Na + NaNO3 = Na2O + N2
4 Na + 2 NaNO3 = 6 Na2O + N2
6 Na on each side
2 N on each side
6 O on each side
This kind of questions cannot be open because there might be many different answers depending of the focus.
In fact, I found the set of options that comes with this questions. This is:
A. behavior of ions.
B. molecular bonding.
C. molecular shape.
D. molecular motion.
Of course, the answer is the option D. molecular motion.
And, of course, you need an explanation.
It is good to know that the word kinetic refers to motion, so definetly kinetic molecular theory is a theory about the motion of the molecules.
With that you likely had been able to answer the question. But it is good to know what the molecular theory is.
The molecular kinetic molecular theory explains the properties and behavior of the gases in terms of the motion of its particles (molecules) making several assumptions about the energy, size and motion of such particles.
In order to calculate the amount of heat energy required to melt 347 grams of ice, we need to will apply the equation:
Q
= ml, where m is the mass of substance and l is its latent heat of
fusion. For ice, the latent heat of fusion is 334 joules per gram.
Therefore:
Q = 347 x 334
Q = 112,558 joules of energy
Hope this helped.
Answer:
<em>Dry suction chest tube system</em>
Explanation:
<em>The dry suction drains that are self-regulating today use a small, adjustable regulator installed into the drain. </em>
So long as there is enough air flow from the suction of the wall (that will be shown on the drain) it will respond correctly to changes in the pressure of the source or the patient to retain suction at the drain level.
It's also a quiet mode of activity.
