**Explanation:**

Sulfonation of naphthalene, C10H8, results in two products. One product is kinetically favored and predominates in the beginning of the reaction. Because the reaction is reversible, eventually the kinetically slower but thermodynamically favored product predominates. Draw the structure of these two products. (The naphthalene ring is already drawn for you. Do not change the double bond configuration in the given structures.)

The **green house gases** in the atmosphere can change the behavior of **energy** on earth. Thus** i agree** with this statement.

The **green house effect** is defined as a process by which the **radiations** from the sun are absorbed by the **green house gases** like methane, **Chloro fluoro carbons **and not reflected back into the space. This makes the surface as** insulator **and prevents it from **freezing**.

Due to the increased level of green house gases, the **temperature** of the earth increases considerably and thereby causes** global warming**, **depletion of ozone layer**, smog and air pollution, etc.

It is the natural **green house effect** which affect the behaviour of heat energy radiated by the sun. The green house gases never let the **radiations** escape from the earth and increase the **surface temperature **of earth. This leads to **global warming**.

Thus green house gases affects the **solar energy**.

**Answer:**

I agree

**Explanation:**

because the sunlight passes through the atmosphere and is absorbed by earth's surface.

**Answer:**

See explanation

**Explanation:**

In this case, we have 2 types of reactions. is a strong base but only has 2 carbons therefore we will have ** less steric hindrance** in this base. So, the base can remove hydrogens that are bonded on carbons 1 or 6, therefore, we will have a

For the we have ** more steric hindrance**. So, we can remove only the hydrogens from carbon 7 and we will produce a

An electrochemical cell is based on these two half-reactions: Oxidation:Reduction:

Ni(s)VO2+(aq,0.083M)+2H+(aq,1.1M)+e−→→Ni2+(aq,2.5M)+2e−VO2+(aq,2.5M)+H2O(l)

Calculate the cell potential under these nonstandard concentrations.

Express the cell potential to two decimal places and include the appropriate units.

**Answer:**

**Cell potential under non standard concentration is 4.09 v**

**Explanation:**

To solve this problem we need to use Nernst Equation because concentrations of the components of the chemical reactions are differents to 1 M (normal conditions: 1 M , 1 atm).

Nernst equation at 25ºC is:

where

E: Cell potential (non standard conditions)

= Cell potential (standard conditions)

n: Number of electrons transfered in the redox reaction

Q: Reaction coefficient (we are going to get it from the balanced chemical reaction)

For example, consider the following general chemical reaction:

aA + bB --> cC + dD

where

a, b, c, d: coefficient of balanced chemical reaction

A,B,C,D: chemical compounds in the reaction.

Using the previous general reaction, expression of Q is:

Previous information is basic to solve this problem. Let´s see the Nernst equation, we need to know: , n and Q

Let´s calcule potential in nomal conditions ():

1. We need to know half-reactions (oxidation and reduction), we take them from the chemical reaction given in this exercise:

Half-reactions: Eo (v):

+ e- --> -0.23

+ 2 e- +0.99

Balancing each half-reaction, first we are going to balance mass and then we will balance charge in each half-reaction and then charge between half-reactions:

Half-reactions: Eo (v):

2 * [ + e- --> ] -0.23

1 * [ + 2 e- ] +0.99

------------------------------------------------------------------- -------------

2 + 2e- + Ni --> 2 + + 2e- 0.76 v

Then global balanced chemical reaction is:

2 + Ni --> 2 +

and the potential in nomal conditions is:

= 0.76 v

Also from the balanced reaction, we got number of electons transfered:

n = 2

2. Calculate Q:

Now using previous information, we can establish Q expression and we can calculate its value:

From the exercise we know:

3. Use Nernst equation:

Finally, we replace all these results in the Nernst equation:

Cell potential under non standard concentration is **4.09 v**

To calculate the cell potential under nonstandard conditions, we need to apply the **Nernst Equation**. This involves finding the reaction quotient (Q) from the given concentrations and then subtracting a value derived from Q and the number of electrons transferred, from the cell potential under standard conditions.

For calculating the** cell potential **under nonstandard conditions for an electrochemical cell, we need to use the Nernst equation. In this case, the Nernst Equation is Ecell = E∘cell - (0.0592/n) * logQ, where Q, the reaction quotient, is the ratio of the concentrations of the products to the reactants raised to their stoichiometric coefficients.

Given the half-cell reduction potentials, we can calculate the cell potential under standard conditions (E°cell) by subtracting the potential of the anode from the potential of the cathode (E°cell = Ecathode - Eanode = 0.99V - (-0.23V), resulting in E°cell = 1.22V.

Next, Q = [Ni2+]/([VO2+]×[H+]²), substituting the given concentrations, Q = (2.5)/(0.083×1.1²).

After calculating Q, we substitute all known values into the Nernst Equation and solve for Ecell. Hence, the cell **potential** under these nonstandard conditions can be calculated.

PLEASE HELP

First of all altitude, is the height of anything especially above sea level. So when your at different altitudes its hotter or colder. Like outside the higher that water gets it freezes cause it going all the way up to the cold mountains and as you go down in altitude depending on the day it gets warmer and evaporates.

Sorry, I don't know if I explained it well, hope I helped you out! :)

**Answer:**

Based on the given reaction, it is evident that the reaction is endothermic as indicated by a positive sign of enthalpy of reaction. Thus, it can be stated that the favoring of the forward reaction will take place by upsurging the temperature of the reaction mixture.

Apart from this, based on Le Chatelier’s principle, any modification in the quantity of any species is performed at equilibrium and the reaction will move in such an orientation so that the effect of the change gets minimized. Therefore, a slight enhancement in the concentration of the reactant will accelerate the reaction in the forward direction and hence more formation of the product takes place.
