A certain hybrid car has a mileage rating of 53 miles per gallon. If the car makes a trip of 295 miles, how many gallons of gasoline will be used?

Classify each of these reactions. Reaction 2 NaOH(aq) + Pb(CIO3)₂(aq) - C₂H₂(g) + 30₂(g) - 2 AgNO3(aq) + Zn(s) HI(aq) + LiOH(aq) 2 NaC1O3(aq) + Pb(OH)₂ (s) 2 CO₂(g) + 2 H₂O(1) Zn(NO3)₂(aq) + 2 Ag(s) H₂O(1) + Lil(aq) redox Answer Bank acid-base neutralization Type precipitation

Convert the following pH or pOH values to [H*] or [OH] concentration Example: pH = 7.0, [H*] = 1.0 x 10-7 M pH = 5.3, [H*] = РОН 3 11.1, [Н']]- РОН 3 6.6, [ОН]- pH = 2.5, [OH]] = In two or three sentences, compare and contrast the Bronsted-Lowry definition of acids/bases and the Arrhenius definition. What are the similarities and differences? Complete the acid-base equation, providing the missing species. Under each species, write A, B, CA, or CB for acid, base, conjugate acid, or conjugate base, respectively. H2O + HCO3 + H3O*

Please help me solve this question, i have trouble figuring it out, explain and make sure its 1000% correct thank you sm

Consider each chemical equation and select all that represent a chemical reaction.     2NaI(aq)  +  Pb(NO3)2(aq)  →  2NaNO3(aq)  +  PbI2(s)     2KBr(aq) + MgCl2(aq) → 2KCl(aq) + MgBr2(aq)     HCl(aq) + NaOH(aq) → NaCl(aq) + H2O(l)

Match each pollutant with their final product in our atmosphere. > SO₂ NO₂ CO CH4 1. CO2 2. H₂SO4 3. HNO3

In one experiment, 0.150 L of SnCl4 (d = 2.226 g/mL) was treated with 0.323 L of triethylaluminum (Al(C2H5)3); d = 0.835 g/mL).What is the theoretical yield in this experiment (mass of tetraethylstannane, Sn(C2H5)4)?

A student conducts an experiment of the combustion of ethane in the presence of oxygen. The graph below represents data collected in the lab. COMBUSTION OF ETHANE +ethane +02 - H20 120 100 80 60 40 20 10 15 20 -20 TIME Which line on the graph above would represent the limiting reactant and which line on the graph above would represent the excess reactant for the combustion of ethane? In your answer, cite specific evidence from the graph to support your determination. NUMBER OF MOLES

7) The most important reaction that allows our cars to do work is octane (CSH18) combustion 2 C8HI8 + 25 02 à 16 C02 + 18 H20 a) Theoretically speaking, if we fully combust 3.0 kg of octane, and keep the products at STR, what volume of gas do we expect to be produced? b) If the % yield for this combustion reaction is 90%, what is the actual volume? 8) Name two characteristics that describe real gases and not ideal gasses. 9) a) A climber takes a mole of ideal qgas to the top of Mount Everest, where the pressure is 304 torr and the temperature is subzero at -17° C. What is the volume of the gas? b) The gas taken to Mount Everest is oxugen gas. What is the root mean square velocity of gas molecules in that sample of gas? 10.) a) An 8.00L tank at 7.3° C is filled with 24 g of dinitrogen monoxide (N2O) and 8.2 g of sulfur hexafluoride gas (SF6). What is the mole fraction of sulfur hexafluoride? b) What is the ratio between the rates of effusion of sulfur hexafluoride and dinitrogen…

I have 3.025 lb H2SO4 and 200 gal of water.  How many molecules of sulfuric acid do I have?  What is the pH? All hydrogen atoms convert to hydronium ions. 1 oz= 28.35 g 1 gall=3.785 L
