The molar mass for PCL3 is 137.33 g/mol
Mercury-199 is composed of 80 protons, 119 neutrons, and 80 electrons.
A chain reaction is a nuclear reaction that occurs when sufficient unstable nuclei are present so that when one splits (decays), its products hit other unstable nuclei, causing them to decay and initiating a chain reaction.
If this reaction goes uncontrolled, a massive explosion occurs. Such a reaction is the type that went uncontrolled when nuclear bombs were dropped over Hiroshima and Nagasaki in World War II. A chain reaction is much like dominoes all in a row; when one goes down, they all go down in order. The only way to block the chain reaction is to pull out a domino or to block the fall so the "chain" is broken.
The amount of fissionable material needed to accomplish a spontaneous chain reaction is called the critical mass. The critical mass for U-235 is about 1 kg. This explosive fission process takes place quickly, and an incredible amount of energy is released when it occurs.
So it would be C.
Answer:
37.1mL
Explanation:
This is a simple dilution problem where you utilize the equation:
(C=Concentration, V=Volume)
C1V1=C2V2
10.6(y)=0.715x0.550 (Y is unknown because we are trying to find how much of the original solution we need to dilute to make the final solution)
The solve for y and you get
y= 0.0317 L but this is in L and we want mL so multiply by 1000 you get
y= 37.1mL
When heating up, the balloon slowly rises and flies up in the air again. Explanation: The volume of the balloon decreases by the low temperature, because the gas inside is cooled down. When heated up, the pressure in the balloon rises, the balloon expands, and will reach to its original shape.
