hydrogen, oxygen, potassium, calcium, nitrogen, sodium
Answers
Answer:
The correct option is C
Oxygen
Carbon
Hydrogen
Nitrogen
Sulfur
Phosphorus
Explanation:
Oxygen is considered to be the most abundant element to be found in the living cells. Usually, a living cell is made up of 65% oxygen.
Carbon is the element which forms the basis for life for all organisms which can be seen on the planet Earth.
Hydrogen combines with oxygen to form water which makes up 65 percent of the human body.
Nitrogen is an active constituent of molecules such as proteins which are of utter importance to an organism.
Phosphorus is present in the form of phospholipid layer which is an active constituent of the cell membranes.

548.55 grams of aluminum hydroxide should theoretically form.
Explanation:
Balanced equation for the reaction:
3 NaOH + Al ⇒ Al(OH)3 +3 Na
DATA GIVEN:
mass of NaOH = 842 grams, atomic mass =39.9 grams/mole
mass of Al = 750 grams, atomic mass = 26.9 grams/mole
aluminum hydroxide theoretical yield = ?
Moles of NaOH reacted
number of moles =
putting the values in the equation
NaOH =
= 21.1 MOLES OF NaOH
Al =
= 27.8 moles
from the equation
from 3 moles of NaOH 1 mole of Al(OH)3 is produced
21.1 moles of NaOH will react to give x moles of Al(OH)3
=
7.03 moles of Al(OH)3 is formed.
and
1 mole of Al(OH)3 is formed from 1 mole of Al in the reaction
so, 27.8 Moles will react to give give 27.8 moles of Al(OH)3 limiting reagent of the given reaction is NaOH
mass of Al(OH)3 =7.03 x 78 (atomic mass of Al(OH)3)
= 548.55 grams
theoretical yield from the given data is 548.55 grams

Answer:
some bonds are broken and new ones are formed. Now you are ready to learn more about those bonds. Chemical bonds are attractions between atoms. They are simply attractive forces (between the + nucleus of one atom and the - electrons of a neighboring atom) that hold groups of atoms together and make them function as a unit.
