State the Law of Conservation of Matter. How does the Law of Conservation of Matter figure into the simulation? Use how the masses of reactants and products were related after 10 g of calcium nitrate were added to 40 grams of sodium carbonate in the first example. Be specific and use actual values to make your point. Generalize this to all chemical reactions. Was the total mass of reactants always equal to the total mass of products or was the mass of the reactants that reacted equal to the total mass of products formed?
Why did adding more calcium nitrate produce more products to a point, then stop having an effect?
What is the limiting reactant before the stoichiometric amount of calcium nitrate was added? What is the limiting reactant after the stoichiometric amount of calcium nitrate was added? How can you tell from the simulation?
Approximately how many grams of calcium nitrate were required to react totally with 40.0 g of sodium carbonate? How many grams of product were formed at that point? Do your answers appear to obey the Law of Conservation of Matter?
Was it easy to tell when you added the stoichiometric amount of calcium nitrate?
What is the balanced equation? How did you determine it?
Carbonyl fluoride, , is an important intermediate used in the production of fluorine-containing compounds. For instance, it is used to make the refrigerant carbon tetrafluoride
Chemistry Concentrations, In each of the following pairs, indicate which has the higher concentration of Cl- ion
Suppose y was measured five times and average of these five measurements was 3.75. What is the uncertainty in x based on these five measurements?
If 3.0 Ml of distilled water is added to 2.0 ml of 0.35M CoCl2 solution, what is the concentration of the resulting solution.
f the water if brought to the vapour state at 204C and 710 KPa, where its enthalpy is 2649.4 KJ/Kg and its specific volume is 291.8 cm^3/g, what is the internal energy (U) at these conditions in KJ/Kg? c) Calculate the change in internal energy (d..
What mass of HClO4 should be present in 0.600 L of solution to obtain a solution with a pH of 2.50?
A balloon filled with helium gas has a volume of 741 mL at a pressure of 1 atm. The balloon is released and reaches an altitude of 6.5 km,where the pressure is 0.5 atm.
A spoon was silver plated electrolytically in a Silver nitrate solution. If 0.750 grams of silver was deposited on the spoon at a constant current of twenty mili amperes, determine how long in hours did the electrolysis take?
Next, you add 1.00 mL of 1.35 × 10-6 M lidocaine to this mixture Denoting lidocaine as L, calculate the fraction of lidocaine present in the form LH .MOPS Buffer Ka = 6.3 × 10-8. Lidocaine Kb = 8.7 × 10-7, calculate the fraction of lidocaine prese..
A proton in a linear accelerator has a de Broglie wavelength of 127 pm. what is the speed of the proton?
Provide me with your exact logic used to get the answer. A mysterious material was purified from safflower oil (hint: full of fatty acids). Upon ozonolysis it gave the following compounds in their respective molar ratios.
Chemical Kinetics - Show that only the reactants of the slow step of a reaction are found in the rate law of the reaction - which of the two steps is slower and which substance (if any) is probably an unstable intermediate?
