What is moles of compound?</h3>
Avogadro's number (6.022 x 1023) of molecules (or formula units) make up one mole of a substance (ionic compound). The mass of 1 mole of a chemical is indicated by its molar mass. It provides you with the amount of grams per mole of a substance, to put it another way.
In essence, bond angles indicate that electrons dislike being close to one another. Negative ions are electrons. Negatives don't attract each other. Make a comparison now. A negative person is typically viewed as unpleasant or mean, and you don't want to interact with them.
The configuration or quantity of atoms are not mentioned in an empirical formula. It is typical for many macromolecules, such as silicon dioxide (SiO2), and ionic chemicals, such as calcium chloride (CaCl2).

Answer: C. The orbital speeds of planets closer to the Sun will be faster than planets farther away.
Explanation:
Centripetal force = gravitational force
Fg inversely proportional to distances (r)
because the value of the gravitational force is getting smaller as the distance is getting further from the sun, the orbital speed of the planet will be getting smaller
Remark
The balance numbers in front of Ag and AgNO3 are both 2. That number is in moles.
Rule: if the moles are the same in the equation, then whatever you are given for one, will be the same for the other. So you have 0.854 moles of Ag. You will also have 0.854 moles of AgNO3
Answer: 0.854 <<<<<
