The principal quantum number of the first d shell is three. The principal quantum number determines the size of the orbital. The secondary divides the shell into subshells called orbitals and designated by the letters s, p, d, f. From the sequence of the electron configuration, it can be seen that at a principal quantum number of three the d shell first appear.
Answer:
80ml
Explanation:
you have your initial concentration to be 0.25 mole on your final volume to be 250 ml and your final concentration to be 0.8 0.08 molar you don't have your initial volume sotify your initial volume you use the expression see 1 * 21 equals see two times between you make when when the subject then 1 equals to 2 x 2/3 one you know substitute your values into it to get being one that's your original volume to be at the latest or 80 ml
Answer: Balance, multiply, find ratio
Explanation:
Balance the equation to be able to multiply correctly and accurately, multiply, and this will give you the molar ratio
Decomposition.
Decomposition is the chemical reaction in which a compound breaks down into the two elements or molecules that formed the compound. In this case, Dialuminium Trioxide has broken down into the basic components of Al2 and O2.
