Explain the following: a) Vulnerability Analysis b) Zoning and land use management

Answer»

a) Vulnerability Analysis: Assessing vulnerabilities of a megacity are fundamental to enabling counteractive measures before an expected earthquake disaster as well as preparing for the post-earthquake response. An example of vulnerability analysis is of a remote sensing system set up to assess the vulnerability of a megacity and to assess the risk of a hazard turning into a disaster in that megacity.

b) Zoning and Land use Management: Zoning is a method of land use planning done by local governments. The word is derived from the practice of designating permitted uses of land based on mapped zones which separate one set of land uses from another.

Explain Conditional formatting with a help of suitable example.

Conditional formatting allows to change the formatting (font color, border, shading) of the cells based on the values in it. One or more cells can be selected, and create rules (conditions) for when and how those cells are formatted. The conditions can be, based on the selected cell's contents, or based on the contents of another cell.

“Sodium cannot be kept open in atmospheric air, and cannot be stored in water. So it is stored in kerosene.” Give explanation for the above statement with its chemical equation.

Answer»

Sodium which is placed above in the reactivity series reacts vigorously with water and oxygen. 

4Na (s) + O2 (g) → 2Na2O (s) 

2Na (s) + 2H2O (l) → 2NaOH (aq) + H2 (g)

This NaOH reacts with CO2 in the atmospheric air and forms sodium carbonate. 

2NaOH (s) + CO2 (g) → Na2CO3 + H3O (l) To avoid the reaction with O2 , H2O and CO2 , sodium is stored in kerosene.

Sodium reacts vigorously with water and oxygen.

Chemical Equations:

4Na(s) + O2(g) ⟶ 2Na2​O(s)

2Na(s) + 2H2​O(l) ⟶ 2NaOH(aq) + H2(g)

This NaOH reacts with CO2​ present in the atmosphere to form sodium carbonate.

Chemical Equations:

2NaOH(s) + CO2(g) ⟶ Na2CO3(s)​ + H2​O(l)

To avoid the reaction with O2​, H2​O and CO2​, which is highly exothermic (can also produce flames), sodium is stored in kerosene.

The angle between  two vector  of magnitude  12 and 18 units when the resultant  is 24 unitsA) 63 degree 57 minB) 75degree 52 degreeC) 82 degree 3minD) 89degree 16minIs there  is way to find the uncommon degrees in maths   or it  is only possible  by using calculatator ????

Answer»

Correct option is (B) 75.52 degree

Explanation:

As we know that
R² = A² + B² + 2ABcos(θ) 

24² = 12² + 18² + 2*12*18cos(θ) 
6(4²) =62 (2² + 3² + 2*2*3cos(θ))
Cos 
θ = 3/12 = 0.25
we can only tick the value by graph of cos
θ if there is greater difference of angle in options otherwise use calculator.

θ = 75.52 degree.

The direction of electron flow in certain galvanic cells are given below. (Symbols are not real) i. B → A, ii. E → C, iii. D → E, iv. A → D. a. Arrange the metals A, B, C, D and E in the decreasing order of their reactivity. b. Choose the reaction taking place at ‘C’ in cell (ii) E → C. Give the reason. i. C+ (aq) + le- → C(s) ii. C (s) → C+ (aq) + le-iii. C (s) → C+ (aq) + le-

Answer»

a. B, 

A, 

D, 

E, 

C. 

b. C+ (aq) + le- → C (s) is the correct equation. 

Because ‘E’ has higher reactivity than. So ‘C’undergoes reduction.

Take 10 mL each of hard water in two test tubes. Add a few drops of soap solution in the first test tube and add the same amount of detergent solution in the second one. Shake both the test tubes well. What do you observe? Which test tube contains more foam?

Answer»

Soap does not lather well in hard water. The hardness of water is due to dissolved calcium and magnesium salts in it. These salts react with soap to form insoluble compounds resulting in the decrease of lather. But detergents do not give insoluble components on reaction with these salts. Hence detergents are more effective than soaps in hard water.

96695.

a. What are the changes that can be observed with the iron rod and the colour of copper sulphate solution? b. Write the equations of the oxidation and reduction reactions. c. What will be the change if silver rod is used instead of iron rod? What is the reason?

Answer»

a. Copper is deposited on iron and the blue.colour of copper sulphate solution decreases. 

b. Cathode – Cu2+ (aq) + 2e- → Cu (s) (Reduction) 

Anode – Fe2+ (s) → Fe (aq) + 2e- (Oxidation) 

c. No change occurs, Reactivity of silver is less than that of copper. In the reactivity series, the position of silver is below copper.

Take cold water and Hot water in two test tubes, Add one or two drops of phenolphtha lein in it. Drop equally sized Mg ribbon in it.a. In which test tube pink colour occured sharply? b.Why did pink colour appear in that test tube so early? c. Which gas evolved out from both test tubes? d. Write balanced equation for the above mentioned reaction.

Answer»

a. Pink colour occurred sharply in the test tube with hot water. 

b. Temperature is a factor that affects the rate of a reaction. When heated the kinetic energy of molecules increases and hence the rate of chemical reaction also increases which causes the pink colour to appear early.
