Answer:
number of hydrogen atom in 1.8 mole of NH2OH = 
Explanation:
percentage of hydrogen in NH2OH = mass of hydrogen / mass of whole molecule
=
\times 100
= 9.09 percentage
therefore number of moles in 1.8 moles of hydroxy amine = 
= .16 moles of hydrogen
number of hydrogen atom = (number of moles )×(avagadro number)
= atoms of hydrogen

1. Salivary amylase ---- substrate: Starch ---- end-product: Maltose
2. Lipase ---- substrate: Lipids (fats and oils) ---- end-product: Fatty acids and glycerol
3. Maltase ---- substrate: Maltose ---- end-product: Glucose
4. Protease ---- substrate: Protein ---- end-product: Amino acids
Answer:
Ag(I)C2H3O2 ....................
Silver only has a single valence value (+1) so you really don't need to put the (I) in the chemical formula.
Answer: Most polyatomic ions are -ate, related ions that have 1 fewer oxygen atom are -ite (must have at least 1 oxygen tho) and nonmetals are ide.
Explanation:
Answer:
Reha should apply 540 N to lift Neha.
Explanation:
L = 360 N
LD = 60 m
E =?
ED = 40m
NOW
L * LD = E * ED
360 *60 = E*40
21600/40 = E
540 N = E
