The amount of sodium chloride that would be formed if 92 g of sodium reacted with 142 g of chlorine would be 233.76 grams.

Sodium chloride is formed when sodium metal reacts with chlorine molecules according to the following balanced chemical equation:

\(2Na + Cl_2 -- > 2NaCl\)

The mole ratio of Na to Cl according to the equation is 2:1.

Recall that: mole = mass/molar mass

92 g of sodium is equivalent to = 92/23 = 4 mol

142 g of chlorine would be = 142/71 = 2 mol

Okay, so the two reactants balance stoichiometrically as well.

The mole ratio of Na to NaCl is 1:1, thus, 4 moles of NaCl would be formed as well.

Thus, 4 mol of NaCl would be equivalent to:

4 x 58.44 = 233.76 grams

In other words, the amount of NaCl that would be formed is 233.76 grams.

Answer:

its b because when the lava comes out it would run against the sides and since b is on the side it would run onto b

Explanation:

Answer:

Changing the subscripts in a chemical equation changes the identity and number of atoms in the molecules involved, which makes the equation incorrect. In the example given, changing the subscript in the product side of the equation from 1 to 2 results in the formation of hydrogen peroxide (H2O2) instead of water (H2O).

The equation H₂ + O₂ → H₂O₂ represents the reaction between hydrogen gas and oxygen gas to form hydrogen peroxide. However, this reaction is not balanced because the number of oxygen atoms on the product side is not equal to the number of oxygen atoms on the reactant side. In the reactant side, there are two oxygen atoms, while in the product side, there are two hydrogen atoms and two oxygen atoms. Therefore, this equation is incorrect and cannot be balanced by simply changing the subscripts.

To balance the equation correctly, coefficients should be added to the molecules to represent the number of atoms involved. For example, the balanced equation for the reaction between hydrogen gas and oxygen gas to form water would be:

2H₂ + O₂ → 2H₂O

This equation represents the balanced reaction where two molecules of hydrogen gas (H2) react with one molecule of oxygen gas (O2) to form two molecules of water (H2O), with equal numbers of atoms of each element on both sides of the equation.

In the electrophilic aromatic substitution reaction between benzaldehyde and Br2 in the presence of FeBr3, the first step involves the generation of a carbocation intermediate. This carbocation is formed when the bromine molecule attacks the benzene ring, displacing a proton.

Since benzaldehyde is a meta-director, the carbocation intermediate will be stabilized through resonance. The resonance structures can be represented as follows:

Structure 1:

      Br

       |

Ph-C(+)-H

       |

Structure 2:

      Br

       |

Ph-C-H

  |    |

  +    Ph

Structure 3:

      Br

       |

Ph-C-H

  |    |

Ph    +

In these resonance structures, the positive charge of the carbocation is delocalized throughout the benzene ring. The presence of the electron-withdrawing aldehyde group (CHO) in benzaldehyde directs the incoming bromine atom to the meta position relative to the aldehyde group.

Please note that it's always recommended to consult reliable sources and appropriate references for accurate structural representations.

a) The sphere emits thermal radiation at a rate of 139.75 Watts.

b) The sphere absorbs thermal radiation at a rate of 37.66 Watts.

c) The sphere's net rate of energy exchange is 102.09 Watts.

To calculate the rates of thermal radiation emission and absorption, we can use the Stefan-Boltzmann law, which states that the rate of thermal radiation emitted or absorbed by an object is proportional to its surface area, temperature, and the Stefan-Boltzmann constant.

a) The rate of thermal radiation emitted by the sphere can be calculated using the formula:

Emitting Rate = emissivity * surface area * Stefan-Boltzmann constant * (\(temperature^4 - environment\ temperature^4\))

Plugging in the given values:

Emitting Rate = \(0.924 * (4\pi * (0.457)^2) * 5.67 \times 10^{-8} * ((32.2 + 273.15)^4 - (82.9 + 273.15)^4)\)

Emitting Rate ≈ 139.75 Watts

b) The rate of thermal radiation absorbed by the sphere can be calculated in a similar way but using the environment temperature as the object's temperature:

Absorbing Rate = emissivity * surface area * Stefan-Boltzmann constant * (\(environment\ temperature^4 - temperature^4\))

Plugging in the given values:

Absorbing Rate = \(0.924 * (4\pi * (0.457)^2) * 5.67 \times 10^{-8} * ((82.9 + 273.15)^4 - (32.2 + 273.15)^4)\)

Absorbing Rate ≈ 37.66 Watts

c) The net rate of energy exchange is the difference between the emitting rate and the absorbing rate:

Net Rate = Emitting Rate - Absorbing Rate

Net Rate = 139.75 Watts - 37.66 Watts

Net Rate ≈ 102.09 Watts

Therefore, the sphere emits thermal radiation at a rate of 139.75 Watts, absorbs thermal radiation at a rate of 37.66 Watts, and has a net rate of energy exchange of 102.09 Watts.

Note: The units for all the rates are Watts.

Salts that will generate a basic solution: B) LiF, C) K²S, and J) K²CO³.

Salts that will generate a neutral solution: E) NaCH³COO, F) Csl, H) KBr, and I) FeCl³.

Different salts can generate solutions with varying pH levels, indicating their acidic, basic, or neutral properties.

The salts MgSO⁴, NH⁴CI, and Cu(NO³)² will generate acidic solutions when dissolved in water. This is because they release hydrogen ions (H⁺) into the solution, increasing its acidity.

On the other hand, salts like LiF, K²S, and K²CO³ will produce basic solutions. They contain hydroxide ions (OH⁻) or produce hydroxide ions when dissolved, which increase the concentration of hydroxide ions and raise the pH, making the solution more alkaline.

Salts such as NaCH³COO, Csl, KBr, and FeCl³ will lead to neutral solutions as they do not significantly affect the concentration of H⁺ or OH⁻ ions when dissolved.

The number of atoms in a mole (6.02 1023) of any material. We must use the conversion factor to change the number of atoms to the number of moles:  The mole, often known as mol, is a SI unit that counts the particles in a given material.

A fixed amount of atoms are measured in a mole. Mole conversions are possible for quantities like grammes and milligrammes. However, because a mole is the sum of all the atoms, it does not have a gramme or milligramme equivalent.

The number of atoms in a given amount of a substance can be calculated using Avogadro's number, which is equal to 6.022 × \(10^{23\) particles per mole.

The number of atoms in 1.5 moles of helium, we can multiply the number of moles by Avogadro's number:

Number of atoms = 1.5 moles × Avogadro's number

Answer

F) The pressure of a gas exerted on the walls of its container is inversely proportional to the volume of the gas when the temperature of the gas remains constant.

Explanation

Boyle's law states that the volume of a given mass of gas varies inversely with the pressure when the temperature is kept constant. An inverse relationship is described in this way. As one variable increases in value, the other variable decreases. He discovered that doubling the pressure of an enclosed sample of gas, while keeping its temperature constant, caused the volume of the gas to be reduced by half.

When the pool's center is occupied by the rubber raft. Think of it as the raft's starting position.

Once it reaches the rubber raft, the raft will start to rise when the friend creates a wave by slapping the water.

The raft will really gain energy from the wave, moving upward.

The raft will return to its original place once the wave passes.

The raft will return to its original place where it was before the wave hits it because it is indicated in the question that it is immobile.

As a result, the wave won't take it to the pool's edge.

Because you are only lightly lifted by the waves or because Lee cannot be pushed to the other side of the pool, the wave won't drive the person on the raft over the edge of the pool.

The gas law that defines the relation between volume and temperature is called Charles's law. The gas must be heated to 91 degrees celsius so that volume of 500 mL can be occupied.

"Charles's law is the ideal gas law that defines the relationship between the temperature and volume of the gas at the constant pressure." It describes how the gas expands and contracts at higher and lower temperatures.

The formula of Charles's law is given as:

V₁ ÷ T₁ = V₂ ÷ T₂

Given,

Initial temperature (T₁) = 0 degree celsius = 273 K

Initial volume (V₁) = 375 mL

Final temperature  = T₂

The final volume (V₂) = 500 mL

Substituting values in Charles's formulas as:

V₁ ÷ T₁ = V₂ ÷ T₂

T₂ = V₂T₂ ÷ V₁

T₂ = (500 mL × 273 K) / 375 mL

T₂ = 364 K

Converting K into degrees celsius as:

0 K − 273.15 = -273.1°C

364 K − 273.15 = 90.85 °C

Therefore, 91 °C is the final temperature of the gas.
