<span>The answer is A. In chemistry, Gibbs Free Energy is defined as the enthalpy of the system minus the product of the temperature times the entropy of the system. To write it as a formula, G = H - TS, delta G=delta H-T*delta S, where delta denotes the change.</span>
The number that would be in the place of x and Y is
x=2
Y=1
Hence the formula will be K2Se
Explanation
When K+ which is positively charged combine with selenide (se2-) which is negatively charged they form an ionic bond K2Se.
- 2 potassium ions K+) loses 1 electron each while selenide ion (Se2-) accept the 2 electron, Hence the formula of ionic bond is K2Se
The field of philosophy (not including science) that deals with things other than matter and energy would be <span>metaphysics.
</span>
There are 2 kinds of metaphysics, general and special.
I will first explain the general metaphysics.
General metaphysics: The study of ultimate realty <span>as in the big picture of reality and is done empirically by most contemporary philosophers. Items of study in general metaphysics are categories, universals, attributes etc.
</span>
Special metaphysics: <span>Special metaphysics has potentially an infinite number of sub branches, each </span>studying one<span> particular subject. </span>One<span> such subject may be ghosts and spirits but most contemporary philosophers don't take this particular subject matter seriously. </span>
X * 0.10 mg/mL = 0.50 mg
x = 0.50 mg / 0.10
x = 5.0 mL
hope this helps!
