It's urgent How would you find the number of 'chalk molecules' it takes to write your name on the board What would i need to do?
To find the number of chalk molecules it takes to write your name on the board, first measure the length of your name in centimeters. Next, estimate the thickness of the chalk line you would draw, then calculate the volume of chalk used by multiplying the length by the thickness. Finally, divide this volume by the volume of a single chalk molecule to determine the total number of molecules needed. You may need to use the density of chalk and the molecular weight to find the volume of one molecule.
What else can I help you with?

How many moles in a teaspoon of chalk?
The molecular weight(M) of chalk(CaCO3) = (40+12+48)g/mol =100g/mol and teaspoon (m)= 4.93g We know, n=m/M So, n= (4.93/100) mol = .0493 mol To find out number of molecules we use, N= n x NA equation. N= .0493 mol x 6.02 x 1023 molecules/mol =2.968 x 1022 molecules Therefore, there are 2.968 x 1022 molecules in a teaspoon of chalk.

Is chalk board eraser conductor or insulator?
It would be an insulator- chalk board erasers normally consist of two parts, a wooden handle and a soft pad that wipes off the chalk from the board. Neither of these parts are conductors of electricity.
Why does surface of a reactant influence the rate of the reaction?
A chemical reaction is nothing but the conversion of the reactant molecules into product molecules. By increasing the surface area of the reactants more number of reactant molecules are exposed which eventually increases the rate of the reaction...for example, powdered chalk piece dissolves faster in water than a piece of chalk.
