Anhydrous Copper sulfate is 39.81 percent copper and 60.19 percent sulfate by mass, and in its blue, hydrous form, it is 25.47% copper, 38.47% sulfate (12.82% sulfur) and 36.06% water by mass.
Answer:
123.5 kPa
Explanation:
P2=P1T2/T1
You can check this by knowing that P and T at constant V have a proportional relationship. Hence, this is correct.
It is simple, just set up a router and electrical box
"20 J" is the "Potential Energy" of "vase" on the table.
<u>Explanation</u>:
The body possess some energy according to the position of the object that is the when an object is placed at a height it stores some energy it is called "Potential Energy".
Formula used to calculate the "Potential Energy" is
Where, "m" is mass of vase is given that 2 kg, "g" is acceleration due to gravity is
and "h" is height of the object where it placed is 1 m.
Substitute the given values in the formula,
Potential energy of the vase =
Potential energy of the vase = 20 J
