Give the net ionic equation for the reaction (if any) that occurs when aqueous solutions of sodium sulfide and iron(II) nitrate
Luda [366]

Answer:

Fe^2+(aq) + S^2-(aq) --------> FeS(s)

Explanation:

First let us look at the molecular equation;

Na2S(aq) + Fe(NO3)2(aq) --------> FeS (s) + 2NaNO3(aq)

Now, the net ionic equation usually shows the most important reaction that took place, in this case, the formation of the FeS precipitate.

Hence, ionically;

Fe^2+(aq) + S^2-(aq) --------> FeS(s)

Select all of the answers that apply.
nignag [31]

Answer:

e) intensity of precipitation f) location of precipitation.

Explanation:

Doppler radar can see not only the precipitation in a thunderstorm (through its ability to reflect microwave energy, or reflectivity), but motion of the precipitation along the radar beam. In other words, it can measure how fast rain or hail is moving toward or away from the radar. From a volume scan (a series of 360-degree sweeps, each tilting a little higher than the last), forecasters can get a detailed look at structures and movements in storms close to the radar. The farther away from the radar a storm is, the more coarse the view, because: 1) The radar beam spreads out with distance, like a flashlight beam, causing small features to be missed at a distance; and 2) The beam shoots straight as the earth curves away from beneath -- a horizon that forces the radar to miss more and more of the low and middle levels of a storm with distance.

The explanation was copy pasted from there^ so check it out.

Let's find the temperature when the pressure is equal to zero.
slega [8]

The significance of the point where the pressure drops to zero is that at that point the gases would completely show ideal behavior.

<h3>What is the gas law?</h3>

The gas laws can be used to describe the behavior of the ideal gases. It is pertinent to note that the ideal gas law can strictly be applied to gases that are at a high temperature and low pressure.

We can be able to find the  temperature when the pressure is equal to zero either be the use of the equation line or by experiment. In that case, we would be able to obtain the point at which the pressure drops to zero.

The significance of the point where the pressure drops to zero is that at that point the gases would completely show ideal behavior.

What is the mass of a<br> 12.31 cm3 piece of<br> copper having a density of<br> 8.96 g/cm3
max2010maxim [7]

Answer:

110.30 grams

You have to multiply by 8.96.

12.31 x 8.96 = 110.30 grams.

Therefore, that is your answer.

(Sorry I had to answer twice it was because of LukeG1).
