Solution is said to be saturated, if it contains maximum amount of solute that it can hold. On other hand, if solution contains less amount of solute as compared to its maximum capacity, it is referred as unsaturated solution.
It may be noted that, solubility of system is depends on temperature.
Now, if solution is unsaturated then it will dissolve more solute, when added in it. Thus, <span>sodium nitrate when added to solution get dissolves, it suggest that solution is unsaturated. </span>
Answer:
We need 6.0 moles of aluminium
Explanation:
Step 1: Data given
Number of moles of H2 = 9.0 moles
Step 2: The balanced equation
2 Al + 6 HCl → 2 AlCl3 + 3H2
Step 3: Calculate moles Al
For 2 moles Aluminium, we need 6 moles HCl to produce 2 moles AlCl3 and 3 moles H2
For 9.0 moles of H2 we need 2/3 * 9.0 = 6.0 moles of aluminium
We need 6.0 moles of aluminium
Huh what type of question is that?!
Answer:
If an object has a higher density than the fluid it is in (fluid can mean liquid or gas), it will sink. If it has a lower density, it will float. Density is determined by an object's mass and volume. If two objects take up the same volume, but have one has more mass, then it also has a higher density.
