Which of the following is not a correct chemical equation for a double displacement reaction? (D?)

emmasim [6.3K]

The correct answer would be the last option. A double displacement type of reaction involves the switching of places the cations and anions accordingly. The given reaction is erroneous since in the product side the anions and cations are being paired which would not make sense. The correct reaction should be

4NaBr + Co(SO3)2 yields <span>CoBr4 + 2Na2SO3</span>

When a pendulum swings, if it is not continuously pushed it will not stop eventually because some of its energy is changed into.

Vladimir79 [104]

Well, there is kinetic energy when the object is in motion. But it will stop eventually because that energy is converted into thermal energy, or heat.

What mass of cu(s)cu(s) is electroplated by running 14. 5 aa of current through a cu2 (aq)cu2 (aq) solution for 4. 00 hh?

galina1969 [7]

The mass of Copper electroplated is 68.76 g

<h3>What is electroplating?</h3>

The process of plating a metal onto another is known as electroplating.

It is often used to prevent corrosion of metal or for the decorative purposes

In this process, electric current is passed through an aqueous solution containing dissolved cations.

The dissolved cations are reduced developing a thin metal coating on the electrode.

At cathode,

$Cu^{2+}(aq) + 2e^-\rightarrow Cu(s)$

Current, I = 14.5 A

Time, t = 4 hrs = 4×60×60 = 14400 sec

Charge, q = It = 14.5×14400= 208800 C

Copper metal deposited by 2×96487 C = 63.55 g

Copper metal deposited by 208800 C = $\frac{63.55 \times208800}{2\times96487}$

= 68.76g

Hence, The mass of Copper electroplated is 68.76 g

For the reaction represented by the equation 2KClO3 → 2KCl + 3O2, how many grams of potassium chlorate are required to produce 1

Vikentia [17]

The grams of potassium chlorate that are required to produce 160 g of oxygen is 408.29 grams

<u><em>calculation</em></u>

2 KClO₃→ 2 KCl + 3O₂

Step 1: find the moles of O₂

moles = mass÷ molar mass

from periodic table the molar mass of O₂ = 16 x2 = 32 g/mol

moles = 160 g÷ 32 g/mol = 5 moles

Step2 : use the mole ratio to determine the moles of KClO₃

from equation given KClO₃ : O₂ is 2:3

therefore the v moles of KClO₃ = 5 moles x 2/3 = 3.333 moles

Step 3: find the mass of KClO₃

mass= moles x molar mass

from periodic table the molar mass of KClO₃

= 39 + 35.5 + (16 x3) =122.5 g/mol

mass = 3.333 moles x 122.5 g/mol =408.29 grams
