Answer:
This is because their atoms have the same number of electrons in the highest occupied energy level. Li lithium and K potassium both belong to first group (alkali metals) and thus have similar chemical properties.
Explanation:
The reaction is
2H₂(g) + O₂(g) ---> 2H₂O
Thus as per balanced equation two moles of hydrogen will react with one moles of oxygen.
There is a directly relation between moles and volume. [One mole of each gas occupies 22.4 L of volume at STP]
Thus we can say that two unit volume of hydrogen will react with one unit volume of oxygen
Now as we have started with equal units of volume of both oxygen and hydrogen, half of oxygen will be consumed against complete volume of hydrogen
so the gas which will remain in excess is oxygen
A collision hypothesis that claims a chemical reaction can only happen when reactants collide at the right angle and with enough kinetic energy.
<h3>What in chemistry is a reactant?</h3>
A material that's also present at the outset of such a chemical reaction is known as a reactant. Products are the substrate(s) to the side of the arrow. A component that remains after a chemical reaction is finished is known as a product.
<h3>Which side are the products and reactants?</h3>
The chemicals (what you started with) be transformed into byproducts in a chemical process (what you end with). An arrow separates the reaction mixture, which are indicated on the left side of a solution, from the products, who are depicted on the right.

The correct order of increasing surface tension at a given temperature, CH(OH)CH₂ OH >CH₃CH₂CH₂OH>HOCH₂ CH₂ OH>HOCH₂
With higher intermolecular pressures, a molecule's surface tension rises. Here, every molecule that is there has a hydrogen bond. It is well known that as the number of O-H bonds in a given molecule increases, so does the degree of hydrogen bonding. Strong intermolecular forces are thought to exist in molecules with more H-bonds. Due to the hydrogen bonds between water molecules, it has the highest surface tension of any liquid, save for mercury. Water molecules near the liquid's surface that are in contact with air are held tightly together by surface tension to create an imperceptible film.

According to Avagadros law 1 mole of a substance contains 6.02 × 10^23 particles.
Thus, 1 mole of C6H14 contains 6.02 × 10^ 23 molecules,
Therefore, 9.25 × 10^24 molecules will have;
(9.25 × 10^24)/ (6.02 ×10^23)
= 15.365 moles.
