Answer:
ester C6H5CH2OC2H5 is formed.
Explanation:
C6H5CH2OH + C2H5OH ---> C6H5CH2OC2H5 + H2O
In the modern periodic table the elements are arranged in order of increasing atomic number.
Answer:
2 is the answer
Explanation:
Si: 1s2 2s2 2p6 3s2 3p2
Number of the unpaired electron will be 2
question 1
by use of Avogadro law
that is,1 mole = 6.02 x10^23 atoms
what about 0.60 moles
by use of cross multipication
=(0.60 mole/ x 6.02 x10^23)/ 1mole = 3.612 x10^23 atoms of Zn
question 2
by use of Avogadro law constant
that is 1 mole =6.02 x10^23 molecules
what about 3.52 x10^24 molecules
by cross multiplication
=( 1 mole x3.52 x10^24 molecules/6.02 x10^23 molecules) = 5.847 moles of water
question 3
by use of Avogadro law constant
1 mole = 6.02 x10^23 atoms
what about 2 moles =? atoms
by use of cross multiplication
=( 2moles x 6.02 x10^23 )/1mole= 1.204 x10^24 atoms of Li
question 4
by use of Avogadro law constant
1 mole = 6.02 x10^23 atoms
what about 6.02 x10^23 atoms =? moles
cross multiplication
(1 mole x6.02 x10^23 atoms)/(6.02 x10^23 atoms)= 1 mole of carbon
question 5
by use Avogadro law constant
1 mole =6.02 x10^23 molecules
what about 4.9 x10^23 moles =? moles
by cross multipication
=( 1mole x 4.9 x10^23 molecules) /6.02 x10^23 molecules = 0.81 moles ZNCl2
