Answer:
The answer is 2, 12 g of LiCl in 1 L of solution
Explanation:
We calculate the weight of 1 mol of LiCl:
Weight 1 mol LiCl= Weight Li + Weight Cl =6, 94 g + 35, 45 g= 42,39 g/mol
In a 0.05M solution it means that we have 0.05 moles of compound (in this case, LiCl) in 1 liter of solution:
1 mol---------42, 39 g LiCl
0,05mol-----x=(0,05molx 42, 39 g LiCl)/ 1 mol =2, 1195 g LiCl
The correct answer as to which observation most likely indicates that only a chemical change has taken place would that the change cannot be reversed.
When it comes to changes in a system, it can either be:
- physical change
- chemical change
When a substance undergoes a physical change, the original version of the substance can be recovered. In other words, physical changes can be reversible.
When a substance undergoes a chemical change, the original version cannot be recovered because an entirely new product would have been formed. In other words, chemical changes are irreversible.
Thus, once a change becomes irreversible, such a change is said to be a chemical change.
