Model A is better than Model B as Model A shows the three-dimensional shape of the molecule, but Model B does not. The correct option is c.
What are molecules?The smallest particle of a substance possesses all of its physical and chemical properties. One or more atoms make up a molecule.
Knowing the molecular weights of the molecules allows us to calculate their sizes. The molecular weight of a molecule is the sum of the atomic weights of the atoms in the molecule.
The relative atomic mass of particles determines their size. Particles with a higher relative atomic mass weigh more than particles with a lower relative atomic mass. Larger atoms have heavier iotas and a larger relative atomic mass.
Therefore, the correct option is c, Model A shows the three-dimensional shape of the molecule, but Model B does not.

WHAT DOES THE MASS OF AN OBJECT MEASURE HURRYYYYYYYYYYYYYYYYYYYYY
Answer:
object's inertial property
Explanation:
The mass of an object is a measure of the object's inertial property, or the amount of matter it contains. The weight of an object is a measure of the force exerted on the object by gravity, or the force needed to support it. The pull of gravity on the earth gives an object a downward acceleration of about 9.8 m/s2.

What is the hybridization of the carbon in the HCN molecule?
how does an electron emit light?
Answer:
by moving between defined energy levels
You are sitting in the central park bleachers of a Major League baseball park. You see a batter strike a pitched ball. About 0.4 seconds later you hear the contact between the bat and the ball. In terms of the properties of light and sound waves, how do you explain the difference in the communications you receivedbabout the same event?
Answer:
See the answer below
Explanation:
The speed of light in air and space is faster than the speed of sound in the same media. Light travels with a speed of approximately 3 x [tex]10^8[/tex] m/s while sound can only travel at 343 m/s (at 20 [tex]^oC[/tex]).
Consequently, the visuals of a batter striking a pitched ball which travel by light and is perceived through the eyes would be seen before the sound of the strike.
The difference in the speeds of light and that of sound largely explains the difference in the communication received about seeing a batter striking a pitched ball before hearing the sound of the strike

which information does the chemical formula co2 not give you?
A. number of valence electrons in each atom
B. ratio of atoms in the compound
C. total number of atoms in one molecule of the compound
D. type of elements in the compound
Answer:
A
Explanation:
Considering the definition of chemical formula, the correct answer is option A): number of valence electrons in each atom.
A chemical formula is the representation of the elements that make up a compound and the proportion in which they are found, or the number of atoms that make up a molecule.
In other words, a chemical formula is an alphanumeric expression that is used to indicate the composition of a chemical substance and that is constructed from the symbols of its constituent elements, affected by numerical subscripts that report the number of atoms of each element that it is part of the substance.
In summary, the correct answer is option A): number of valence electrons in each atom.

is bird seed homogeneous or heterogeneous
Answer:
heterogeneous
In order to give birds a varied and balanced diet, commercial bird seed blends typically include a range of seeds, grains, and other substances. As a result, bird seed is frequently categorised as a heterogeneous blend.
A seed is referred to as homogenous if its genetic makeup, size, shape, and other traits are all consistent. To guarantee consistency in the ensuing plants, these seeds are typically created through controlled breeding or genetic manipulation. A heterogeneous seed, on the other hand, is one that varies in genetic makeup, size, shape, and attributes. These seeds frequently result from cross-pollination or natural pollination between various species or kinds.

Why is sublimation such a critical component for the water cycle in cold climates?
Answer:
Sublimation is the transition in physical state from solid (ice) to vapor with no intermediate liquid stage. In other words, the ice becomes water vapor without melting. Ideal weather conditions would be low humidity (to allow vaporization), high altitude (lower air pressure facilitates the transition), and strong sunlight (to provide the energy for the transition). High snow-packed mountain ranges offer all of these conditions. Since the temperature is too cold for evaporation, sublimation is needed to provide enough water vapor to feed the water cycle and promote precipitation elsewhere on the planet. Without it, the water would stay frozen in the snow and ice and reduce the amount of liquid water that would replenish the planet.
