When 100.0 mL of 1.000 M HCl is reacted with 100.0 mL of 1.000 M NH4OH, the solution’s temperature increases 7.01 °C. Calculate LaTeX: \DeltaΔHreaction in units of kJ/mol. The specific heat of the salt solution is 4.184 J/g-°C and the density is 1.010 g/mL. Do not use units or labels in answer. Make sure answer has the correct sig figs.

Explanation:

volume of solution = 100 + 100 = 200 mL

mass of reaction mixture = 200 x 1.010 = 202 g

specific heat of solution mixture = 4.184 J/g-°C

heat evolved = mass x specific heat x rise in temperature

= 202 x 4.184 x 7.01

= 5924.63 J

100 mL of 1 M HCl

= .1 L of 1M HCl will contain .1 mole of HCl

.1 mole reacts with .1 mole of NH₄OH to make 5924.63 J of heat

1 mole reacts with 1 mole of NH₄OH to make 59246.3 J of heat

heat of reaction = 59246.3 J / mol

= 59.246 kJ / mol

= 59.3 kJ / mol .

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.
