The answer is C. sugar water. Sugar can dissolve in water completely and form the solution. While other three are all heterogeneous mixture.
We assume it as an ideal gas therefore we can use the
ideal gas equation to solve the problem. The ideal gas equation is expressed as
PV = nRT. We are given the volume, temperature and pressure. Therefore, we can solve for the amount of the gas in moles.
<span>
n = PV / RT
n = </span>1.00(3L) / (<span>0.08206 atm L/mol K ) 273 K
n = 0.1339 mol

Answer:
Reduction reaction
This is so because considering the reaction Cu 2+ has been reduced to Cu(s) by losing two electrons , and any other element that undergoes this stage is termed as a reduction reaction.
Hope this helps
