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

A metal cylinder has a mass of 128g. When the cylinder is submerged into water, it displaces 424ml of water. Calculate the speci
Colt1911 [192]
First, we will need to find the density of the object, take the mass and divide it by the dispplaced water:
128/424 = 0.302 grams/milliliters 
Convert that to kg/m3
We get: 302kg/m3
Divide that to the density of water: 1000kg/m3
302/1000 = 0.302 
(thats a pretty darn light weighted metal)
