Using the activity series provided. Which reactants will form products?

2 answers:

6 0

All the reactions given are single displacement reactions and can only occur if the metal is more reactive than the metal in the salt. In the first equation, silver is much less reactive than sodium so no reaction occurs. Same goes for the other 2. However the last equation will occur as iron is more reactive than copper and will displace it out of solution, forming copper metal and iron nitrate. Therefore the 4th reaction will form products

Name the following compound: HNO3 Hydrogen nitrate Hydrogen nitrite Nitric acid Nitrous acid

wariber [46]

The compound HNO3 is called nitric acid.

HNO3 is a covalent compound and a strong acid which ionizes in water into H+ (proton) and NO3- (nitrate ion).

HNO3 (aq) ↔ H+(aq) + NO3-(aq)

Ans: HNO3 = Nitric Acid

[On a side note: Nitrous acid is HNO2]

Morphine is an effective pain killer but is also highly addictive. calculate the ph of a 0.115 m solution of morphine if its pkb

VMariaS [17]

Answer is: pH value of morphine is 10.64.
Chemical reaction: C₁₇H₁₉NO₃ + H₂O → C₁₇H₁₉NO₃H⁺ +OH⁻.
Kb(C₁₇H₁₉NO₃) = 10∧(-5,79) = 1,62·10⁻⁶.
c(C₁₇H₁₉NO₃) = 0,115 M.
Kb(C₁₇H₁₉NO₃) = c(OH⁻) · c(C₁₇H₁₉NO₃H⁺) ÷ c(C₁₇H₁₉NO₃).
c(OH⁻) = c(C₁₇H₁₉NO₃H⁺) = x.
1,62·10⁻⁶ = x² ÷ (0,115 - x).
Solve quadratic equation: x = c(OH⁻) = 0,000431 M.
pOH = -log(0,000431 M) = 3,36.
pH = 14 - 3,36 = 10,64.

Which one of the following reactions IS NOT balanced? 1. 2 KNO3 + 10 K → 5 K2O + N2 2. 2 SO2 + O2 → 2 SO3 3. SF4 + 3 H2O → H2SO3

Delicious77 [7]

Answer:

2 KNO₃ + 10 K → 5 K₂O + N₂ (option 1)

Explanation:

1. 2 KNO₃ + 10 K → 5 K₂O + N₂

We have in reactant side:

2 K, 2N, 6O and 10 K. In conclussion, 12 K, 2N and 6 O

We have in product side.

10 K, 5O and 2 N

This equation is unbalanced

2. 2 SO₂ + O₂ → 2 SO₃

In reactant side we have 2 S and 6 O

In product side we have 2 S and 6 O

3. SF₄ + 3 H₂O → H₂SO₃ + 4 HF

In reactant side we have 1 S, 4F, 6 H and 3 O

In product side we have 1 S, 4F, 6 H and 3 O
