The ion n3− has _____ protons and _____ electrons.enter your answers as integers separated by a comma.
bearhunter [10]
The ion N³⁻ is called the azide ion. In its neutral state, it occurs as the element Nitrogen. The atomic number of Nitrogen is 7. When it turns into an anion (negatively charged ion), it gains 3 more electrons. That's why its net charge becomes -3. It means that the protons is still 7, but the electrons are now 10. 

Overall charge = +7 + -10 = -3

A sample of gas originally at 25 C and 1.00 atm pressure in a 2.5 L container is allowed to expand until the pressure is 0.85 at
aivan3 [116]

Answer:

Final volumeof the gas = 2.84 L

Explanation:

The formular to be used here is the general gas equation. the formular is being used because it gives the relationship between the three gas parameters (volume, temperature and pressure) mentioned.

The general gas equation is given as;

\frac{P1V1}{T1} = \frac{P2V2}{T2}

where;

P1 = initial pressure

V1 = initial volume

T1 = initial temperature

P2 = Final pressure

V2 = Final volume

T2 = Final temperature

From the question,

P1 = 1.00 atm

P2 = 0.85atm

T1 = 25C + 273 = 298K (Converting to kelvin)

T2 = 15C + 273 = 288K (Converting to kelvin)

V1 = 2.5L

V2 = ?

from the equation, making V2 subject of formula we have;

V2 = \frac{T2P1V1}{T1P2}

V2 = (1*2.5*288)/(298*0.85) = 2.84 L.

Tsunami waves are almost the same as ripples caused by throwing a rock into a pond. What is the major difference between the two
Daniel [21]

c. The energy source of tsunami waves is much greater

Explanation:

The major difference between a tsunami waves and ripple waves is that the energy source of tsunami waves is much greater compared to ripple waves.

Tsunami waves carry more energy compared to just a disturbance resulting from a ripple caused by dropping of a stone.

  • A tsunami is a large water wave caused by the displacement of water usually by an earthquake.
  • An earthquake is a releases elastic waves suddenly within the earth crust.
  • Water bodies at the epicenter are disturbed sending huge volume of energetic water loads to the land.
  • A ripple is just a product of a stone dropped inside the water.

Tsunamis are more energetic compared to ripples in water.
