9.	Mr . Sharma was trying to identify an unknown element X with which when placed in dilute hydrochloric acid a reaction occurs a brisk efficiency was seen answer the question:a) give a balanced equation
Answer» Step-by-step explanation: Q1. You have been provided with three test tubes, one of them contains DISTILLED water and the other two contain an acidic solution and a basic solution respectively. If you are GIVEN only RED litmus paper; how will you identify the contents of each test tube? Ans. Add few drops of solution from all three test tubes on the red litmus paper separately. The solution which turns red litmus to blue contains basic solution. Use this blue litmus paper to test the solutions in other two test tubes. The solution from the test tube which turns blue litmus paper to red will be the acidic solution and solution of the test tube which do not change either red or blue litmus paper contain water. Q2. Why should curd and sour substances not be kept in brass and copper vessels? Ans. Curd and sour substances contain acids which can react with copper vessels and brass to form toxic compounds. Q3. Which gas is usually liberated when an acid reacts with a metal? Illustrate with an example. How will you test for the presence of this gas? Ans. When an acid react with a metal it liberates hydrogen gas. E.g., Zn(s) + 2HCL(AQ) → ZnCl2 (aq) + H2(g) To test the presence of H2 gas, bring a burning splinter near the mouth of the test tube where H2 gas is released, the match stick bums with a pop sound.

1. If the circumference of a circle is 220 m, find its:(i) Diameter1(ii) Areafo

Answer»

Answer:

Step-by-step explanation:

here's your answer:

GIVEN:

CIRCUMFERENCE = 220 m

To find:

Diameter and area

Solution:

First it is necessary to find radius

Circumference = 2πr

220 = 2× 22/7 × r

220 × 7 / 2 × 22 = r

5 × 7 = r ( After cancellation)

35 = r

Therefore r is 35 m

Diameter = 2r

= 2 × r

=2 × 35

= 70

Therefore Diameter is 70 m

Area = πr^2

= 22/7 × 35 × 35

= 22 × 5 × 35

= 3850 m^2

Hope this helps ☺️

One side of parallelogram is 18cm and its area is 153 sq. cm. Find the distance of the given side from its opposite side.

Answer»

☆ Solution ☆

Given :-

One side of parallelogram is 18cm and its area is 153 SQ. cm

To FIND :-

The distance of the given side from its opposite side.

Step-by-Step-Explaination :-

LET side of the parallelogram ( b ) = 18 cm

Distance between two parallel SIDES = altitude = h cm

As we know that ,

Area of parallelogram = b × h

Putting the respective value

Area of parallelogram = 18 cm × h = 153 cm²

Area of parallelogram = h = 153 cm²/ 18 cm

Area of parallelogram = 17 cm / 2

Area of parallelogram = 8.5 cm

HENCE,

Distance between two parallel sides (h) = 8.5 cm

48.	26) A boy's age is one-fourth that of his father. After24 years the boy will be half the age of his father.Find their present ages.
Answer» Answer : The present age of the boy is 12 years, and his FATHER age is 48 years. Step-by-step explanation : Let the boy's age be $\sf{ \dfrac{x}{4}}$ years and the father's age be x years. Given that, After 24 years, the boy will be HALF the age of his father. THEREFORE, Age of father, after 24 years = $\sf{ \dfrac{x + 24}{2}}$ And age of boy, after 24 years = $\sf{ \dfrac{x}{4}} + 24$ $\sf{ \longrightarrow \: \dfrac{x + 24}{2} = \dfrac{x}{4} + 24}$ $\sf{ \longrightarrow \: \dfrac{1}{2}x + 12 = \dfrac{1}{4}x + 24}$ $\sf{ \longrightarrow \: \dfrac{x}{2}+ 12 = \dfrac{x}{4}+ 24}$ $\sf{ \longrightarrow \: \dfrac{x}{2} - \dfrac{x}{4} = 24 - 12}$ $\sf{ \longrightarrow \: \dfrac{x}{4} = 12}$ $\sf{ \longrightarrow \: x = 12 \times 4}$ $\boxed{\sf{ \leadsto \: \sf{x = 48}}} \: \large{\red{ \star}}$ Therefore, the present age of his father is 48 years. Now, the age of boy is, We GOT x as 48, Therefore, $\sf{\longrightarrow \: \dfrac{48}{4}}$ $\boxed{\sf{\leadsto \: 12}} \: \large{\purple{ \star}}$ Therefore, the boy's age is 12 years.

26) A boy's age is one-fourth that of his father. After24 years the boy will be half the age of his father.Find their present ages.

Answer»

Answer :

The present age of the boy is 12 years, and his FATHER age is 48 years.

Step-by-step explanation :

Let the boy's age be $\sf{ \dfrac{x}{4}}$ years and the father's age be x years.

Given that, After 24 years, the boy will be HALF the age of his father.

THEREFORE,

Age of father, after 24 years = $\sf{ \dfrac{x + 24}{2}}$

And age of boy, after 24 years = $\sf{ \dfrac{x}{4}} + 24$

$\sf{ \longrightarrow \: \dfrac{x + 24}{2} = \dfrac{x}{4} + 24}$

$\sf{ \longrightarrow \: \dfrac{1}{2}x + 12 = \dfrac{1}{4}x + 24}$

$\sf{ \longrightarrow \: \dfrac{x}{2}+ 12 = \dfrac{x}{4}+ 24}$

$\sf{ \longrightarrow \: \dfrac{x}{2} - \dfrac{x}{4} = 24 - 12}$

$\sf{ \longrightarrow \: \dfrac{x}{4} = 12}$

$\sf{ \longrightarrow \: x = 12 \times 4}$

$\boxed{\sf{ \leadsto \: \sf{x = 48}}} \: \large{\red{ \star}}$

Therefore, the present age of his father is 48 years.

Now, the age of boy is, We GOT x as 48, Therefore,

$\sf{\longrightarrow \: \dfrac{48}{4}}$

$\boxed{\sf{\leadsto \: 12}} \: \large{\purple{ \star}}$

Therefore, the boy's age is 12 years.
