Cc stands for cm cubed (cubic centimetre).
So
6cc=6 cm^3.
Answer:
True
Explanation:
They are built from particles and blobs of congealed lava ejected from a single vent. As the gas-charged lava is blown violently into the air, it breaks into small fragments that solidify and fall as cinders around the vent to form a circular or oval cone, making them the simplest out there
Answer:
A. When an anhydrous salt becomes hydrated, it can change color.
Explanation:
The cobalt (II) chloride (CoCl₂) have a blue color in the anhydrous form while after hydration, most commonly it will form the hexahydrate, it will change its color to violet.
B. not really, if we take the cobalt (II) chloride in the anhydrous form the bond between cobalt and the chloride it is ionic.
C. nope, the mass is changed depending on the lost water mass
D. no, the mass will increase and sometimes as in the case of cobalt (II) chloride the color will change, so you have changes of the physical properties of the substance.
I think it's the minimum required energy to the reaction to occur
