What is the mass of an element with 15 protons, 13 electrons, and 11 neutrons? *
RSB [31]

Answer:

The mass of the element is 26.20 amu

Explanation:

In this question, we are asked to calculate the mass of an element with 15 protons, 13 electrons and 11 neutrons

To calculate the atomic mass of the element, we take into consideration the masses of the individual sub atomic particles

Electrons have 0 atomic mass unit(their masses are negligible) we have no business here, Protons have a mass of

1.00727647 amu, while the mass of neutron is 1.0086654 amu

The mass of 15 protons is thus 15 * 1.00727647 = 15.10914705 amu

The mass of 11 neutrons is 11 * 1.0086654 =

11.0953194 amu

Adding this together, we have ; 11.0953194 + 15.10914705 = approximately 26.20 amu

A gas mixture contains the following gases with the mole fractions indicated: nitrogen (0.21), oxygen (0.16), carbon dioxide (0.
alukav5142 [94]

Answer:

Mole fraction Ar = 0.31

Explanation:

Remember that the sum of the mole fractions in a mixture of gases = 1

Mole fraction = Moles from a gas / Total moles

Mole fraction N₂+ Mole fraction O₂+ Mole fraction SO₂+ Mole fraction CO₂ + Mole fraction Ar = 1

N₂ = 0.21

O₂= 0.16

CO₂ = 0.23

SO₂ = 0.09

Mole fraction Ar = 1 - 0.21 - 0.16 - 0.23 - 0.09

Mole fraction Ar = 0.31

We are given that when θ = 38.7°, the angle of refraction in the liquid is θ = 26.3°. Thus, from Snell's law, the index of refra
oee [108]

Answer:1.4

Explanation:

Angle of incidence= 38°

Angle of refraction=26.3°

From Snell's law: n= sin i/sinr

sin i= 0.6157

sin r= 0.4430

n= 0.6157/0.4430=1.4

Note, n is dimensionless

A drought hits the habitat of a semi-aquatic bird population. All ponds dry up, and fish populations decline. There are two grou
alexandr1967 [171]

Answer:

The population of the long-legged birds decreases.

Explanation:

The population of the short-legged birds increases whereas the population of  long-legged birds decreases due to availability of food in that environment. The long-legged birds feed on fish whose population decreases due to drought conditions so the population of long-legged birds also decreases while on the other hand, the population of short-legged birds increases or remain the same because they feed on the insects and the insects are available in large amount and less affected by the drought conditions.
