Answer: You could put the frozen block of ice on the stove and let it melt and eventually boil out leaving the salt behind
Explanation:
Answer : The concentration of SO₂Cl₂ after 720 min will be, 
Explanation :
Expression for rate law for first order kinetics is given by:

where,
k = rate constant = 
t = time passed by the sample = 720 min
a = initial amount of the reactant = 
a - x = amount left after decay process = ?
Now put all the given values in above equation, we get


Therefore, the concentration of SO₂Cl₂ after 720 min will be, 
8.4 grams. I think but I’m not 100% sure
There a various tool that can be used to measure a specific volume of liquid, such as eyedroppers, cups, liter bottles, graduated cylinders, and beakers.
