You've asked your friends to define the terms "chemistry" and "chemical." With which definitions do you agree? Check all that ap

ply. Check all that apply. A chemical is a substance that has the same composition but different properties wherever it is found. Chemistry is the study of the composition, structure, properties, and reactions of matter. Chemistry is a natural science concerned with the study of life and living organisms, including their structure, function, growth, evolution, distribution, and taxonomy. A chemical is a substance that has the same properties but different composition wherever it is found.

Answer:

  • A chemical is a substance that has the same composition and properties wherever it is found
  • Chemistry is the study of the composition, structure, properties, and reactions of matter

Explanation:

A chemical is made up of one or more chemical compounds that allow it to fulfill a particular function, because a chemical is a substance that has the same composition and properties wherever it is found.

Already Chemistry is a branch of the Natural Sciences that studies the matter, its properties, constitution, transformations and the energy involved in these processes. Matter, and all that composes it, is the main object of study of chemistry.

What geometry does VSEPR predict for the central atom in NCl3
Archy [21]

Answer:

Tetrahedral electron geometry and trigonal pyramidal molecular geometry.

Explanation:

The Lewis structure is shown in Figure 1.

The central N atom has three bonding pairs and one lone pair, for <em>four electron groups</em>.

VSEPR theory predicts a tetrahedral electron geometry with bond angles of 109.5°.

We do not count the lone pair in determining the molecular shape.

The molecular geometry is trigonal pyramidal (see Figure 2).

trasher [3.6K]

Answer:

They will create an ionic bond.

Explanation:

The atom with the one valence electron will lose its one, because it's a metal and metals will lose electrons to become stable. The nonmetal (with 7 valence electrons) will gain that electron, therefore creating a stable octet for the nonmetal, making the compound stable.

State one type of additional information that could be used to determine if these three species are closely related.
Luda [366]

Answer:

Study the bone structure of limbs.

Explanation:

Study the bone structure of limbs can be used to find out the relatedness and relationship among three species because the pattern of bones structure is similar but the structure is different from one another due to different environmental conditions. This study provides important and useful information whether the three species are closely related or not. If they have similar bone structure than we can say that there are more chances that they are closely related to each other.
