Answer:
The samphor
Explanation:
The samphor is a double headed barrel drum which is used in Cambodia as a musical instrument.
It has uneven drum heads, with one side bigger than the other and both can be played simultaneously or at the same time.
These attackers sought to create political pressure within France to suspend airstrikes against ISIS targets within Syria.
<h3>What is
terrorism?</h3>
Terrorism can be defined as an unlawful use of both force and violence against the people living in a geographical location, so as to intimidate or coerce them and their government in furtherance of political, cultural or social objectives and interests.
In 2015, ISIS attackers targeted six (6) different locations throughout Paris, so as to create political pressure within France for the suspension of airstrikes against Islamic State of Iraq (ISIS) targets within Syria.

Around 1700, a sequence of events led to today's highly globalized economy and unequal global wealth distribution. The sequence is as follows:
- Virtually the entire world lives at a subsistence level.
- Dramatic increase in food production in Europe due technological advances in farming lead.
- Factory production replaces European cottage industries.
- Western colonialism at its peak transfers wealth from the colonies to Europe.
- Former colonies of Europe struggle economically post independence
The economy in 1700s was based on mainly farming, fur trading, ship production, local production.

Answer:One factor that enabled the Renaissance to flourish in Northern Italy was that the region had a wealthy class that invested in the arts. During this period, there were many rich families that heavily invested and supported artworks and their artists. One of the most prominent families at the time was the Medici family who were benefactors of artists like Michelangelo and Botticelli.
Explanation:
Answer: arrange a number of given straight-chain alkanes in order of increasing or decreasing boiling point or melting point.
arrange a series of isomeric alkanes in order of increasing or decreasing boiling point.
explain the difference in boiling points between a given number of alkanes.
Explanation:Table 3.5.1 describes some of the properties of some straight-chain alkanes.
There is not a significant electronegativity difference between carbon and hydrogen, thus, there is not any significant bond polarity. The molecules themselves also have very little polarity. A totally symmetrical molecule like methane is completely non-polar, meaning that the only attractions between one molecule and its neighbors will be Van der Waals dispersion forces. These forces will be very small for a molecule like methane but will increase as the molecules get bigger. Therefore, the boiling points of the alkanes increase with molecular size.
For isomers, the more branched the chain, the lower the boiling point tends to be. Van der Waals dispersion forces are smaller for shorter molecules and only operate over very short distances between one molecule and its neighbors. It is more difficult for short, fat molecules (with lots of branching) to lie as close together as long, thin molecules.
The boiling points shown are for the "straight chain" isomers of which there is more than one. The first four alkanes are gases at room temperature, and solids do not begin to appear until about C17H36 , but this is imprecise because different isomers typically have different melting and boiling points.
