Equations

Question 1

What is the first equation NaI undergoes with H2SO4?

Answer 1

NaI + h2So4 -> HI + NaSo4

Question 2

What is the second reaction Iodine undergoes with H2SO4?

Answer 2

2HI(g) + H2so4(aq) -> I2(g) + SO2(g) + 2H20 (l) Choking gas of so2 and purple vapor of i2

Question 3

What is the third reaction iodine undergoes with H2SO4?

Answer 3

6HI(g) + H2so4 (aq) -> 3I2 (g) + S(s) + 4h20 yellow solid of S

Question 4

What is the fourth reaction iodine undergoes with H2SO4?

Answer 4

8HI(g) + H2SO4(aq) -> 4I(g) + H2S(s) +4H20(l) H2s has a strong smell of bad eggs.

Question 5

What is the reaction iodine undergoes with SO2?

Answer 5

SO₂ (g) + 2HI (g) → H2S (g) + I2 (s) + H2O (l)

Question 6

What happens in the reaction of water and chlorine?

Answer 6

disproportionation reaction cl goes from 0 in cl2 to -1 in HCl and +1 IN HCLO
Cl+ H20 = HClO + HCl

Question 7

What happens in the presence of UV light in the reaction between water and chlorine?

Answer 7

• Chlorine is bubbled through water in the presence of sunlight.
  2H20 + 2Cl2 = 4H +4Cl- +O2

Question 8

What happens in the reaction of chlorine with cold sodium hydroxide?

Answer 8

Cl2 + 2 NaOH -> NaCl + NaClO +H20(l)

Question 9

how do you calculate the KC constant?

Answer 9

[C] ^ D[D] ^D / [A] ^A [B] ^B

Question 10

How do you calculate the enthalpy change?

Answer 10

enthalpy change = q/ number of moles

Question 11

how do you calculate q?

Answer 11

q= mass x specific heat capacity x change in temperature
