B. There were 1,570 kJ of energy in the snack.
C. During her run, she used 755 Calories of energy.
D. During her run, she used 189 Calories of energy.
E. The runner used fewer Calories while running than she consumed during her snack.
F. The runner used more Calories while running than she consumed during her snack.
Answers
Answer:
B. There were 1,570 kJ of energy in the snack.
C. During her run, she used 755 Calories of energy.
F. The runner used more Calories while running than she consumed during her snack.
Explanation:
According to this question, a runner eats a snack with 375 Calories of nutritional energy. After her snack, she burns 3,160 kJ while running.
Since 1 Calorie = 4.184 kJ, it means that the runner consumed 375 × 4.184 = 1570 kJ of energy. In other words, THERE WERE 1,570 kJ OF ENERGY IN THE SNACK.
Also, the runner burns 3,160 kJ while running meaning that she equivalently burnt 3160/4.184 = 755.258 calories. Approximately, 755 calories of energy were burnt by the runner while running.
In a nutshell, the runner consumed 375 calories of energy in her snack but used up 755 calories while running. This means that the runner used more Calories while running than she consumed during her snack.

Water has a higher boiling point than expected because what?
Answers
Answer:
Water has strong hydrogen bonds between molecules. These bonds require a lot of energy before they will break. This leads to water having a higher boiling point than if there were only weaker dipole-dipole forces. Water also has a high specific heat.
Explanation:
Hope this helped it is what I could find!
Answer: Water has a higher boiling point than expected because hydrogen and oxygen form single covalent bonds. Molecules of water is bound together by strong attractions which needs high energy to break resulting to a higher boiling point of water than most substances.

How could a synthetic material such as Acegram affect society?
Answers
Explanation:
Synthetic fiber or synthetic fibre (in British English; see spelling differences) are fibers made by humans through chemical synthesis, as opposed to natural fibers that are directly derived from living organisms. They are the result of extensive research by scientists to improve upon naturally occurring animal and plant fibers. In general, synthetic fibers are created by extruding fiber-forming materials through spinnerets, forming a fiber. These are called synthetic or artificial fibers. Synthetic fibers are created by a process known as polymerization, which involves combining monomers to make a long chain or polymer. The word polymer comes from a Greek prefix "poly" which means "many" and suffix "mer" which means "single units". (Note: each single unit of a polymer is called a monomer). There are two types of polymerization: linear polymerization and cross-linked polymerization.
Synthetic material are madeup of monomers and long chain of monomers are known as polymers. The process is known as polymerization and the synthetic material are turned as microplastic which takes a long period of time to decompose. By this way the synthetic materials are very harmful for the society.

How many moles of Gold (III) sulfide must decompose to produce 4.32 moles of gold
metal given the reaction Au2S3 --> 2Au + 35
Answers
Answer:
2.16 moles of Au₂S₃ are decomposed.
Explanation:
Given data:
Number of moles of gold (III) sulfide decomposed = ?
Number of moles of gold metal formed = 4.32 mol
Solution:
Chemical equation:
Au₂S₃ → 2Au + 3S
Now we will compare the moles of Au₂S₃ with gold metal.
Au : Au₂S₃
2 : 1
4.32 : 1/2×4.32 = 2.16
2.16 moles of Au₂S₃ are decomposed.

Cell phones are widely used by people all over the world as a medium of communication. When a person makes a call from a cell phone, the cell phone emits electromagnetic waves that are intercepted by a nearby cell phone tower. The cell phone tower then connects the call to the phone of the person being called.
Which of the following processes enables a cell phone to receive communications from a cell phone tower?
A.
Electromagnetic waves from the tower produce an electric current in the cell phone's internal circuit when intercepted by the phone's antenna.
B.
Electromagnetic waves from the tower are reflected by the cell phone, producing an electromagnetic field that is detected by the internal circuits of the phone.
C.
Electromagnetic waves diffract around the cell phone's antenna, which allows the waves to be detected by the internal circuits of the phone.
D.
Electromagnetic waves from the tower interfere with the radio waves emitted by the cell phone, producing electric currents in the internal circuits of the phone.
Answers
Answer:
A Electromagnetic waves from the tower produce an electric current in the cell phone's internal circuit when intercepted by the phone's antenna.
Explanation:
Its correct I just did it
The correct option is A which is when a cell phone's antenna picks up electromagnetic waves from a tower, the phone's internal circuit becomes electrically charged through which communication is enabled.
How does a cell phone receive communications from a cell phone tower?Radio waves are sent by mobile phones through a base station network, which is a collection of permanent antennas. Since radiofrequency waves are electromagnetic fields rather than ionising radiation like X-rays or gamma rays, they cannot ionise or destroy chemical bonds in living organisms.
A cell tower has several antennas linked to it, usually positioned on a head frame. Even more than 15 antennas per carrier are found on some towers. This figure largely depends on the performance, area of coverage, and capacity needs of the antenna.
Effect of 5G on health: There are growing worries that the higher intensity radiation from 5G could harm those living close to cell towers. According to theories, the harm done to human DNA by this rise in radiofrequency radiation will result in cancer, premature ageing, and disturbance of cell metabolism.
