Chemistry
1 answer:
d1i1m1o1n [39]3 years ago
8 0

Answer:

The symbol is the right answer.

Explanation:

The “ Symbol” is the correct answer because chemist uses the letters of the alphabet to denote the element. For instance, the element oxygen is denoted by the letter of the alphabet “O”, the hydrogen is denoted by the letter of alphabet “H”, Boron is denoted by the letter of alphabet “B”, etc. Here these are the examples that use one letter but there are other elements that use more than 1 letter as the symbol. For example, the Chlorine is represented by the Cl.

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

Please answer this percent yield question.
Sveta_85 [38]

Answer:

Percent yield = 82.5

Explanation:

Given data:

Actual yield of N₂ = 275 L

Theoretical yield = 333 L

Percent yield = ?

Solution:

Chemical equation:

4HCl + 6NO    →     5N₂ + 6H₂O

Percent yield:

Percent yield = actual yield / theoretical yield × 100

Percent yield = (275 L/ 333 L ) × 100

Percent yield = 0.825× 100

Percent yield = 82.5%
