Two solutions are added together and the new solution becomes hot. This tells you that

3. Infer A forgotten ice pop lies melting on a deck on a hot summer day. What is the direction of heat flow as the ice pop melts

Ira Lisetskai [31]

Answer:

Endothermic. The energy is flowing into the molecules causing them to break apart and the ice pop change state.

The correct IUPAC name for the following molecule is: _________

andrew-mc [135]

Answer:

A.) trans-2,3-dichloro-5-methyl-2-hexene

Explanation:

The proposed question and structure has been attached to this answer.

The cis- and trans- isomers are used to denote the alignment of the functional groups to the carbon chain side. From the diagram, we see that:

the two chloro groups on the main compound are in opposite directions (-trans), and not the same sides (-cis)
The bottom extended methyl group is on the 5th carbon as we count from left to right
there's a total of 6 carbon atoms with 1 double bond on the second to third carbon.

Hence the name trans-2,3-dichloro-5-methyl-2-hexene

What color has a wavelength of 6.49*10^23?

Yakvenalex [24]

Wavelength of any wave can't be equal to the number with exponential of 23, otherwise, if you're focusing on visible light, and neglecting the exponential then your color would be: orange. [ Again, remember wavelengths can be in between 10 to 10^-14 ]

In short, Your Answer would be: Orange

Hope this helps!

Predict the carboxylic acid product of the following reaction:CH3COOCH2CH3ethyl ethanoate+H2OH+⟶carboxylic acid+CH3CH2OHethanolE

GaryK [48]

Answer: The IUPAC name of the carboxylic acid formed is ethanoic acid.

Explanation:

The basic rules for naming of organic compounds are :

First select the longest possible carbon chain.
The longest possible carbon chain should include the carbons of double or triple bonds.
The naming of alkane is done by adding the suffix -ane, alkene by adding the suffix -ene, alkyne by adding the suffix -yne and carboxylic acid by adding the suffix -oic acid.
The numbering is done in such a way that first carbon of double or triple bond gets the lowest number.
The carbon atoms of the double or triple bond get the preference over the other substituents present in the parent chain.

For the given chemical reaction, the equation follows:

$CH_3COOCH_2CH_3+H_2O\rightarrow CH_3COOH+CH_3CH_2OH$

When hydrolysis of ester takes place, it leads to the formation of an alcohol and a carboxylic acid.

So, when hydrolysis of ethyl ethanoate occurs, it produces ethanol and a 2- Carbon carboxylic acid named as ethanoic acid.

Hence, the IUPAC name of the carboxylic acid formed is ethanoic acid.

A student analyzes soil samples from her backyard. She organizes the samples into three categories, based on their pH. The three

Bogdan [553]

Answer: circle graph.

Justification:

A circle graph (also known as pie chart) is excellent to visualize the relative size of different sectors. Being the entire circle 100%, each sector will show the percent of each category.

In the given example, the circle will be divided in 3 different sectors, in which the size is proportional to the percent of each one.

In the given case::

pH less than 8: 20%

 pH between 8 and 8.5: 50%,

pH greater than 8.5: 30%


So, a sector whose area is 20% will represent the first category, a sector whose area is 50% will represent the second category, and a sector whose area is 30% will represent the third category. The whole circle is 100%, this is the sum of the 3 categories is 100%.
