Answer:
Explanation:
We know we will need an equation with masses and molar masses, so let’s gather all the information in one place.
M_r: 58.12 44.01
2C₄H₁₀ + 13O₂ ⟶ 8CO₂ + 10H₂O
m/g: 9.511
1. Moles of C₄H₁₀
2. Moles of CO₂
The molar ratio is 8 mol CO₂:2 mol C₄H₁₀
3. Mass of CO₂
Since phosphoric acid is H3PO4, which is known from PO4, with a charge of 3- so 3 hydrogen would balance it out, and sodium hydroxide is NaOH, it can be assumed that it results in H3(OH)3 + Na3PO4.
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'.
Answer:
Explanation:
Power is defined as the rate at which energy is dissipated.
Its mathematical form is given by :
P = VI
Where
V is voltage and I is current
Using Ohm's law :
, R is resistance
Joule's law equation is given by :
Hence, the correct option is (d).
This is because it has a full outer valence shell! so there are 8 electrons and that means it doesn't have the urge the gain anymore
