What is the question exactly?
The total heat considering both the sensible and latent heat is expressed by ΔH = (m Cp ΔT)solid + (m ΔHv) + (m Cp ΔT<span>)liquid.
Subsituting the data to the equation,
</span>ΔH = (10 g *2.09 J/g K *25 K) + (10 g *80 cal/g *4.1858 J/cal) + (10 g* 4.18 J/gK * 90 K<span>)
</span>ΔH = 7633.14 Joules
Weathering definition= <span>wear away or change the appearance or texture of (something) by long exposure to the air.
Erosion definition= </span><span>the process of eroding or being eroded by wind, water, or other natural agents.
Deposition definition= </span>the action of deposing someone, especially a monarch.
these definitions are out of my textbook but in my own words.
The molarity of a solution prepared by dissolving 141.6g of citric acid in water is calculated as below
find the the number of moles
moles= mass/molar mass
= 141.6 g/ 192 g/mol = 0.738 moles
molarity= moles/molar mass
= 0.738/3500 x1000 = 0.21 M
