5H₂SO₄ + 8NaI = 4I₂ + 4H₂O + H₂S + 4Na₂SO₄
S⁺⁶ + 8e⁻ = S⁻² f=8
2I⁻ - 2e⁻ = I₂
M(H₂SO₄)=98 g/mol
M(eqi)=98/8=12.25 g/mol
Answer:
statistics
Explanation:
statistics is the study of using numbers to express data
Because there are so many different values of numbers, it would be impractical to use 1Ω, 2Ω, 3Ω... etc... Using colored bands helps make reading it a little easier to the trained eye. There are hundreds of thousands, if not tens of millions of different resistors would need to exist to cover every value. So you just use something called "preferred values" with their resistance values posted on them instead.
Me no see nothing dudeeeeeeee
Answer:
Cl₂(g) + 2 KBr(aq) ⇒ Br₂(l) + 2 KCl(aq)
Explanation:
Let's consider the unbalanced single displacement reaction between chlorine and potassium bromide.
Cl₂(g) + KBr(aq) ⇒ Br₂(l) + KCl(aq)
We will start balancing Cl atoms by multiplying KCl by 2.
Cl₂(g) + KBr(aq) ⇒ Br₂(l) + 2 KCl(aq)
Finally, to get the balanced equation, we have to multiply KBr by 2.
Cl₂(g) + 2 KBr(aq) ⇒ Br₂(l) + 2 KCl(aq)
