You know oxygen is the limiting reactant (since it says there is excess hydrogen). So, use stoichiometry based on the given number of oxygen moles:
Answer:
430 kPa
Explanation:
Use the formula PV/T = PV/T where the left side of the equation refers to the initial values and the right side refers to the final values: (170.2 kPa)(3.5 L)/(298 K) = (P)(1.35 L)/(293 K). The P represents the unknown pressure. Solving this equation gives us a value for P of 433.855 kPa, but because of significant figures (the two from 3.5 L), we round to 430 kPa.
<span>When the unknown liquid is heated and turned into vapor, it will not occupy the entire container. The volume in the molar mass (nRT)/PV will be greater than the actually volume of the unknown, and the calculated molar mass will be less than the actual molar mass.</span>
Heat pumps most do work on a refrigerant in order to reverse the normal flow of thermal energy.
<u>Methylcyclohexane:</u>
The chemical formula of the organic compound, methylcyclohexane is
. It is branched into the group of saturated hydrocarbon.
Note: Refer the attached image for the structure of methylcyclohexane
<u>Structure of methylcyclohexane:</u>
- It is a monosubstituted cyclohexane because it has one branching through the attachment of single methyl group on one carbon of the cyclohexane ring.
- Being very toxic to the aquatic ecosystem, the methyl group of this compond in its axial position experiences a steric strain or steric crowding.
