How many grams of chlorine are required in order to consume 8 mol of
sodium?

The circulation of wind in the atmosphere is driven by the rotation of the earth and the incoming energy from the sun. Wind circulates in each hemisphere in three distinct cells which help transport energy and heat from the equator to the poles. The winds are driven by the energy from the sun at the surface as warm air rises and colder air sinks.

Answer: The circulation of wind in the atmosphere is driven by the rotation of the earth and the incoming energy from the sun. Wind circulates in each hemisphere in three distinct cells which help transport energy and heat from the equator to the poles.

Answer:

323 K

Explanation:

To convert Celcius to kelvin first you need to remember this equation:

C + 273 = K (K = kelvin and C = celsius)

Next, you substitute with what you have given:

50 + 273 = K

Solve the equation by adding 50 and 273

k = 323

Answer:Insects, such as water striders, and spiders, such as fisher spiders, can glide or scamper across the surface of water. These critters are small enough that their weight can be supported almost entirely by surface tension, the relatively weak forces that hold water molecules together.

Explanation:

Answer:

Examples of surface tension Water striders are able to walk on top of water due to a combination of several factors. Water striders use the high surface tension of water and long, hydrophobic legs to help them stay above water. Water striders use this surface tension to their advantage through their highly adapted legs and distributed weight.

Explanation:

The ability of a material, the solute, to combine with some other substance, the solvent, is known as solubility. Temperature of the water to the nearest degree is 110 °C for the given solubility.

The ability of a material, the solute, to combine with some other substance, the solvent, is known as solubility in chemistry. Insolubility, or the solute's inability to create such a solution, is the opposite property.

The concentration of a solute inside a saturated solution—a solution where no more solute could be dissolved—is typically used to gauge the degree of a substance's solubility in a particular solvent. Temperature of the water to the nearest degree is 110 °C for the given solubility.

pH, pOH, [H+], and [OH-] are all interrelated. For simplicity, we assume that we're working with aqueous solutions at 25 °C.

The following mathematical relations are relevant here:

A pH of 7 is neutral; a pH less than 7 is acidic; and a pH greater than 7 is basic.

---

We are given four solutions of varying [H⁺], and we want to find the pH and the [OH⁻]. The pH will tell us whether the solution is neutral, an acid, or a base.

Using the relationship [H⁺] × [OH⁻] = 10^-14, we can calculate the [OH⁻] of each solution by dividing 10^-14 by the given [H⁺]:

[OH⁻] = 10^-14/(3.3 × 10^-5) = 3.0 × 10^-10

[OH⁻] = 10^-14/(4.0 × 10^-8) = 2.5 × 10^-7

[OH⁻] = 10^-14/(7.2 × 10^-11) = 1.4 × 10^-4

[OH⁻] = 10^-14/(8.2 × 10^-4) = 1.2 × 10^-11

Note: While not indicated here, the units for [H⁺] and [OH⁻] are moles/liter (M).

To find the pH of each solution, we take the negative logarithm of the [H⁺] with base 10, i.e., pH = -log₁₀[H⁺]:

pH = -log(3.3 × 10^-5) = 4.48

pH = -log(4.0 × 10^-8) = 7.40

pH = -log(7.2 × 10^-11) = 10.14

pH = -log(8.2 × 10^-4) = 3.09

Note that, for significant figures involving logarithms, the number of decimal places should equal the number of significant figures in the argument of our logarithm (the argument is what we're taking the -log of). Since we're taking the -log of quantities given to two significant figures, our corresponding pH values are given to two decimal places.

As mentioned above, a pH = 7 is neutral, a pH < 7 is acidic, and a pH > 7 is basic.

4.48 < 7, so the first solution is an acid.

7.40 > 7, so the second solution is a base.

10.14 > 7, so the third solution is a base.

3.09 < 7, so the fourth solution is an acid.

Answer:

65.841 g

Explanation:

The balanced equation for this reaction is;

N2 + 3H2 → 2NH3  

From the question, we are interested in ammonia and the hydrogen gas.

From the equation

3 mol of H2 produces 2 mol of NH3

5.81 mol would produce x

Solving of x;

x = 5.81 * 2 / 3

x = 3.873 mol

Converting to mass;

Mass = Number of moles * molar mass

Mass =  3.873 * 17 = 65.841 g

Answer:

chemical change occured

Answer:

10 L

Explanation:

The equation of the reaction is;

2BaO2 = 2BaO + O2

Number of moles of  BaO2 = 114.7 g/169.33 g/mol = 0.677 moles

From the reaction equation;

2 moles of BaO2 yields 1 moles of O2

0.677 moles of BaO2 yields 0.677 * 1/2 = 0.3385 moles of oxygen

Hence;

PV=nRT

V = ?

P = 127400 Pa or 1.257 atm

T = 455 K

n = 0.3385 moles

R = 0.082 atmLmol-1K-1

V = nRT/P

V = 0.3385 * 0.082 * 455/1.257

V= 10 L

Answer:

Explanation:

The main reason is because they have different energy in the photon and different wavelength.

In the electromagnetic radiations, radio waves have little energetic photons, micro wave have more that radio waves, the visible light, ultraviolet x Ray's, and gamma Ray's have more energetic photons. They have different wavelength. The shorter the wavelength, the higher the frequency. Wavelength decreases while frequencies increases.

Once it's added to the atmosphere, it hangs around, for a long time: between 300 to 1,000 years. Thus, as humans change the atmosphere by emitting carbon dioxide, those changes will endure on the timescale of many human lives.

i just had a test on this with 2 attempts and got it wrong on both but i do know that the answer is not...

the steepness of the models hillside

or

the rate of erosion on the hills

so the answer is either...

the amount of water sprayed on the hills

or

the type of material used to construct the model hills

but i think its the amount of water sprayed on the hills...i hope i helped a lil ;)
