Protons, the number of protons cannot change or the element will change as well.
Answer: The values for Ka and Kb for the species in solution must be known before a prediction can be made
Explanation:
1. If Ka is greater than Kb, the salt solution is acidic
2. If Ka is lesser than Kb, the salt solution is basic
3. If Ka is equal to Kb, the salt solution is acidic
The two chemical compounds are not the same, because their ratio is not equal. In both samples the composition of lead and oxygen is different.
<h3>
What is a chemical compound?</h3>
A chemical compound is a substance made of numerous similar molecules (or molecular entities) joined by chemical bonds and comprising atoms from various chemical elements. Therefore, a molecule made up of only one type of atom is not a compound. Chemical reactions, which may entail interactions with other molecules, can change a compound into a distinct substance. Atomic bonds may be broken or new ones created during this process.
<h3>
What are the calculations?</h3>
sample 1 = mass of lead / mass of oxygen = 12.92g/2g = 6.46 .
sample 2 = mass of lead/ mass of oxygen = 34.27 - 14.39/14.39 = 1.38 .
so, the ratios are not the same.
Hence, the two chemical compounds are not the same, because their ratio is not equal. In both samples the composition of lead and oxygen is different.
