If 4.36 mol of potassium phosphate react, how many grams of barium phosphate are produced?

Answers

Hello Mistyann!

First you need to know amount of barium phosphate is

Half of potassium phosphate, also 2.18 mol.

Molar mass of Barium phosphate is 3·137.2 + 2·(30.97+4·16) g/mol

You can calculate it yourself dear.

Now mass is amount of substance · molar mass.

It has been an honour to teach you, dear,

God bless!

Answer: Oxidation half: [tex]2Ag\rightarrow 2Ag^++2e^-[/tex]

Reduction half: [tex]2H^++2e^-\rightarrow H_2[/tex]

Explanation:

Oxidation-reduction reaction or redox reaction is defined as the reaction in which oxidation and reduction reactions occur simultaneously.

[tex]2Ag(s)+H_2S(s)\rightarrow Ag_2S(s)+H_2(g)[/tex]

Oxidation reaction is defined as the reaction in which a substance looses its electrons. The oxidation state of the substance increases.

Oxidation half: [tex]2Ag\rightarrow 2Ag^++2e^-[/tex]

Reduction reaction is defined as the reaction in which a substance gains electrons. The oxidation state of the substance gets reduced.

Reduction half: [tex]2H^++2e^-\rightarrow H_2[/tex]

electrons?

Answers

Ionic bonds form only between metals and nonmetals. That's because metals “want” to give up electrons, and nonmetals “want” to gain electrons. It takes energy to remove valence electrons from an atom and form a positive ion

Answer:

Ionic bonds form only between metals and nonmetals. That's because metals “want” to give up electrons, and nonmetals “want” to gain electrons. It takes energy to remove valence electrons from an atom and form a positive ion. Energy is released when an atom gains valence electrons and forms a negative ion.

Identify at least four limiting factors in the local ecosystem and their impact on native populations.

Answers

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.

What are the limiting factors?

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.

1. A balloon has 1.55 L of air in it exerting a pressure of 105.2 kPa. At

constant temperature, if the pressure increases to 122.0 kPa, what is the

volume?

Answers

Answer:

[tex]V_2=1.34L[/tex]

Explanation:

Hello there!

In this case, since this problem is describing how pressure changes as a function of volume and vice versa, it is possible recall the Boyle's law as shown below:

[tex]P_1V_1=P_2V_2[/tex]

Whereas we are asked to compute the volume when the change is pressure is performed (V₂); thus, we proceed as follows:

[tex]V_2=\frac{P_1V_1}{P_2}\\\\V_2=\frac{1.55L*105.2kPa}{122.0kPa}\\\\V_2=1.34L[/tex]

True or False: Ionic bonding means atoms COMPLETELY GIVE AWAY OR TAKE their electrons from each other. *

Answers

Answer: The given statement is True.

Explanation:

An ionic bond is formed when an element completely transfers its valence electron to another element. The element which donates the electron is known as electropositive element and the element which accepts the electrons is known as electronegative element. This bond is formed between a metal and an non-metal.

A covalent bond is formed when an element shares its valence electron with another element. This bond is formed between two non metals.

Thus the given statement is True.
