<span>Most metals are solid at room temperature with the exception of mercury, which is liquid at room temp. but, most metals turn liquid when the temperature is hot. Like, Gallium is liquid on hot days, but they harden after a while when it's cold.

The 14.8-g bleach sample contained 0.113 moles of H₂O₂.
X X = 0.113 moles of
This is an example of the oxidation-reduction chemical reaction, which moves electrons from one species to another. The oxidation states of our species were thus altered as a result of the transfer of electrons. As we are concentrating on it in this case, the hydrogen peroxide we have weighs 14.8 g and was measured with accuracy. 0.113 moles are in question.
<h3>What is titration used for and what does it entail?</h3>
A titration can be used to figure out the concentration of an unknown solution by comparing it to one with a known concentration. Until the reaction is finished, the titrant (the known solution) is typically added from a buret to a known volume of the analyte (the unknown solution).

Oil spills happen when people make mistakes or are careless and cause an oil tanker (a ship that carries oil from one country or place to another) to leak oil into the ocean. ... Natural disasters (like hurricanes) may cause an oil spill, too, by flipping an oil tanker over, causing oil to come pouring out.
An oil spill is the release of a liquid petroleum hydrocarbon into the environment, especially the marine ecosystem, due to human activity, and is a form of pollution. The term is usually given to marine oil spills, where oil is released into the ocean or coastal waters, but spills may also occur on land.

Molar mass of O2= 16.0 g/mol
molar mass of H2O= 18.0 g/mol
10.0 g of O2= 5 mol
80.0 g of H20= 5 mol
you need twice as the moles of H2 as O2 so there is insufficient H2 and it is the limiting reactant and all of it will react therefore 5.00 moles of H2 with 2.5 mole of O2 to produce 5.00 moles H2O
5.00 moles of H2O is 5.00x18.00=90.00 g
so the answer is 90.00
