Suppose that a newly discovered element called centium has 3 isotopes that occure in nature. These are centium -200, centium -20
vodomira [7]

Answer:

The answer to your question is 203.8 g

Explanation:

Data

Average atomic mass = ?

Centium-200

Centium-203

Centium-209

Equal amounts

Process

1.- Determine the abundance of each isotope.

If they are in equal amounts in nature, just divide 100 by 3

             100/3 = 33.33 % or 0.333

2.- Determine the Average atomic mass

Average atomic mass = Atomic mass 1 x abundance + Atomic mass 2 x

                                        abundance + Atomic mass 3 x abundance

- Substitution

Average atomic mass = 200 x 0.333 + 203 x 0.333 + 209 x 0.333

- Simplification

Average atomic mass = 66.6 + 67.6 + 69.6

Result

Average atomic mass = 203.8 g

[06.01]The same amount of heat is removed from 2 kg of water and from 1 kg of water starting at the same temperature. What will
liq [111]
<span>Answer: The 1 kg of water will reach the lowest temperature
</span>
Both of the objects is water so their specific heat should be same. The heat removed from the 2kg of water which is 2 times of mass than the 1kg water. Since the heat removed, both of their temperatures will drops. But 2kg water temperature drops will be half of 1kg water.

Plz help me with these 4 questions!! Need right correct answers!! Thxx!!
lubasha [3.4K]

number one: when substances like rock and minerals are being physically broken down, its called weathering.

Number two: when particles are carried away to another location exp " a river carrying rocks to an ocean" that's called deposition

Number three: this would also be weathering because it is physically being worn down

Number four: would be a topographic map, because theses maps use lines to study elevation instead of color
