How can I draw the Lewis structure for H2O? - Socratic
2014年7月15日 · You can find a procedure for drawing Lewis structures at this location. For H₂O, O must be the central atom The skeleton structure is H-O-H. O has 6 valence electrons, and each H has one. You must arrange 8 electrons in pairs so that O has 8 and each H has two electrons in its valence shell. The trial structure is You have eight valence electrons in your trial structure, …

The elementary reaction 2H2O(l) <--> 2H2(g) - Socratic
2018年1月28日 · Using the definition of the equilibrium constant, we find that K = 7.2 xx 10^-6 The equilibrium constant, K, for any reaction is defined as the concentrations of the products raised by their coefficients divided by the concentrations of the reactants raised by their coefficients. In this case, the concentrations are given as partial pressures. "In other words, the equilibrium …
Water can be formed according to the equation 2H2 + O2 2H2O
2018年5月29日 · 6 L In order to find the number of liters, we use the ideal gas law PV=nRT. Where: P = Pressure V = Volume n = Number of moles R = Gas constant (~~ 0.08206 L·atm·mol^-1·K^-1) T = Temperature (Kelvin) First, we find the number of moles of hydrogen by manipulating the equation to find the number of moles. n=(PV)/(RT) Then we plug in the …

2H2 + O2 → 2H2O What happens to the kinetic energy of
2018年4月6日 · The kinetic energy of molecules in a system can be graphed as a distribution. When heat is added to the system, more molecules have more energy, on average. This is why kinetics depends on temperature so heavily, and reactions generally proceed at faster rates at higher temperatures. More molecules are overcoming the activation energy E_"a" of the reaction.
Is 2Na+2H2O=2NaOH+H2 a redox reaction? - Socratic
2018年6月4日 · Yes, I hope. 2Na + 2H_2O ->2NaOH + H_2 Oxygen losing hydrogens so is being oxidised, The Na has gained oxygen so is reduced, you can also use oxidation numbers, elements have an oxidation state of 0 oxygen is almost always -2, and is in this case, H is almost always + 1 and is in this case, Na: Goes from 0 to +1 as -2 from oxygen + 1 from hydrogen, …
