It's 10.
Mass = density x volume
M = 1g/ml(10ml) = 10g
C₆H₁₂O₆ + 6 O₂ ⇒ 6 CO₂ + 6 H₂O
This is an oxidation-reduction reaction, because oxidation numbers of carbon and oxygen atoms are different than before reaction.

Hey there!
B + O₂ → B₂O₃
Balance O.
2 on the left, 3 on the right. Add a coefficient of 3 in front of O₂ and a coefficient of 2 in front of B₂O₃.
B + 3O₂ → 2B₂O₃
Balance B.
1 on the left, 4 on the right. Add a coefficient of 4 in front of B.
4B + 3O₂ → 2B₂O₃
Our final balanced equation: 4B + 3O₂ → 2B₂O₃
Hope this helps!
Answer:
B
Keep the temperature at 20°C. Stir the solution
Explanation:
Solution:
The molecular equation is:
Now, the oxide ion reacts with water to produce hydroxide ions,
The ionic equation is:
The 
ions are present on both the sides, so the net ionic equation becomes,
Now, to determine acid and base, we will look at the definitions
Acid: It is defined as proton donor that is it donates 
ions.
Base: It is defined as proton acceptor that is it accepts ions.
In the ionic equation, water is donating ions to 
therefore it acts as an acid and oxide ion acts as a base.
