Answer:
A
Explanation:
Developing work ethics won't lower your stress although it may make your conscience a little happier. Not B
Not C. Procrastinating just makes things harder. The mountain of things to do is not diminishing at all and your stress knows it.
Not D. Although D is the second best answer, setting goals is not really an action. It is a plan for how to work. But it is not work. Still having a goal is useful.
The answer is A. Just keep hitting what you have to do at a steady pace.

Answer:
These three numbers, n, ℓ, and s can be used to describe an electron in a stable atom.
Explanation:
Each electron's quantum numbers are unique and cannot be shared by another electron in that atom. This property is called the Pauli Exclusion Principle.

Answer:
Ti6Al4V1 or Ti6Al4V
Explanation:
So, from the question above we are given the following Important data or parameters or information which is going to help us in solving this question and they are;
The "surgical-grade" titanium is made up of 64.3% titanium, 24.19% aluminum and 11.42% vanadium.
This is a stoichiometry Question so in order to be able to solve this question one must have the basic knowledge of stoichiometry, it is advisable that one revise it.
So, let us delve right into the solution of this question. Recall that, the formula for Calculating the number of moles = mass/molar mass.
Hence, the number of moles of titanium,Ti = 64.3/47.87 = 3 moles.
Also, the number of moles of aluminum = 24.19/26.98 = 0.8966
For vanadium; 11.42/51 = 0.22
The next step is to divide each number of moles component by the lowest number of mole, that is;
Ti = 1.34/ 0.22 = 6; Al = 0.8966/0.22= 4 and V = 0.22/0.22 = 1.
Thus, the emperical formula is = Ti6Al4V.
