Answer:
Option c. Neutral
Explanation:
Only neutral solution gives a green colouration to a pH paper
6CO₂(g) + 6H₂O(l) → C₆H₁₂O₆(s) + O₂(g)
<u>Explanation:</u>
In our real life we can have the example of chemical reaction that is photosynthesis. In the photosynthesis of plants, plants making their food by means of using water in the liquid state, carbon-di-oxide in the gaseous state obtained from the sun to produce glucose and water, in which glucose is in the solid state and oxygen is in the gaseous state. The balanced equation can be given as,
6 CO₂(g) + 6 H₂O(l) → C₆H₁₂O₆(s) + O₂(g)
Answer:
2.48 mol/L.
Explanation:
- The molarity of the solution can be expressed as <em>the number of moles of solute in 1.0 liter of the solution, </em>(M = n / V).
- It is also can be calculated from the relation:
<em>M = (mass / molar mass) solute x (1000 / V of solution)</em>
The solute is toluene and the solvent is benzene.
mass of toluene (solute) = 57.1 g,
molar mass of toluene (solute) = 92.14 g/mol.
volume of the solution = 250 ml.
∴ M = (mass / molar mass) solute x (1000 / V of solution) = [(57.1 g / 92.14 g/mol) x (1000 / 250 ml)] = 2.48 mol/L.
