3 NO2(g) + H2O(g) 2 HNO3(g) + NO(g) At constant temperature and pressure, what is the maximum volume, in liters, of HNO3(g) that can be made from 10.39 L of NO2(g) and 15.53 L of H2O(g)? That is the entire question and this is AP Chem but gas stoichiomatry from regular chem. I...

Pb(NO3)2+HCl-->PbCl2+HNO3 Pb(NO3)2+2HCl-->PbCl2+HNO3 I'm not sure. Long ones are a bit more difficult.

NH3 + H^(from HNO3) ==> NH4^+ The equation you want is the above one. How it works is below. pH = pKa + log (NH4^+)/(NH3) So when HNO3 is added to the solution, the NH3 reacts with it to form NH4^+, it increases NH4^+ and decreases NH3

Classify the following as: Weak or strong acid, weak or strong base, salt (from weak/strong acid and base). If appropriate, split the formula into its component ions. HNO3 So far, all I have is: HNO3 + H2O -> NO3^- + H3O^+ And I know HNO3 is a strong acid. What would I ...

chemistry
Absolutely yes. HI is a strong acid, ionizing 100%, the same for HNO3, and KOH is a strong base and it ionizes 100%. Furthermore, the pOH of KOH will be the same as the pH of HNO3/HI.

Chemistry
1. Make an electroplating cell but make the key the positive electrode. Cu ==> Cu^2+ + 2e 2. Use dilute HNO3 to dissolve the Cu. Some attention must be devoted to this; if the concn of HNO3 is too large the key can be corroded (attacked) also.

Nitric acid,HNO3, is available ata a concentration of 16 M. how much would react with 5.58 g of KOH acording to the following equation? HNO3+KOH-H2O+KNO3 dont understand? does not give me a volume amount to work with and I really dont understand how to solve it

2HNO3 + Ba(OH)2 ==> 2H2O + Ba(NO3)2 moles HNO3 = M x L = ?? moles Ba(OH)2 = M x L = ?? Convert moles HNO3 and Ba(OH)2 to moles of the product and the SMALLER answer is the one to choose. The reactant left over is what determines the final pH.

First you write the equation, then balance it. Ba(OH)2(aq) + 2HNO3(aq) ==> Ba(NO3)2)aq) + 2H2O(l) Next you use the coefficients in the balanced equation (that's why you write and balance the equation FIRST) to convert mols HNO3 to mols Ba(OH)2. 2.5 mol HNO3 x [1 mol...

Let's see now. According to the equation, 3 mols Cu use 8 mol HNO3, so 6 mols Cu will use ?? mols HNO3.

Write and balance the equation. Calculate moles HNO3. moles = M x L. Convert moles HNO3 to moles Ba(OH)2 using the coefficients in the balanced equation. Finally, use M = moles/L to calculate molarity.

Here is a worked example of a simple stoichiometry problem. I work these limiting reagent problems (you know it is limiting reagent when BOTH reactants are given) by solving TWO of the simple ones. http://www.jiskha.com/science/chemistry/stoichiometry.html So convert L NO2 (...
