Answer:
94448421.2201
Explanation:
multiply the value in kilometers by the conversion factor '0.62137119223684'.
So, 152000 kilometers = 152000 × 0.62137119223684 = 94448.42122 miles.
Answer:
Electrons on atoms have different amounts of energy proportional to the distance of their orbital from the nucleus. So in the flame, electrons get excited and pushed to higher energy levels by the heat energy. When they fall back down, they give off photons of light of different colors, based upon how far they fall.
Answer:
800mL
Explanation:
Using Boyle's law which states that the volume of a given mass of gas is inversely proportional to the pressure, provided temperature remains constant
P1V1= P2V2
P1 = 2 atm, V1 = 2000mL ,
P2 = 5atm , V2 = ?
2 × 2000 = 5 × V2
Divide both sides by 5
V2 = 4000 ÷ 5
V2 = 800mL

Answer:
It has 5 neutrons
Explanation:
The fact that it is a neutral atom tells us that the number of electrons and protons is the same:
- The problem tells us there are 4 electrons, thus there are 4 protons.
The average mass of an atom is the sum of the number of protons and the number of neutrons:
- Mass = # Protons + # Neutrons
With the above information in mind we can <u>calculate the number of neutrons</u>:
- 9 amu = 4 Protons + # Neutrons
