Answer:
The pOH of a solution that has a pH of 6.25 at 100°C is 7.75 (option D)
Explanation:
pOH + pH = 14
pOH = 14 - 6.25
pOH = 7.75
Therefore, at 100°C, the Kw of water is 5.6x10⁻¹³ and the pOH of a solution that has a pH of 6.25 at 100°C is 7.75.
Thus, option D, is the correct answer.
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:
Explanation:
Hello,
In this case, since the molarity is defined as the ratio of the moles of the solute to the volume of the solution in liters:
For the given volume and molarity, we solve for the moles of ammonium sulfate (solute) as shown below:
Best regards.
One of the atoms involved must be a metal and the other a nonmetal
Multiply the weight of the object by the distance it traveled to find the amount of work output. For the example: 10 lbs. x 1 foot = 10 foot-pounds. Find the work efficiency by dividing the work output by the work input and multiplying by 100.
