A piston has an initial volume of 1.643 L at a pressure of 128 kPa. The temperature is maintained at 27 oC as the volume is decr

aivan3 [116]

Answer:

<u>355 kPa</u>

Explanation:

The ideal gases follow Boyle's law: at constant temperature pressure and volume are inversely related:

$PV=constant$

$P_1V_1=P_2V_2$

$P_2=\dfrac{P_1V_1}{V_2}$

Subsituting and computing:

$P_2=\dfrac{1.643L\times 128kPa}{0.593L}\approx355kPa$

bogdanovich [222]

Answer:

Lower heat capacity

Explanation:

The heat or thermal capacity is a physical property defined as the amount of heat a material need in order to elevate a unit in its temperature, this means that water increases its temperature more easily than land.

BlackZzzverrR [31]

There are no options so I'll just give my answer. Intermolecular hydrogen bonding is responsible for the high boiling point of water. The presence of hydrogen bonds can cause an anomaly in the normal succession of states of matter for certain mixtures of chemical compounds as temperature increases or decreases.

Be sure to answer all parts. Compounds a and b are isomers having molecular formula c5h12. Heating a with cl2 gives a single pro

Elden [556K]

Neo-pentane represents the Compound A while compound B is n-pentane.

After careful consideration we can say that compounds A and B are alkanes and also isomers of pentane. In chemistry, Isomers are defined as compounds having same empirical molecular formula but different structural formulas due to varying arrangement of atoms.

Now, as per the question statement, compound A gives a single monochlorination product upon heating with the molecule of chlorine i.e. Cl2 showing that the molecule is extremely symmetric. This molecule must be neo-pentane. Refer to image 1.

Similarly, Compound B forms 3 constitutional isomers after undergoing monochlorination. This compound must be n-pentane since three are 3 different types of carbon atoms in the structure. Refer to image 2.
