Answer:- The direction of the polarity of the indicated bond is from carbon to oxygen.
Explanations:- There are two types of covalent compounds, polar and non polar. If the bond is between two same atoms for example, H-H, Cl-Cl etc then the bond is non polar. If the bond is between two different atoms then the bond would be polar. The direction of the polarity is from loss electron negative atom to more electron negative atom.
Oxygen is more electron negative than carbon. So, being more electron negative, the bonding electrons are more towards oxygen and it cases partial negative charge on oxygen and partial positive charge on carbon. The direction of the polarity is from less electron negative carbon to more electron negative oxygen.
It is shown in the diagram below:
Answer:
g. H₂SO₄ + Ca(OH)₂ → CaSO₄ + 2H₂O.
Explanation:
Sulfuric acid is represented as H₂SO₄ and calcium hydroxide is represented as Ca(OH)₂.
- To balance a chemical reaction. we should apply the law of conservation of mass that the no. of different atoms in both sides (reactants and products).
- The only choice that represent the reactants correctly and apply the law of conversation of mass is:
<em>g. H₂SO₄ + Ca(OH)₂ → CaSO₄ + 2H₂O.</em>
<em></em>
<em>f. H₂SO₄ + 2Ca(OH)₂ → 2CaSO₄ + 3H₂O </em>
is not correct that the no. of S, and O is not equal in both reaction sides.
S in reactants (1) while in products (2).
<em>O in reactants (8) while in products (11).</em>
<em></em>
<em>h. HSO₄ + CaOH → CaSO₄ + H₂O</em>
The reactants is represented in a wrong way.
<em> j. H₂SO₄+ Ca(OH)₂ → CaSO₄ + H₂O</em>
is not correct that the no. of H and O is not equal in both reaction sides.
H in reactants (4) while in products (2).
O in reactants (6) while in products (5).
<em></em>
<em>So, the right choice is: g. H₂SO₄ + Ca(OH)₂ → CaSO₄ + 2H₂O.</em>

The two molecular characteristics of substances that typically form liquid cyrstals and there phases are long, cylindrical shape and between molecules & strong intermolecular forces exist
All these enables different application of liquid crystals

A three dimensional circular shape would be a sphere :)
Hope you find this answer I need points
