Answer:
1 mole is equal to 1 moles Potassium, or 39.0983 grams.
39.0983g X 4 = 156.3932
so 4 moles are in 156 grams of Potassium

Dipole-induced dipole forces.
In contrast to C2H5OH, which is a very polar molecule, bromine is non-polar and has zero dipole moment. Charges are separated within polar molecules.
When a nonpolar Br2 molecule interacts with a polar C2H5OH molecule, one half of the bromine molecule acquires a charge and the other half acquires an opposing charge. A dipole is created when two adjacent bromine molecules have different charges. Bromine molecules must thus overcome the intermolecular forces—also known as dipole-induced dipole forces—that form in order to dissolve in ethanol.

<span>How many mm are equal to 21 L?
1 L = </span>1000000 mm
Convert:-
1000000 × 21 = <span>21000000
21 l = </span><span>21000000 mm
</span><span>How many mg are equal to 9 g?
1 g = 1000 mg
Convert:-
9 </span>× 1000 = 9000
9 g = 9000 mg
3. Ca(OH)₂ + H₂SO₄ → CaSO₄ + 2 H₂O represents a neutralization reaction.
<u>Explanation:</u>
Neutralization reaction is a reaction in which an acid reacts with a base to form a slat and water.
First reaction is the decomposition reaction in which the reactant is decomposed to form 2 or more products.
Second one is the combustion reaction in which methane is burnt in presence of oxygen.
Third one is the Neutralization reaction, in which calcium hydroxide (base) reacts with sulfuric acid (acid) to form a (salt) calcium sulfate and water.
Fourth reaction is nothing but the double displacement reaction in which the ions exchanged their positions there by forming two new products.
