A547-mlml sample of unknown hcl hcl solution reacts completely with na2co3na2co3 to form 17.1 gg co2co2. what was the concentration of the hclhcl solution?

the required concentration is 1.52 M

2 HCl + Na2CO3 > CO2 + H2O + NaCl

2 moles HCl reacts to form 1 mole of CO2 .

no. of moles of CO2 = 20.1/ 44.1 = 0.455

no. of moles of HCl = 0.455* 2 = 0.911 mole (molar ratio =2 from equation)

con. of HCl =no. of moles/volume in liter

=0.911/ 0.597 = 1.52 M

one state would change   like louisiana to texas. thats a change

explanation:

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.
