The resulting atomic number of an element that emits 1 alpha particle, 1 positron, and 3 beta particles is

Chemistry

Natalka [10]3 years ago
4 0

Answer: -

Thus the resulting atomic number of an element that emits 1 alpha particle, 1 positron, and 3 beta particles is the same as original.

Explanation: -

Let the mass number be A and the atomic number be Z.

When an alpha particle is emitted, the mass number decreases by 4 and the atomic number decreases by 2.

Thus after alpha particle the new mass number = A - 4

Thus after alpha particle the new atomic number = Z - 2

When a positron is emitted, the atomic number only decreases by 1.

Thus after positron emission the new mass number = A - 4

Thus after positron emission the new atomic number = Z - 2 - 1

= Z - 3

When a beta particle is emitted, the atomic number increases by 1.

For 3 beta particles, the atomic number will increase by 3.

Thus after beta particle emission the new mass number = A - 4

Thus after beta particle emission the new atomic number = Z - 3+3

= Z

Thus the resulting atomic number of an element that emits 1 alpha particle, 1 positron, and 3 beta particles is the same as original.

What is the approximate bond angle around the central carbon atom in acrolein?
Soloha48 [4]

Answer:

The approximate bond angle around the central carbon atom in acrolein is 120°.

Explanation:

The structure of acrolein is shown in the attachment. From the structure, we can deduce that the central carbon atom is in an sp2 hybridization (Atoms with a double bond hybridize in an sp2 fashion).

Atoms with sp2 hybridization have trigonal planar geometry, in this kind of hybridization, bonds are oriented the farthest away possible from each other, to minimize overlapping and the angle that allows that is 120°.

Which is the least dense?<br><br> copper<br><br> mercury<br><br> water<br><br> wood
tamaranim1 [39]
Least dense means the one that is at the top. Wood floats on top of water, so wood would be the least dense. Water has a density of 1 and the others would all sink, so they're more dense. The answer is wood

Two compounds are standing at the same temperature. Compound "A" is evaporating more slowly than compound "B." According to the
frosja888 [35]

Answer:

Option D) Compound B may have a lower molecular weight.

Explanation:

Compound A and B are standing at the same temperature yet compound A is evaporating more slowly than compound B.

This simply indicates that compound B have a lower molecular weight than compound A.

This can further be seen when gasoline and kerosene are placed under same temperature. The gasoline will evaporate faster than kerosene because the molecular weight of the gasoline is low when compared to that of the kerosene.
