15.9 grams is the amount of copper sulfate this reaction will produce.

Given:

  • The reaction between copper and sulfur:

2Cu +S\rightarrow Cu_2S

  • 12.7 grams of copper completely reacts with 3.2 grams of sulfur to give copper sulfide.

To find:

The mass of copper sulfide produced

Solution

Mass of copper used by the scientist = 12.7 g

Mass of sulfur used by the scientist = 3.2 g

Mass of copper sulfide this reaction will produce. =?

According to the law of conservation of mass:

Total mass of reactants = Total mass of products

The total mass of reactants in the reaction = R = 12.7 g + 3.2 g = 15.9 g

The total mass of product formed in the reaction = P

P = R = 15.9 g

Mass of copper sulfide this reaction will produce = 15.9 g

15.9 grams is the amount of copper sulfate this reaction will produce.

The rate at which a certain drug is eliminated by the body follows first-order kinetics, with a half life of 68 minutes. Suppose
viva [34]

Answer:

The concentration would be; 0.0038 μgmL

Explanation:

Half life, t1/2 = 68 minutes

Initial Conc. [A]o = 0.12/μgmL

Final Conc [A] = ?

Time. k = 340 minutes

ln[A] = ln[A]o - kt

t1/2 = ln2 / k

k = 0.693 / t1/2  = 0.693 / 68 = 0.01019

ln[A] = ln (0.12) - 0.01019 (340)

ln[A] = -2.1203 -3.4646

ln[A] = -5.5849

[A] = 0.00375 ≈ 0.0038 μgmL

Answer:

Iron displaces copper ions

Explanation:

which means that iron in more reactive than copper.

(Fe2+) and cupric ion (Cu2 +) is converted into metallic copper. Fe (s) + Cu2 + (aq) —→ Fe2+ (aq) + Cu (s).
