How many neutrons does element X have if its atomic number is 41 and its mass number is 162?

Answers

Answer 1

Answer: Isn't this Chemistry.... But anyways am a budding Biochemist

(Mass #) = (Atomic #) + (Neutron #)
: . (Neutron #) = (Mass #) - (Atomic #)
= 162 - 41
= 121

Note that: Atomic # = Amount of Protons = Amount of Electrons

Which reaction occurs most rapidly at standard conditions?H2(g) + I2(s) 2HI(g)
Cu(s) + S(s) CuS(s)
C6H12O6(s) + 6O2(g) 6CO2(g) + 6H2O(g)
5C2O42-(aq) + 2MnO4-(aq) + 16H+(aq) 10CO2(g) + 2Mn2+(aq) + 2H2O(l)
Ag+(aq) + I-(aq) AgI2(s)

Answers

I don't know of any way to determine the relative rates of reactions other than pretty much just guessing. Even with guessing, I can't decide between the last two. Both occur in solution and (if I recall correctly) both occur quite rapidly. I would guess that the last one, just a simple precipitation, would probably be the fastest.

(NOTE: You have the wrong equation on the last one. It should be Ag+(aq) + I-(aq) --> AgI(s) There is no subscript on the iodide ion in AgI.)

Which BEST describes the orbit of the Moon around Earth?Select one:
a. circular with a period of about one month
b. circular with a period of about one week
c. elliptical with a period of about one month
d. elliptical with a period of about one week

Answers

The statement that best describes the moon's orbit around the Earth is c. elliptical with a period of about one month. Although its orbit is elliptical, the moon's orbit can be described as nearly circular because it has an eccentricity of 0.05. Moreover, it takes around 27.322 days for it to orbit around the Earth once.

Explain how cellular respiration is the opposite reaction to photosynthesis.

Answers

Answer:

this is because during photosynthesis oxygen is released and in cellular respiration oxygen is taken in or inhalation takes place

hope it helps

Answer:

Cellular Respiration and Photosynthesis are almost opposite processes because photosynthesis removes carbon dioxide from the atmosphere while cellular respiration puts back carbon dioxide. Cellular respiration uses oxygen and has it's waste product of carbon dioxide (CO2).
