What is the normal to a line? The normal line to a curve at a particular point is the line through that point and perpendicular to the tangent. A person might remember from analytic geometry that the slope of any line perpendicular to a line with slope m is the negative reciprocal −1/m. How do […]
Why is the Ph of ethanol 7?
Why is the Ph of ethanol 7? Ethanol’s hydroxyl group causes the molecule to be slightly basic. It is almost neutral like water. The pH of 100% ethanol is 7.33, compared to 7.00 for pure water. This reaction is not possible in an aqueous solution, as water is more acidic, so that hydroxide is preferred […]

What is an example of chemical weathering by water?
What is an example of chemical weathering by water? Chemical Weathering From Water Chemical weathering occurs when water dissolves minerals in a rock, producing new compounds. This reaction is called hydrolysis. Hydrolysis occurs, for example, when water comes in contact with granite. Feldspar crystals inside the granite react chemically, forming clay minerals. What are the […]

How do you know what type of function it is?
How do you know what type of function it is? One method for identifying functions is to look at the difference or the ratio of different values of the dependent variable. For example, if the difference between values of the dependent variable is the same each time we change the independent variable by the same […]
