Since the number of atoms in a substance is so large , a unit to count them was created. This unit is the number of atoms in 12
larisa86 [58]

The number of atoms in one mole of any substance is measured by Avogadro's number. The value of Avogadro's number is 6.023 x 10 ^23. It is named after scientist Avogadro who proposed this number. 12 grams of carbon-12 represents 1 mole of carbon-12. For this reason, the number of atoms present in 1 mole of any substance is 6.023 x 10 ^23. Therefore, the number of atoms present in 1 mole carbon-12 is 6.023 x 10^23.


(Answer) This unit is the number of atoms in 12 grams of carbon-12 and known as Avogadro's number.

b. increase in surface area

<h3>Further explanation</h3>

Given

Speeding up a chemical reaction

Required

Factors used to speed up reactions

Solution

There are several factors that influence reaction kinetics :  

1. Concentration  

2. Surface area  

3. Temperature  

4. Catalyst  

5. Pressure  

6. Stirring  

Temperature is related to the kinetic energy of the particles. Heat is absorbed causes the particles of matter to move faster so that the reaction can take place faster

The enlarged surface area of the reactants causes more particles to react with other particles.

50 g square block of sulfur can be broken into small pieces or powdered so that more particles come into contact with each other
