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.

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.

The stock concentration of NaOH is 0.5M. 0.5M = 0.500mol/1.0L.
valentinak56 [21]

Answer:a) 0.1 mole. b) 4g. c) 2% d)  196 mL

Explanation: in 200mL , 0.1mole

mw NaOH = 40g/mol —> 4g in 0.1 mole

4g in 200mL so 2g in 100mL

density NaOH = 1g/mL so if 4g in 200 mL,  4mL , 196 mL water

Andi performs the calculation that is shown below.
rodikova [14]

Answer: 3.59

Explanation:

(2.06)(1.743)(1.00)

2.06 × 1.743 × 1.00

= 3.59058

Two of the multiplied digits are represented in 3 significant figures. Therefore, for correct representation, the result of the product should be written to three significant figures.

3.59058 to 3 significant figures:

First three digits = 3.59

Fourth digit '0' is less than 5, and thus rounded to 0 with other succeeding digits

Therefore, (2.06)(1.743)(1.00) to 3 significant figures equals :

3.59
