I'm not sure on this I'm sorry I can't help you I wish I could!
A is true of UV rays.
B is true not of UV rays but rather of visible light.
C is true not of UV rays but rather of microwaves. (unless you actually toast your toast in a toaster like a normal person)
D is true not of UV rays but rather of radio waves.
He improved and followed from the works of Luigi Galvani, which used a 'frog galvanoscope' as a prototype of measuring current. He recognized that a compass could actually measure current, given that it is placed near coil of wire.
Answer: Carbon is stored in the lithosphere in both inorganic and organic forms. Inorganic deposits of carbon in the lithosphere include fossil fuels like coal, oil, and natural gas, oil shale, and carbonate based sedimentary deposits like limestone.
Explanation:
Answer:
Explanation:
First we find the Molecular weight of CaCl2
looking at the periodic table the MW of Ca is 40.078 and Cl is 35.453 and the ratio of ca to cl is 1:2 so we multiply cl by 2 which is 35.453*2=70.906
we add them together: 40.078 + 70.906 = 110.984 g/mol
now:
* 3.45 mol
the mol cancels out and we left with 3.45 * 110.984 grams = 382.89 grams
