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.

granular fertilizer plus postemergence herbicide products are more expensive than sprayable postemergence herbicide products per unit area treated given that the active ingredients are the same in both products.
The statement 'granular fertilizer plus postemergence herbicide products are more expensive than sprayable postemergence herbicide products per unit area treated given that the active ingredients are the same in both products' is true.
When the fertilizer is in a granular form, it is more expensive than a fertilizer in a sprayable form. Fertilizers can be described as chemicals that are added to soil in order to improve the nutritional content of the soil.
In the granular form, a fertilizer and a herbicide will be present as two different products, the cost of both will be different and hence more expensive combined. In a sprayable form, the postemergence herbicide and the fertilizer can occur together inside a spray and hence is cheaper.

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.
Therefore, the mass of CaSO₄ were obtained from the reaction is 41.53 g.

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.

if the volume remains constant, what is the final pressure is 3.75ATM.
What is pressure?
pressure is continues physical force exerted on or against an object by something in contact with.
Pressure is the force applied perpendicular to the surface of an object per unit area over which that force is the distributed. Gauge pressure by this is the pressure which relative to the ambient by its pressure. Various units are the used to express pressure.
Applying gas law formulae:
P1/T1 = P2/T2
Where P1 = initial pressure (atm) = 7.5
T1 = initial temperature in Kelvin(K) = 448
P2 = final pressure (atm) = unknown
T2 = final temperature in Kelvin(K) = 224
From the above Formula make P2 the subject of formula
P2 = P1T2/T1
P2 = 7.50*224/448
P2 = 1680/448
P2 = 3.75ATM
