It affects our everday life because of new inventions and easier ways to make/produce different stuff!
Answer:
Explanation:
the nymph looks like a smaller version of the adult insect, & it also has no wings & molts.
Find volume of pillow
L=78cm
B=55cm
H=25cm
Now
Mass=5.5kg
Density of water=1000kg/m^3
As it is less than density of water it will float on water
Answer is: variables that were manipulated during the experiment.
The two main variables in an experiment are the independent and dependent variable.
Dependent variable is the variable being tested and measured in a scientific experiment.
Dependent variables depend on the values of independent variables. The dependent variables represent the output or outcome whose variation is being studied.
Laboratory room number is the least important.
Explanation:
It is given that volume is 0.50 L and molarity is 0.485 M. Hence, number of millimoles will be calculated as follows.
Number of millimoles = Molarity × Volume
As there are 1000 mL in 1 L. So, 0.50 L equals 500 mL.
Therefore, putting the given values into the above formula as follows.
Number of millimoles = Molarity × Volume
= 0.485 M × 500 mL
= 242.5
Thus, we can conclude that 242.5 millimoles of copper(II) sulfate has been added by the chemist to the flask.
