Answer:
Exothermic
Explanation:
Exothermic reactions release heat, endothermic absorb heat, and precipitate is a solid formed from a solution
<span>Given that a one mol solution of lithium chloride has 0.0900 mol of lithium chloride dissolved in it. Which implies that 0.910 mol of water has dissolved 0.0900 mol of Lithium chloride. which implies 0.910*18g of water has 0.0900mol LiCl.
Molality is given by moles of solute divided by kg of solvent.
so 1 kg of water has (0.0900*1000)/(0.910*18) mol of LiCl.
or 5.4945 molal solution.
So molality is 5.4945</span>
Answer:
24.45 L
Explanation:
From General gas equation,
PV/T = P'V'/T'.................... Equation 1
Where P = initial pressure, V = Initial volume, T = Initial Temperature, P' = Final pressure, V' = Final Volume, T' = Final Temperature.
make V' the subject of the equation.
V' = PVT'/(TP')................. Equation 2
Given: P = 760 torr, V = 22.4 L, T = 0 °C = (0+273) = 273 K, T' = 25 °C = (25 + 273) = 298 K, P' = 760 torr
Substitute into equation 2
V' = 760(22.4)(298)/(760×273)
V' = 24.45 L.
Hence the volume of the gas = 24.45 L
