Answer:

A) 2Na + Br_{2} = 2NaBr

Explanation:

As the problem says that you should find the balanced chemical equation for the synthesis of NaBr from Na and Br_{2}, the reactants are Na and Br_{2} and the product is NaBr, so it can be writen as:

Na + Br_{2} = NaBr

Then you shoud balance the equation, it means that you should have the same number of each element in each part of the equation, so if you put a number 2 for the NaBr and the Na, the equation will be balanced:

2Na + Br_{2} = 2NaBr

Which statement is correct about the location of electrons in an atom according to the Quantum mechanical model? A) Electrons ar
katrin2010 [14]

Answer:

B) Electrons are located in the cloud-like areas around the nucleus.

Explanation:

The quantum mechanical model of the atom does not consider the path through which an electron travels. It rather estimates the probability of where electrons can be found at each energy level.

The region of maximum probability of where an electron is located is sometimes called an electron cloud or orbital. Each orbital of an atom and the electrons accomodated are described completely by a set of four quantum numbers.

How do oceanographers define salinity?
Studentka2010 [4]

The oceanographers define salinity by the number of grams of salt per kilogram of water.  

Salinity is illustrated as how much salt is present in the given amount of water. It is dependent upon how much salt is found in the ocean in the specific regions. If there is a sunny environment, it may evaporate an ample amount of water, and leave behind a lot of salt, thus, the water has more salinity.  

The salinity of the ocean is usually measured in Practical Salinity Unit (PSU), it is a unit based on the characteristics of seawater conductivity.
