In physics, a surface wave can occur along any boundary of two different substances. The seismic type of surface wave happens at the boundary between air and rock—the surface of the earth.

Hope this helped you!

God bless ;)

Select the correct answer. In which state of matter do molecules have the lowest kinetic energy? A. liquid state B. plasma state
Svetllana [295]

Answer:

D. Solid state

Explanation:

In solid state the particles of  a substance, vibrate in fixed positions though they posses less kinetic energy. This is the reason as to why the particles do not move far apart from each other making the solids remain in fixed shapes unless an extra energy is added.

What is the Dependent variable?
horsena [70]

Explanation:

Just like an independent variable, a dependent variable is exactly what it sounds like. It is something that depends on other factors. For example, a test score could be a dependent variable because it could change depending on several factors such as how much you studied, how much sleep you got the night before you took the test, or even how hungry you were when you took it. Usually when you are looking for a relationship between two things you are trying to find out what makes the dependent variable change the way it does.

Draw the lewis structure for butanal, which has the condensed formula ch3(ch2)2cho. show all hydrogen atoms and lone pairs of el
sergejj [24]

There are 10 hydrogen atoms that bind and there are 2 pairs of free electrons in the non-binding O atom

<h3>Further explanation</h3>

Aldehydes are alkane-derived compounds containing carbonyl groups (-CO-) where one bond binds to an alkyl group while another binds to a hydrogen atom.

The general structure is R-CHO with the molecular formula :

\large{\boxed{\boxed{\bold{C_nH_{2n}O}}}

Naming is generally the same as the alkane by replacing the suffix with -al

Butanal or butyraldehyde is an aldehyde which has 4 C atoms

Inside the structure there are 3 atoms involved in bonding:

  • 1. Atom C with 4 valence electrons, requires 4 electrons to reach the octet
  • 2. Atom O with 6 valence electrons, requires 2 electrons to reach the octet
  • 3. Atom H with 1 valence electron, requires 1 electron to reach a duplet

In describing Lewis's structure the steps that can be taken are:

  •  1. Count the number of valence electrons from atoms in a molecule
  • 2. Give each bond a pair of electrons
  • 3. The remaining electrons are given to the atomic terminal so that an octet is reached
  • 4. The remaining electrons that still exist in the central atom
  • 5. If the central atom is not yet octet, free electrons are drawn to the central atom to form double bonds

In the Butanal structure (C₄H₈O) there is 1 double bond of the functional group (-CHO) between the C atom and the O atom
