Why are all atoms electrically neutral?

Chemistry
1 answer:
Anna11 [10]3 years ago
7 0

Answer: Atoms are neutral if they have the same number of charged protons and electrons, balancing positive and negative charges. ... This is because water itself has slight charges. Answer 7: Atoms are electrically neutral because they have equal numbers of protons (positively charged) and electrons (negatively charged).

A chemical reaction can theoretically produce 1375.5 grams of product , but in actuality 112.9 grams are product . Which is the
zalisa [80]

Answer:

8.20 % → Percent yield reaction

Explanation:

To find the percent yield of reaction we apply this:

(Produced yield / Theoretical yield) . 100 = %

Produced yield = 112.9 g

Theoretical yield = 1375.5 g

We replace → (112.9g / 1375.5 g) . 100

8.20 % → Percent yield reaction

Which of the two forces is greater the force on the firefly or the force on the bus explain your answer please I really need hel
maksim [4K]

Answer: The force on the firefly

The unfortunate firefly hitting the bus does not change the velocity of the bus very much. Technically there is a change, but it's so very small and miniscule that it barely registers. To any casual observer not paying very close attention, they don't notice anything at all. So effectively the force on the firefly is a lot greater since the firefly got the worst end of the deal.

So in short, we look at the velocity of each object and see which velocity changed the most. In this case, the firefly's velocity changed from whatever speed it was flying to 0 when it stops flying all together. That's why the force is greater on the bug.

Reil [10]

Answer:

a. What is the wavelength?

The wavelength is 5 meters.

b. What is the frequency?

The frequency is 0.05Hz

c. What is the wave velocity?

The wave velocity is 0.25 meters per second

Explanation:

the wavelength is the distance between two troughs or two crests, which in this case is 5 meters.

the frequency=cycles/time. For this equation the equation would be 1/20, which is 0.05

the wave velocity=wavelength x frequency. Plug in the numbers, 5 x 0.05, and you will get 0.25.
