During an experiment, iron powder and sulfur powder were mixed thoroughly and placed on a filter paper. When a magnet was moved

below the filter paper, the iron fillings stood up vertically as they were attracted by the magnet. The sulfur powder showed no change in position. Which of the following correctly justifies the observation? Iron and sulfur formed a compound; therefore, they lost their individual properties. Iron and sulfur formed a compound; therefore, they retained their individual properties. Iron powder and sulfur powder combined physically; therefore, they lost their individual properties.

Answer:

Iron powder and sulfur powder combined physically; therefore, they retained their individual properties.

Explanation:

Iron combines with sulfur physically as such there is no change in the individual chemical property of iron and sulfur. Iron has magnetic property and sulfur does not. So iron .gets attracted by the magnet and can be separated from sand. In a chemical process the reactants combine chemically to form a new product that has chemical properties distinct from the parent compounds. In a physical combination process no new chemical product is formed with distinct properties from the parent compound.

Reading the above graph to the nearest tenth of a milliliter, what is the volume of sodium hydroxide at the equivalence point?
Vlada [557]

Answer:

The volume of sodium hydroxide at the equivalence point is:

  • <u>14.9 mL of sodium hydroxide</u>.

Explanation:

<u>The equivalence point occurs when, in this case, the HCl is completely neutralized with the solution of NaOH, how you can see this doesn't occur in the last point but occurs in the nineteenth point, where the pH is no more acid (below to 7) but is 11 approximately</u>, then you must see in the X-axis from this point and you can see the volume is almost 15, by this reason I calculate the valor of 14.9 milliliters.
