Explain why a 0.10 HCL solution is assumed to have a pH value 1?
HCl is a strong acid. Therefore, it can be expected to fully dissociate in aqueous solution, yielding one hydrogen ion and one chloride ion per molecule. The concentration of the hydrogen ion should thus be the same as the initial concentration of the HCl. Therefore, a 0.10M HCl solution has an H+ concentration of 0.10M. By the equation pH=-log[H+], the pH of this solution is 1.
Why does increasing the concentration of a reactants increase the reaction rate?
Because it increases the probability of collisions
Does absorbance increase or decrease as the solution concentration of the substance increase?
The light is absorbed at a specific wavelength and this is because the electrons in the chemical bonds only absorb certain wavelengths of light. So, more concentration, more bonds and more electrons to absorb the light.
How many molecule of hydrogen in 26 molecules of ammonia?
Each molecule of ammonia has three hydrogen atoms; therefore, 26 molecules of ammonia contain 26 X 3 = 78. However, these hydrogen atoms do not constitute hydrogen molecules, so the literally correct answer is zero.
Does the acid increase the concentration of hydrogen ions in the solution?
The pH increases. There are two ways to think about this. First, adding hydroxide ions is the same as adding a base, and a base will cause the pH of a solution to become more basic, i.e. increase. Second, hydroxide ions will react with hydrogen ions in the solution to neutralize them, decreasing the concentration of hydrogen ions. Since the pH scale is a negative logarithmic scale, a decrease in the concentration of hydrogen ions means an increase in pH.

Is carbon a water molecule?
No, water molecules are made of Hydrogen and Oxygen, there is no Carbon.
Is hydrogen a molecule?
Hydrogen is an atom but the hydrogen molecule is diatomic.H is a single Hydrogen atom, and H2 is a molecule.
Why does increasing the concentration of a reactants increase the reaction rate?
Because it increases the probability of collisions
Why is a hydrogen molecule an example of a molecule?
H2 is how the molecule of hydrogen is presented
Why is hydrogen peroxide polar?
Hydrogen peroxide is polar due to its angular shape. There are only two cases where a molecule is non-polar, which is when the molecule is pure covalent bond in linear or tetrahedral shape. Hydrogen peroxide is neither therefore it is polar.
When hydrogen bonds break what happens to energy?
energ y is absorbed by the molecule to increase its kinetic energy
Does absorbance increase or decrease as the solution concentration of the substance increase?
The light is absorbed at a specific wavelength and this is because the electrons in the chemical bonds only absorb certain wavelengths of light. So, more concentration, more bonds and more electrons to absorb the light.

How do an atom of hydrogen and a molecule of hydrogen differ?
A molecule consists of many atoms. When you have a hydrogen molecule, or whatever other type of molecule for that matter, you have many hydrogen atoms that make it.
Hydrogen bonding in water causes water to?
since the molecule has two bonds of the oxygen to the hydrogen, this cause the water molecule to be bent hence the electronegative does not cancel out. Therefore this makes the water molecule polar. It also shrink as temperature approaches 0C
Who is lightest Hydrogen or molecule?
