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

The explanation that correctly justifies the observation is that; Iron powder and sulfur powder combined physically; therefore, they retained their individual properties.

When substances are physically combined , they retain their individual properties because there was no change in their composition. They did not combine chemically.

Mixing the iron and sulphur did not change anything about the individual properties of those elements. The retain their individual properties.

Iron is magnetizable hence it was attracted by a magnet. Sulphur is not magnetizable so it remained unchanged.

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.
