Answer:
Kinetic and potential energies are found in all objects. If an object is moving, it is said to have kinetic energy (KE). Potential energy (PE) is energy that is "stored" because of the position and/or arrangement of the object. The classic example of potential energy is to pick up a brick.
Explanation:
Kinetic energy is the energy of mass (an object) in motion (moving). The faster an object is moving, the more kinetic energy it has. Any object that is moving has kinetic energy – the moving object has energy because of its motion.
Answer:
A
Explanation:
I would say A because the sun makes energy right so if you are looking for an arrow or arrows I would say A I hope this helps!! and have a great day or night
Answer: C (Sugar's tendency to dissolve in water)
Answer:
This isotope has 59 electrons giving it a charge of -2.
Explanation:
To find this we have to understand isotope relates to the mass of the nucleus. This isotope has 59 electrons to counter the protons and give it a negative charge.
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
