What else can I help you with?
True or false As the concentration of a colored solution increases the absorbance value decreases?
Absorbance rises with concentration because there is more material for a given frequency of light to be absorbed in. Your statement is false.
Is it possible to have a concentrated solution of a weak acid or base True or False?
True. It is possible to have a concentrated solution of a weak acid or base, as the concentration of a solution refers to the amount of solute dissolved in a solvent, regardless of the strength of the acid or base. The degree of dissociation may be low, but the concentration can still be high.
Distilled water is about the only completely neutral solution. What is its pH?
Almost anything - its not buffered. (Your first statement is false)
Is it true that An acidic solution has a very high concentration of OH ions?
No it is false -it has a high concentration of H+ ions
The of an acid and a base is determined by how completely they dissociate in water?
The _____________ of an acid and a base is determined by how completely they dissociate in water. strength
The concentration of an acid or base refers to?
False
True or false As the concentration of a colored solution increases the absorbance value decreases?
Absorbance rises with concentration because there is more material for a given frequency of light to be absorbed in. Your statement is false.
In television share refers to artists appearing on different shows?
False
Overdubbing refers to too much dubbing true or false?
false
The concentration of hydrogen ions in solution is the pH of the solution the answer has to be either true or false?
True. The concentration of hydrogen ions in a solution directly determines the pH of the solution. A lower concentration of hydrogen ions results in a higher pH, while a higher concentration of hydrogen ions results in a lower pH.
Energy is always required to force molecules to move from areas of high concentration to areas of low concentration true or false?
False. Energy is not required to move molecules from areas of high concentration to areas of low concentration; this process occurs naturally through diffusion, which is driven by the concentration gradient. However, energy is required for active transport, where molecules are moved against their concentration gradient from low to high concentration.
Is diffusion an active mechanism?
False
Did the concentration of wealth decreased substantially in the last two decades?
false
Is vms real?
nope it's completely false.
Is this true or false in nature vs nurture is nurture considered to be genetics?
False. Nature refers to genetics, nurture refers to environmental conditions.
True or false in a cell that has an abundance of substrate does increasing the enzyme concentration will not affect the number of reactions occurring in the cell?
False
True or false. cultivation refers to the number of organisms a piece of land can support?
False
