Question

Take a magnesium ribbon and some sulphur powder. Burn the magnesium ribbon. Collect the ashes formed and dissolve them in water. Test the resultant solution with both red and blue litmus paper. Now burn sulphur powder. Place a test tube over the burning sulphur to collect the fumes produced. Add some water to the above test tube and shake. Test this solution with blue and red litmus paper.
A. What is the nature of the product formed on burning magnesium either acidic or basic
B. What is the nature of the product formed on burning sulphur either acidic or basic
C. Name the product formed in both the reaction
D. Write the chemical equations for these reactions ​

Answer 1

Explanation:

AnSwEr :-

2 or -6.

Given :-

The distance between the points A(2, -2) and B(-1, x) is equal to 5.

To Find :-

Value of x

SoluTion :-

Here,

x1 = 2

y1 = -2

x2 = -1

y2 = x

Formula for finding distance between two points is :-

\sqrt{{(x2 - x1) {}^{2} } + (y2 - y1) {}^{2} }

(x2−x1)

2

+(y2−y1)

2

Put the values in the formula :-

√ (- 1 - 2)² + {x - (-2)}² = 5

→ √ { (-3)² + (x + 2)² } = 5

→ √{ 9 + (x + 2)² } = 5

→ 9 + (x + 2)² = 25

→ (x + 2)² = 16

→ x + 2 = ± 4

_____________________

x + 2 = 4

→ x = 4 - 2

→ x = 2

_____________________

x + 2 = - 4

→ x = - 4 - 2

→ x = - 6

Hence, the value of x is 2 or -6.
