A fish is swimming at a constant rate towards the ocean floor. The equation

1 answer:

7 0

A ﬁsh is swimming at a constant rate toward the ocean ﬂoor. The equation y = −7x − 3 can be used to represent this situation, where y is the depth of the ﬁsh in meters below sea level and x is the number of seconds the ﬁsh has been swimming. Which statement best describes the depth of the ﬁsh, given this equation?
From a starting position of 7 meters below sea level, the ﬁsh is descending 3 meters per second.
B From a starting position of 7 meters below sea level, the ﬁsh is ascending 3 meters per second.
C From a starting position of 3 meters below sea level, the ﬁsh is descending 7 meters per second

Explain how natural resources are identified and why natural recourses are in evenly distributed.

mixer [17]

Answer:

Natural resources are not evenly distributed all over the world. Some places are more endowed that others — for instance, some regions have lots of water (and access to ocean and seas). Others have lots of minerals and forestlands. Others have metallic rocks, wildlife, fossil fuels and so on.

Activation energy is what kind of chemical reaction that absorbs energy

seraphim [82]

Activation energy is the energy required by reactants to undergo chemical reaction and given products

Every reactant has some internal energy (sum of all kind of energy like kinetic energy, potential energy, mechanical energy, chemical energy etc). It needs some extra energy to undergo chemical reaction which is activation energy

All kinds of reaction whether exothermic or endothermic needs activation energy

Threshold energy = internal energy + activation energy

Determine the mass of CO2 formed if 15 grams of C4H10

Svetlanka [38]

Answer:

$m_{CO_2}=45gCO_2$

Explanation:

Hello there!

In this case, since the combustion of butane is:

$C_4H_{10}+\frac{13}{2} O_2\rightarrow 4CO_2+5H_2O$

Thus, since the molar mass of butane is 58.12 g/mol and that of carbon dioxide is 44.01 g/mol, we obtain the following mass of CO2 product:

$m_{CO_2}=15gC_4H_{10}*\frac{1molC_4H_{10}}{58.12gC_4H_{10}} *\frac{4molCO_2}{1molC_4H_{10}} *\frac{44.01gCO_2}{1molCO_2} \\\\m_{CO_2}=45gCO_2$

Best regards!

If you had used toluene instead of methyl benzoate in this reaction, what nitration product(s) would have formed? Write a stepwi

PilotLPTM [1.2K]

Answer:

See explanation

Explanation:

The electrophilic substitution of aromatic compounds occurs faster in substituted aromatic compounds due to the fact that the ring becomes more or less susceptible to electrophilic attack depending on the nature of the substituent in the ring.

Electron pushing substituents such as alkyl groups stabilize the positive charge developed during electrophilic substitution hence they activate the ring towards electrophilic substitution.

The methyl group is an ortho - para directing substituent hence the product obtained by nitration of toluene is o-nitrotoluene and p-nitrotoluene.

The stepwise mechanism for obtaining these products is shown in the image attached to this answer.
