Answer:
4 moles of H3PO4
Explanation:
Molar mass of P4O10 = 284 g/mol
Number of moles of P4O10 reacted = 284g/284 g/mol = 1 mole of P4O10
From the reeaction equation;
1 mole of P4O10 yields 4 moles of H3PO4
Hence, 284 g of P4O10 yields 4 moles of H3PO4
The charge of the ion is +1
Bromine. both Bromine and Mercury are both a liquid at STP. :)
To identify why a metal measurement was different in the experiments look for the variable that was different in the experiment and analyze how this change affected the results.
<h3>What is an experiment?</h3>
An experiment is a procedure that aims at probing or discovering something. For example, you can test if a plant grows faster/slower by using an experiment.
<h3>What causes different results in similar experiments?</h3>
The most common cause for this situation is that one of the factors or variables is slightly different. For example, if I add 50mL of water to a plant rather than 20mL of water every day this might cause different results.
Based on this, if the metal content was different you should analyze if any of the factors changed in this experiment and find out how this change affected the general results.
Note: This question is incomplete because there is limited information about the experiment; due to this, I answered it based on general knowledge.
