You are making a VERY large cookie. To help the cookie rise, you add baking soda. The baking soda will decompose to
produce carbon dioxide according to the following reaction:
2NaHCO3
Na2CO3 +H2O + CO2
You use 4.80 grams of baking soda (NaHCO3) in the recipe.
What volume of carbon dioxide (in Liters) will this amount of
baking soda produce? The temperature of the oven is 191°C
and you are at standard Wressure.

The sum of the oxidation numbers in a neutral compound is always

Afraction can be converted to a decimal by dividing the denominator into the numerator. use a calculator. divide to convert the fractions from part a to decimals. then describe the pattern you see in the decimal.

The chemical composition of soil varies with depth. an article in communications in soil science and plant analysis describes chemical analyses of soil taken from a farm in western australia. fifty specimens were each taken at depths 50 and 250 cm. at a depth of 50 cm, the average no3 concentration (in mg/l) was 88.5 with a standard deviation of 49.4. at a depth of 250 cm, the average concentration was 110.6 with a standard deviation of 51.5. find a 95% confidence interval for the difference in no3 concentrations at the two depths.
