calculate how much energy is release when 755 grams of copper cools from 125.0C to 19.0C

A 3.0 g sample of an alloy containing lead and tin is dissolved in nitric acid. An excess of
sulfuric acid is then added to the mixture, resulting in the formation of 2.37 g of a precipitate.
Identify the precipitate which is being formed.

What is the molarity of acetic acid in vinegar?
If volume of vinegar sample is 5.00ml, molarity of NaOH is .25M, initial reading is .25ml and final reading is 17.50ml

How many grams of aluminum dichromate are formed from the double displacement reaction between 107.5g of aluminum nitrate and excess sodium dichromate? The products are aluminum dichromate and sodium nitrate (show work)

When heated, KClO3 decomposes into KCl and O2.

2KClO3= 2KCl + 3O2
If this reaction produced 17.2 g of KCl, how many grams of O2 were produced?

How many moles of nitrogen dioxide, NO2, are needed to react with 2.83 moles of water, H2O?



4 NO2(g) + 6 H2O(g) → 7 O2(g) + 4 NH3(g)

what dissolves most rapidly in 100 mL water

If 32.3 grams of CH4 is burned in excess oxygen, how many grams of carbon dioxide is produced?

For the reaction Q → W + X, the following data were obtained at 30°C. [Q] is M, Rate is in M/s
[Q]: 0.170 0.212. 0.357
Rate: 6.68 x 10^-3 1.04 x 10^-2. 2.94 x 10^-2
Determine the rate constant of this reaction and state its units?

Antimony pentachloride, SbCl5, decomposes according to the following equation:
←
SbCl5(g) → SbCl3(g) +Cl(g)

An equilibrium mixture in a 5.00 L flask at 448 °C contains [SbCl5] = 0.002575 M, [SbCl3] = 0.008014 M and [Cl2] = 0.008011 M

1.State the type of equilibrium in the reaction

2.Calculate the mass in grams of each species that will be found when the mixture is transferred into a 2.00 L flask at the same temperature.
