Answer:
if a foreign lion species is introduced into the ecosystem then it can affect the ecosystem in anyway...
Explanation:
because there are chances that the lion might substitute the other predators present in that region.there are chances that the ecosystem may maintain the equillibrium.

How does fog rising off water compare to plant growth?
The humidity in the air affects the evapotranspiration rate from the leaf surfaces. ... The use of fog and mist at this time can reduce the air temperature and increase the humidity within the plant canopy without saturating the plant medium. With more oxygen in the root zone, faster rooting occurs.

What is the approximate value of the equilibrium constant K P for the change C 2 H 5 OC 2 H 5 ( l ) ⇌ C 2 H 5 OC 2 H 5 ( g ) at 25 ° C. (The equilibrium vapor pressure for this substance is 570 torr at 25 ° C.) 760 torr = 1 atm R = 0.0821 L * atm / (mol * K)
Answer:
Kp for this equilibrium ≅ 570
Explanation:
This is a situation where we have an heterogeneous mixture.
We get gas from liquid state:
C₂H₅OC₂H₅ (l) ⇌ C₂H₅OC₂H₅ (g)
In order to determine Kc → [C₂H₅OC₂H₅ (g)], in equilibrium
Liquid or solid do not count for Kc, neither Kp
Kp → Partial pressure of C₂H₅OC₂H₅ (g)
Kc or Kp at equilibrium do not depend on the amount of liquid, there is; although it cannot be null since otherwise there would be no reaction.
Kp for this equilibrium ≅ 570
(Value for partial pressure in the only gas).
In order to determine Kc we can replace data at this formula
Kp = Kc (R . T)^ ⁽ⁿ ⁻ ⁿ°⁾
Where n - n° is the difference between the moles of produced gas. We only have 1 mol.
Kp = Kc (298K . 0.082)¹
570 Torr / (298K . 0.082) → Kc

What is the manipulated variable, responding variable, and controlled Variable
observe different electrolytes in a wet cell that will light a
bulb most brightly.
Answer:
Manipulated/independent variable- DIFFERENT ELECTROLYTES
Responding/dependent variable- BRIGHTNESS OF BULB
Controlled variable- WET CELL
Explanation:
The independent variable, also known as manipulated variable is the variable that the experimenter changes or manipulates in an experiment. In this case where different electrolytes are observed to see which will light a bulb most brightly, the manipulated variable is the DIFFERENT ELECTROLYTES.
Dependent or responding variable is the variable of an experiment that responds to the changes made to the independent variable. It is the variable that is being measured in an experiment. In this case, the BRIGHTNESS OF BULB is dependent on the electrolyte used, hence, it is the responding variable.
Controlled variable or constant is the variable that the experimenter keeps the same throughout the experiment. In this case, the WET CELL is kept constant for all the electrolytes used i.e. it is not changed, hence, the WET CELL is the controlled variable.
In the tropical rainforests, birds have evolved to eat the brightly-colored fruits. The fruits have evolved their attractive color so the birds will eat them and spread their seed. What theory is this an example of? A artificial selection b coevolution c mutation d natural selection
Answer:
coevolution
Explanation:
Coevolution plays a key role in shaping the biodiversity on Earth. Coevolution is commonly defined as reciprocal evolutionary changes brought about by interactions between species, implying that interacting species impose selection on each other(Science direct).
We can see that the change that occurred in the plants of the tropical rainforests is closely related to their link to birds. The fruits evolved an attractive color so that birds, having evolved to eat the brightly-colored fruits, may eat them.
HELP PLZ ITS DUE IN 10 MIN "Jack's model includes one object consisting of two molecules and one object consisting of six molecules. He put 16 energy cubes in each object and stated that his model showed the two objects at equilibrium. Explain what is wrong with Jack's model."
(I know it looks long but basically I just need help with finding what's wrong with the model)
Answer: the molecules have different energy and the system is not in equilibrium
Explanation:
The model developed by Jack has the same energy for each of the two objects, but as each object is made up of a different number of molecules, in the system with more molecules, object 2, each one has approximately 2.4 less energy and the molecules of Object 1 have an E / 2 energy.
So when you book them together the molecules have different energy and the system is not in equilibrium
Jack presented the model as if the two objects were in energy balance, but this is not possible, as each object has a different number of molecules.
We can arrive at this answer because:
For the system presented in Jack's model to be in energetic balance, it would be necessary for the two objects present in the model to have the same number of molecules.This is because, with equal amounts of molecules, each object would be able to emit the same amount of energy.However, the object with fewer molecules tends to emit less energy than the object with more molecules.This allows for an uneven, unbalanced emission of energy in the system and this unevenness is not presented in Jack's model.

How many elements are in (NH4)3PO4
Answer:
4
Explanation:
There are 4 different elements in the compound (N, H, P, O) but if you want to count the number of each element then the answer is different.
In NH4, theres 1 N and 4 H, but since there are 3 NH4s then u have 3 N and 12 H. There's 1 P and 4 Os as well.
Added together u have 3 + 12 + 1 + 4 = 20 elements in total.

Why do engineers use metals in making
electrical wires
Answer:
Why is copper used for most electrical wiring? All metals have some amount of resistivity to electrical currents, which is why they require a power source to push the current through. The lower the level of resistivity, the more electrical conductivity a metal has
What is the correct hybridization for a ion of IF6 that has a charge of (1-)
Answer:
6 F atoms at 6 corners
Explanation:
The shape of IF6 (-1) is trigonally distorted octahedron. The central iodine atom has 7 valence electrons. It gains one electron from negative charge. Out of 8 electrons, 6 are imvolved in formation of 6 I - F bonds and one lone pair of electrons is present. 6F atoms are present at 6corners of distorted octahedron. The lone pair of electrons distorts the octahedral shape due to electron repulsion.
