noname [10]

Answer:

Option B:Publishing scientific journals

Explanation:

We are told that Lindsey is trying to gain credibility for her studies.

Since she completed her experiment and discussed her finding with colleagues, the most logical next step would be to publish scientific journals. This is because the other options given are not steps that should be taken because she has completed the research and therefore has no need to speak at a conference next nor even create new charts which they must have done during the research. No need for her to make sure the topic is popular.

Option B is correct

Which path will a carbon atom most likely travel from CO2 in the atmosphere to glucose in the cell of a secondary consumer
SVETLANKA909090 [29]

Answer:

See the answer below

Explanation:

<em>The carbon will have to travel in the form of CO2 from the atmosphere to a primary producer (green plant), from there to a primary consumer (herbivorous animal), and finally to a secondary consumer.</em>

The primary producer (a green plant) would fix the carbon in the CO2 to carbohydrate through a process known as photosynthesis. The equation of the process is as shown below:

6 CO_2 + 6 H_2O --> C_6H_1_2O_6 + 6 O_2

The carbon, now in the form of carbohydrate, would then be picked up by an animal (a primary consumer) that feeds on the green plant. The carbon would eventually get into a secondary consumer when the secondary consumer feeds on the primary consumer that fed on the green plant.

Malic acid, C4H6O5, has been isolated from apples. Because this compound reacts with 2 molar equivalents of base, it is a dicarb
Flura [38]

Answer and explanation:

The attached figure shows five different structures for the chemical formula C4H5O5, but only one of these structures represent the malic acid.

Malic acid is a dicarboxylic acid, this means malic acid has two

-COOH groups.  Also, malic acid is a secundary alcohol, which means it has a  R2-C-OH group.

-Structure A has two carboxylic groups, but it doesn´t have a secundary alcohol.

-Structure B doesn´t have any caborxylic group.

-Structure C has two carboxylic groups and  it is a secundary alcohol. Structure C is the Malic acid

2C3H7OH + 9O2 -&gt; 6CO2 + 8H2O
MAVERICK [17]

Answer:

Up to 18\; \rm mol \rm CO_2.

Explanation:

The equation for this reaction: 2\; \rm C_3 H_7 OH + 9\; O_2 \to 6\; CO_2 + 8\; H_2O is indeed balanced.

Notice that the coefficient of \rm C_3 H_7 OH is 2 while that of \rm CO_2 is 6.

Therefore, each unit of this reaction would consume 2 units of \rm C_3H_7OH while producing 6 units of \rm CO_2. In other words, this reaction would produce three times as much \rm CO_2\! as it consumes \rm C_3H_7OH\!.

If all that 6\; \rm mol of \rm C_3H_7OH molecules are actually consumed through this reaction, three times as many \rm CO_2 molecules would be produced. That corresponds to 3 \times 6\; \rm mol = 18\; \rm mol of \rm CO_2\! molecules.
