The given reaction is the type of Decomposition reaction. A decomposition reaction occurs when one reactant splits into many products.
What does a reaction's breakdown entail?Chemistry reaction reactions of decomposition. Decomposition reactions occur when complex chemical entities split apart into smaller components. Decomposition reactions often demand energy input.
What are the names for decomposition reactions?Decomposition reactions are those that divide or break the compounds into two simpler products. Because two or more reactants are combined to create a single product in a combination reaction, they are known as the reverse of combination reactions.
The exothermic nature of a decomposition reaction is why?It entails the severing of ties. Energy is necessary to dismantle the bonding between atoms. Decomposition advances when energy in the form of heat or electricity is provided. As the bond is broken during this reaction, energy is given to them, making them endothermic processes.

What is the formula for the compound formed by Al3+ and N3- ?
Answer:
[tex]\boxed {\boxed {\sf AlN}}[/tex]
Explanation:
The goal when forming compounds is to achieve a net charge of 0.
We are given aluminum with a charge of 3+ and nitrogen with a charge of 3-.
These charges are equal and opposite, so one of each will equal 0.
3+ (Al) + 3- (N) = 0Therefore, we do not need any subscripts. List the metal's symbol (aluminum) then the nonmetal.
AlNTh formula for the compound, which is aluminum nitride, is AlN.
What is the pH of a 2.0 × 10-4 M HCl solution?
Answer:
pH = 3.69
Explanation:
HCl is a strong acid. It will disscociates completely into dissoluted ions such that,
[tex][H^+]=2\times 10^{-4}\ M[/tex]
The formula for pH is given by :
[tex]pH=-log[H^+]\\\\pH=-log(2\times 10^{-4})\\\\pH=3.69[/tex]
So, the pH of the solution is 3.69.

Please no Bs answers. Only going to be reported.
If water is added to 145 mL of a 0.55 M KOH solution until the volume is 250 mL, what will the molarity of the diluted solution be?
What is the molarity of the solution that results from diluting 35.0 ml of a 9.02M solution to a new volume of 45.0 ml?
We can use the equation for dilutions that relates concentration and volume:
[tex]M_1V_1=M_2V_2[/tex]
where M is the molarity, V is the volume, and 1 and 2 refer to the initial and final states of the solution, respectively. Here, we are given the molarity of the initial solution and the volumes of the initial and final (diluted) solutions. To find the final concentration (i.e., the molarity of the diluted solution), we would be solving for M₂:
[tex]M_2=\frac{M_1V_1}{V_2} = \frac{(0.55 \text{ M})(145 \text{ mL})}{250 \text{ mL}} \\ M_2 = 0.319 \approx 0.32 \text{ M}.[/tex]
The molarity is given to two significant figures as both our M₁ and V₂ are given to two significant figures.
Note: Although our volumes are in mL instead of L, we do not need to convert them to L for the purposes of our calculation since we would be multiplying our V₁ and V₂ by a common factor that would cancel out in division. All that matters is the ratio between the two volumes, which is the same whether the volumes are in mL or in L.
---
We follow the exact same procedure in the second question as we did in the first problem: solve for M₂ given M₁ = 9.02 M, V₁ = 35.0 mL, and V₂ = 45.0 mL:
[tex]M_2=\frac{M_1V_1}{V_2} = \frac{(9.02 \text{ M})(35.0 \text{ mL})}{45.0 \text{ mL}} \\ M_2 = 7.02 \text{ M}.[/tex]

Which of the following examples best describes an effect of urbanization?
A More land is available in large cities to grow crops.
B Wildlife diversity increases due to more open spaces within the city.
C Emissions from motor vehicles increase smog in the air that can block radiation.
D The greater concentration of people in large cities reduces overall waste production and accumulation on Earth.

Emissions from motor vehicles increase smog in the air which can block radiation. Hence, option C is correct.
What does it mean to live in an urban area?An urban area is a region surrounding a city. Most inhabitants of urban areas have nonagricultural jobs. Urban areas are very developed, meaning there is a density of human structures such as houses, commercial buildings, roads, bridges, and railways. "Urban area" can refer to towns, cities, and suburbs.
Emission from motor vehicles increases smog in the air that can block radiation, which makes sense because urbanization means more people in one area=lots of pollution.
Hence, option C is correct.

how many grams of iorn reacts with 71 grams of chlorine to produce 117 grams of sodium chloride
Answer:
The answer to your question is: 71 g of Chlorine
Explanation:
Na = 46 g
Cl = ?
NaCl = 117 g
Equation
2 Na + Cl₂ ⇒ 2 NaCl
46g X 117g
If we consider the law of conservation of matter, we know that the mass of the reactants equals the mass of the products, then
mass Na + mass Cl₂ = mass NaCl
46 g + X = 117
X = 117 - 46
x = 71 g of Chlorine
Which of these indicates that a liquid has transferred thermal energy to the air?
O The liquid increases in temperature, and its particles lose kinetic energy
O The liquid decreases in temperature, and its particles gain kinetic energy
O The liquid increases in temperature, and its particles gain kinetic energy.
O The liquid decreases in temperature, and its particles lose kinetic energy
No
Answer:
The liquid decreases in temperature and its particles lose kinetic energy.
Temperature is proportional to kinetic energy, so if temperature decreases, kinetic energy decreases. Energy has been removed from the liquid, because it is in the air

A reaction is expected to produce 28.3 moles of hydrogen gas. If the hydrogen is collected at 297 K and 1.08 atm, what is the volume? 305 L H2 639 L H2 948 L H2 1,240 L H2
Answer:
The correct answer is 639 L H₂
Explanation:
We use the ideal gas equation:
We have the following data:
n = 28.3 mol
T= 297 K
P= 1.08 atm
R= 0.082 L.atm/K.mol (gas constant)
We introduce the data in the gas equation to calculate the volume (V):
PV=nRT
⇒V =nRT/P = (28.3 mol x 0.082 L.atm/K.mol x 297 K)/(1.08 atm) = 638.2 L ≅ 639 L
Therefore, the correct option is 639 L H₂
Answer:
639 L H2

THE MYSTERY SALT
Imagine that you have a barrel of salt, but you forgot to label it. You know it must be either KNO3, or KCl.
You look at the solubility curves for KNO3 and KCl and you find that at 35 degrees Celsius, 100 g of water can dissolve about 30 g of KNO3, or about 37 g of KCl.
The solubility curves disappear. You only remember the solubility for both salts at 35 degrees Celsius in 100g of water. You know absolutely nothing else about these salts.
You have a scale, a hot plate, a thermometer, empty beakers, and plenty of water. You do NOT have any labeled KNO3 or KCl.

The mass of a single gold atom is 3.27X10^-22 grams. How many gold Adams with there be in 57.8 mg of gold.
Answer:
18 * 10^19 atoms
Explanation:
We must first convert 57.8 mg to grams.
If 1000 mg = 1g
57.8 mg = 57.8/1000 = 57.8 * 10^-3 g
Now;
If 1 gold atom has a mass of 3.27X10^-22 grams
x gold atoms have a mass of 57.8 * 10^-3 g
x = 57.8 * 10^-3 g/3.27X10^-22 g
x = 18 * 10^19 atoms
