Doing this so i can get points but the answer is spectrophotometry
Answer: An insulator would be made out of material unable to conduct electricity due to lack of fluid movement for electrons, such as rubber. Rubber properties not only prevents them from freely moving, but also helps electrons stay tightly bound to each other.
Hope this helps ^_^
C because D stands for delta therefore it signifies change
Answer:
1.6 ×10⁻¹ kj
Explanation:
Given data:
Mass of chloroethane = 0.38 g
Heat absorbed = ?
Solution:
Molar mass of chloroethane = 64.51 g/mol
Molar heat of vaporization = 26.4 kj/mol
Number of moles:
Number of moles = mass/ molar mass
Number of moles = 0.38 g/ 64.51 g/mol
Number of moles = 0.006 mol
Heat absorbed:
0.006 mol × 26.4 kj/mol
0.16 kj
or 1.6 ×10⁻¹ kj
the solute is the one that dissolves meaning its particles are separating into the solvent, and the solvent is the one that dissolves the other substance.
