<span>~He was working without prior knowledge toward creating a periodic table of elements that had been done in Europe in the 1860s

~ scandal when he got married to his second wife before he divorced his first wife

~he was working with data that was not very precise (technology didn't exist at the time to make accurate measurements (e.g., weights) for the things he was working on.) Many elements had also not been discovered yet, so he had to guess at a lot of things when making his conclusions. </span>

Answer:

Answered

Explanation:

1. He married his second wife before giving divorce to his first wife. This made him an outsider in the scientific community making it difficult for him to raise funds for the research.

2. Back then there were no precise measuring instruments, so it was difficult for him to measure correct data. Many of the elements were yet to be discovered, so he guessed and by fortune most of his guesses were right.

3.The elements that were not discovered at that time, he left blank spaces for them.

Explanation:

To find the amount of product that would be formed from two or more reactants, we need to follow the following steps;

  • Find the number of moles of the given reactants.
  • Then proceed to determine the limiting reactant. The limiting reactant is the one in short supply which determines the extent of the reaction.
  • Use the number of moles of the limiting reactant to find the number of moles of the product.
  • Then use this number of moles to find the mass of the product

Useful expression:

    Mass   =  number of moles x molar mass
