Density of a liquid determines how it will layer (heaviest to lightest). If the liquid is least dense it will float to the bottom. Layers will remain separated because each liquid is actually floating on top of the more dense liquid beneath it.
Al 3+ ions to S 2- ions in a neutral compound is 12 oxygen
The correct answer for the question that is being presented above is this one: "D. 15 millimeters." An object 5 millimeters high is located 15 millimeters in front of a plane mirror. T<span>he image of the mirror is located 15 millimeters.</span>
The balanced chemical reaction is:
AgNO3 + NaCl = AgCl + NaNO3
We are given the amount of silver nitrate to be used for the reaction. This will be the starting point of our calculations.
15.0 mol AgNO3 ( 1 mol AgCl / 1 mol AgNO3 ) = 15.0 mol AgCl
Answer:
b. 0.47 moles Ca.
Explanation:
Hello there!
In this case, since 1 mole of any element contains 6.022x10²³ atoms of the same, it is possible for us to compute the moles in 2.8x10²³ atoms of calcium via the Avogadro's number:
Therefore, the answer would be b. 0.47 moles Ca.
Best regards!
