Is salad dressing a homogeneous mixture ?

Cis 2,3 dibromo 2 hexene

Answer :

Heterogeneous because it isn’t evenly mixed…you could take two samples from two different parts of it and they would have different compositions.

Definitely heterogeneous – it has lots of different stuff in it. If it were homogeneous matter, you might expect it to be a smooth mixture. Most salad dressing, however, uses oil and vinegar, which do not mix, which is why you usually shake salad dressing before pouring it. There are probably some salad dressings that could be considered homogeneous, but the answer called for by the question is “heterogeneous”.

26 long painting is how many yards long ?

A 26′ long painting is how many yards long?

A. 2 1/6 yards

B. 8 2/3 yards

C. 23 yards

D. 73 yards

Answer :

8.7 yards is approximately 26 feet long [ 26′ divided by 3 feet per yard]

Since the greatest accuracy is two digits, the greatest accuracy of the answer cannot be 8.66666…

To two significant digits, the answer is 8.7 yards.

26/3 = 8.67 yards

26 divided by 3 equals 8 2/3 yards.

Dinitrogen trioxide ionic or covalent ?

Answer :

The answer is covalent. Dinitrogen trioxide is covalently bonded.

It contains covalent bonds since it consists entirely of nonmetal atoms

You can tell just by the name that it has covalent bonds. When you see those prefixes (mono-, di-, tri-, tetra-, penta-, hexa-, etc.) in the name, you know that it is covalent. Plus, nitrogen and oxygen are both nonmetals, so it has to be covalent. Ionic bonds are between metals and non-metals, or polyatomic cations and anions such as NaCl, MgCO3 and NH4NO3.

What change resulted in the building of european megaliths ?

Name the contributions of the early pioneers in microbiology ?

Answer :

Antonie van Leeuwenhoek, Athanasius Kircher, and Robert Hooke were the first people to view microbes using some of the first self-built microscopes.

Ferdinand Cohn, Louis Pasteur, and Robert Koch were pioneers in bacteriology, the discovery and understanding of the subset of microbes that are bacteria. This had a direct and immediate impact on food storage and disease causality.

Martinus Beijerinck and Sergei Winogradsky are credited with the discovery of general microbiology, which laid the ground work for our understanding of microbial physiology, diversity, and ecology.

Joseph Lister: By applying Louis Pasteur’s advances in microbiology, he promoted the idea of sterile portable ports while working at the Glasgow Royal Infirmary. Lister successfully introduced carbolic acid (now known as phenol) to sterilise surgical instruments and to clean wounds, which led to a reduction in post-operative infections and made surgery safer for patients.

Lethargic vital trite is to ?

Answer :

“Lethargic” is to “vital” as “trite”

“Lethargic” is to “vital” as “trite” is to “original.” “Lethargic” means lazy, whereas “vital” means full of life. “Trite” means copycat, and the opposite of “copycat” is “original.” “Trite” can also mean cliché, tired or overplayed.

Lethargic means “sluggish”, kind of inactive. Vital means full of energy, lively. So, they are antonyms.

How did the microchip change computers during the 1990s ?

Answer :

The same way they changed computers in the 1960s when they were first introduced: computers got smaller, faster, less expensive, used less power, they could now be used in more places, by a wider variety of people, and for a wider range of applications. The same thing will continue well into the foreseeable future. microchips were introduced in the 1960s microprocessor chips were introduced in the 1970s improved microprocessor chips were introduced in the 1980s, permitting business PCs and simple game computers for the home improved microprocessor chips were introduced in the 1990s, permitting powerful business PCs and practical home PCs specialized graphics microprocessors and multi-core microprocessors were introduced after 2000, permitting offloading of highly compute intensive operations from the main CPU and permitting true multiprocessing in small affordable machines, effectively providing supercomputer like performance to the average everyday user. etc.

James Madison’s Contribution to the Constitution

When James Madison and the other 56 delegates to the Constitutional Convention met in Philadelphia in May 1787, they intended to amend the Articles of Confederation. They ended up creating a new constitution, and Madison, representing Virginia, became the chief recorder of information (he took a lot of notes).

Madison had helped develop Virginia’s Constitution 11 years earlier, and it was his “Virginia Plan” that served as the basis for debate in the development of the U.S. Constitution. Madison argued strongly for a strong central government that would unify the country. The Convention delegates met secretly through the summer and finally signed the proposed U.S. Constitution on September 17, 1787. Did this mean that the Constitution automatically became the law of the land?

In order for the Constitution to become the law by which all Americans abided, two-thirds of the 13 states had to ratify (approve) it individually, and it was sent to them for this purpose on September 28. Madison campaigned for the ratification of the Constitution by co-authoring a series of essays with John Jay and Alexander Hamilton that appeared in various New York newspapers and then circulated around the states. There were 85 essays in all (Madison wrote 29), and they were known as the Federalist Papers.

Madison’s important contribution to the overall creation of the Constitution earned him the nickname “Father of the Constitution” later in life. On June 21, 1788, New Hampshire became the ninth state to ratify the new Constitution, and that was enough to make the Constitution the law of the land. But that wasn’t all. … Madison went on to strengthen the Constitution even further. Do you know how?

In 1789, as a member of the newly created U.S. House of Representatives, James Madison introduced the first amendments (additions) to the Constitution, which are now known as the Bill of Rights. Ratification of the Constitution by some states was based on the expectation that the Constitution would be changed by amendments such as these. Madison originally drafted 19 amendments, 12 of which his congressional colleagues passed on to the states for their approval. On December 15, 1791, 10 had been ratified by enough states to become part of the Constitution.

These amendments guarantee our individual rights as citizens, such as the freedom of speech, religion and the press (in the First Amendment). Seen here is a copy of Madison’s notes for his speech introducing the Bill of Rights on the floor of the House of Representatives. In 1785, Madison had written one of the most significant essays regarding separation of religion and government (often referred to as the separation of church and state), which no doubt gave him inspiration for some of the Bill of Rights.

James Madison

Born: March 16, 1751 (March 5, Old Style), in Port Conway, Virginia

Died: June 28, 1836, in Montpelier, Virginia

James Madison, the fourth president of the United States (1809-1817), is recognized as the “Father of the Constitution.” He helped craft the original document and co-wrote the Federalist Papers, which helped get the Constitution approved by the states. We also have him to thank for the Bill of Rights, the Constitution’s first 10 amendments, which guarantee our freedoms to this day. Madison was a shy man who married the very outgoing Dolley Payne Todd. During the War of 1812, first lady Dolley Madison saved many White House artifacts and her husband narrowly escaped death when the British burned Washington.

Is ch4 ionic or covalent ?

Answer :

Covalent – the Share of electrons between 2 or more non-metals

Ionic – the Exchange of electrons between a non-metal and a metal

CH4 is Covalent since both elements are non-metals.

CH4 , methane is totally covalent with 4 sp3 bonds arranged in a tetrahedron.The C-H bonds exhibit NO polarity as the electronegativities of the two atoms are nearly identica. CH4 has NO ionic character.

The C-H bond is very mildly polar covalent, but the symmetrical tetrahedral shape of the molecule does not allow unequal sharing of bonded electrons. Thus methane is a covalent molecule.
