Answer:
A meniscus forms when placed in glass
Explanation:
Water has a high boiling point, is a polar molecule and has surface tension which eliminates the other options.
Answer:
The second choice and the fourth choice are both based on science fact. The others are examples of pseudoscience.
Answer:
Mass percentage of glucose : 22.3%
Mass percentage of sucrose:77.7%
Explanation:
Mass of glucose in sample =
Mass of sucrose in sample = y
Mass of sample = 1.10 g
x + y = 1.10 g ..[1]
Osmotic pressure of the solution =
Volume of the solution = 25.0 mL = 0.025L ( 1 mL = 0.001 L)
Temperature of the solution =T = 298 K
..[2]
Solving [1] and [2] we get :
x = 0.2453 g
y = 0.8547 g
Mass percentage of glucose :
Mass percentage of sucrose:
The moon would stop orbiting us and instead it’s kinetic energy would keep it going in one direction indefinitely until it collides with another entity. There is a specific name for this phenomena but I cannot recall it.
