The compound ethylene (C2H4) is represented by this diagram. What statement best describes the arrangement of the atoms in an et
Effectus [21]

<u>Answer:</u> The correct answer is two electrons are shared between each hydrogen atom and the carbon atom bonded to it, and four electrons are shared between the carbon atoms.

<u>Explanation:</u>

Ethylene is a compound given by the chemical formula H_2C=CH_2.

The bond present between hydrogen and carbon atoms or carbon and carbon atoms are covalent bonds. A covalent bond is formed by the sharing of electrons between the atoms combining.

A double bond is present between carbon and carbon atoms. So 2 pairs of electrons are shared which means in total of 4 electrons are shared.

Bond present between hydrogen and carbon atoms are single bonds. So, a pair of electrons is shared which means that in total of 2 electrons are shared.

Hence, the correct answer is two electrons are shared between each hydrogen atom and the carbon atom bonded to it, and four electrons are shared between the carbon atoms.

While playing football, Chris runs 4.5 m at 20⁰ south of west. If an opponent was trying to tackle him how far west and south wo
rewona [7]

Answer:

South = 1.5m

West =4.2m

Explanation:

Kindly see attached a rough draft of the situation

Step one

Given data

From the sketch the direction of the player is along the resultant of the triangle, corresponding to the Hypotenuse

Step two:

Hence for an opponent to tackle him towards the south, he must be at

sin θ= opp/hyp

sin 20=x/4.5

x=sin 20*4.5

x=0.342*4.5

x= 1.5m

Also, for an opponent to tackle him towards the south, he must be at

cos θ= adj/hyp

cos 20=y/4.5

y=cos 20*4.5

y=0.93*4.5

y= 4.2m

A 1.5V battery is connected to a small light bulb with a resistance of 3.5 what is the current in the bulb?
notka56 [123]

Technically, we don't have the information needed to calculate the current,
because you haven't mentioned the units of the 3.5 .

Since the 3.5 is a resistance, we strongly suspect ... and we'll therefore
assume ... that the  3.5  has the units of ohms.    Then . . .

  Current = (voltage) / (resistance)  =  (1.5/3.5) = <em>3/7 of an Ampere</em>.

                                                                   (429 mA, rounded)
