Answer:

Explanation:

Start with the number of grams of each element, given in the problem.

Convert the mass of each element to moles using the molar mass from the periodic table.

Divide each mole value by the smallest number of moles calculated.

Round to the nearest whole number. This is the mole ratio of the elements and is

Write two reactions showing nascent Hydrogen is more reactive than<br> molecular Hydrogen.
ratelena [41]

Answer:

1.) Nascent Hydrogen has more energy than Molecular Hydrogen.

2.) Nascent Hydrogen is are more on the side of atomic and since atoms are more active than molecules, Nascent Hydrogen becomes more reactive.

When an electron passes through the magnetic field of a horseshoe magnet, the electron's?
blsea [12.9K]

When an electron passes through the magnetic field of a horseshoe magnet, the electron's direction is changed.

Path of an electron in a magnetic field

The force (F) on wire of length L carrying a current I in a magnetic field of strength B is given by the equation:

F = BIL

But Q = It and since Q = e for an electron and v = L/t you can show that :

Magnetic force on an electron = BIL = B[e/t][vt] = Bev where v is the electron velocity

In a magnetic field the force is always at right angles to the motion of the electron (Fleming's left hand rule) and so the resulting path of the electron is circular.

Therefore :

Magnetic force = Bev = mv2/r = centripetal force

v = [Ber]/m

and so you can see from these equations that as the electron slows down the radius of its orbit decreases.

If the electron enters the field at an angle to the field direction the resulting path of the electron (or indeed any charged particle) will be helical. Such motion occurs above the poles of the Earth where charges particles from the Sun spiral through the Earth's field to produce the aurorae.

Why does the correct lewis structure of Co2 involve a double bond between each of the oxygen atoms and the carbon atom
kiruha [24]

Answer:

Because both carbon and oxygen are demanded to obey the octet's rule.

Explanation:

Hello.

In this case, recalling the Lewis dot structure of CO₂ which is basically:

O:=:C:=:O

We know oxygen has six valance electron whereas carbon four valence electrons, it means that oxygen needs two electrons in order to attain eight electrons and carbon needs four electrons for the same purpose. In such a way, as carbon dioxide contains one carbon atom and two oxygen atoms we infer that each oxygen is providing two electrons for a total of four to allow the carbon obey the octet as well as oxygen and this is attained via two double bonds.

Best regards.
