<span>Answer
is: activation energy of this reaction is 212,01975 kJ/mol.
Arrhenius equation: ln(k</span>₁/k₂) = Ea/R (1/T₂ - 1/T₁<span>).
k</span>₁<span> = 0,000643
1/s.
k</span>₂ = 0,00828
1/s.
T₁ = 622 K.
T₂ = 666 K.
R = 8,3145 J/Kmol.
1/T₁<span> = 1/622 K = 0,0016 1/K.
1/T</span>₂<span> = 1/666 K =
0,0015 1/K.
ln(0,000643/0,00828) = Ea/8,3145 J/Kmol · (-0,0001 1/K).
-2,55 = Ea/8,3145 J/Kmol · (-0,0001 1/K).
Ea = 212019,75 J/mol = 212,01975 kJ/mol.</span>
Answer:
A neutron is a subatomic particle with a mass comparable to a proton and a neutral electrical charge. A neutron is a subatomic particle with a mass of 1 and charge of 0. ... While the number of protons in a atom determines its element, the number of neutrons determines its isotope

Answer:
Explanation:
A) Reactant that can produce more of the product
Excess reactant:
In a given reaction, the reactant that is in excess supply is the excess reactant. If the amount of the excess reactant is match, more of the product will be produced.
B) Reactant that can produce a lesser amount of the product
Limiting reactant
The limiting reactant restricts the progress of the reaction. It determines the amount of product that can be formed.
C) Amount of product predicted to be produced by the given reactants
Theoretical yield
For a given amount of reactants, the theoretical yield determines the amount of products that can be produced.
Step 1: write the equation:
P₄(s) + 6F₂(g) → 4PF₃(g)
Step 2: Molar mass of P₄ = 30.97 g/mol × 4 = 123.88 g/mol
Step 3: Number of moles of phosphorus
n = m/M
n = 8.5 g/123.88g/mol
n = 0.07 moles
Step 4: 0.07 × 12 = 0.84 moles of fluorine.
Fluorine is diatomic gas so we multiplied the number of moles by 12.
Step 5: To find the mass of fluorine we multiply the number of moles with the molar mass.
Mass of fluorine = 0.84 × 228
= 191.52 grams.
It goes Meter mega meter giga meter and kilometer
