Molecules huddle close together.
cannot form to any shape.
Answer:
then it will move 1 too 2
right maybe
Explanation:
3. Cl₂ + 2KI --> 2KCl + I₂
Cl = 2 Cl = 2
K = 2 K = 2
I = 2 I = 2
4. 2NaCl --> 2Na + Cl₂
Na = 2 Na = 2
Cl = 2 Cl = 2
5. 4Na + O₂ --> 2Na₂O
Na = 4 Na = 4
O = 2 O = 2
6. 2Na + 2HCl --> H₂ + 2NaCl
Na = 2 Na = 2
H = 2 H = 2
Cl = 2 Cl = 2
7. 2K + Cl₂ --> 2KCl
K = 2 K = 2
Cl = 2 Cl = 2
SOLUTION :
Law of conservation of Mass States that "Mass is neither created, nor destroyed".
→ Like Mass of Reactants = Mass of products.
REACTANTS :
- Mass of Sodium Carbonate(given) = 5.3g
- Mass of ethanoic acid(given)= 6g
The total mass of reactants:
= 5.3 + 6
= 11.3g
<h3>•Products are :</h3>
- Mass of Carbon Dioxide = 2.2g
- Mass of Sodium ethanoate = 8.2g
The total mass of products is :
= 2.2 + 0.9 + 8.2
= 3.1 + 8.2
= 11.3g
Hence the, Mass of Reactants = Mass of products
∴ The given reaction is in agreement with the law of conservation.
