Sodium. Oxygen is electronegative and hece pulls bonding electron towards oxygen atom, creating a partial negative charge on the oxygen atom. As unlike charges attract, it is then attracted to the positively charged sodium ion.
Answer:
4Fe+ 3O2 → 2Fe2O
Explanation:
Let's return to the chemical reaction in which iron (Fe) combines with oxygen (O2) to form rust, or iron oxide (Fe2O3). The equation for this reaction is: 4Fe+ 3O2 → 2Fe2O
Answer:
6.48L
Explanation:
Given parameters:
V₁ = 2.5L
P₁ = 105 kPa
P₂ = 40.5 kPa
Condition: constant temperature
Unknown:
V₂ = ?
Solution:
To solve this problem, we are considering pressure and volume relationship. This should be solved by applying the knowledge of Boyle's law.
The law states that "The volume of fixed mass of a gas varies inversely as the pressure changes if the temperature is constant".
Mathematically;
P₁V₁ = P₂V₂
where P and V are pressure and volume, 1 and 2 represents initial and final states.
Substitute to find the V₂;
105 x 2.5 = 40.5 x V₂
Solving for V₂ gives 6.48L
Answer:
Explanation:
CH₄ + H₂O(g) ⇒ CO(g)+3H2(g)
Equilibrium constant
K₁ = [CO][H₂]³ / [CH₄][H₂O]
CO(g)+H₂O(g) ⇒ CO₂(g) + H₂(g)
Equilibrium constant
K₂ = [CO₂][H₂] / [CO][H₂O]
CH₄(g)+2H₂O(g) ⇒ CO₂(g)+4H₂(g)
Equilibrium constant
K = [CO₂][H₂]⁴ /[CH₄][H₂O]²
= [CO][H₂]³ / [CH₄][H₂O] X [CO₂][H₂] / [CO][H₂O]
K₁ x K₂
K = K₁ x K₂
