Answer:

4) x = 4

Explanation:

Using <u>Intersecting Chords Theorem</u>,

AB × CB = BE × BD

( 4x + 2) × 8 = 9 × ( 4x )
32x + 16 = 36x
16 = 36x -32x (Subtract)
16 = 4x (Divide both sides by 4)
x = 16/ 4 (Divide)
x = 4

Convert the following temperatures to degrees Celsius or Fahrenheit: (a) 95Â°F, the temperature on a hot summer day; (b) 12Â°F,

Elis [28]

Answer:

a) 35°C, the temperature on a hot summer day

b) -11.11°C, the temperature on a cold winter day

c) a 38.88°C fever

d) a furnace operating at 1011.11°C

e) 523.67°F ( theoretically the lowest attainable temperature )

Explanation:

°C = ( °F - 32 ) / 1.8
°F = ( 1.8 * °C ) +32

a) 95°F ⇒ °C = ( 95 - 32 ) / 1.8 = 35°C

b) 12°F ⇒ °C = ( 12 - 32 ) / 1.8 = -11.11°C

c) 102°F ⇒ °C = ( 102 -32 ) / 1.8 = 38.88°C

d) 1852°F ⇒ °C = ( 1852 -32 ) / 1.8 = 1011.11°C

e) 273.15°C ⇒ °F = ( 1.8 * 273.15 ) + 32 = 523.67°F

N the reaction Mg + 2HCl -> MgCl2 + H2 which element’s oxidation number does not change?

BartSMP [9]

Answer:- Oxidation number of Cl does not change as it is -1 on both sides.

Explanations:- oxidation number of Mg on reactant side is 0 as it is in its elemental form(not combined with another element).

Oxidation number of hydrogen in its compounds is +1, so if H is +1 in HCl the oxidation number of Cl is -1 as the sum has to be zero.

On product side, Mg oxidation number is +2 as the oxidation number of alkaline earth metals in their compounds is +2.

Two Cl are present in magnesium chloride, so if Mg is +2 then Cl is -1.

Oxidation number of H on product side is 0 as it is present in its elemental for, $H_2$ ,

So, it is only chlorine(Cl) whose oxidation number does not change for the given equation.
