Well countries near the quitter of warmer than countries than the poles. So the mystery island would probably be near the equator near Florida or in Florida

• </span>Volume of the marshmallow:
V = 2.75 in^3 (but, 1 in^3 = 16.39 cm^3)
V = 2.75 × 16.39 cm^3
V = 2.75 × 16.39 cm^3
V = 45.0725 cm^3
• Density:
d = 0.242 g/cm^3
<span>• </span>Mass:
m = d × V
m = (0.242 g/cm^3) × (45.0725 cm^3)
m = (0.242 g/cm^3) × (45.0725 cm^3)
m = 10.907545 g
m ≈ 10.9 g <——<span>— this is the answer.
I hope this helps. =)

The answer is : Boiling water
Boiling water is a reversible change because you can take the water off the heat, and it will return to room temperature or it’s regular temperature.
Answer:
Rate of the reaction is 0.2593 M/s
-0.5186 M/s is the rate of the loss of ozone.
Explanation:
The rate of the reaction is defined as change in any one of the concentration of reactant or product per unit time.
Rate of formation of oxygen :
Rate of the reaction(R) =
Rate of formation of oxygen=3 × (R)
Rate of the reaction(R):
Rate of the reaction is 0.2593 M/s
Rate of disappearance of the ozone:
-0.5186 M/s is the rate of the loss of ozone.
mole fraction of potassium bromide = 0.23
Explanation:
We define mole fraction of a specific compound in a mixture as:
mole fraction of a compound = number of moles of the compound / total number of moles
in our case we have:
number of moles of potassium bromide = 3 moles
total number of moles = number of moles of potassium bromide + number of moles of water
total number of moles = 3 + 10 = 13 moles
mole fraction of potassium bromide = 3 / 13 = 0.23
