Answer:

1.) Eyewash station --> D

2.) Absorbent material --> G

3.) Fire extinguisher --> F

4.) Safety Shower --> E

5.) Biohazard container --> J

6.) Broken glass container --> I

7.) Safety goggles --> C

8.) Lab apron --> H

9.) asbestos gloves --> A

10.) Latex gloves --> B

Explanation:

In an equipped laboratory, alot of safety equipments are made available and kept in area that it could be easily accessed in the laboratory. Safety or protective equipments are those materials that helps protect a laboratory personnel while at work on the lab.

These equipments include:

--> Eyewash station: This is an equipment used in the laboratory during emergency to rinse chemical from the eye. Therefore option D is correct.

--> Absorbent material: They are used to contain small spills in the laboratory. Therefore option G is correct.

--> Fire extinguisher: This equipment is used to put out small fires. Therefore F is correct.

--> Safety Shower: This is used to rinse away chemical from clothes and on skin during emergency. Therefore option E is correct.

--> Biohazard container: This container is used to safely dispose bacteria culture, blood and other living tissues. Therefore option J is correct.

--> Broken glass container: This is used to dispose cracked, chipped or broken bottle in the laboratory. Therefore option I is correct.

--> Safety goggles: This helps to protect the eye from chemical and broken glasses. Therefore option C is correct.

--> Lab apron: This is worn by the laboratory personnel to help protect the skin from chemical and biohazards. Therefore option H is correct.

--> Asbestos gloves: these are heat resistant gloves used to protect the hands from heat. Therefore option A is correct.

--> Latex gloves: these are equally worn by the laboratory personnel to protect the hands from chemicals and biohazards

What is the molar mass of F^2​
amm1812

F2 means that there are two flourine's usually a gas is a diatomic molecule.

Since a fluorine molecule has an atomic mass of 18.998 that molar mass of F2 would be 18.9998 *2 = 37.996 except in molar mass the units change so instead of being g/mol it would just be grams.

so 37.996 grams

hope this helps!

Write net ionic equations for the reactions that take place when aqueous solutions of the following substances are mixed: a. sod
strojnjashka [21]

Answer:

A. H₃O⁺ + CN⁻ → H₂O + HCN

B. OH⁻ + NH₄⁺ → NH₃ + H₂O

C. CN⁻ + NH₄⁺ → HCN + NH₃

D. HSO₄⁻ + CH₃COO⁻ → SO₄²⁻ + CH₃COOH

E. ClO⁻ + NH₃ → NO REACTION

Explanation:

Part A.

Sodium cyanide consist of Na⁺ and CN⁻ ions. CN⁻ is a conjugate base and accept H⁺ ion from nitric acid to form HCN (hydrogen cyanide).

Part B.

Ammonium chloride consist of NH₄⁺ and Cl⁻ ions. Sodium hydroxide is a strong base dissociate completely in solution convert into ammonium hydroxide and sodium chloride.

Part C.

Sodium cyanide consist of counter ion Na⁺ . CN⁻ combined with ammonium bromide to form ammonium cyanide and sodium bromide.

Part D.

Potassium hydrohen sulphate consist of potassium counter and hydrogen sulphate ion. Hydrogen sulphate combined with acetate ion to form acetic acid and sulphate ion.

Part E.

There have no reaction because hypochlorite and ammonia both are bases.

How many electrons do atoms like to have in their outer shell?
irakobra [83]

Explanation:

In general, atoms are most stable, least reactive, when their outermost electron shell is full. Most of the elements important in biology need eight electrons in their outermost shell in order to be stable, and this rule of thumb is known as the octet rule.
