A general term for a chemical which accelerates a reaction without becoming chemically involved is called a ______.
AleksAgata [21]

Answer:

Catalyst

Explanation:

A general term for a chemical which accelerates a reaction without becoming chemically involved is called a catalyst.

Catalysts are used in industrial processes to speed up the rate of a chemical reaction. For instance, in the Contact process used in the production of sulphuric (vi) acid, vanadium(V) oxide (V2O5) is used as a catalyst to speed up the production of the acid. Vanadium(V) oxide (V2O5) is preferred to Platinum which was initially used as the catalyst since it does not react with any of the products of the process

A 0.1 mm sample of human blood has approximately 6000 red blood cells. An adult typically has 5.0 L of blood. How many red blood
olga55 [171]

 3.0 × 10¹¹ RBC's    (or)      3E11 RBC's


Solution:

Step 1: Convert mm³ into L;


As,


                                            1 mm³  =  1.0 × 10⁻⁶ Liters


So,


                                         0.1 mm³  =  X  Liters


Solving for X,


                       X  =  (0.1 mm³ × 1.0 × 10⁻⁶ Liters) ÷ 1 mm³


                       X  =  1.0 × 10⁻⁷ Liters


Step 2: Calculate No. of RBC's in 5 Liter Blood:


As given


                        1.0 × 10⁻⁷ Liters Blood contains  =  6000 RBC's


So,


                         5.0 Liters of Blood will contain  =  X  RBC's


Solving for X,


                      X  =  (5.0 Liters × 6000 RBC's) ÷ 1.0 × 10⁻⁷ Liters


                      X  =  3.0 × 10¹¹ RBC's


Or,


                     X  =  3E11 RBC's
