How should the heat of the reaction for neutralization of naoh and two acid compare?.
HCl and NaOH reaction has a larger heat of neutralization. Acetic acid and NaOH reaction has a larger heat of neutralization.
Enthalpy of neutralization is the heat evolved when one gram equivalent of the acid is completely neutralized by a base in the dilute solution. . 13.7 kcal of heat is liberated out and is the heat of neutralization for all strong acids and bases.
Neutralisation is a chemical reaction where an acid and a base react with each other quantitatively. It is also written as Neutralisation. The acid strength of the reactant gives the pH of the neutralized solution

What happens when unbalanced forces act on an object at rest?.
An item will move and its velocity will vary when unbalanced forces are applied to it while it is at rest. Keep in mind that a change in velocity can result from changes in either direction or speed.
When a force acts on an object, the thing changes size or shape, begins to move, stops moving, accelerates, or decelerates. When two objects interact, they each apply a force that is equal in magnitude but directed in the opposite direction with some velocity.
An object in motion can also be stopped by unbalanced forces. Wind resistance, gravity, and friction are the three basic forces that slow moving objects down. Balanced forces are equal forces acting in opposing directions.

according to the following reaction, how many grams of calcium hydroxide are required for the complete reaction of 22.6 grams of sulfuric acid? sulfuric acid (aq) calcium hydroxide (s) calcium sulfate (s) water (l)
The correct answer is 41.53 g.
We'll begin by writing the balanced reaction. This is illustrated below:
H₂SO₄ + Ca(OH)₂ —> CaSO₄ + 2H₂O
Next, we shall determine the mass of Ca(OH)₂ that reacted and the mass of CaSO₄ produced from the balanced reaction. This can be obtained as follow:
Molar mass of Ca(OH)₂ = 40 + 2(16 + 1)
= 40 + 2(17)
= 40 + 34
= 74 g/mol
Mass of Ca(OH)₂ from the balanced reaction = 1 × 74 = 74 g
Molar mass of CaSO₄ = 40 + 32 + (16×4)
= 40 + 32 + 64
= 136 g/mol
Mass of CaSO₄ from the balanced reaction = 1 × 136 = 136 g
From the balanced reaction above,
74 g of Ca(OH)₂ reacted to produce 136 g of CaSO₄.
Finally, we shall determine the mass of CaSO₄ produced by the reaction of 22.6 g of Ca(OH)₂. This can be obtained as follow:
From the balanced reaction above,
74 g of Ca(OH)₂ reacted to produce 136 g of CaSO₄.
So, 22.6 g of Ca(OH)₂ will react to produce = (22.6 × 136)/74 = 41.53 g of CaSO₄.

what total energy (in kj) is contained in 1.00 moles of photons, all with a wavelength of 0.00000187 m? your answer should have three significant figures and no units.
The total energy contained in a given number of photons depends on the energy of each photon. The energy of a photon is directly proportional to its frequency and inversely proportional to its wavelength.
To find the energy of a photon with a given wavelength, you can use the formula E = h * c / lambda, where E is the energy of the photon, h is the Planck constant (6.62607015 x 10^-34 J*s), c is the speed of light (2.99792458 x 10^8 m/s), and lambda is the wavelength of the photon.
In this case, the wavelength of the photon is 0.00000187 m, so the energy of a single photon would be: E = 6.62607015 x 10^-34 J * s * 2.99792458 x 10^8 m/s / 0.00000187 m = 1.97639 x 10^-19 J.
If we have 1.00 moles of photons, each with an energy of 1.97639 x 10^-19 J, the total energy contained in the photons would be the number of photons times the energy of each photon. One mole of any substance contains 6.02214076 x 10^23 particles, so 1.00 moles of photons would contain 6.02214076 x 10^23 photons.
To find the total energy contained in 1.00 moles of photons with a wavelength of 0.00000187 m, we can multiply the number of photons by the energy of each photon: 6.02214076 x 10^23 photons * 1.97639 x 10^-19 J/photon = 1.1933 x 10^5 J.
To convert this to kJ, we can divide by 1000 to get 119.33 kJ. Rounded to three significant figures, the total energy contained in 1.00 moles of photons with a wavelength of 0.00000187 m would be 119 kJ.

What produces the most CO2?The use of fossil fuels including coals, natural gas, or oil is one of the major sources of dioxide emissions, accounting for 87 percent of all emissions produced by humans. The burning of fossil fuels is the major human emission source of carbon dioxide.
Briefing:The chemical process looks balanced like this:
2C₄H₁₀(g)+13O₂(g)→8CO₂(g)+10H₂O(g)
Since 1 mole if butane combines using 13 moles or oxygen in the reaction described above, 3.5 moles for butane will need:
Required moles of O₂=3.12×13mol
Required moles of O₂=40.5mol
moles of O₂=8×12.69÷13
moles of O₂=7.80mol
As a result, 7.80 moles if carbon dioxide will be produced.
