Answer:
The chemical equation can be written as:
2Mg+O
2
→2MgO
48 g of Mg reacts with 32 g of O
2
.
Thus, 4.8 g of Mg reacts with 3.2 g of O
2
.
Now, 32 g of O
2
forms = 80 g of MgO.
3.2 g of O
2
produces =
32
80
×3.2 = 8 g of MgO.

The list and discussions are stated below:
Explanation:
Good Laboratory Practice (GLP) is extremely important.
1. Organization
With GLP we can guarantee an organized work environment, which is essencial in a laboratory.
2. Safety
GLP promotes laboratory safety for personell, avoiding unecessary risks and preventing accidents.
3. Quality control
GLP ensures that experiments made and products developed in a laboratory have the demanded quality.
4. Reliability of results
GLP promotes quality of results reporting, wich directly influences the reliability of results.
CaCl2 + H2O are produced when HCl react with Ca(OH)2
Explanation
equation for reaction is as follows
Ca(OH)2 + 2HCl → CaCl2 +2H2O
1 mole of calcium hydroxide (Ca(OH)2 reacted with 2 moles of hydrochroric acid (HCl) to form 1 moles of calcium chloride CaCl2 and water H2O. This type of reaction is known as neutralization reaction since it between an acid (HCl) and a base (Ca(OH)2
Answer:
9.3 x 10^ -5 in standard notation is 0.000093
Explanation:
Since 10 is raised to a -5, this means that there should be 5 zeros before the non-zero digits
That would be an amino acid. The
and -COOH is the functional group for a carboxylic acid hence AMINO ACID.
