Answer:
A. Hund's rule has been violated
Explanation:
There must be one electron with the same spin in each orbital of the same energy before you can put two in the same orbital. In the photo, the 2s sublevel is completely filled before the 1s sublevel (if anything the 1s should have an up spin and down spin, with the 2s having one up spin).
Answer:
True
Explanation:
Cell specialization is the process by which generic cells change into cells meant to do certain tasks within the body
hope this helps :)
Depending on the testing process being used, it may affect the object by making it shape differently, scratch, it or sometimes do absolutely nothing. hope this helps:)
False. A buffering solution consists of a WEAK acid such as CH3COOH, C5H5N, or ammonia. <span>A buffering solution resists pH change upon the addition of an acidic or basic components. It can neutralize little amounts of added acid or base, thus maintaining the pH of the solution relatively stable. The correct answer is letter "B. false"</span>
<u>Answer:</u> The equilibrium constant expression for the given equation is written below.
<u>Explanation:</u>
Equilibrium constant in terms of partial pressure is defined as the ratio of partial pressures of products to the partial pressures of reactants each raised to the power their stoichiometric ratios. It is expressed as 
For the general chemical equation:
The expression of 
follows:
For the given chemical equation:
The expression of for above equation follows:
Hence, the equilibrium constant expression for the given equation is written above.
