Chemistry

OLga [1]3 years ago

Answer:

CH3CHO+H2O → CH3OCH3 - addition

CH,CICH CI + Zn → C2H4 + ZnCl2 - elimination

CH3CH3Br + OH – CH3CH3OH + Br - substitution

2CH2COOH >>(CH3CO)20 + H20 - condensation

Explanation:

An addition reaction is a reaction in which a specie is added across the double bond as we can see in CH3CHO+H2O → CH3OCH3.

In an elimination reaction, a small molecule is lost from a saturated compound to form the corresponding unsaturated compound as in CH,CICH CI + Zn → C2H4 + ZnCl2

In a substitution reaction, a chemical moiety replaces another in a molecule as in; CH3CH3Br + OH – CH3CH3OH + Br .

A condensation reaction is in which two molecules are joined together to form a bigger molecule as in; 2CH2COOH >>(CH3CO)20 + H20.

Fill in the blanks to complete the table
aleksandrvk [35]

The atomic number(Z) is equal to the number of protons to equal to number of electrons.

The number of neutrons is equal to atomic mass minus the atomic number

n=A-Z

For Zn^2+, Z=28, e=28

For iron, Z=25,A=55

The number of neutrons is 55-25=30

The charge is zero

For O^2-, Z=8+2=10, n=p=10

The number of neutrons is 16-10=6

For sulfur, Z=16,A=34

For S2-, Z=16+2=18, A=34

The charge is 2-

  • The atomic number is the basis of the periodic table.
  • It is equal to the number of protons.
  • The number of neutrons is atomic mass minus atomic number.

Consider the formula for glucose: C6H12O6. What does this indicate about the relationship of the reactants to glucose?
stellarik [79]

The correct option is D.

The reactants that combine together to form glucose are carbon dioxide, water and energy from the sun. Six molecules of carbon dioxide combine with six molecules of water in the presence of sunlight to form glucose. The chemical equation for the reaction is given below"

6CO2 + 6H2O + Sunlight = C6H12O6.
