They are kind of opposite processes. Chemical synthesis is execution of chemical reactions to make products. Like you take two substances, you put them together, they react and you have new a substance. For example.
here Sodium and Chlorine react to make a new substance which is Sodium Chloride.
Chemical decomposition is process of seperating a substance to different substances. There is a substance by a reaction this substance becomes two substances, Like : XY -> X+Y For example :
Answer:
Natural nuclear disintegration.
Explanation:
This is because it cannot be managed, like it needs no energy particle yo occur, so its natural for helium to decay.
But it is nuclear because helium decays to release an energy particle (Beta particle).
The answer is B. <span>The individual trials and the averages should each have their own columns in the data table.
In an experiment, you want to be able to see all of the data, so you should always include the data from each individual trial; however, it's important to have a separate column for averages, so you are able to compare all of the data.
Hope this helps! :)</span>
Answer:
We have to add 17.2 grams of aluminium bromide
Explanation:
Step 1: Data given
Molarity of the aluminum bromide solution = 0.215 M
Volume = 300 mL = 0.300 L
Molar mass aluminium bromide = 266.69 g/mol
Step 2: Calculate moles Aluminium bromide
moles AlBr3 = volume * molarity
Moles AlBr3 = 0.300 L * 0.215 M
Moles AlBR3 = 0.0645 moles
Step 3: Calculate mass aluminium bromide
Mass aluminium bromide = moles AlBr3 * molar mass AlBr3
Mass aluminium bromide = 0.0645 moles * 266.69 g/mol
Mass aluminium bromide = 17.2 grams
We have to add 17.2 grams of aluminium bromide
