Valerie wants to examine the properties of a thick liquid but is finding it difficult to pour the liquid into a beaker. she needs to finish her investigation before the end of class. which method will allow her to pour the liquid easily? boiling the liquid vigorously applying heat to the liquid placing the liquid in the refrigerator mixing the liquid with another solution

Answer : Option B) Applying heat to the liquid.

Explanation : Valerie can heat the liquid as by heating the liquid the viscosity of the fluid will change and will be lower than before. This will allow her to pour the liquid into another beaker and study its properties. Increasing the heat of the liquid will try to increase the intermolecular distance between the molecules o the fluid which will allow it to flow easily.

B) applying heat to liquid

Explanation:

just took it on edge. Hope this helps!

percent abundance for cu-63 can be shown as:

63 x + 65 (1-x) = 62.9296

65 - 62.9296 = 2 x

x = 1.035

thus, percent abundance for cu-63 is 1.035

percent abundance for cu-65 can be shown as:

63 x + 65 (1-x) = 64.9278

65 - 64.9278 = 2 x

x = 0.0361

thus, percent abundance for cu-63 is 0.0361

the mass spectrum of cu-63 showing the intense peak as, this isotope is found in nature more abundantly around 92.38 % in comparison to cu-65 which is found 62.58 % naturally
