I don't know what model you're referring to so I can't answer the question. However, upon researching, I found a similar problem. I posted it as an attached picture. Looking at the model, the amount of grams a herbivore eat each day corresponds to the arrow pointing inwards. Since the label says 4.0 g,
<em>the answer is 4 g per day</em>.
Answer:
D. all of these
Explanation:
In the classification of organisms, they are placed into groups which they appropriately fit into.
All the choices given correctly shows the process of classifying organisms. This aspect of biology is described as taxonomy.
- Based on characteristics of organisms, they are put into the same groups
- Also, we can identify the related family and genus in which a discovered organism can be put into.
- They phylogenetic relationship between organisms are important for classification.
Explanation:
first find the the number of moles of of zinc .
as the number of moles of zinc and ZnCl2 is same we can calculate the mass of ZnCl2.
860 mL.
<h3>Explanation</h3>
Separate this process into two steps:
- Cool the balloon from 305 K to 265 K.
- Reduce the pressure on the balloon from 0.45 atm to 0.25 atm.
What would be the volume of the balloon after each step?
After Cooling the balloon at constant pressure:
By Charles's Law, the volume of a gas is directly related to its temperature in degrees Kelvins.
In other words,
,
where
and 
are volumes of the same gas.
and 
are the temperatures (in degrees Kelvins) of that gas.
Rearranging,
.
The balloon ended up with a lower temperature. As a result, its volume drops: 
.
After reducing the pressure on the balloon at constant temperature:
By Boyle's Law, the volume of a gas is inversely proportional to the pressure on this gas.
In other words,
,
where
- and are volumes of the same gas.
and 
are the pressures on this gas.
Rearranging,
.
There's now less pressure on the balloon. As a result, the balloon will gain in volume: 
.
The final volume of the balloon will be 
.
