Construct a pair of conversion factors that relate moles of s to moles of al2 (so4)3.

Explanation:

First conversion factor: moles of SO₄ per mole of Al₂(SO₄)₃.

3 mol SO₄ / mol Al₂(SO₄)₃

Second conversion factor: moles of S per mole of SO₄.

1 mol S / mol SO₄

Altogether:

(3 mol SO₄ / mol Al₂(SO₄)₃) × (1 mol S / mol SO₄) = 3 mol S / mol Al₂(SO₄)₃

pure water does not conduct electricity very well. however, when certain substances are dissolved in water, the solution does conduct electricity. you can make a simple device that shows how well a solution conducts electricity. this device uses a flashlight bulb to indicate how well the solution conducts electricity. the better the solution conducts electricity, the brighter the bulb will glow.

explanation:

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.
