NaOH + H2SO4 →
_Na2SO4 +
_H2O
How many grams of Na2SO4 can be produced by the reaction of 250 moles of NaOH with sufficient H2SO4?

PLEAS HEL

Sorry i dont understand the question can you rephase it?

The answer is fossil fuels.

3-isopentane; 3-methylbutane, and 1,2-methylpropane do not meet iupac rules, so they are wrong names.the only valid name onthe list is 2-methylbutane, which is the same isopentane.this is its formula:                   ch2                    |ch3 - ch - ch2 - ch3answer: 2-methylbutane

So the main goal for the elements is stability which is a complete/full valence shell and typically the magic number for a stable element is 8 valence electron but not always. so elements to the left of the periodic table tend to be way less stable then those on the right, so the elements on the left are much more reactive.
