60g of solid Zn are added to 50mL of a 0.15M solution of HCl and undergo a chemical reaction according to the following equation: Zn(s) + 2 HCl(aq) ? ZnCl2(aq) + H2(g) a) How many grams of ZnCl2 can be produced from this reaction? b) How would you classify this reaction? As acid/base, oxidation/reduction or precipitation? c) Assuming that all the H2 that is produced in the reaction is taken to a different container, how much volume would it occupy under STP conditions? d) If the produced H2 is later mixed with 50g of F2 in balloon. What would be the partial pressure of F2 is the balloon is under 3atm of pressure? e) Pretend that the HCl of this reaction is used in the neutralization of 45mL of a solution of Ga(OH) 3. What was the molarity of the Ga(OH)3 solution?
Actually, whether these collisions are elastic or inelastic makes no difference as long as the walls are at the same temperature as the gas. Explain.
If the total pressure is 1.8 atm, what is the partial pressure of ethanol?
Iodobenzene ( C6 H5 I, bp 188 C) Steam distills at 98.2 C. How many molecules of water are required to carry over 1 molecule of iodobenzene. how many grams of water per gram of iodobenzene
The volume of each glass was 250mL. How much heat, in kJ, did the body have to supply to raise the temperature of the water to body temperature (37 C)?
If 30.0 grams of sulfuric acide react with 25.0 g of aluminum hydroxide, identify the limiting reactant.
Calculate the pH of this solution. When 0.20 mol of H+ ions is added to the solution what is the pH (assuming volume change is negligible)
Complete and balance the following redox equation that occurs in acidic solution using the set of smallest whole-number coefficients. What is the sum of all the coefficients in the equation
A compound X has molecular ion peaks in its mass spectrum at mass 140 and 142, and shows prominent peaks in its IR spectrum at 3150-3000 and 1600 cm^-1.
The reaction will be spontaneous at high temperatures because increasing the temperature of a system with a negative change in S eventually results in a positive change in G.
the oxidation of a trans-fat just skip the dehydrogenase reaction step and be catabolized the same as a saturated fatty acid?
The equivalence point is reached after addition of 25.0 ml Naoh a) calculate the ionication ka for the acid HA
