Use the potential energy diagram shown to answer the following: Which letter shows the activation energy(without use of a catalyst)

Use The Potential Energy Diagram Shown To Answer The Following: Which Letter Shows The Activation Energy(without

Answers

Answer 1

Answer:

a

Explanation:

Activation energy is the minimum amount of energy that must be overcome before a reaction will proceed to product.

In the energy diagram, the thick line represent the uncatalyzed path while the broken line line indicates the catalyzed path.

In the diagram above, the letter between the reactant and the Peak of the diagram gives the activation energy. This letter is a.

Therefore, the activation energy for the uncatalyzed reaction is 'a'.

Answer 2
the answer to this question is a because yu use the diagram

Who invented the Periodic table? And why Periodic tables are useful?

Answers

Answer:

It also helps them understand how life works. It even helps them predict how new materials will behave. In 1869, Dmitri Mendeleev, a Russian chemist, proposed the periodic law and his first periodic table. He published this periodic table two years later in a textbook, The Principles of Chemistry.

Explanation:

Answer:

Dmitri Mendeleev, To summarize, the periodic table is important because it is organized to provide a great deal of information about elements and how they relate to one another in one easy-to-use reference. The table can be used to predict the properties of elements, even those that have not yet been discovered

How many lead (Pb) atoms will be generated when 5.38 moles of ammonia react according to the following equation: 3PbO+2NH3→3Pb+N2+3H2O?
A) 1.62 × 10^24
B) 4.86 × 10^23
C) 2.43 × 10^24
D) 4.86 × 10^24

Answers

Answer:D. Is the correct answer

Explanation:

Following are the calculation of the lead (Pb) atoms:

Balanced reaction:  

[tex]\bold{3PbO+2NH_3\longrightarrow 3Pb+N2+3H2O}\\\\[/tex]

[tex]\bold{mol\ NH_3 \longrightarrow mol \ Pb \longrightarrow atoms \ Pb}[/tex]

Calculating the number of atoms in Pb that will be generated:

[tex]=5.38 \ mol \ NH_3 \times \frac{3\ mol\ Pb}{2 \ mol NH_3} \times \frac{6.022 \times 10^{23} \times pb}{1 \ mol \ pb}\\\\ = 4.86 \times 10^{24} \ atoms\ in \ Pb\\\\= 4.86 \times 10^{24} \ atoms \\[/tex]

Therefore, the answer is "Option D"

First you have to calculate the number of moles of caco3 ! Use n=m/M ! YOH will get 0.1 moles ! By using stiochiometry you will get


O3/Caco3 = 48/100 (molar masses ) = x/0.1. ( using moles ) then you will get x = 0.048 moles

the diagram shows an electrochemical cell with copper (left) and zinc (right) strips.

**Label all parts (1-9), including the solutions in each beaker and the connecting tube
**Label which cell is the cathode and which cell is the anode include the charge on each strip
**Show, or describe in detail, the flow of electrons
**Describe what type of electrochemical cell is pictured. Explain how the cell works Include the oxidation the oxidation half-reacions in your explanation

Answers

Answer:

Explanation:

1- Cathode 2- copper electrolyte solution usually (CuSO4) 3- Cu half cell 4- bulb (when lighted, shows the current is flowing) 5- Zn half cell 6- Zn electrolyte solution 7- connecting wires 8- anode (Zn) 9-salt bridge

2- the copper-(Cu) electrode is the cathode and the zinc-(Zn) electrode will be the anode. This is because the cathode is negatively charged (while Cu is positively charged, so it attracts) and the anode is positively charged (while Zn will be negative)

3- the electrons flow from the anode, where oxidization takes place, to the cathode, where reduction reactions take place.

That's the best i can do. Hope it helps.

Answer:

Explanation:

• Label all parts (1–9), including the solutions in each beaker and the connecting tube.

1. Copper strip

2. Cu2+(aq) (copper electrolyte solution or copper nitrate)

3. Cathode compartment  

4. Light bulb  

5. Anode compartment  

6. Zn2+ (aq) (zinc electrolyte solution or zinc nitrate)  

7. The connecting wires or the external circuit  

8. Zinc strip  

9. Salt bridge  

• Label which cell is the cathode and which cell is the anode. Include the charge on each strip.

The copper strip is the cathode and the zinc strip is the anode. The anode is positively charged and the cathode is negatively charged. This is because the cathode attracts a positive charge and the anode attracts a negative charge.  

• Show, or describe in detail, the flow of electrons.

The atoms from the zinc strip are oxidized into zinc ions, (the anode is where oxidation occurs). The electrons in the anode then travel through the wire to the copper strip. The electrons then merge with the copper ions in the solution creating copper metal (the cathode is where reduction occurs).  

• Describe what type of electrochemical cell is pictured. Explain how the cell works. Include the oxidation and reduction half-reactions in your explanation.  

This is a voltaic or galvanic cell. It works by using spontaneous oxidation-reduction reaction to generate electricity.  

Zn(s) --- Zn2 + (aq) + 2e-  

Cu2 + (aq) + 2e- --- Cu(s)
