Answer:
d. magnesium sulfide, mgs
Explanation:
Ionic bonds or also called eletrovalent bond is one of the chemical bonds that forms between the atoms of molecules or compounds. It is the kind of bond that forms between a positively charged atom and a negatively charged atom. The positive atom transfers electrons to the negative atom.
In this question, Magnesium Sulfide, MgS is a compound whose atoms are held together by ionic bonds. The magnesium ion (cation) transfers its two valence electrons to the sulfur ion (anion) to form the stable MgS.
Answer:
water was added to powdered rock
Explanation:
Answer:
The correct option is a.
Explanation:
125 kPa
125kpa - 2x 4x x
Total pressure after reaction = 176 kPa
125 kPa - 2x + 4x + x = 176 kPa
x = 17
125 kpa - 2x = 125 kPa - 2(17) = 91 kPa
Initial pressure of the dinitrogen pentoxide ,(at t=0) =
Final pressure of the dinitrogen pentoxide, (at t = t) = P = 91 kPa
The rate constant is = 
It will take 113 minutes for the total pressure to reach 176 kPa.
