How do you know if the discriminant is negative?
You calculate the value of the discriminant. If the answer is less that zero, that is, if the answer has a minus sign in front then it is negative.
How do you calculate the height of a triangle if I know the length of each side?
A squared. + b squared = c squared.
4x plus 3 equals?
We don't know and we can't calculate it, until the value of 'x' is given.
What may be calculated from its diameter?
If by "it" you mean a circle, once you know the diameter, you can calculate its radius, its circumference, and its area.
How do you find the slope of a parallel line?
Parallel lines have the same slope. So if you know the slope of a line in question, or you can calculate it, then you know the slope of any line parallel to that line.
What two things must you know about density?
In order to calculate the density of a substance, you must know the volume and the weight of a sample. Then the density is calculated as Density = (Weight) divided by (Volume).
What formula can you use to calculate the H3O plus?
In an aqueous solution, the concentration of H3O+ is the same as the concentration of H+. If you know the pH of the solution, then that's equal to 10^(-pH).
How do you calculate concentration factor in chemistry?
You need to know density and percent by weight. Then use the following formula: ((1000)density x % by weight) / formula mass=concentration
Ph value of sodium hydrogen carbonate?
Alkaline, but you need to know the concentration and the dissociation constant to calculate pH
What can you calculate if you know the concentration of a reaction's products and reactants as well as the coefficients of each in the balanced equation?
the equilibrium constant
Can you calculate a perimeter of a rectangle but not the length of its sides?
no No. You need to know the length of a rectangle's sides in order to calculate the perimeter.
How do you derive pH values for weak acids?
Every acid has a constant, called the acid dissociation constant(or Ka), which shows how much the acid dissociates to form ions in water.For an acid, the general dissociation equation is:HA -------> H+ + A-Ka = (concentration of H+) times (concentration of A-) divided by (concentration of HA)The values for concentrations are the values AT EQUILIBRIUM, where the concentrations of all three substances remain the same.If HA was a strong acid, it would completely(or almost completely) ionize in water to form its ions. Therefore, you can say that the concentration of H+ ions in the solution equal the concentration of HA. From this, you can calculate the pH by using the formula pH = - log (H+).If HA was a weak acid, however, things would be different. The acid only partially ionize in water, so you cannot say that the concentration of H+ is equal to the concentration of HA.If you know the value of the acid dissociation constant, you can easily find the concentration of H+ in the solution, and in turn calculate the pH.You know that the amounts of H+ and A- are equal. If you know the concentration of the acid HA you put in, you can calculate the H+ .
How do you calculate angle bar weight?
In order for your to know the weight must know the thickness of the angle bar.
What is the process of standardization?
Standardization is a term that can be used in many fields. A chemist would use standardization when trying to figure out the concentration of an unknown solution. They need to know the specific concentration of one of the solutions so they can calculate the other unknown concentration. Many acid-base reactions use this technique. They perform a series of repeatable tests with a third chemical solution that never varies in concentration. They can then calculate the one concentration and use it in their experiment to determine the other concentration. This set of tests is known as standardization of a solution.
How is distance and time alike?
You need to know both of them in order to calculate speed.
What is the answer to 4a minus 4 equals?
You would need to know what a is equal to in order to calculate this equation.
How do you calculate mineral contents of the sample?
We would need to know what sample you are referring to in order to answer this question.
