- If the abundance of the first isotope is 68.037%, then the abundance of the second isotope is 100%-68.037%.
Substituting into the atomic mass formula,

Adenosine triphosphate is the correct answer
No, because HPO₄ is a multi-atom ion and has its own name which is Hydrogen phosphate.
Answer:
The answer to your question is: Q = 3153600 Joules
Explanation:
Data
Q = ?
m = 48 kg
T1 = 21°C
T2 = 94°C
Cp = 900 J/g°C
Formula
Q = mCpΔT
Q = (48)(900)(94 - 21) = 3153600 Joules
It's 3. There are two Cl in the reactants and 3 in the products, and they need to be balanced/equal. Only way to do that is add three on the left side, which will give you 6 Cl (3×2Cl) and then 2 on the other side, which will also give you 6 Cl (2×3Cl)
