Answer:
197 + (35.5×3) = 303.5
Explanation:
relative formula mass is the sum of the relative atomic masses of the atoms in the formula ( AuCl3 )
Answer:Well, if you mean atoms, it has 2 Hydrogen atoms and 1 Oxygen.
Explanation:Water is H20 therefore, it has 2 Hydrogen atoms and 1 Oxygen. Water isn't made up of particles, they are made of atoms.
Answer:
1) 1.808 *10^8 vacancies per cm^3
2) 101,64ºC
Explanation:
You can use the following equation relating the number of vacancies with the energy required to produce them and the temperature:
Where N is the number atoms per unit of volume, you can calculate this number with the density of copper:
And you can substitute all values in the equation:
Now you solve for temperature and and use n as 1000 times the value of before:
Answer:
A chemical equation is the symbolic representation of a chemical reaction.
