Technically, pickles may be considered both a fruit and a vegetable. While they are made from cucumbers, which are a vegetable, the U.S. Supreme Court ruled them a â€˜fruit of the vineâ€™ because of their seeds.

The reaction uses B) 9.0 g Br₂.

iron + bromine ⟶ product

2.0 g + x g ⟶ 11.0 g

According to the Law of Conservation of Mass, the total mass of the reactants must equal the total mass of the products.

∴2.0 + x = 11.0

x = 11.0 – 2.0 = 9.0

The reaction uses 9.0 g Br₂.

Which metal will react spontaneously with Cu2+ (aq) at 25°C?

Gwar [14]

Answer:

Explanation:

The standard reduction potentials are

E°/V

Au³⁺(aq ) + 3e⁻ ⟶ Au(s); 1.42

Hg²⁺(aq) + 2e⁻ ⟶ Hg(l); 0.85

Ag⁺(aq) + e⁻ ⟶ Ag(s); 0.80

Cu²⁺(aq) + 2e⁻ ⟶ Cu(s); 0.34

Mg2+(aq) + 2e- ⟶ Mg(s); -2.38

The more negative the standard reduction potential, the stronger the metal is as a reducing agent.

Mg is the only metal with a standard reduction potential lower than that of Cu, so

Only Mg will react spontaneously with Cu²⁺.

Calculate either [ H 3 O + ] or [ OH − ] for each of the solutions.

STALIN [3.7K]

Answer: Solution A : $[H_3O^+]=0.300\times 10^{-7}M$

Solution B : $[OH^-]=0.107\times 10^{-5}M$

Solution C : $[OH^-]=0.177\times 10^{-10}M$

Explanation:

pH or pOH is the measure of acidity or alkalinity of a solution.

pH is calculated by taking negative logarithm of hydrogen ion concentration and pOH is calculated by taking negative logarithm of hydroxide ion concentration.

$pH=-\log[H_3O^+]$
