Answer:

A deer

Explanation:

Volcanic Ash and dust would cover the surface of the pond. This would prevent the growth of planktons which serves as food for them. Sunlight would not be able to penetrate the pond to furnish it with a very important ingredient for photosynthesis. As we know that most fishes are heterotrophs.

For grasses and trees, the dust and Ash particles would cover the leaves which is the site of photosynthesis. Plants are autotrophs that manufactures their own food through sunlight and carbondioxie. Most of the plants would die off since they can't remove the Ash and dust covering on them.

A deer is an heterotroph and a motile animal. It can easily leave that region and source for food elsewhere in the ecosystem.

How many moles are in 25.2g of KMnO4?
Zolol [24]
When finding the moles in a compound you have to know the grams. In this case, 25.2 grams are given for KMnO4. To find the moles you would divide the amount of grams by the molar mass of KMnO4. The molar mass of KmnO4 is 158.034. You you would now divide 25.2 by 158.034 which is 0.15946 moles. Depending on how many decimal places the questions asks for is dependent on you. I just went with 5 significant figures.

3. What is the atomic mass of phosphorous if phosphorous-29 has a percent abundance of 35.5%, phosphorous-30 has a percent abund
daser333 [38]

Answer:

The atomic mass of phosphorus is 29.864 amu.

Explanation:

Given data:

Atomic mass of phosphorus = ?

Percent abundance of P-29 = 35.5%

percent abundance of P-30 = 42.6%

Percent abundance of P-31 = 21.9%

Solution:

Average atomic mass = (abundance of 1st isotope × its atomic mass) +(abundance of 2nd isotope × its atomic mass) + (abundance of 3rd isotope × its atomic mass  / 100

Average atomic mass  = (29×35.5)+(30×42.6) + (31×21.9) /100

Average atomic mass =  1029.5 + 1278 + 678.9/ 100

Average atomic mass  = 2986.4 / 100

Average atomic mass = 29.864 amu.

The atomic mass of phosphorus is 29.864 amu.

MEASUREMENT AND MATTER Interconverting temperatures in Celsius and Kelvins The metal osmium becomes superconducting at temperatu
nexus9112 [7]

Answer: -272^0C.

Explanation:

Temperature of the gas is defined as the degree of hotness or coldness of a body. It is expressed in units like ^0C and K  

These units of temperature are inter convertible.

We are given:

Temperature of the gas = 655mK=0.655K    (1mK=0.001 K)

Converting this unit of temperature into ^0C by using conversion factor:

(t-273.15)^0C=tK

273.15K=0^0C

Thus 0.655K=(0.655-273.15)^0C=-272^0C

Thus the temperature is -272^0C.
