Answer:
62.06 g/mol
Explanation:
We are given that a solution containing 10 g of an unknown liquid and 90 g
Given mass of solute =
=10 g
Given mass of solvent=
=90 g
Freezing point of solution =-3.33
C
Freezing point of solvent =
C
Change in freezing point =Depression in freezing point
=Freezing point of solvent - freezing point of solution=0+3.33=
Hence, molar mass of unknown liquid is 62.06g/mol.
Answer:
If all the heat energy contained in a body is removed and changes in its temperature is described below in detail.
Explanation:
It moves from a body at a greater temperature to a body at a cheaper temperature. All element survives as solids, liquids, or gases. The material can transfer from one station to another if warmed or cooled. When heat is provided to a body its heat increases: When a physical body, hard, liquid. When heat is provided is stopped to a body its temperature decline.
B and D
Because these two points are below equator on sun is shining directly above equator which is experiencing summer
The complete question is as follows:
A cow is given a growth hormone and then compared to another cow that was not given a growth hormone. Both cows were weighed at 2 years. What is the independent variable?
if the cow is given growth hormone or not
weight of the cow
same cows
type of growth hormone
Answer:
The correct answer is - if the cow is given growth hormone or no
Explanation:
The independent variable is here is if the growth hormone is given or not as the variable which is subject to change or manipulated during an investigation and affects the dependent variable is known as the independent variable.
Due to this independent variable manipulation the weight of the cows might be different which makes the weights as the dependent variable.
