Solve for x in the following equation: 2x + 3 = 16x - 9
x is equal to 6/7. Work shown: 2x - 2x + 3 = 16x - 2x - 9 3 = 14x - 9 3 + 9 = 14x - 9 + 9 12 = 14x x = 12/14 which simplifies to 6/7
In the chemistry lab, there are many different sorts of instruments that we can use to understand which chemicals we are working with and producing. If you wanted to measure changes in concentration of a compound that gave off visible color wavelengths as opposed to wavelengths the human eye cannot see, which type of instrument would you most likely use?
I would use a ultraviolet visible spectrometer because this instrument can measure wavelengths of light produced in the ultraviolet and visible light spectrum. Such instruments are also very commonly used by chemical researchers and are not hard to find in a lab.

What is the trend of electronegativity when looking down a row of the periodic table?
When looking down the periodic table's rows, electronegativity of an element tends to increase. By understanding this trend we can say that oxygen is a more electronegative element than carbon.
