Ineed , the longer i look at this question the more i confuse ! consider the unbalanced equation: hc2h3o2 (aq) +ba(oh)2 (aq) --> h2o (l) +ba(c2h3o2)2 (aq) balance the equation and determine how many moles of ba(oh)2 are required to completely neutralize 0.461 mole of hc2h3o2.

How many atoms are there in 5.70 mol of mg

Use this information to determine the number of calends electrons in the atoms. which of the following correctly compares the stability of the two atoms? a) both are unreactive b) both are highly reactive c) a is unreactive and d is reactive d) a is reactive and d is unreactive

A5.000 g sample of niso4 h2o decomposed to give 2.755 g of anhydrous niso4. what is the formula of the hydrate? what is the full chemical name for the hydrate? what is the molar mass of the hydrate? niso4•_h2o what is the mass % of water in the hydrate?
