because the substance in the potassium permanganate crystals are permeable to water, so that means it will dissolve instantly while poured into water

Answer:

Explanation:Potassium permanganate is used as an oxidizing agent in water treatment to remove colour,taste and make some viruses and bacteria inactive.

When you put potassium permanganate in a beaker and add water,its particles randomly. You will observe a purple slowly spreading at the base of the water. The purple solution will slowly spread into the rest of the water until a uniform colouration is form. This process is diffusion.

Which organisms develop gills from pharyngeal arches and later develop lungs to breathe on land

lawyer [7]

Apart from cutaneous respiration present in all species, most lissamphibians are born in an aquatic larval stage with gills. After metamorphosis, they develop lungs to breathe on land. The larvae of urodeles and apods present external, filamentous and highly branched gills which allow them to breathe underwater.

57. Estimate Potential Energy A boulder with a

Oksanka [162]

Answer: 4.9 x 10^6 joules

Explanation:

Given that:

mass of boulder (m) = 2,500 kg

Height of ledge above canyon floor (h) = 200 m

Gravita-tional potential energy of the boulder (GPE) = ?

Since potential energy is the energy possessed by a body at rest, and it depends on the mass of the object (m), gravitational acceleration (g), and height (h).

GPE = mgh

GPE = 2500kg x 9.8m/s2 x 200m

GPE = 4900000J

Place result in standard form

GPE = 4.9 x 10^6J

Thus, the gravita-tional potential energy of the boulder-Earth system relative to the canyon floor is 4.9 x 10^6 joules
