What is the ΞHΒ° for the following reaction (in kJ/mol)? 2 Na <sub>(s) </sub>+ 2 H<sub>2</sub>O<sub> (l)</sub> β<sub> </sub> 2 NaOH<sub> (aq) </sub>+ H<sub>2</sub> <sub>(g)</sub>
From the given info, we know the amount of heat released when 2 moles of Na is reacted.Β We're asked for the heat per 0.5 moles.Β So, (368.6 kJ/2mol)0.5000 mol = 92.15...

2 Fe<sup>+2</sup>(aq) + H<sub>2</sub>O<sub>2</sub>(aq) ---> 2Fe<sup>+3</sup>(aq) + 2 OH<sup>-1</sup>(aq) What is the oxidation state of oxygen in H<sub>2</sub>O<sub>2</sub>
Oxidation state of oxygen in H2O2.Since hydrogen has an oxidation state of +1Then we'll be having;(1)2+O2=02 + O2 = OThen bringing the constant to the right side have;O2 = -2...

Can you please help me balance this equation?Na[sub]3[/sub]PO[sub]4[/sub] + Ba(NO[sub]3[/sub])[sub]2[/sub] = Ba[sub]3[/sub](PO[sub]4[/sub])[sub]2[/sub] + NaNO[sub]3[/sub]
The correct balanced equation is: Na3PO4 + Ba(NO3)2 = BaPO4 + Na3(NO3)2
