A mixture of 0.500 mols of NO and 0.100 mols O2 are combined in a 5 L vessel. The two react according to the reaction: 2NO (g)⇋O2(g) + N2(g) (a) At equilibrium, [NO] = 0.0125M. What the concentrations of O2 and N2 at equilibrium? b. What is Kc of this reaction? c. Can you determine the value of Kp with this information? Explain please show steps and explain
In today's exp today's experiment you determine that you collected 1.33 X 10 mols of oxygen Calculate (show your setup for the conversion!) how many mols of H,O, were in your hydrogen peroxide solution. Note: te: Tou will need a conversion factor from the equation you balanced in question 2. mols of H,O2 Based on your answer above, how many grams of H.O, were in the hydrogen peroxide solution? (HO, has a molecular weight of 34.0 g/mol) grams of H,02...
Suppose 18.7 g of oxygen (O2) is heated at constant atmospheric pressure from 38.5°C to 123°C. (a) How many moles of oxygen are present? (Take the molar mass of oxygen to be 32.0 g/mol) (b) How much energy is transferred to the oxygen as heat? (The molecules rotate but do not oscillate.) (c) What fraction of the heat is used to raise the internal energy of the oxygen?
1) Given the reaction 2 H₂ + O2 = 2H2O. If you start with 3 mols of Oz, How many mols of water will be produced? 2) An elements atomic number is identical to the number of al protons & heutrons c) its mass b) protons + electrons electrons but not protons el electrons & neutrons.
13) Which statement is true about effective nuclear charge? A) effective nuclear charge increases as you move to the right across a row in the periodic table and increases as you move down a column. B) effective nuclear charge increases as you move to the right across a row in the periodic table and decreases as you move down a column. c) effective nuclear charge decreases as you move to the right across a row in the periodic table and...
