Triangle UVW is the pre-image of triangle RST with a scale factor of 3. Find the area of triangle UVW if the area of triangle RST is 9 cm2.
Given the unbalanced equation: (NH4)2 CO3-> NH3 + CO2 + H2O Calculate the mass of ammonia gas that is produced if 1.25g of ammonium carbonate decomposes completely.
Calculate how many grams of the product(s) would be produced by complete reaction of 0.125 mole of the first reactant. CaCO3 + 2HCl --> CaCl2 + CO2 + H2O
Calculate how many moles of products(s) would be produced if 0.500 mole of the first reactant were to react completely. BaCl2 + 2AgNO3 --> 2AgCl +Ba(NO3)2
Balance the equation. Cu + HNO3 --> Cu(NO3)2 + NO2 + H2O I'm having a little trouble getting this equation to balance. Thank you in advance! :)
I got 10.4g as well. My teacher must have put down the incorrect answer... thank you for your help!
A limiting reactants problem. 6.32g of sodium sulfate is reacted with 12.03g of barium nitrate. How many grams of the precipitate would you expect to collect. The answer my teacher gave me is 16.0g BaSO4, but I cannot get it. The equation I formed is: Na2SO4 + Ba(NO3)2 --> ...
how much NaOH would be needed to dissolve in H2Oto prepare 2.00L of a NaOH solution in which [OH-]=0.95 M?
What is the density of CO2 at STP in g/L? How would I do this problem using dimensional analysis?
Why are the results of an independent samples test different from the results of a Tukey HSD test on the same data?
