It depends on the temperature. At standard freezer temperatures, a solution of 15 percent alcohol is likely to freeze. Alcohol has a lower freezing point than water, so the exact temperature at which it freezes will depend on the specific type of alcohol used.
In a 1M solution of glycerol, there will be 1 mole of glycerol in 1 liter of solution. One mole of glycerol contains approximately 6.022 x 10^23 molecules. Therefore, there are approximately 6.022 x 10^23 molecules of glycerol in 1 liter of a 1M solution.
To find the volume of KOH solution needed, use the equation: M1V1 = M2V2 where M1 = 0.22 M, V1 = 23 mL, M2 = 0.12 M, and V2 is the volume of KOH solution needed. Rearranging the equation gives: V2 = (M1 × V1) / M2 = (0.22 M × 23 mL) / 0.12 M = 42.33 mL Therefore, 42.33 mL of the 0.12 M KOH solution is needed to react with 23 mL of 0.22 M HCl.
Room temperature is commonly considered to be around 20-25 degrees Celsius. To convert 23 degrees Celsius to Kelvin, you simply add 273.15 to get 296.15 Kelvin, which is approximately equivalent to room temperature.
The change in temperature is ΔT = 191°C - 23°C = 168°C. The heat energy Q required is given by the formula Q = mcΔT, where m is the mass, c is the specific heat, and ΔT is the temperature change. Plugging in the values: Q = 2.4 kg * 1.75 cal/(g°C) * 168°C = 7056 cal = 7.056 kcal.
(X - 23)2= X2 - 46X + 529==============Not a solution but an expanded expression.(X - 23)(X - 23)------------------------Distribute by FOIL for above quadratic expression.
-23+7=-16
The square roots of 529 are -23 and +23.
To find the temperature that is 23 degrees less than 8°F, you subtract 23 from 8. This calculation gives you 8 - 23 = -15°F. Therefore, the temperature that is 23 degrees less than 8°F is -15°F.
