Answer:

10. it increases the boiling point because it is a stone bond and will require much energy to break it.

11.So, to boil liquid water, all hydrogen bonds have to be broken and it requires a large amount of energy. This isn't the case in HF; all hydrogen bonds need not to be broken, and therefore a lesser amount of energy is required. So HF boils at a much lower temperature as compared to water even though F has high electronegativity but the force of attraction or the intermolecular is is weak

Campare and Conteast Physical and chemical properties.
I am Lyosha [343]

Answer:

Physical properties are changes in color, weight, mass, density, volume, whether it is freezing, tarnishing, boiling, etc. while chemical properties are changes in the compound of the object such as whether an object is/isn't flammable, affected by acid, it dissolves, ferments, rots, ignites in water, etc.

Explanation:

Physical property examples: a piece of steel is cut in half, a sugar cube is ground up into a powder, ice melts into water, clouds form in the sky, you mow the lawn, the water turned purple when you dropped red and blue dye in it, leaves grow in the spring, ethyl alcohol boils at 79° C, you cut apples up

Chemical property examples: pancakes cook on the griddle, fireworks explode in th sky, Alka-Seltzer gives off carbon dioxide when added to water, roasting a marshmellow, milk sours when left on the counter, burning wood in a bonfire, salt dissolves in water, food is digested in the stomach

This is not the best way to organize a periodic table because two elements might have similar atomic mass.

<h3>What is periodic table?</h3>

Periodic table is a chart in which arrangement of chemical elements are done.

In the early periodic table elements are arranged on the basis of their atomic masses, while after sometime Moseley arranged the periodic table on the basis of atomic number as he proposed that properties of an element is justified on the basis of number if electrons.

And mass of two substances may be same so it is difficult to differentiate between them.

Hence, two elements might have similar atomic mass.

What is the pH of a<br> 1.00×10-8M<br> KOH solution ?
SVEN [57.7K]

Answer:

the pH of the solution expresses the concentration of hydrogen ion in the solution. By measuring the pH value of a solution helps us to define the acidity or basicity of the solution. If the pH value in the pH scale is greater than 7 then the solution is basic
