Use the reaction below to solve the following problem: Calculate the mass in grams of oxygen required to fully react with 8.00 moles of iron metal. 4 Fe + 3 02 --> 2 Fe2O3 **Be sure to use the correct number of significant digits!

The density of water is 1 g/cm cubed and in order for the pebble to sink its density has to be greater than the density of water and in order for the twig to float its density has to be less than the density of water

Ineed with this also i hope you understand it

Answerd. may include all of these are many definitions of bases: the  brønsted-lowry definition of acids and bases says that bases are proton acceptors.the arrhenius definition of acids and bases says that bases increase [oh⁻] in solution (thereby producing oh⁻ ions)the lewis definition of acids and bases says that bases donate electron pairs.therefore, the sensible answer is that a base may include all of the described characteristics.
