Answer:
Reactants: Ethanol (C₅H₅OH), Oxygen (O₂)

Products: Carbon dioxide (CO₂) and Water (H₂O)

Explanation:
Let’s rewrite each part of the described situation in chemical equation terms.

Ethanol - C₂H₅OH
is burned in the prescence of - +
oxygen - O₂
producing - →
carbon dioxide - CO₂
and - +
water - H₂O

Chemical equation:
C₂H₅OH + O₂ → CO₂ + H₂O

The terms on the left side of a chemical equation are reactants, and the terms on the right side of a chemical equation are products.

Therefore, since we know this, ethanol (C₂H₅OH) & oxygen (O₂) are the reactants, and carbon dioxide (CO₂) & water (H₂O) are the products.

28 grams of Al react with 30 Oxygen gas (O2) to produce Al Oxide (Al2O3). How many grams of Al Oxide will be produced
Kamila [148]

Answer:

58

Explanation:

Due to conservation of energy, the sum of the reactants = the sum of the products. So 28 + 30 = 58g

Calculate the rate constant at 200.°C for a reaction that has a rate constant of 8.30 × 10−4 s−1 at 90.°C and an activation ener
Sergeu [11.5K]

Answer:

23.0 s⁻¹ is rate constant

Explanation:

Using the Arrhenius equation:

k = A * e^(-Ea/RT)

Where k is rate constant

A is frequency factor (1.5x10¹¹s⁻¹)

Ea is activation energy = 55800J/mol

R is gas constant (8.314J/molK)

And T is absolute temperature (24°C + 273 = 297K)

Replacing:

k = 1.5x10¹¹s⁻¹ * e^(-55800J/mol/8.314J/molK*297K)

k = 1.5x10¹¹s⁻¹ * 1.53x10⁻¹⁰

k = 23.0 s⁻¹ is rate constant    i hope this helpsss
