Hi there!

The <span>major accomplishment of the Apollo missions was to successfully land Americans on the Moon and to return them safely to Earth. One major reason for this was to establish a way for us to travel to other celestial bodies safely so we could research them and study how they work or to see if they are inhabitable.

2. How many moles of fluorine are required to produce 12.0 grams of
LuckyWell [14K]

Answer:

0.0984mol of F2

Explanation:

The equation for the reaction is given below:

Kr + F2 → KrF2

Let us convert 12g of KrF2 to mole. This is illustrated below

Molar Mass of KrF2 = 84 + (2x19) = 84 + 38 = 122g/mol

Mass of KrF2 = 12g

Number of mole = Mass /Molar Mass

Number of mole of KrF2 = 12/122 = 0.0984mol

From the equation,

1mole of F2 produced 1mole of KrF2.

Therefore 0.0984mol of F2 will produce 0.0984mol of KrF2

Directions: Read the paragraph and identify the correct words that fit in the given sentences
TiliK225 [7]

Answer:

1. Elements

2. one

3. properties

4. Chemical

5. metal

6. non-metal

7. metalloids

8. Compounds

9. one

10. more

11. components

12. chemical process

Explanation:

In the given paragraph a brief about the difference between element and compound is given.

Elements are made up of the same type of atoms and each element is made up of one atom, that is they cannot be broken down into any other substance. Each element is different from each other due to its properties, though some have the same physical properties but are different in chemical properties.  Elements can be classified as metals such as iron and silver, non-metals such as oxygen and hydrogen, and metalloids such as boron and silicon.

Compounds are a combination of one or more elements such as water and salt. Compounds can be easily broken down into components through a chemical process.

Hence, the correct answer is:

1. Elements

2. one

3. properties

4. Chemical

5. metal

6. non-metal

7. metalloids

8. Compounds

9. one

10. more

11. components

12. chemical process
