What genotype are the a father and mother in this Punnett square?

Explanation:

carbon dioxide is a green house gas among many others, human activities Increase the amount of co2 being released. Co2 acts as a global insulator, when the sun rays enter the atmosphere and then bounces back off the earth, the co2 creates a blanket that traps the sun rays. this therein causes the surface of the earth to "heat up" and cause global warming. the increased temperatures triggers another series of events; ice caps begin to melt and in already hot areas there are chances of forest fires etc. the melting of the ice then causes a rise in sea level and the potential release of diseases and other unknown material that was trapped in the ice from different ages ago. the rise in sea level can cause land area to decrease and small islands to be submerged. many habitats would be affected as the ice above the water acts as Insulation that keeps the water below at optimum conditions for sea creatures. on another note, the forest fires destroy habitats and property, this leads to many species becoming endangered and the environment to become inhabitable as the air is not breathable due to thick smoke etc. the fires also contribute back to the global warming and it will just get increasingly worse over a period of time if without interference. the seasons in many place will change to more rapid and serious conditions....

The structure of matter refers to its composition.

Answer:Because there are so many units for energy.

Explanation:

The correct option is D: Chemical property

Chemical properties can be observed only by changing a substance into a different substance.

When a substance or a material undergoes a chemical change then it becomes a completely different kind of substance.

In chemistry, chemical properties are the kind of properties that can be observed or measured as a result of a chemical change.

Examples of chemical changes are rusting of iron, combustion of a compound or fossil fuels, flammability, reactivity, acidity, and toxicity.

To put it simply, a chemical property brings a complete change to the identity of a matter.

Number of coulombs of positive charge in 250cm^3 water is 1.3×10^7 C

The volume of 250 cm^3 corresponds to a mass of 250 g since the density of water is 1.0 g/cm^3

This mass corresponds to 250/18 = 14 moles since the molar mass of water is 18. There are ten proton (each with charge q = +e) in each molecule of [tex]H_{2}O[/tex] So,

Q = 14NA  q =14(6.02×10^23)(10)(1.60×10^−19C) = 1.3×10^7 C.

Mass is the quantity of matter in a physical body. It is also a measure of the body's inertia, the resistance to acceleration when a net force is applied. An object's mass also determines the strength of its gravitational attraction to other bodies.

The mass percentage of each compound in the mixture is as follows:

mass percentage of Lithium chloride, LiCl = 14.11%

mass percentage of Lithium carbonate, Li₂CO₃ = 42.82%

mass percentage of lithium nitrate, LiNO₃ = 43.09%

The mass percentage of each compound in the mixture is calculated as follows:

Assuming the mixture consists of 1 mole of each of lithium chloride, LiCl, lithium carbonate, Li₂CO₃, and lithium nitrate, LiNO₃

Total mole of lithium = 4 moles

Total moles of oxygen = 6 moles

Total moles of Chloride = 1 mole

Total moles of Nitrogen = 1 mole

Li = 14.19 %

CI = 10.56%

C = 6.198 %

O = 59.06%

N = 10.01%

The mass percentage of each compound in the mixture will be:

mass percentage of Lithium chloride, LiCl = 14.19%/4 + 10.56% = 14.11%

mass percentage of Lithium carbonate, Li₂CO₃ = 2 * (14.19 %/4) + 6.198 % + 3 * (59.06%/6) = 42.82%

mass percentage of lithium nitrate, LiNO₃ = 14.19 %/4 + 10.01% + 3 * (59.06%/6) = 43.09%

The diameter of the nucleus in angstrom, given the data is 1×10⁻⁵ angstrom

1 nm = 10 angstrom

The following data were obtained from the question:

1 m = 1×10⁹ nm

Therefore,

1×10⁻¹⁵ m = (1×10⁻¹⁵ m × 1×10⁹ nm) / 1 m

1×10⁻¹⁵ m = 1×10⁻⁶ nm

1 nm = 10 angstrom

Therefore,

1×10⁻⁶ nm = (1×10⁻⁶ nm × 10 angstrom) / 1 nm

1×10⁻⁶ nm = 1×10⁻⁵ angstrom

Answer: 1.24 X 10-22 g. The atomic mass of arsenic is 74.92 amu, 1 mole of arsenic atom has 74.92g weight.

Explanation:

Mole measure the number of elementary entities of a given substance that are present in a given sample. Therefore, 0.602×10²³ atoms are there in 7.61 grams of arsenic.

The SI unit of amount of substance in chemistry is mole. The mole is used to measure the quantity or amount of substance. We know one mole of any element contains 6.022×10²³ atoms which is also called Avogadro number.

Mathematically,

mole =given mass ÷ molar mass

given mass of arsenic= 7.61 grams

Molar mass of 1 mole of arsenic= 74.92g/mol

substituting the given values, we get

number of mole of arsenic =7.61  ÷ 74.92g

        =0.10moles

number of atoms of arsenic= number of moles of arsenic× Avogadro number

                                              =0.10× 6.022×10²³

                                              =0.602×10²³ atoms

Therefore, 0.602×10²³ atoms are there in 7.61 grams of arsenic.

The atomic theory have been developed over the years by the works of many scientists.

The atomic theory is the series of postulations that sought to explain the behavior of the atom. The study of the atom started as far back as the time of Democritus and Aristotle.

The first empirical study of the nature of the atom started with the work of John Dalton when he proposed the famous Dalton's theory. Further empirical work was carried out by J.J Thompson which gave rise to the plum pudding model of the atoms.

The work of Ernest Rutherford introduced the planetary model of the atom which was latter replaced by the Bohr model based on energy levels. Today, the work of Erwin Schrödinger has led us to the appreciation of the wave mechanical model of the atoms which is the mot accepted model for the atom today.

The AgCl would be least soluble in 0.1M NaCl

Strength of NaCl Solution = 0.1M

K(sp) AgCl = 1.20 * 10⁻¹⁰

Let solubility of AgCl be 'x'

∴ AgCl ⇔ Ag⁺ + Cl⁻

     x           x       x

∵ NaCl is strong electrolyte and is completely ionized. It shall provide Cl⁻ ion concentration = 0.1 M

[Ag⁺] = x                   [Cl⁻] = (x + 0.1) M

K(sp) = [Ag⁺] [Cl⁻] = x * (x + 0.1) = x² + 0.1x

∵ x << 1    ∴ x² is neglected

       ∴ 1.20 * 10⁻¹⁰ = 0.1x

         ⇒ [tex]x = \frac{1.20 * 10^{-10}}{0.1} = 1.20 * 10^{-9}[/tex]

Solubility of AgCl in 0.1M NaCl = 1.20 * 10⁻⁹M

Positively charged aluminum ions gain electrons from the cathode and form molten aluminum. Electrolysis is used to perform the extraction. The aluminum oxide must let the ions to travel freely in order for electricity to flow through it.

Due to its extremely high melting point (about 2000°C), aluminum oxide would be expensive to melt. Although it doesn't dissolve in water, aluminum oxide does in molten cryolite. The melting point of this aluminum compound is lower than that of aluminum oxide. Cryolite utilization lowers some of the energy expenses associated with aluminum extraction. Carbon dioxide bubbles off once the oxygen and carbon in the electrodes react. The positive electrodes must consequently be replaced regularly since they lose carbon over time.

The atomic number, which is equal to the number of protons in the nucleus, controls the electrons in the atoms, which in turn control the chemistry.

The periodic table is all about chemistry, for one simple reason. The atomic number, which is equal to the number of protons in the nucleus, controls the electrons in the atoms, which in turn control the chemistry.

The atomic number is what distinguishes an element.

Additionally, if we have two distinct isotopes of the same element, their atom types will differ.

As a result, there is significant power in using isotopic systems that only use one element, as demonstrated by the analysis of the three oxygen isotopes (16O, 17O, 18O), which have different properties, should be treated as different types of atoms in an atoms table.

As each isotope of an element is listed as a different species, the chart of the nuclides can be thought of as a "chart of atoms."
