Answer:

You would have 1.96 moles.

Explanation:

You are given 608 grams of calcium phosphate Ca₃(PO₄)₂.

Molar mass (M) is the amount of mass that a substance contains in one mole. This substance can be an element or a compound.

Since the molar mass of the compound Ca₃(PO₄)₂ is 310 g / mole, and taking into account the definition of molar mass, you can apply the following rule of three: if 310 grams of Ca₃(PO₄)₂ are contained in 1 mole, 608 grams of the compound in how many moles are present?

[tex]moles=\frac{608 grams* 1 mole}{310 grams}[/tex]

moles= 1.96

You would have 1.96 moles.

Molarity= no. of moles of solute/ volume of solution(in L)

Molarity = 6.2 moles/ 2.5 L = 62/25 mol/L

= 2.48 mol/L

Answer:

i think it's Organization

Explanation:

The reason being is because they obviously said 'humans' so that's why i think it is Organization

Scientists group similar organisms together through the process called classification. Each similar groups is classified into different organizations.

The arrangement of species into groups according to significant similarities  is known as biological classification. Then, these groups are broken down into more focused, smaller subgroups. Additional details on the species that make up each subgroup are provided.

Organisms are categorized by scientists to make them simpler to research and to facilitate information sharing. Before biologists properly comprehended genetics, the study of biological classification was conducted.

At first, scientists simply categorized creatures based on their outward appearance. Later, as genetic research developed, classification of organisms was based on the genetic and evolutionary links between them.

Therefore, scientists classify each organisms to suitable organizations.

Answer:

10.56 moles of NO will be produced

Explanation:

The balanced reaction of ammonia, NH₃ with oxygen, O₂ is:

4NH₃ + 5O₂ → 4NO + 6H₂O

Where 5 moles of oxygen react with an excess of ammonia to produce 4 moles of nitrogen monoxude.

If 13.2 moles of O₂ react:

13.2 mol O₂ * (4 mol NO / 5 mol O₂) =

Answer:

The part labelled Y is the chloroplast and its main function is to produce food for the plant in the reactions of photosynthesis.

Explanation:

Plants are autotrophic organisms in that they are able to manufacture their own food. Plants are able to manufacture their own food due to the presence of the cell organelle known as the chloroplast.  The plant chloroplast has its own DNA and can reproduce independently, from the rest of the cell. They can as well produce amino acids and lipids required for the chloroplast membrane.

Chloroplasts are green-colored membrane-bound organelles found within the plant cell. Their green color is due to the presence of the pigment, chlorophyll. Chlorophyll in the chloroplasts are responsible for absorbing light energy from sunlight and using this absorbed energy to make simple sugars (carbohydrates) from carbon (iv) oxide and water. This is the main function of the chloroplasts in plant cells.

Photosynthesis occurs in the chloroplasts in two reaction steps:

1. The light reaction - involves the splitting of e=water molecules using the energy of sunlight

2. The dark reactions - carbon (iv) oxide from the air is used to produce sugars.

Answer:

[tex]0.30molNH_3[/tex]

Explanation:

Hello there!

In this case, since the reaction for the formation of ammonia is:

[tex]3H_2+N_2\rightarrow 2NH_3[/tex]

We can evidence the 1:2 mole ratio of nitrogen gas to ammonia; therefore, the appropriate stoichiometric setup for the calculation of the moles of the latter turns out to be:

[tex]0.15molN_2*\frac{2molNH_3}{1molN_2}[/tex]

And the result is:

Physical property

Explanation:

Change in state is a physical property of matter.

Answer:

1. B. Ammonia and hexane will not dissolve because one molecule is polar and the other is non polar.

2. 1400 mL

Explanation:

In chemistry, like dissolve like! Ammonia is a polar molecule having a significant dipole moment owing to its three N-H bonds. On the other hand, hexane is a purely non-polar hydrocarbon hence the two substances can never dissolve in each other.

From the dilution formula;

C1V1=C2V2

C1= Initial concentration of the solution

V1 = Initial volume of the solution

C2 = Final concentration of the solution

V2= Final volume of the solution

2.8 M * 750.0 mL = 1.5 M * V2

V2 = 2.8 M * 750.0 mL/1.5 M

V2 = 1400 mL

Food and cell type

Explanation:

Kingdoms are by far the most basic legal structure for living objects. Living objects are classified into realms depending on how they consume food, the kinds of cells that produce their bodies, and the total type of tissue in their bodies.

Answer:

Q = 219.07 J

Explanation:

Given that,

Mass of water, m = 15.4 g

The temperature changes from 22.2°C. to 25.6 °C.

The specific heat of water, c = 4.184 J/g °C

We need to find the heat needed to change in temperature. The formula is given by :

[tex]Q=mc\Delta T\\\\Q=15.4\times 4.184\times (25.6-22.2)\\\\Q=219.07\ J[/tex]

So, 219.07 J of heat is needed.

4 limiting factors could be water, space, pollution, and access to mates, could all be factors in limiting the native population. Water, could be affected by pollution, and this would remove water, which means that no living things would be able to survive, or at the best be hindered in its growth. Space could be removed by deforestation, or simple water rising, and this could kill off the population, thus removing mates for the population. (hope this helped, if it did, please consider marking brainiest)

The availability of food, water, shelter and diseases are the four limiting factors in the local ecosystem and their impact on native populations.

The limiting factors such as availability of food, water, shelter and diseases can change animal and plant populations because these factors has a direct impact on the organisms and the organisms is depend on these factors for their survival.

So we can conclude that availability of food, water, shelter and diseases are the four limiting factors in the local ecosystem and their impact on native populations.

Which solution is the least concentrated?

Answer:

12 atoms of hydrogen will be present in the product

Explanation:

12 atoms of hydrogen will be present in the product because the law of conservation of mass states that mass is neither created nor destroyed in chemical reactions.

The law of conservation states that the mass of the element remains the same during the course of the reaction.

The law of reaction conformed by the following:-  

According to the question, the amount of hydrogen is 12 atoms in the reactant and the amount will remain the same at the end of the reaction, which is a product that is 12 atoms

Hence, the amount remains the same in the reaction that is 12 atoms
