaHCO3 → Na2CO3 + H2CO3
<em>2 moles of NaHCO3 produce 1 mole of Na2CO3 and 1 mole of H2CO3</em>
To solve this question we need to find the moles of Na2CO3 = Moles of H2CO3. With their moles we can find the mass of H2CO3 as follows:
<em>Moles Na2CO3 -Molar mass: 105.99g/mol-</em>
2.86g Na2CO3 * (1mol/105.99g) = 0.02698 moles Na2CO3 = Moles H2CO3
<em>Mass H2CO3 -Molar mass: 62.03g/mol-</em>
0.02698 moles * (62.03g/mol) =
<h3>1.67g H2CO3 are produced</h3>
Answer:
C
Explanation:
It can already be seperated because the mixture hasn't disolved into the water yet.
Explanation:
When an atom bonds with another atom then it results in the formation of a chemical bond.
This formation of bond could be due to transfer or sharing of electrons.
When a chemical bond is formed due to transfer of electrons then this type of bond is known as ionic bond.
When a chemical bond is formed due to sharing of electrons then this type of bond is known as covalent bond.
