What’s the difference between polarity/ nonpolarity in bonds vs. polarity/ nonpolarity in molecules? How do you determine if a bond or molecule is polar or nonpolar?
Explain the difference between a stoichiometric reaction and a catalytic reaction, give one example for each that was not part of your experiments (be specific with a type of redox, combustion, or acid-base reaction). What is the oxidation state of the metals in this redox reaction (Before and After)? 2KMnO4+3H2O2->2MnO2+2H2O+3O2+2KOH What is a decomposition reaction? Name one that you have learned in 101L For the following reaction, which species is reduced HCl(aq)+Zn(s)->H2(g)+ZnCl2(aq)
Astronomy Mysteries Today 1.what’s dark matter? Why do astronomers believe it exists? 2. what’s dark matter? Why do astronomers believe it exists? 3. What’s a black hole? What’s the difference between stellar balck hoiles and galaxy black holes? Why is it black? 4. People ask “who” made the original mass that expanded in the Big Bang. What is one natural, as contrasted with supernatural, explanation for how the world began? 5. What may have been the first particles formed… before...

Is the number of atoms of each element conserved during a chemical example 2 Points] fuel, and natural gas?2 Pointsl combustion...
What’s the difference between a primary immune response and secondary immune response? Answer both in terms of the physiological responses and in terms of the mechanism by which it is achieved. Adaptive immunity is a response to a specific antigen. How does the adaptive immune system mount a specific response to an invading antigen? How is it possible to mount such a response to a wide array of antigens?
Please write clearly balanced equation and find the molar ratio 1.O2 + N2 =N2O 2.P+O2=P2O5 3.Hz+Al=AlH3 4.C+H2=C2H6 5.P+H2=PH3 write the balanced equation and Molar ratio 1. reaction between fluorine and zinc to form zinc fluoride 2. nitrogen and oxygen to form nitrogen dioxide 3. oxygen and sodium to form sodium oxide 4.boron and nitrogen form boron nitride 5.lithium and bromine to form lithium bromide
What is the difference between dietary fiber and functional fiber? (2 points) How do you calculate total fiber?
what’s the difference between a general goal and a specific goal? Can you still get to where you want to be if you don’t start out focused and motivated? Why or why not?
How do you determine the mole fraction of a monomer (f1) from the Molar Fraction Ratio (eg. I have the Molar Fraction Ratio of styrene: methylmethacrylate in a copolymer as 3.91 but do not know how to determine the monomer compositions of each of them so that I can then determine their reactivity ratios)?
(a) Write a stoichiometric table for the reaction N2 + 3 H2-> 2 NH3 for an isothermal, (b) If the entering total pressure is 16.4 atm and the entering temperature is 1727 oC (c) Plot the gas composition (molar fractions) as a function of the conversion. Is there isobaric flow system with equimolar (or equal molar) feeds of N2 & H2 calculate the concentration of hydrogen and nitrogen entering the reactor. anything worth noticing? Can you explain it? What are...
