Carrying Capacity
Explanation:Carrying capacity is defined as the number of organisms that can survive in an environment based on the supplies in the area.
Carrying Capacity Limits
There are multiple variables that can affect carrying capacity. Some of the most common ones are food, water, and space. There is a limited amount of all of these things, which means that the environment can only support a specific amount of organisms. In this case, there is enough food for 150 wolves; thus the carrying capacity is 150.
Changes in Carrying Capacity
Carrying capacity can change throughout time. If the amount of food, water, or space increases, then the carrying capacity will as well. The opposite is also true. So, if suddenly there was enough food for 200 wolves, the carrying capacity would become 200.

Find the moles of sulfur produced, if 2.5 moles of sulfur
dioxide are used in the following chemical reaction.
SO2 + 2H2S + 2H2O + 3S
a 7.5 mol
Answer:
7.5mols of S
Explanation:
just make sure your equation is balanced, and in this case it's balanced,
so now you can do more to more ratio.
so in this case we are dealing with SO2 and S.
According to our balanced equation we have 1 mol of SO2 producing 3mols of S, i.e
1mol(SO2). : 3mols(S)
we've been asked that if we use 2.5 moles of SO2, how many moles of S will be produced?
So, this is how we can determine the number of moles of S that will be produced .
SO2 : S
1mol : 3mols(S)
2.5mols: x
we cross multiply
x=2.5×3
x=7.5mols of S.
.: if we use 2.5 mols of SO2,, 7.5mols of Sulfur will be produced

What is the equilibrium constant, K, for the following reaction, if the concentration of N2 was measured to be 0.521 M, H2 was measured to be 0.482 M, and NH3 was measured to be 3.17 M
The equilibrium constant is the relation between the products and the reactants of the reaction. The K, for the reaction, is 172.
What is the equilibrium constant?The equilibrium constant (K) is the relationship in the form of a ratio that denotes the concentration of the products to the reactants in a reaction.
The balanced chemical reaction is shown as,
[tex]\rm N_{2}(g) + 3H_{2}(g) \leftrightharpoons 2NH_{3}(g)[/tex]
Given,
Concentration of nitrogen =0.521 M
Concentration of hydrogen = 0.482 M
Concentration of ammonia = 3.17 M
The value of K is calculated as:
[tex]\begin{aligned} \rm K &= \rm \dfrac{[NH_{3}]^{2}}{[N_{2}][H_{2}]^3}\\\\&= \dfrac{(3.17)^{2}}{(0.521)(0.482)^{3}}\\\\&= 172\end{aligned}[/tex]
Therefore, the equilibrium constant for the reaction is 172.

can waves travel through empty space? why?
Answer:
Elctromagnetic waves can travel through empty space.
Explanation:
Waves that may pass through matter or empty space are known as electromagnetic waves. The electromagnetic field, like the other basic fields, penetrates the whole universe, including the region we refer to as empty space. There are no fields in space. The medium through which electromagnetic waves travel is called the electromagnetic field.
Calculate the number of copper atoms in 2.45 mole of copper
Answer:
1.48×10²⁴ Cu atoms
Explanation:
For this question you need to use Avogadro's number 6.022×10²³atoms.
2.45 moles of Cu ×[tex]\frac{6.022x10x^{23} atoms }{1 mole}[/tex]= 1.47539×10²⁴ atoms.
The moles cancel out so you are left with atoms.
Since there are 3 significant figures in the question there should be 3 significant figures in your answer, which is 1.48×10²⁴ Cu atoms.

10. If 200 mL of gas weighs 0.344 grams at STP, what is its molecular mass? (1000 mL = 1 L)
The molecular mass of the gas if 200 mL of gas weighs 0.344 grams at STP is 38.53g/mol. Details on how to calculate molecular mass can be found below.
How to calculate molecular mass?The molecular mass of a gas can be calculated by using the following expression:
At STP, the gas weighs 0.344 grams. volume = 200mL = 0.2LMolecular weight of the gas = mass × volume at STP (22.4L)/ volume of gas
= 0.344 × 22.4/0.2
= 7.7056/0.2
= 38.53g/mol
Therefore, the molecular mass of the gas if 200 mL of gas weighs 0.344 grams at STP is 38.53g/mol.

Dominic made the table below to organize his notes about mixtures. A 1-column table. The first column labeled properties of mixtures has entries has no set composition, must have more than one state of matter, must have more than one substance. What mistake did Dominic make? The title should read “Properties of Solutions” because some mixtures do not have all of the properties listed. There is a definite recipe to make each mixture, so the composition of a mixture is set. Although it is possible to have more than one state, it is also possible to have only one state. A single substance can be used to make a mixture if the substance is composed of more than one element.

Assume that the mass of the Cu electrode changes by x grams in a certain period of time. Write a mathematical expression for the change in mass of the Zn electrode during the same period of time.
Assuming the quantity of current passing through the zinc and copper electrolytes is the same, mass of Zinc deposited is (x/64) × 65.0 g.
What is electrolysis?Electrolysis is the decomposition of a substance known as an electrolyte when electric current is passed through its solution or molten form.
The mass of an electrolyte deposited when current is passed is dependent on the current and the charge on the ion.
In the electrolysis of copper and zinc, assuming the quantity of current passed through their solution are the same, the moles of each zinc and copper deposited will be the same since the charges on their ions are the same.
Assuming x g of copper is deposited.
molar mass of copper = 64.0 g
molar mass of Zinc = 65.0 g
moles of copper deposited = x/64
moles of zinc deposited = x/64
mass of Zinc deposited = (x/64) × 65.0 g
Therefore, the mass of Zinc deposited is (x/64) × 65.0 g.
