Colour arises due to partially filled d-orbitals. D-orbitals are split into two sub-orbitals with slightly different energies. When an electron in the lower energy d sub-orbital absorbs light, it moves up...
Options:A: 50cm^3, 54 degrees celsius, 1.0x10^5 Pa B: 50cm^3, 327 degrees celsius, 1.0x10^5 PaC: 100cm^3, 54 degrees celsius, 2.0x10^5 PaD: 100cm^3, 327 degrees celsius, 2.0x10^5 PaThe equation to u...
Increasing the temperature of an endothermic reaction would favour the forward reaction, thereby increasing the concentration of the products compared to reactants, which in hand increases the value of Kc...
First, we have to convert the starting measurements for the HCl and CaCO3 content into moles so we can compare the ratios to the formula. 40cm^3=0.04dm^30.04dm^32.5mol.dm^-3=0.1 moles of HClmass/molar...
When considering the optimal reaction conditions, one must check for pressure, temperature, concentration and catalysts involved. Le Chatelier's principle states that if a change to the system is made, th...
