2NO + O2 → 2NO. 2
Nitric oxide react with oxygen to produce nitrogen dioxide.
Answer : A solution that has reached equilibrium and has undissolved solute remaining in the solution must be, saturated solution.
Explanation :
Unsaturated solution : It is defined as the solution in which more solute particles can be dissolved in the solvent.
Saturated solution : It is defined as the solution in which no more solute particles can be dissolved in the solvent.
As per question, when a solution reached to equilibrium and some amount of undissolved solute remaining in the solution that means no more solute can be dissolved in the solvent then that solution will be saturated solution.
Hence, the solution must be saturated solution.
Answer:
- <u><em>Sodium chloride</em></u>
Explanation:
The attached graph with a green and a red arrow facilitates the understanding of this explanation.
To read the <em>solubility </em>on the <em>graph</em>, you can start with the temperature, on the x-axis.
The red vertical arrow shows how, departing from the <em>40ºC temperature</em> on the x-axis, you intersect the<em> solutibility curve </em>of sodium chloride at a height (y-axis) corresponding to <em>60 g/100cm³ of water</em> (follow the green horizontal arrow).
Hence, <em>sodium chloride is the salt that can dissolve at a concentration of about 60g/100cm³ of water at 40ºC.</em>
Answer:
2 moles CO2
Explanation:
According to the stoichiometric ratio the mole ratio of CaCO3:CO2 is 1:1
Therefore the moles of CO2 = 2 * (1/1)
= 2 mol CO2
