Answer:
B
Explanation:
Compounds are made up of 2 or more different atoms that bond to form a compound.
this is beta decay as the mass number stays the same but proton number changes, this is specifically beta minus as a neuron changes into a proton
0.78 is what the verified answer says
Answer:
I think it's replacement because the B and D just swap places in the end equation
Use the formula:
P1V1/T1N1 = P2V2/T2N2
You can cross out T1,N1,T2, and N2 because you are working with pressure and volume in this equation.
Now, you are left with Boyle’s Law:
P1V1 = P2V2
Substitute the values in
STP = 1 atm for pressure
(1 atm)(2.1L) = P2 (0.125 L) [I converted 125 ml to liters so they would be the same unit]
Now, divide both sides by 0.125 to find P2
P2 = (1 atm)(2.1 L)/(0.125 L)
Liters cancel out
P2 = 16.8 atm
