Tcecarenko [31]
The strong base will be dissociated completely into the aqueous solution. The pOH of the solution can be determined by the concentration of the hydroxide ion. The strong bases have lower pOH value.

What volume of CH4(g), measured at 25oC and 745 Torr, must be burned in excess oxygen to release 1.00 x 106 kJ of heat to the su
anastassius [24]

Answer:

V=27992L=28.00m^3

Explanation:

Hello,

In this case, the combustion of methane is shown below:

CH_4+2O_2\rightarrow CO_2+2H_2O

And has a heat of combustion of −890.8 kJ/mol, for which the burnt moles are:

n_{CH_4}=\frac{-1.00x10^6kJ}{-890.8kJ/mol}= 1122.6molCH_4

Whereas is consider the total released heat to the surroundings (negative as it is exiting heat) and the aforementioned heat of combustion. Then, by using the ideal gas equation, we are able to compute the volume at 25 °C (298K) and 745 torr (0.98 atm) that must be measured:

PV=nRT\\\\V=\frac{nRT}{P}=\frac{1122.6mol*0.082\frac{atm*L}{mol*K}*298K}{0.98atm}\\\\V=27992L=28.00m^3

Best regards.

Use the pop-up menus to label the following statements as either True or False. Only the methyl ester of aspartame is sweet. Tru
pickupchik [31]

Answer:

  • Only the methyl ester of aspartame is sweet. True
  • Amide bonds can be hydrolyzed under only acidic conditions. False
  • The zwitterionic form of the amide bond is the most favored resonance form. True
  • The phosphoric acid in soda hydrolyses the aspartame ester making it sweet. False

Explanation:

  • Aspartame is obtained by combining phenylalanine and aspartic acid. Its main impurity is dicetopiperazine, which does not possess sweetening properties.
  • Amide bonds can be hydrolyzed both under basic and acidic conditions.
  • The zwitterionic form of the amide bond is the most favored resonance form. A zwitterion is an electrically neutral chemical compound, but it has formal positive and negative charges on different atoms, presenting high stability
  •  Phosphoric acid creates an acidic medium that improves the absorption of carbon dioxide, reducing the pressure generated by carbon dioxide and thus allowing bottleneck. Phosphoric acid has a bitter taste that is offset by the addition of sugar
