Assume that 8.5 L of iodine gas (I2) are produced at STP according to the following balanced equation:
2 KI (aq) + Cl2 (g) → 2 KCl (aq) + I2 (g)

a. How many moles of I2 are produced?

b. How many moles of KI were used?

c. How many grams of KI were used?

its mg hope this

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.

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.
