Answer:
37.3g
Explanation:
Formula of the compound:
FeCl₃
Number of chloride ions = 4.13 x 10²³ ions
First find the number of moles in this ions;
6.02 x 10²³ ions are contained in 1 mole of a substance
4.13 x 10²³ ions contains = 0.69mole chloride ions
Now;
3 mole of chloride ions are contained in 1 mole of FeCl₃
0.69 mole of chloride ions will contain = 0.23mole of FeCl₃
To find the mass;
Mass of FeCl₃ = number of moles x molar mass
molar mass of FeCl₃ = 55.8 + 3(35.5) = 162.3g/mol
Mass of FeCl₃ = 0.23 x 162.3 = 37.3g

Explanation:
Answer:
- The condensation reaction that forms nucleic acid polymers occurs between a <u><em>Phosphate</em></u> group on one nucleotide and a <u><em>hydroxyl group of sugar</em></u> on a second nucleotide.
Explanation:
- When nucleotides polymerize to form nucleic acids, the hydroxyl group attached to the 3′ carbon of a sugar of one nucleotide forms an ester bond to the phosphate of another nucleotide, eliminating a molecule of water.
Summary:
So the phosphate group of one nucleotide form bond with the hydroxyl group of an other nucleotide with the elimination of water molecules.
answer= 0.5
explanation=
Carbon has a relative atomic mass of 12.
Oxygen has a relative atomic mass of 16.
12+(2x16)=44
Therefore 1 mole of CO2 has a relative atomic mass of 44.
22/44=0.5, so there is half a mole of CO2 in 22g of it
Answer:
1. H+ + OH- <--------> H2O
H+ is a Lewis acid
OH- is a Lewis base
2. Cl- + BCl3 <---------> BCl4-
Cl- is a Lewis base
BCl3 is a Lewis acid
3. K+ + 6H2O <------> K(H2O)6+
K+ is a Lewis acid
H2O is a Lewis base
Explanation:
By definition, Lewis acid is an electron pair acceptor while a Lewis base is an electron pair donor.
Potassium ion accept electron pairs from 6 water molecules which donate the electron pairs.
