The compound H2O can be decomposed to form H2 and O2. This can be represented at the atomic level by a chemical equation: 2H2O 2H2 + O2 According to the law of conservation of mass, if 26.8 grams of H2O decomposes and 3.0 grams of H2 is formed, how many grams of O2 must simultaneously be formed? _____grams O2
Ammonium nitrite, NH4NO2, decomposes upon heating to form N2 gas according to the following balanced chemical equation. When a sample of NH4NO2 was decomposed in a test tube, 813.9 mL of N2 gas was collected over water at 47.64 °C and the total pressure was 765.9 torr. NH4NO2(s) → N2(g) + 2 H2O(l). How many grams of N2 were collected?
The Dumas method can be used to determine the amount of nitrogen in an organic compound. This method involves passing the compound over hot, solid CuO, where it decomposes to give N2, CO2 and H2O (g). The gaseous products are passed through a concentrated KOH solution to remove the CO2 and then through H2O. After the passage through H2O the gas contains only N2 saturated with water vapor. When a 0.253-g sample of a certain compound is treated in this way...
Under certain conditions, the substance ammonium nitrate can be broken down to form dinitrogen monoxide and water. If 32.8 grams of ammonium nitrate react to form 18.0 grams of dinitrogen monoxide, how many grams of water must simultaneously be formed?
D Question 2 1 pts Calcium carbonate, CaCO3, decomposes upon heating to form CO2 gas according to the following balanced chemical equation. When a sample of CaCO3 was decomposed in a test tube, 650 mL of CO2 gas was collected over water at 32.0 °C and the total pressure was 795 torr. The vapor pressure of water at 32.0°C is 36 torr and 1 atm = 760 torr. CaCO3(s) CaO(s) + CO2(g) How many grams of CO2 were collected?
Under certain conditions, the substance ammonium nitrate can be broken down to form dinitrogen monoxide and water. If 28.2 grams of ammonium nitrate react to form 15.5 grams of dinitrogen monoxide, how many grams of water must simultaneously be formed? -------------grams water
As early as 400 B.C., Greek philosophers proposed that matter was made up of particles. During the 1800s, John Dalton linked the idea of atoms with the chemical identity of an element. His atomic theory of matter involved the following postulates. 1. Each element is composed of extremely small particles called atoms. 2. All atoms of a given element are identical to one another in mass and other properties, but the atoms of one element are different from the atoms...
