Chemical properties can be determined by heat combustion, how they react with other chemicals, Oxidization (lose electrons, losing hydrogen, gaining oxygen), or toxicity.

V1/T1= V2/T2 V =volume T= temp (in kelvin unit)
2.5/(22+273)=V2/(43+273)
V2=2.7L
A gas produced in a chemical reaction can be collected by water displacement. Because the gas is collected over water, it is not pure but is mixed with vapor from the evaporation of the water. Dalton's law can be used to calculate the amount of the desired gas by subtracting the contribution of the water vapor.
I believe the correct answer from the choices listed above is option B. A double-replacement reaction happens when atoms in one compound switch places with atoms in another compound. <span> It is a type of chemical </span>reaction<span> where two compounds </span>react<span>, and the positive ions (cation) and the negative ions (anion) of the two reactants switch places. Hope this answers the question.</span>
