Beta decay which is also sometimes referred to as beta emission is a phenomenon in which a certain element releases an electron. For this case, each carbon has an atomic number of 6, leaving us with 8 neutrons, now, the mass number will be retained and the atomic number will be decreased by one. Thus, the answer is Boron-14.
Answer:
a. 0.14042
b. 0.221
c. equal to a.
5) 0.579 L
3) 8.1e6 ms
Explanation:
Hello,
In the attached photo you'll find the numerical procedure to get the results.
Best regards.
One mole of Na2SO4 is 6.022 * 10^(23) molecules. We can divide this into the quantity in the question to find a value of 1.5/6.022 = 0.2491 moles. Rounded to two significant figures and put in scientific notation, we can rewrite this quantity as 2.5 * 10^(-1) moles
Answer:
Explanation:
A) Formal charges represent an actual separation of charges.(FALSE)
(B) ΔHo rxn can be estimated from the bond enthalpies of reactants and products.(TRUE)
C)All second-period elements obey the octet rule in their compounds(FALSE).
(D)The resonance structures of a molecule can be separated from one another in the laboratory.(FALSE)
Bond enthalpy which is also reffered to as bond energy is the amount of energy that is required to break one mole of a bond.
taking the single bond between Oxygen and Hydrogen into considerationthe bond energy between their single bond is 463 kJ/mol.
formal charge is used for the comparison of the number of electrons present around an atom in a particular molecule with the number of electrons present around a neutral
Your answer is
Ca(OH)₂ + 2HNO₃ → Ca(NO₃)₂ + 2H₂O I hope it is at least :P
