Mr. Forester and Mr. Chavarin were cooking burgers at the Senior Picnic (this was pre-pandemic) and the propane grill ran out of

fuel. When they went to change tanks they noticed that the "empty" tank was covered in ice, which seemed unusual for a sunny June day in Oceanside. Sure enough, the outside temperature was 25 degrees Celsius, while they tank was at -5. If the empty tank still had 0.75 mol of propane once it reached equilibrium (gauge reading 0 kPa) with the air (the barometer said 101.27 kPa that day) and the initial reading for the pressure gauge on the fuel cylinder was [400 + the last three digits of your ID] kPa, how many moles of propane had they burned so far?
I don't know what this is asking me to do so if somebody can help me that'd be great.

You made hypochlorous acid (HOCI) by mixing bleach (NaOCI) with:
Annette [7]

<u>Answer:</u> When bleach is mixed with water, it produces hypochlorous acid.

<u>Explanation:</u>

The chemical name for bleach is sodium hypochlorite. When this compound is reacted with water, it produces hypochlorous acid and sodium hydroxide.

The chemical equation for the reaction of sodium hypochlorite and water follows:

NaOCl+H_2O\rightarrow HOCl+NaOH

By Stoichiometry of the reaction:

1 mole of sodium hypochlorite reacts with 1 mole of water to produce 1 mole of hypochlorous acid and 1 mole of sodium hydroxide.

Hence, when bleach is mixed with water, it produces hypochlorous acid.

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
