To write the balanced chemical equation for the reaction of aluminium and sodium hydroxide and predict the volume of H 2 gas produced. Concept introduction: Aluminium belongs to group 3A of the periodic table. It react with a base like sodium hydroxide to produce sodium aluminate and hydrogen gas. There is evolution of heat and the reaction is highly exothermic. Hydrogen gas is released rapidly. Ideal gas equation is, P V = n R T Where P, V, T, n, and R are the pressure, volume, temperature and amount of substance respectively.

Question

The reaction of solid dimethylhydrazine, (CH3)2N2H2, and liquefied dinitrogen tetroxide, N2O4, has been investigated for use as rocket fuel. The reaction produces the gases carbon dioxide (CO2), nitrogen (N2), and water vapor (H2O), which are ejected in the exhaust gases. In a controlled experiment, solid dimethylhydrazine was reacted with excess dinitrogen tetroxide, and the gases were collected in a closed balloon until a pressure of 2.50 atm and a temperature of 400.0 K were reached.(a) What are the partial pressures of CO2, N2, and H2O?(b) When the CO2 is removed by chemical reaction, what are the partial pressures of the remaining gases?

One liter of chlorine gas at 1 atm and 298 K reacts completely with 1.00 L of nitrogen gas and 2.00 L of oxygen gas at the same temperature and pressure. A single gaseous product is formed, which fills a 2.00 L flask at 1.00 atm and 298 K. Use this information to determine the following characteristics of the product:(a) its empirical formula;(b) its molecular formula;(c) the most favorable Lewis formula based on formal charge arguments (the central atom is N);(d) the shape of the molecule.

How does the square root mean square velocity of gas molecules vary with temperature? Illustrate this relationship by plotting the square root mean square velocity of N2 molecules as a function of temperature from T=100 K to T=300 K.
