The number 16 next to the elemental symbol of Nitrogen
which is N indicates the mass number of the element. Now the atomic number of N
is 7, this is also equal to the number of protons or electrons in the nucleus. So
the balance is 16 – 7 = 9 which is being occupied by the neutrons. Therefore
the number of neutrons is:

Answer:
2Cs+Sr(CrO4)-->Cs2(CrO4)+Sr
Explanation:
just set them equal, only value that changed was the amount of cesium(Cs)
<span>Like dissolves like and unlike repels like. This applies to the polarity of the solutions. Polar dissolves polar and non-polar does not mix with polar solutions. In this case, the polar substance that can mix with water. Sugar and salt can be dissolved through agitation. Oil which is nonpolar is immiscible in water. Hence answer is D. </span>
Answer:between 25 and 40 degrees Fahrenheit
Explanation:
Heat pumps do not operate as efficiently when temperatures drop to between 25 and 40 degrees Fahrenheit for most systems. A heat pump works best when the temperature is above 40. Once outdoor temperatures drop to 40 degrees, heat pumps start losing efficiency, and they consume more energy to do their jobs.
The equation that shows the formation of chromium (ii) ion from neutral chromium atom is as follow
Cr ---> cr^2+ + 2e-
Cr^2+ is the chromium ion with oxidation state of two which is one of the common ion of chromium. Other common ion of chromium include chromium of oxidation state 6 and 3
