Answer:
The correct answer is option 3. Run a test reaction of crude oil with ocean water over time with Oil Spill Eater present
Explanation:
In any laboratory experiment, all the apparatus needed to carry out a particular experiment must be provided. In this case, our apparatus will be crude oil with ocean water and oil spill eater which is the enzyme used.
We can then run a test reaction of crude oil with ocean water over time with Oil Spill Eater present.
Answer:
Molality = 0.43 m
Explanation:
Given data:
Mass of barium sulfide = 25.4 g
Mass of water = 349 g (349 g/1000 = 0.349 Kg)
Molality of water = ?
Solution:
Number of moles of barium sulfide:
Number of moles = mass/molar mass
Number of moles = 25.4 g/169.39 g/mol
Number of moles = 0.15 mol
Molality:
Molality = number of moles o f solute/ Kg of solvent
Molality = 0.15 mol / 0.349 Kg
Molality = 0.43 m
Cooking oil and the extinguishing agent combine to produce saponification, which creates a soapy foam blanket that separates fuel and oxygen.
<h3>What takes place when you add foam to a fire?</h3>
These are the ways foam functions: The foam smothers the flames by covering the fuel surface. The foam covering keeps the fuel surface and the flames/ignition source apart. Foam cools the fuel as well as any nearby metal surfaces.
<h3>What are some uses for a foam fire extinguisher?</h3>
The best and safest fire extinguisher to use on fires involving solid combustibles and flammable liquids (Class B) is foam (Class A). Typically, when liquids like gasoline, diesel, paint, oil, solvents, or spirits are burned, it can result in potentially deadly fires.
