False. Because gas to a liquid is called condensation
Tree rings tell us how old the tree is.
<u>Answer:</u> D represents 222, E represents 86, F represents 234 and G represents 90.
<u>Explanation:</u>
The two given chemical reactions are a type of alpha decay processes. Alpha decay process is defined as the process, in which a heavier nuclei decays into lighter nuclei emitting alpha particle. The alpha particle released has a charge of +2 units. and is also known as a helium nucleus.
The isotope formed has atomic mass reduced by 4 units and atomic number reduced by 2 units.
So, for the chemical equations:
1.
D represents 222, E represents 86.
2.
F represents 234 and G represents 90.
Answer: g
Explanation:
0.92g/mL • 237mL/1cup - the mL cancel out leaving just grams
Answer:
349.5 moles
Explanation:
(I am assuming that there is a typo at the end, where Cuci solution = CuCl solution)
The formula for molarity is:
Molarity = moles in solution / volume of solution
Here, we are given both the Molarity and the volume. So we can plug it into the equation above and get:
2.33 = moles / 150
Now we solve for the moles by doing:
moles = 2.33 * 150
This gives us the answer of 349.5 moles.
