Answer:  The bonds that are made and broken in a reaction release energy when forming products that contain less total energy than the reactants.

Explanation:  Elements form bonds with each other when the total energy of the resulting products is less than the starting energy.  The term "energy" refers to the energy of the electrons that are being held in an atom by the nucleus.  Keeping the positively charged nucleus happy means that the electrons are trying to get closer, but they repel each other as they get closer to the nucleus.  This results in orbits, preferred areas around the nucleus where the electrons spend their day in a delicate balance with the nucleus and other electrons.  These orbits offer housing for the electrons that involve discreet energies for the electrons.  When elements react, the resulting bonding pattern often results in an overall reduction in total energy.  The energy reduction results in heat, light, and/or sound.  The release is termed "exothermic."

Respuesta:

1.50 moles

Explicación:

Paso 1: Escribir la ecuación química ajustada para la descomposición del carbonato de calcio

CaCO₃ ⇒ CaO + CO₂

Paso 2: Calcular los moles correspondientes a 150 g de CaCO₃

La masa molar de CaCO₃ es 100.09 g/mol.

150 g × 1 mol/100.09 g = 1.50 mol

Paso 3: Calcular los moles de CO₂ producidos a partir de 1.50 moles de CaCO₃

La relación molar de CaCO₃ a CO₂ es 1:1.

1.50 mol CaCO₃ × 1 mol CO₂/1 mol CaCO₃ = 1.50 mol CO₂

D

Explanation: Got it correct on edge 2022

Answer:

Pull

Explanation:

The higher the effective nuclear charge, the more the nucleus will be gaining protons. This process makes the electrons to be drawn closer to the positive charge of the nucleus.

Thus, it leads to a greater pull exerted by the nucleus on the added electrons.

Lets take an example to explain this

Sodium(Na) has 1 electron in its outer or valence shell hence it will lose it and become a cation say to Chlorine(Cl)

To form Sodium Chloride.

Since it is capable of losing electrons, Sodium becoems a metal and has properties of metal

Whereas Chlorine which has 7 electrons in its valence shell gains an electrons to become an anion

Hence it is a non metal

And has the properties of an anion

D. Electrical energy is changed into mechanical energy

Explanation:

When you turn on the fan, the electricity that is given through the power outlet allows the fan to have the available energy to spins the fan blades. By the fan's blades spinning, this is a movement that can be described as mechanical energy.

Answer:

67.3 kPa

Explanation:

We're focusing on pressure and volume of gases, so we can use our ideal gas law formula PV=nRT. Everything is constant except pressure and volume, but the values change when moving from city 1 to city 2, so we can say PV city 1= PV city 2.

We can simplify our formula to be P1V1=P2V2. This is specifically Boyle's Law, where if pressure increases (from city 1 to city 2) then volume decreases, thus we can say pressure and volume have an inverse/opposite relationship.

This is an important formula to understand, you can easily memorize it by referring to PV=nRT.

Let's plug in the values we know.

P1V1=P2V2

(101)(6) = (9)(V2)

Now let's solve for V2.

[tex]\frac{101 x 6}{9}[/tex]  = V2

[tex]\frac{606}{9}[/tex] = V2

67.3 kPa = V2

Uses of Rutherfordium

Because rutherfordium is made within the lab, there are not very many uses for this element commercially. On the other hand, rutherfordium has been used within the laboratory setting to conduct research. Most elements that are highly radioactive are used for nuclear power and medicinal purposes.

Answer:

35.8 g

Explanation:

Step 1: Given data

Mass of water: 63.5 g

Step 2: Calculate how many grams of KCl can be dissolved in 63.5. g of water at 80 °C

Solubility is the maximum amount of solute that can be dissolved in 100 g of solute at a specified temperature. The solubility of KCl at 80 °C is 56.3 g%g, that is, we can dissolve up to 56.3 g of KCl in 100 g of water.

63.5 g Water × 56.3 g KCl/100 g Water = 35.8 g KCl

Answer:

For the reaction to be spontaneous at high temperatures, ΔG < 0 and, ΔH > 0 and ΔS > 0.

Explanation:

According to the Gibbs free energy equation, for the reaction to be spontaneous at high temperatures when it was not spontaneous at low temperatures, the free energy change ΔG < 0.

Since ΔG = ΔH - TΔS where ΔH = enthalpy change and ΔS = entropy change,

For ΔG < 0 at high temperatures, ΔH > 0 and ΔS > 0. That is both ΔH and ΔS are positive at high temperatures.

So, for the reaction to be spontaneous at high temperatures, ΔG < 0, and ΔH > 0 and ΔS > 0.

When ΔH and ΔS are both positive

Answer:

4121 years

Explanation:

From;

0.693/t1/2 = 2.303/t log No/N

t1/2= half life of the carbon-14

No= count rate of the living tissue

N= count rate of the sample

t = age of the sample

0.693/5730 =2.303/t log (13.5/8.2)

1.21 * 10^-4 = 2.303/t * 0.2165

1.21 * 10^-4 = 0.4986/t

t = 0.4986/1.21 * 10^-4

t = 4121 years

Answer:

4.58g of CO₂ could be produced

Explanation:

Based on the reaction:

C₂H₄(g) + 3O₂(g) → 2CO₂(g) + 2H₂O(g)

1 mole of C₂H₄ reacts with 3 moles of oxygen to produce 2 moles of CO₂

To solve this question we must find the moles of each reactant in order to find limiting reactant. With limiting reactant we can find the moles -And the mass- of CO₂ produced:

Moles C₂H₄ -Molar mass: 28.05g/mol-

2.0g * (1mol / 28.05g) = 0.0713moles

Moles O₂ -Molar mass: 32g/mol-

5.0g * (1mol / 32g) = 0.156moles

For a complete reaction of 0.0713 moles of C2H4 are required:

0.0713 moles C₂H₄ * (3 moles O₂ / 1 mol C₂H₄) = 0.214 moles of O₂

As there are just 0.156 moles, O₂ is limiting reactant.

The moles of CO₂ produced are:

0.156 moles O₂ * (2mol CO₂ / 3mol O₂) = 0.104 moles CO₂

The mass is -Molar mass CO₂: 44.01g/mol-

0.104 moles CO₂ * (44.01g / mol) =
