Answer:

Food Processing Plant

Explanation:

The lysosomes contain digestive enzymes that break down large food particles into sugars and other simple substances that can be used more easily as does a food processing plant that processes large quantities of food entering the city into smaller packages that can be used more easily.

If 190.5 grams of copper metal reacts, how many grams of silver metal will be produced?

Lubov Fominskaja [6]

Answer:

646.8 g

Explanation:

It really depends what salt silver cation makes in the context of this problem. In this problem, we have a single displacement reaction in which copper metal displaces silver cation from a salt to produce silver metal. Based on the charge of the anion in the salt, we may have differently balanced chemical equations.

Since silver cation mostly makes insoluble salts and we need a soluble one for a single displacement reaction, we'll use silver nitrate as our example, as it's the most common soluble silver salt. We have the following reaction:

$Cu(s)+2AgNO_3(aq)\rightarrow Cu(NO_3)_2(aq)+2 Ag(s)$

Notice that 1 mole of copper reacts to produce 2 moles of silver. This may be mathematically written as:

$\frac{n_{Cu}}{1}=\frac{n_{Ag}}{2}$

Express moles as a ratio between mass and molar mass:

$\frac{m_{Cu}}{M_{Cu}}=\frac{1}{2}\cdot\frac{m_{Ag}}{M_{Ag}}$

Rearrange the equation for the mass of silver metal:

$m_{Ag}=\frac{2m_{Cu}}{M_{Cu}}\cdot M_{Ag}$

Substitute the given data:

$m_{Ag}=\frac{2\cdot 190.5 g}{63.546 g/mol}\cdot 107.87 g/mol = 646.8 g$

For the reaction shown, identify the element oxidized, the element reduced, the oxidizing agent, and the reducing agent. KNO3 →

Vinvika [58]

Answer : The oxidizing element is N and reducing element is O.

$KNO_{3}$ is act as an oxidizing agent as well as reducing agent.

Explanation :

An Oxidizing agent is the agent which has ability to oxidize other or a higher in oxidation number.

Reducing agent is the agent which has ability to reduce other or lower in oxidation number.

The given reaction is :

$KNO_{3} \rightarrow KNO_{2} +O_{2}$

$KNO_{3}$ act as an oxidizing agent.

The oxidation number of N in $KNO_{3}$ is calculated as:

(+1)+(x)+3(-2) = 0

x = +5

And the oxidation number of N in $KNO_{2}$ is calculated as:

(+1)+(x)+2(-2) = 0

x = +3

From the oxidation number method, we conclude that the oxidation number reduced this means $KNO_{3}$ itself get reduced to $KNO_{2}$ and it can act as an oxidizing agent.

$KNO_{3}$ act as a reducing agent.

$KNO_{3} \rightarrow KNO_{2} +O_{2}$

The oxidation number of O in $KNO_{3}$ is calculated as:

(+1)+(+5)+3(x) = 0

x = -2

The oxidation number of O in $O_{2}$ is Zero (o).

Now, we conclude that the oxidation number increases this means $KNO_{3}$ itself get oxidized to $O_{2}$ and it can act as reducing agent.
