Answer: a) [tex]H_3PO_4+3NaOH\rightarrow Na_3PO_4+3H_2O[/tex]
b) [tex]PCl_3+3H_2O\rightarrow P(OH)_3+3HCl[/tex]
c) [tex]2Al+3H_2SO_4\rightarrow Al_2(SO_4)_3+3H_2[/tex]
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side.
The balanced chemical equations are :
[tex]H_3PO_4+3NaOH\rightarrow Na_3PO_4+3H_2O[/tex]
[tex]PCl_3+3H_2O\rightarrow P(OH)_3+3HCl[/tex]

Explanation:
the answer is sodium carbonate
how does the law of conservation of mass applies to all chemical reactions?
Answer:
the mass of any one element at the beginning of a reaction will equal the mass of that element at the end of the reaction. If we account for all reactants and products in a chemical reaction, the total mass will be the same at any point in time in any closed system.
Explanation:
The law of conservation is Matter cannot be created or destroyed in chemical reactions so it means exactly that

Which of the following halogens has the largest atomic radius?
a. Chlorine
b. lodine
c. Bromine
d. Fluorine
Answer:
[tex]\boxed {\boxed {\sf B. \ Iodine }}[/tex]
Explanation:
Atomic radius is the measurement from the nucleus to the outer edge of the electron cloud.
As you go down a group (vertically) the atomic radius increases because more electron shells are added. As you go across a period horizontally, the atomic radius decreases.
If we look at the halogens group (17), we see they follow this order from top to bottom:
F - Fluorine
Cl - Chlorine
Br - Bromine
I - Iodine
Since it increases down the group, iodine must have the largest atomic radius.

A : The densest material is closest to the center
B : The density material is farthest from the center.
C : The densest material is near the center
D : Density differences allow Earth materials to mix freely. ( science by the way )
Answer:
Earth has layers because of density. Dense materials such as iron sank to the middle of the Earth, the center of its gravity. Less dense materials stayed at the top.
Explanation:
hope this help:)
The answer to the question, How does density affect the organization of earth is A : The densest material is closest to the center
The earth is made up of different layers namely,
The crustThe upper mantleThe lower mantleThe outer core andThe inner core.Each layer goes from topmost to inner most and the density of each layer increases as we moves closer to the center of the earth.
So, the densest material is closest to the center.
So, the answer to the question, How does density affect the organization of earth is A : The densest material is closest to the center

Zinc sulfide and oxygen gas react to form zinc oxide and sulfur dioxide. Determine the amount (g) of SO2 that should be produced in a reaction between 32.5 g of ZnS and 23.3 g of oxygen gas. What is the mass of the xs reactant?
Answer:
7.30g O₂ are in excess and 21.3g of SO₂ should be produced.
Explanation:
The reaction of Zinc sulfide (ZnS) with oxygen (O₂) produce ZnO and SO₂ as follows:
2ZnS + 3O₂ → 2ZnO + 2SO₂
Using this reaction we can find the amount of SO₂ produced converting the ZnS and O₂ to moles and finding limiting and excess reactant as follows:
Moles ZnS -Molar mass: 97.47g/mol-:
32.5g * (1mol / 97.47g) = 0.333 moles ZnS
Moles O₂ -Molar mass: 32g/mol-:
23.3g O₂ * (1mol / 32g) = 0.728 moles O₂
For a complete reaction of the 0.333 moles of ZnS are required:
0.333 moles ZnS * (3mol O₂ / 2mol ZnS) = 0.500 moles O₂.
As there are 0.728 moles of O₂, limiting reactant is ZnS and excess reactant is O₂.
The moles and mass of O₂ in excess are:
0.728mol - 0.500mol = 0.228moles O₂ * (32g / mol) = 7.30g O₂ are in excess
The produced mass of SO₂ -Obtained from the moles of ZnS- is:
0.333 moles of ZnS * (2mol SO₂ / 2mol ZnS) = 0.333 moles SO₂
0.333 moles SO₂ * (64.066g / mol) =
21.3g of SO₂ should be producedname the stages of the water cycle
