Add up all the grams to get 9.96, then divide the amount if each element by the total;
4.56 of Pb divided by 9.96 = 0.4578313 now multiply by 100 and get 45.8% of Pb, then do the same for the rest of the elements, hope this helped <3
Answer:
No
Explanation:A single property is insufficient for identifying a substance
Answer: Everything can dissolve in water because water is considered a universal solvent
Explanation: Liquid water is cooler than solid salt and sugar, allowing them to dissolve easily.
This is a combustion reaction so there is a hydrocarbon + oxygen which always gives you carbon dioxide and water.
So: C4H10+O2-->CO2+H2O
The balanced equation would be:
2C4H10+13O2-->8CO2+10H2O <- so that's the molecular formula for butane.
Answer:
ionic.
Explanation:
the electronegativity difference is greater than 1.7.
