Explanation:

I hope it helps

ya welcome

Answer:

The polar water molecules exert strong cohesive forces on one another

Explanation:

The forces of cohesion refer to the strong attractive forces that molecules of a substance exert on each other.

This strong attractive force keeps the molecules of the water together and causes the water molecules to be pulled inside towards each other. We refer to this phenomenon as surface tension.

Hence, due to surface tension, water does not run off an inclined plane.

If the iodine atoms do not recombine to form I2, then the reaction that is taking place is I2 → 2I. This reaction is first order, which means that the rate of the reaction depends on the concentration of I2.

The rate law for this reaction is:

Rate = k[I2]

where k is the rate constant for the reaction.

To solve for the amount of I2 remaining after 5.12 s, we need to use the integrated rate law:

ln([I2]t/[I2]0) = -kt

where [I2]t is the concentration of I2 at time t, [I2]0 is the initial concentration of I2, k is the rate constant, and t is the time.

Rearranging this equation gives:

[I2]t = [I2]0 * e^(-kt)

We can find k by using the half-life of the reaction, which is 1.76 s at this temperature.

t1/2 = ln2/k

k = ln2/t1/2

k = ln2/1.76 s

k = 0.393 s^-1

Now we can plug in the values and solve for [I2]t:

[I2]t = 0.030 M * e^(-0.393 s^-1 * 5.12 s)

[I2]t = 0.018 M

Therefore, after 5.12 s, 0.018 M of I2 will remain assuming that the iodine atoms do not recombine to form I2.

Answer:

because when it burns reacts with oxygen forming mg oxide

If an isotope lies above the band of stability on a plot of neutrons vs protons, it will decay via beta-minus (β-) decay or electron capture.

The band of stability on a plot of neutrons vs protons represents the stable isotopes that exist naturally on Earth.

Isotopes that lie above this band have an excess of neutrons or protons and are typically unstable. These isotopes tend to decay in order to reach a more stable state.

Beta-minus decay occurs when a neutron in the nucleus converts into a proton and releases an electron and an antineutrino.

This process reduces the number of neutrons in the nucleus and increases the number of protons, moving the isotope closer to the band of stability.

Electron capture occurs when a nucleus captures an electron from an electron shell and combines it with a proton to form a neutron and a neutrino.

This process also reduces the number of protons in the nucleus and moves the isotope closer to the band of stability.

Other types of decay, such as alpha decay or beta-plus (β+) decay, may also occur for isotopes above the band of stability, depending on the specific properties of the isotope.

The light bulb will take approximately 2.9 x 10² seconds to consume 2.30 x 10² joules of energy.

To calculate the time it takes for the light bulb to consume a given amount of energy, we can use the formula:

Time (in seconds) = Energy Consumed / Energy Consumption Rate

Given that the energy consumption rate of the light bulb is 80.0 joules per second, and we want to find the time it takes for the light bulb to consume 2.30 x 10² joules of energy, we can substitute these values into the formula:

Time = (2.30 x 10² joules) / (80.0 joules per second)

Time = 2.875 x 10² seconds

Explanation:

The image represent in malleable property of metal.

The image possibly represents the photoelectric effect of a metal, which is when it emits electrons after being exposed to electromagnetic radiation. Metals are also characterized by physical properties such as conductivity, malleability, metallic luster, and metallic bonding.

Based on your question, the image possibly represents the photoelectric effect, a key property of metals. This phenomenon occurs when a metal surface exposed to electromagnetic waves of a certain frequency absorbs radiation and emits electrons. These emitted electrons are called photoelectrons. Metals can also exhibit free electron model behavior, where electrons freely roam within the metal structure.

Metals possess unique physical properties like conductivity, malleability, and metallic luster. Malleability refers to the metal's ability to deform without breaking, while conductivity refers to the metal's ability to transfer heat or electricity. A metallic luster gives metals their characteristic shiny appearance.

Finally, metals are also known for their metallic bonding—a unique force that holds together the atoms within a metallic solid. Metallic bonding gives rise to many useful and varied bulk properties of metals.

Answer:

The atomic number or nuclear charge number (symbol Z) of a chemical element is the charge number of an atomic nucleus. For ordinary nuclei, this is equal to the proton number (np) or the number of protons found in the nucleus of every atom of that element. The atomic number can be used to uniquely identify ordinary chemical elements. In an ordinary uncharged atom, the atomic number is also equal to the number of electrons.

For an ordinary atom, the sum of the atomic number Z and the neutron number N gives the atom's atomic mass number A. Since protons and neutrons have approximately the same mass (and the mass of the electrons is negligible for many purposes) and the mass defect of the nucleon binding is always small compared to the nucleon mass, the atomic mass of any atom, when expressed in unified atomic mass units (making a quantity called the "relative isotopic mass"), is within 1% of the whole number A.

The maximum amount of NaCl that can dissolve in 200 mL of water at 30°C is 7.2 grams. It is important to note that this value may vary depending on the solubility of other solutes in the water, as well as factors such as pressure and the presence of other substances in the solution.

.Solubility is defined as the maximum amount of solute that can dissolve in a given amount of solvent at a specific temperature and pressure.
To determine the solubility of a solute, we can consult a solubility chart or database, which provides information on the solubility of different substances in water at different temperatures. For example, if we were to look up the solubility of sodium chloride (NaCl) in water at 30°C, we would find that it is approximately 36 grams per 100 mL of water.

Using this information, we can calculate the maximum amount of NaCl that can dissolve in 200 mL of water at 30°C. First, we convert 200 mL to 2/5 of 1000 mL, which is equivalent to 0.2 L. Then, we multiply the solubility of NaCl in water at 30°C (36 grams/100 mL) by the volume of water (0.2 L) to get the maximum amount of NaCl that can dissolve in 200 mL of water at 30°C:
36 g/100 mL x 0.2 L = 7.2 g

Answer:

The correct answer is 10.676 amu.

Explanation:

Based on the given information, the concentration of 10B left in the sample is 33.36%. Therefore, the percentage of 11B present will be,

11B = 100% - 33.36% = 66.64%

Now the atomic weight of the new boron element can be determined by adding the atomic masses of both the isotopes multiplied by its percentage.

Therefore,

= (10.013 amu * 33.36%) + (11.009 amu * 66.64%) / 100

= 10.676 amu
