Answer is B) - neutrons.


Both protons and neutrons contribute to the mass of an atom. But ₈¹⁷O atom has atomic number as 8. Hence, number of protons is 8. Atomic mass of the given atom is 17.


Atomic mass = number of protons + number of neutrons


Hence, number of neutrons in the given atom is 17 - 8 = 9.


So, the number of neutrons is greater than the number of protons. Hence the greatest composition of ₈¹⁷O atom is neutrons by mass.

Ivanshal [37]

Answer:

Mass is the same but it weights 64 Newtons

Explanation:

First of Mass is the same in any sort of gravity. Now let's calculate weight

W = MG

where W = Weight

M = Mass

G = Gravity

W = (40kg)(1.6)

W = 64

Sorry for the spelling mistakes, hope this helps

In the combined gas law, if the volume is decreased, what happens to the temperature if pressure remains constant?
Flura [38]

The correct answer is A. In the combined gas law, if the volume is decreased and the pressure is constant, then the temperature decreases.

 <span>P1V1/ T1 = P2V2 / T2</span>

 <span>Assume the volume decrease by half; V2 = V1/2</span>

 <span>P1V1/ T1 = P2V1 /2 T2</span>

 <span>Cancelling terms,</span>

 <span>1/T1 = 1/2 T2</span>

T2 = T1/2

 <span>Thus, the temperature decreased.</span>

3. How many atoms in 3.91 moles of sodium?
Gala2k [10]

Answer:

Explanation:

The formula for sodium is Na. It does not form a molecule in some way.

1 mol Na = 6.02*10^23 atoms

3.91 mol = x                                    Cross multiply

x = 3.91 * 6.02 * 10^23

x = 23.65 * 10^23

x = 2.365 * 10^24

Scientific notation is always expressed as a number 1 ≤ x < 10
