Because if you know more about your solution it helps in the test or expidition.
The two properties you would want in a mercury thermometer are accuracy and precision. Accuracy is important because you want to know that it is recording the right temperature, and precision is important because it allows you to know the exact temperature to the extent of the gradations of that thermometer. Cherry flavor would be nice too! :)
The final pH would be less than 5 because the stronger acid (pH 4.0) would have a greater effect on the overall pH than the weaker acid (pH 6.0). To calculate the exact final pH, you would need to know the exact concentrations of the two solutions and perform a Henderson-Hasselbalch calculation.
Why are you or someone you know doing this?Why do you need solutions?If you or some one you know is then just stop,or give the puppy away.
You can't really know that in all cases. But with some practice in working with equations, you'll start to notice certain patterns. For example, you'll know that certain functions are periodic, and that an equation such as: sin(x) = 0 have infinitely many solutions, due to the periodicity of the function. This one is easy; we can make some small changes: sin(2x + 3) = 0.5 Here it isn't as easy to guess the exact solutions of the equation, but due to our knowledge of the periodicity of the sine function, we can assume that it has infinitely many solutions. Another example: a single equation with two or more variables normally has infinitely many solutions, for example: y = 3x + 2
It depends on the concentrations (H2SO4 at 1.5M is considered corrosive). Assuming however that the two solutions are of the same concentrations, the answer would be sulpuric acid. Apart from causing acid burns, H2so4 (Sulphuric Acid) reacts exothermically with water. As you probably know, the human body is composed much of water, so apart from just acid burns, thermal burns are also likely to be inflicted on the poor person.
TRUE
Concentrations in molality (moles of solute per kilograms of solvent) are independent of temperature and pressure whereas concentrations in molarity (moles of solute per total volume of solution in liters) are not.
Factorise it!

The homophone of "no" is "know."
The most desirable characteristic would be its effect on sales and brand perception. As far as specifics, it'd be helpful to know whether you are marketing to the medical industry or to consumers.
The number of moles of silver chromate formed will depend on the stoichiometry of the reaction between silver nitrate and potassium chromate. You need to know the balanced chemical equation, as well as the exact volumes and concentrations of the silver nitrate and potassium chromate solutions to calculate the number of moles of silver chromate formed.
