What volume of N2, measured at 24 °C and 719 mm Hg, will be produced by the decomposition of 14.5 g NaN3? 2 NaN3(s)     2 Na(s) + 3 N2(g)

What volume (L) of 0.550 M hydrochloric acid solution can be prepared from the HCl produced by the reaction of 15.0 g of NaCl with excess sulfuric acid, assuming a reaction yield of 91.2%? NaCl(s) + H,SO,1) → HCl(g) + NaHSO,(s)

How do you write a net ionic equation for the formation of gas  ex Al2(SO4)3(NH4)2SO4 •24 H2O + NaOH --> ?

What volume of hydrogen (STP) is producedby dissolving 1.1 moles of aluminum in sulfuric acid?2 Al(s) + 3 H2SO4 → Al2(SO4)3 + 3 H2

In Module #4, we discussed the role of chlorofluorocarbons (CFCs) in catalyzing the destruction of O3 in the stratosphere. One example of a CFC that is known to exasperate formation of the hole in the O3 layer is dichlorodifluoromethane (CF2Cl2). In the year 2000, this chemical reached its peak concentration of 2.2 x 10-11 M in the atmosphere. The destruction of CF2Cl2 can be approximated as a first-order process and the 1996 treaty on CFC emissions has eliminated its release into the atmosphere. Given that the rate constant for destruction of CF2Cl2 in the atmosphere is 0.009 yr-1, how long will it take for the concentration of CF2Cl2 to decline to 0.22 x 10-11 M?

Calculate the number of moles of H2O that will be produced by the reaction of 1.46 mole of solid Mg(OH)2 with excess aqueous HCl.
