Answer: Acid rain is caused by a chemical reaction that begins when compounds such as sulphur dioxide and oxides of nitrogen are released into the air. These substances can rise very high up into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants called acid rain.
Explanation:
Equilibrium constant Kp for the reaction P4(s) + 6Cl2(g) 4PCl3(l) Kp = 1/ P6Cl2 Kp = P4Cl3/ P6P4 Kp = P4Cl3/ (P6P4) (P6Cl2) Kp = 1/ (P6P4) (P6Cl2)
Answer: [tex]K_p=\frac{1}{[p_{Cl_2}]^6}[/tex]
Explanation:
Equilibrium constant is defined as the ratio of pressure of products to the pressuure of reactants each raised to the power their stoichiometric ratios. It is expressed as [tex]K_p[/tex]
For the given chemical reaction:
[tex]P_4(s)+6Cl_2(g)\rightarrow 4PCl_3(l)[/tex]
The expression for [tex]K_p[/tex] in terms of gaseous is written as:
[tex]K_p=\frac{1}{[p_{Cl_2}]^6}[/tex]

How many moles of a gas would occupy 22.4 Liters at 273 K and 1 atm?
Read bottom comment
Answer:
The following relationship makes this possible: 1 mole of any gas at standard temperature and pressure (273 K and 1 atm) occupies a volume of 22.4 L.
Explanation:
1 mole of any gas would occupy 22.4L of gas at standard temperature and pressure (STP) i.e at 273K and 1 atm.
The STP conditions refer to the standard temperature and pressure. Pressure values at 1 atmosphere and temperature at 0 ° C (or 273 K) are used and are reference values for gases. And in these conditions 1 mole of any gas occupies an approximate volume of 22.4 liters.
An ideal gas is characterized by three state variables: absolute pressure (P), volume (V), and absolute temperature (T). The relationship between them constitutes the ideal gas law, an equation that relates the three variables if the amount of substance, number of moles n, remains constant and where R is the molar constant of the gases:
P V = n R T

What is the strong nuclear force?
A. An attractive force that holds the electrons close to the nucleus
B. A repelling force that pushes protons and neutrons apart
C. An attractive force that acts between protons and neutrons
D. A repelling force that pushes protons away from each other
An attractive force that holds the electrons close to the nucleus is the strong nuclear force
definition of nuclear force
The Strong Nuclear Force is an attractive force between protons and neutrons that keep the nucleus together and the Weak Nuclear Force is responsible for the radioactive decay of certain nuclei. It was realized that the strength of the two forces differed a lot. therefore option A is the correct answer.

Explanation:
How many grams of potassium chloride (KCl) can be produced from 180.6 g of chlorine (Cl2)?
Answer:
379.79 g of KCl
Explanation:
The balanced equation for the reaction is given below:
Cl₂ + 2KBr —> Br₂ + 2KCl
Next, we shall determine the mass of Cl₂ that reacted and the mass of KCl produced from the balanced equation. This can be obtained as follow:
Molar mass of Cl₂ = 70.90 g/mol
Mass of Cl₂ from the balanced equation = 1 × 70.90 = 70.90 g
Molar mass of KCl = 74.55 g/mol
Mass of KCl from the balanced equation = 2 × 74.55 = 149.1 g
SUMMARY:
From the balanced equation above,
70.90 g of Cl₂ reacted to produce 149.1 g of KCl.
Finally, we shall determine the mass of KCl produced by the reaction of 180.6 g of Cl₂. This can be obtained as follow:
From the balanced equation above,
70.90 g of Cl₂ reacted to produce 149.1 g of KCl.
Therefore, 180.6 g of Cl₂ will react to produce = (180.6 × 149.1)/70.90 = 379.79 g of KCl.
Thus, 379.79 g of KCl were obtained from the reaction.
If 0.525 moles of O2 are produced, how many moles of KClO3 are decomposed?
Answer:
B. 0.35mol KClO3
Explanation:
The balanced equation in this question is given as follows:
2KClO3 → 2KCl + 3O2
Based on the chemical reaction;
2 moles of KClO3 decomposes into 3 moles of O2
If 0.525 moles of O2 are produced, then:
= 0.525 × 2/3
= 1.05/3
= 0.35mol of KClO3 is decomposed.
En 50 gr de de agua se disuelven 10 gr de NaCl con una densidad de 1,08 m/cm3. Hallar la M y la m a. 3,06 M y 3,06m b. 3,06 M y 3,4 m c 3,4 M y 3,06 m d 3,5 M y 3,4 m
Answer:
Opcion b. 3.06M y 3.4 m
Explanation:
Nuestra solución se compone de:
Soluto → NaCl (10 g)
Solvente → agua (50 g)
Primero, convertimos la masa de soluto a moles:
10 g . 1mol / 58.45g = 0.171 moles
Convertimos la masa de solvente, de g a kg → 50 g . 1kg/1000 g = 0.05 kg
m → molalidad (tipo de concentración que relaciona los moles de soluto en 1kg de solvente)
m = mol/kg → 0.171 mol/0.05kg = 3.42 m
Para calcular M, necesitamos el volumen de solución, y para eso aplicamos densidad. Antes, sumamos masa de soluto + masa de solvente, para obtener la masa de solución
50 g + 10 g = 60 g de solución
d = m /v → v = m /d → 60g / 1.08g/cm³ = 55.5 cm³
cm³ = mL
M = molaridad, la concentración que relaciona los moles de soluto en 1L de solución, pero que también podemos predecir como los milimoles de soluto en 1 mL de solución.
El volumen de solución está en mililitros → 55.5 mL
Convertimos moles a milimoles → 0.171 mol . 1000 mmol /mol = 171 mmol
M = 171 mmol /55.5 mL → 3.08 M
14. Which type of bond is formed when an ammonia
molecule accepts a proton?
1) electrovalent
2) ionic
3) coordinate covalent
4) metallic
Answer: dative covalent bond
Explanation: one hydrogen ion is transferred from HCl to the lone pair on NH3 . This particular hydrogen only has its nucleus transferred—its electrons remain with chlorine. So, the bond between this particular hydrogen atom and the central nitrogen is a dative covalent bond.

If NaOH is added to 0.010 M Al3+, which will be the predominant species at equilibrium: Al(OH)3 or Al(OH)- 4 ? The pH of the solution is 14.00. [Kf for Al(OH) - 4 = 2.0 1033.]
Answer:
Al(OH)- 4,
Explanation:
NaOH added to 0.010 M Al3+
The predominant species at equilibrium will be = Al(OH)- 4, and this because sodium hydroxide ( NaOH ) is a base will readily form a stable complex ion with aluminum ion like ( Al( OH ) - 4 . also the higher the Kf value the more stable the complex ion becomes and the more soluble Al(OH)3 becomes
hence the predominant species at equilibrium is : Al(OH)- 4,
I am wondering how to find out the blood type of my grandson...my daughter is A+..father is in question...she is stressed to the max on the father of this baby boy.
Answer:
A person can identify their blood type at home using a rapid blood typing kit. Using the kit requires a person to pierce a finger with a needle. The kit comes with a card that contains chemicals known as reagents. These test for the presence of the antibodies and Rh factor.
Explanation:
Just like eye or hair color, our blood type is inherited from our parents. Each biological parent donates one of two ABO genes to their child. The A and B genes are dominant and the O gene is recessive. For example, if an O gene is paired with an A gene, the blood type will be A.
