Mass<span> is the amount of matter an </span>object<span> has. We often use a triple-balance beam to </span>measure mass<span>. A triple-beam balance gets its name because it has three beams that allow you to move known </span>masses<span>along the beam. Here is a picture of a triple beam balance.</span>
Heat lost= heat gained, so if x is the equilibrium temperature heat lost is 160(90-x) and heat gained is 10(x-10).
14400-160x=10x-100, 170x=14500, x=14500/170=85.3℃.
The balance chemical equation is follow,
2 I⁻ + SO₄²⁻ + 4 H⁺ → I₂ + SO₂ + 2 H₂O
According to this reaction, 2 moles of I⁻ reacts with 1 mole of SO₄²⁻ to produce 1 mole of I₂ and 1 mole of SO₂.
Result:
So with the formation of 1 mole of I₂, 1 mole of SO₂ is produced.
