Answer:
Explanation:
Here, a balance between attraction between nucleus and electrons, and electron-electron, and nuclei-nuclei repulsion play role.
All chemical bonds are formed by overlapping of orbitals. If the electronegativity of the two elements forming the bond is very different (elements from the 1st ,2nd groups with elements of 7th group) then ionic bond are formed. If the electronegativities are more similar, then overlapping is stronger, and covalent bonds are formed.

Answer:</h3>
Mole ratio of D to A is 1 : 4
<h3>
Explanation:</h3>
We are given the generic chemical equation;
4A + B → C + D
We are supposed to determine the mole ratio of D to A
What is mole ratio?
- Mole ratio is the ratio of the number of moles of reactants or products in a chemical reaction.
- We determine the mole ratio using the coefficients of reactants or products in question.
For example;
- In the equation, 4A + B → C + D, the coefficient of A is 4 while the coefficient of D is 1.
- This means, 4 moles of A reacts with 1 mole of b to produce 1 mole of C and 1 mole of D
- Thus, mole ratio of D to A is 1 : 4
Answer:
Pi bond
Explanation:
Pi bond is the type of covalent bond which results from formation of molecular orbital by the side-to-side overlap of the atomic orbitals along the plane perpendicular to the line which connects nuclei of the two atoms in which the bond is formed. It is denoted by symbol π.
The bond is not symmetrical to the internuclear axis and on rotation the axis, the bond breaks.
The maximum number of moles of Nickel Carbonate (NiCO₃) that can form during a precipitation reaction is 0.025 mol. Hope this helped and have a great day!
