Organize types of equations that can express a chemical reaction. In

the second column, list the elements (words, coefficients, etc.) that

are used to create each equation. In the third column, rank each

equation from 1 to 3, giving a 3 to the equation that provides the most

information, and a 1 to the equation that provides the least

information.

a chemical reaction happens

explanation:

answer: a tank of height h is filled with water and sits on the ground. water squirts from a hole at a height y above the ground and has a range r. for two y values, 0 and h, r is zero. determine the value of y for which the range will be a maximum.

explanation:

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.
