The enthalpy of fusion of methanol (ch3oh) is 3.16 kj/mol. how much heat would be absorbed or released upon freezing 25.6 grams of methanol?

5.04 kJ

Explanation:

We are given the enthalpy of fusion of methanol as 3.16 kJ per mol of methanol. Thus, what we need is to determine is the number of mol in 25.4 g of methanol and multiply by this enthalpy.

mol methanol = mass / MW CH₃OH = 25.6 mol / 16.04 g/mol = 1.60 mol

ΔH = 1.60 mol x 3.16 kJ/mol = 5.04 kJ

answer; i believe the correct answer is (c) /// is a homogeneous mixture of gaseous substance nitrogen,oxygen and smaller amounts of other substancesmixtures can be either ( homogeneous or heterogeneous)plz check first good luck

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.
