Chemistry
1 answer:
S_A_V [24]3 years ago
3 0

Answer:

Synthesis - 4

reversible- 2

exchange- 1

decomposition-3

Explanation:

In synthesis reaction two or more components combines to form a single product. example 2H2+O2⇒2H2O

In reversible reaction two reactants combine to form two products . The products then reacts and forms back the reactants. example N2 +3H2 ⇒2NH3

In exchange reaction there is an alternation of ions of reactants to form new products. AB+CD ⇒AC + BD

In decomposition reaction, molecules of a compound break down by the action of heat or light or catalyst. example CaCO3 ⇒CaO +CO2

Partial charges will exist on each atom when a bond exists between two atoms with different electronegativities. Since the atom
lana66690 [7]

Answer:

negative, positive, increase

Explanation:

From the given question,  

During the formation of bond, between two atoms with difference between their electronegativity-

  • The more electronegative atom, will pull the electrons towards itself , and hence acquires a partial negative charge,

And,

  • The less electronegative atom, will acquire a partial positive charge.
  • The more the difference between the electronegativity of the atoms, the more would be the magnitude of partial charge.
  • And, the less would be the difference between the electronegativity of the atoms, the lesser would be the magnitude of partial charge.

Predict whether each of the following molecules is polar or non-polar:a) IF,b) CS2, c) SO3, d) PCl3, e) SF6, f) IF5.
BlackZzzverrR [31]
<h3><u>Answer;</u></h3>

Polar: IF, PCl3, IF5  

Nonpolar: CS2, SO3, SF6

<h3><u>Explanation:</u></h3>
  • Polar molecules form when two atoms do not share electrons equally in a covalent bond.
  • A molecule is classified as a polar molecule when the arrangement of the atoms is such that one end of the molecule has a positive electrical charge and the other end has a negative charge.
  • A non-polar molecule does not have electrical poles.The electrons are distributed more equally.
  • Therefore, a non-polar molecule does not have a profusion of charges at the opposite ends. The majority of hydrocarbon liquids are non-polar molecules.

Bonds between metals and nonmetals tend to be ionic, but bonds between nonmetal atoms tend to be covalent. Explain why this is t
Assoli18 [71]
Ionic bond is a type of bond in which one or more atoms are transferred to another atom which results to two ions with opposite charge. They attract each other.

The atom of another element is removed and then gained by another element which produces a noble gas electron configuration.

Covalent bond is a type of bond in which a pair or more electrons are being shared by the atoms of two elements.

Because of this, the molecules become stable by sharing the electrons thus creating a noble gas configuration for each of the atom.
