C. NaOH ammmonia is also an base but not as strong as NaOH
Every mole of MgCl2 reacts with 2 moles of KOH, therefore the 4 moles of KOH will only react with 2 moles of MgCl2, making it the limiting reagent and therefore KOH determines how much Mg(OH)2 is produced.
Glycerol attractive forces are great than water. The harder to break, the more energy is needed.
Answer: 13.9 g of
will be produced from the given mass of oxygen
Explanation:
To calculate the moles :

The balanced chemical reaction is:
According to stoichiometry :
7 moles of
produce = 6 moles of 
Thus 0.900 moles of
will produce =
of 
Mass of 
Thus 13.9 g of
will be produced from the given mass of oxygen
Answer:
Enzyme
Explanation:
An enzyme is an organic catalyst that speeds up a reaction but can be recovered unchanged.
Human lactase consists of 4092 amino acid groups and has a molar mass of about 280 000 u, so it has a complex structure.
