How does a molecular compound compare to the elements that make up the compound?
a
the properties of a compound depend on the identity of the component elements, and not the chemical bonds they fom.
b
the properties of a compound depend on the size of the molecule, and not the component elements
c. the properties of a compound are generally similar to the properties of the elements that make it up
d. the properties of a compound are usually very different from the properties of the elements that make it up

D

Explanation:

The individual properties of the atoms of a compound do not matter anymore because the combined effect of their interactions results completely different properties. The types of bonds formed and the ratio of the elements in the compound, for example, have a huge effect on the properties of the compound. An example is water that is liquid at room temperature while its constitute atoms (those of Hydrogen and Oxygen) are gaseous at room temperature.

D. The properties of a compound are usually very different from the properties of the elements that make it up

Explanation - Compounds are those substances that are made elements that are combined in a fixed proportion or ratio. If all the elements constituting a compound is same then it is a homogenous compound and even if a single element is different, then it is called as heterozygous compound.

Vapor pressure, boiling point and density are the physical properties of compounds. Compounds also have chemical properties which is visible during a chemical reaction. The elements when combine to form a compound then its individual property is lost.

why many students visually perceive stem as a vapid class?

for many students, however, stem subjects are optically discerned as vapid, tedious, and destitute of authentic-world applications. science and math have always been a major part of the high school curriculum, but many students have disengaged from these subjects because they don’t optically discern that they have any pertinence to the authentic world or students’ daily lives. for them, math and science have become a set of rules, procedures, laws, theorems, and formulas to memorize. some students even develop math apprehensiveness and cerebrate they are incapable of learning higher-level mathematics.

why is stem paramount?

as the u.s. economy changes, the ordinant dictation for stem-capable workers is growing. in may of 2014, the u.s. bureau of labor statistics counted more than 8.3 million stem jobs, which accounted for 6.2 percent of total employment in the cumulated states. that number is expected to perpetuate to increment as u.s. companies grow and innovate to compete in the ecumenical economy. according to the u.s. department of labor, the average salary for all stem jobs is $85,570, which is virtually double the average salary for all jobs.

many people still envision stem professionals as wearing a white lab coat and conducting research in a laboratory. in authenticity, some of the most in-demand stem fields are petroleum engineering, process engineering, and computer engineering. these fields that are experiencing shortages of qualified candidates are additionally among the highest paying, with the average petroleum engineer earning an annual salary of $147,520 in may 2014 according to the u.s. bureau of labor statistics.

in additament, stem subjects edify students valuable skills that are vital for prosperity in all vocations, even those that do not directly require stem erudition. engagement in stem subjects avails students develop quandary-solving, critical mentally conceiving, and leadership skills. these skills are so ecumenical, in fact, that statistics relinquished in the summer of 2013 by the u.s. census bureau designated that about three-quarters of the people with a bachelor’s degree in stem fields are not working in those vocations. many non-stem employers are poaching stem-qualified job candidates because they are more ingenious and collaborative than their non-stem counterparts.

as the ecumenical economy perpetuates to evolve, the desideratum for stem-capable workers will perpetuate to grow. by getting edifiers and students involved in the stem kineticism, an incipient generation of adroit workers will be poised to energize and expand this exhilarating field.
