Answer:
the law of conversation of mass States that mass is an isolated system is neither created or destroyed by chemical reactions or physical transformations. according to the law of conversation of mass the mass of the product in a chemical reaction must equal to the mass of reactants
hope It helped you
Answer:The ones "most" similar would be the ones closest in mass as well. Those would be Lithium (Li) and Potassium (K)
Explanation:
You would also need to know the mol of sodium. After knowing the mol, write down the reaction;
Na + H20 -> NaOH + H2
Use the mol ratio, to find the amount of mol of sodium hydroxide. (Remember to balance the equation first)
After you have the necessary variables, use the following formula:
mass of sodium hydroxide = mol of sodium hydroxide x molar mass (relative/formula mass of sodium hydroxide)
That is how you will find the mass of sodium hydroxide.
Answer:
The piece of wood will sink
Explanation:
If an object has a density higher than water, it will sink, and the piece of wood is more dense than water when measured.
