What are the abiotic factors a polar bear needs to survive in the tundra?

1 answer:

7 0

abiotic factors that affect polar bears are the cold, snow and water. The extreme cold in the Arctic region that the polar bear inhabits means that it has adapted in several ways. The polar bears have grown long, thick fur and have a thick layer of blubber just under the skin. They also have small ears and tails, which reduces the loss of cold through these areas.

Q#1 Give a combination of four quantum numbers that could be assigned to an electron occupying a 5p orbital.

Gnesinka [82]

Answer:

For an electron in 5p orbital

5,1,-1,+1/2

For an electron in 6d orbital

6,2,-2,+1/2

Explanation:

The term quantum numbers refers to a set of values that can be used to determine the region in space where it is likely to find an electron. This region in space where there is a high probability of finding an electron is known as an atomic orbital. An atomic orbital is actually a wave function according to the Schrödinger wave equation.

There are four quantum numbers used in describing an atomic orbital: the principal quantum number (n), the orbital angular momentum quantum number also called azimuthal or subsidiary quantum number (l), the magnetic quantum number (ml), and the electron spin quantum number (ms).

For a 5p orbital;

n= 5, l= 1, ml= -1,0,1 ms= +1/2 or -1/2

For 6d orbital;

n= 6, l= 2, ml= -2,-1,0,1,2, ms= +1/2 or -1/2

Since we are requested to use a four quantum number description that can be assigned to an electron in these levels;

For an electron in 5p orbital

5,1,-1,+1/2

For an electron in 6d orbital

6,2,-2,+1/2

38.5 mol of P4O10 contains how many moles of P?

stellarik [79]

The subscripts tell the ratio of one element to another in a compound. In this case, there are 4 P atoms per 10 O atoms. This could also be interpreted as 4 mol P per 10 mol O. Therefore:

Mol P = (38.5 mol P4O10)/(4 mol P/ 1 mol P4O10) = 154 mol P

Degger [83]

The correct answer is the second option. <span>Baking soda fizzing in vinegar is an example of a chemical change. This example is a chemical reaction which undergoes a chemical change since new substances are being formed the fizzing of the system represent that gas is being produced by the reaction.</span>
