Decompostion reaction have the general chemical reaction of: AB = A + B while synthesis reactions are of the general equation A + B = AB. These reaction can be the reverse of each other because ones building a compound (synthesis) and ones breaking down a compound (decomposition). For example, when reacting carbon and oxygen for a synthesis reaction we have: C + O2 = CO2 and for a decomposition reaction we have: CO2 = C + O2. Thus, these two reactions are the reverse of each other.
Answer:
An experiment is a research method performed within a completely controlled environment that uses groups of individuals ( subjects), one of which the factors being tested are not spplied on, an independent factor of the hypothesys ( to be tested ), for example the resilience of a group of teenagers) and a dependant factor that is applied to check how it varyes depending on the tested factor ( for example, the most challanging experience of their generation)
Your answer would be the solute in the ocean water. Hope this helps!
The Answer is "None of the Above"
Answer:
0.879 mg
Explanation:
To solve this problem we need to use the definition of ppm:
- ppm = μg solute / g solution
With the above information in mind we can calculate the micrograms of lead using the concentration (13.97 ppm) and mass of solution (62.9 g):
- μg lead = 13.97 ppm * 62.9 g
Finally we convert μg to mg:
- 878.713 μg *
= 0.879 mg of lead
