The answer is TRUE. Competition is rivalry between individuals for a particular resource
Competition amongst individuals?
Competition can be described as an interaction between two individuals in which they both fight for the available resources in the environment.
For example, when there is limited source of food and water in an environment, the individuals or organisms present will struggle to take the available food in order to survive while those individuals that were unable to get this resource might end up dead as the available food is limited.
This also occurs in plants and they also compete for sunlight, food, water.

A solution is prepared by dissolving 8.50 g of c6h12o6 in 4.15 g of cyclohexane. what is the % mass of c6h12o6 in the new solution? round your answer to 1 decimal places.
Answers
The % mass of C6H12O6 in the new solution is approximately 67.2%.
We can calculate the mass percentage of C6H12O6 in the new solution using the following formula:
% mass = (mass of C6H12O6 / total mass of solution) x 100%
First, we need to calculate the total mass of the solution by adding the mass of C6H12O6 and the mass of cyclohexane:
total mass of solution = 8.50 g + 4.15 g = 12.65 g
Next, we can calculate the mass percentage of C6H12O6 in the solution:
% mass = (8.50 g / 12.65 g) x 100% ≈ 67.2%
Therefore, the % mass of C6H12O6 in the new solution is approximately 67.2%.

Answers
The value for the radius of the ammonium ion is 167 pm.
What is atomic radius?Atomic radius is half the distance between adjacent atoms of the same element in a molecule. measuring the atomic radii of chemical elements is a difficult task because the atomic size is in the order of 1.2×10-10 m. The electron cloud forming the atomic shell does not have a specific shape, which makes it difficult to determine the size of the atom. So we can say that we cannot practically determine the size of an individual atom.
The radius of an atom increases in proportion to its atomic number. The radius of each nearest neighbour atom increases as you proceed down a certain column of the periodic table. As you move down the periodic table, the number of complete electron shells increases, resulting in a larger size.
since,
cations and anions are in contact across the body diagonal of the unit cell
so, unit cell is type body centre
4x(radius) = 1.73x(edge length)
4x(radius) = 1.73x386
4x(radius) = 667.8
(radius) = 167 pm

In the last activity, you figured out that the evaporator and the condenser both worked by transferring thermal energy from one substance to another. However, you also noticed that the compressor did not function that way since it was not designed to transfer thermal energy to or from the refrigerant. However, you did notice that the compressor increased the pressure of the refrigerant. Could this increase in pressure be related to the increase in temperature?
Answers
Answer:
Yes, the increase in pressure of the refrigerant can be related to the increase in temperature. This is because when a gas is compressed, the molecules are forced closer together, which increases the temperature of the gas. This is known as the ideal gas law, which states that when pressure increases, temperature also increases.

Answer:
0.0123 M/s
Explanation:
The reaction rate is the rate at which the reaction takes place and results in an increased concentration of the products. The rate of the reaction is 0.0123 M/s.
What is the reaction rate?
The reaction rate is the increase of the concentration of the product with respect to time in seconds. The rate of reaction is given by,

there are several isomers with the formula c3h9n. one of them cannot form an h-bonding interaction with another identical molecule, but can do so with a water molecule. draw that isomer.
Answers
The isomer that cannot form an H-bonding interaction with another identical molecule, but can do so with a water molecule, is the primary amine isomer (C3H9N).
The primary amine isomer (C3H9N) has the following structure: H3C-CH2-CH2-NH2.This isomer cannot form H-bonding interactions with another identical molecule because it lacks a hydrogen atom bonded to the nitrogen atom. In order for H-bonding to occur between two molecules, there must be a hydrogen atom bonded to an electronegative atom (such as nitrogen, oxygen, or fluorine) and a lone pair of electrons on the electronegative atom.
In the case of the primary amine isomer, there is only one hydrogen atom bonded to the nitrogen atom, and it is already involved in forming an H-bond with a water molecule.However, the primary amine isomer can form an H-bonding interaction with a water molecule. The lone pair of electrons on the nitrogen atom can act as a hydrogen bond acceptor, while the hydrogen atom bonded to the nitrogen can act as a hydrogen bond donor. This interaction can occur between the lone pair of electrons on the oxygen atom of water and the hydrogen atom bonded to the nitrogen of the primary amine isomer.
In summary, the primary amine isomer (C3H9N) cannot form an H-bonding interaction with another identical molecule due to the lack of a hydrogen atom bonded to the nitrogen. However, it can form an H-bonding interaction with a water molecule.

How much gravitational potential energy is in a 100-kg diver on a 10-m platform?
Answers
The gravitational potential energy in a 100-kg diver, at 10-m, is 9800 J.
The gravitational potential energy of an object is calculated by using the formula:
Pe = mgh
Where PE is the potential energy, m is the mass of the object, g is the acceleration due to gravity, and h is the height of the object above the ground.
Given that the mass of the diver is 100 kg and the height of the platform is 10 m, we can plug these values into the formula to find the potential energy:
PE = (100 kg)(9.8 m/s²)(10 m)
PE = 9800 J
Therefore, the gravitational potential energy of the 100-kg diver on the 10-m platform is 9800 J.

Answers
The concentration of hydroxide ions is roughly 2.53 x 10-9 M. The closest value is 3.0 x 10-9, but the right response is A) 2.97 x 10⁻¹⁰, which is the outcome in rounded significant figures.
What is the H+ and OH concentration?This indicates that the pH and pOH are both 7.00 and that the concentrations of [H+] and [OH-] are both 1.0 10-7 M at typical temperatures, more particularly, at room temperature.
The equation for the ion product of water can be used to get the hydroxide ion concentration given the hydrogen ion concentration:
Kw = [H+][OH-]
where Kw is the ion product constant of water, which is equal to 1.0 x 10⁻¹⁴ at 25°C.
Rearranging the equation, we get:
[OH-] = Kw/[H+]
When we replace the specified value of [H+], we obtain:
[OH-] = (1.0 x 10⁻¹⁴)/3.95 x 10⁻⁶
[OH-] = 2.53 x 10⁻⁹.

Answers
The VSEPR (Valence Shell Electron Pair Repulsion) model predicts the geometry of a molecule based on the number of electron domains around the central atom.
a) PCl3 has 4 electron domains (3 bonding pairs and 1 lone pair). The lone pair takes up more space than the bonding pairs, causing the molecule to have a trigonal pyramidal shape. The molecular geometry is therefore pyramidal.
b) CHCl3 also has 4 electron domains (3 bonding pairs and 1 lone pair), but the lone pair is repelled by the three bonding pairs, causing the molecule to have a tetrahedral shape. However, one of the positions is occupied by a non-bonding lone pair, making the molecular geometry trigonal pyramidal.
c) SiH4 has 4 electron domains (4 bonding pairs) and a tetrahedral shape. The molecular geometry is also tetrahedral.
d) TeCl4 has 5 electron domains (4 bonding pairs and 1 lone pair). The lone pair takes up more space than the bonding pairs, causing the molecule to have a seesaw shape. The molecular geometry is therefore seesaw-shaped.
In summary, the electron domain and molecular geometries of the given species are:
a) PCl3 - electron domain: 4, molecular geometry: pyramidal
