20 B203(s) + 12180 HF(l) = 4060 BF3(g) + 609 H20(l)
This is held together by the charges of anions and cations that are attracted to each other, which is the reason why crystal lattice is being formed beside the fct that it has tightly packed network. The crystal lattice are the crystals which has an arrangement that could be describe with its three dimensional feature.
There are 30 inches in 2.5 just know that a foot is 12 inches so 12 times 2.5 is 30
Given:
2 Mg + O2 → 2 MgO
So,
<span>(25.0 g of Mg / 24.3051 g/mole) x (1/2) x (22.4 L/mole) = 11.5 L of Oxygen will react with 25 grams of magnesium metal.</span>
For the reaction;
N2(g) + O2(g) = 2NO(g)
Kp = pNO²/ pN₂pO₂; (No units)
where;
pNO is the partial pressure of NO;
pN₂ is the partial pressure of nitrogen
pO₂ is the partial pressure of Oxygen
The equilibrium constant Kp is deduced from the balanced chemical equation for a reversible reaction, NOT experimental data as is the case for rate expressions in kinetics.
Kp changes with temperature considerably changing the position of an equilibrium, and, at a constant temperature, and therefore constant K, the position of an equilibrium can change significantly depending on relative concentrations/pressures of 'reactants' and 'products'.
