The orbital diagram above is from the element ?

Chemistry
1 answer:
Anuta_ua [19.1K]3 years ago
7 0

Answer:

Phosphorus

Explanation:

In given diagram there are 15 electrons are present. Which means it is orbital diagram of phosphorus.

The atomic number of phosphorus = 15

Number of electrons = 15

Electronic configuration of phosphorus:

P₁₅ = 1s² 2s² 2p⁶ 3s² 3p³

All other options are incorrect because:

Calcium have 20 electrons.

Electronic configuration of Ca:

Ca₂₀ = 1s² 2s² 2p⁶ 3s² 3p⁶ 4s²

Hydrogen have one electron.

Electronic configuration of H.

H₁  = 1s¹

Magnesium have 12 electrons:

Electronic configuration of Mg:

Mg₁₂ = 1s² 2s² 2p⁶ 3s²

My name is Ann [436]

Answer:

A.) Absorb and store

Explanation:

The reaction for photosynthesis is:

6CO_{2}+ 12H_{2}  O → C_{6} H_{12} O_{6}  +6H_{2} O  (reaction conditions: light and chlorophyll)

<em>carbon dioxide + water → glucose + water</em>

<em />

This means light energy is <u>absorbed</u> and <u>stored</u> as sugar molecules and energy for the plant

Therefore, the photosynthesis reaction will <u>  absorb  </u> energy and <u>  store  </u> it in the chemical bonds.

The sink-float method is often used to identify the type of glass material found at crime scenes by determining its density.
Olegator [25]

Answer:

<em><u>Glass that will sink</u></em>

  • alkali zinc borosilicate with a density of 2.57 g/mL in a solution with a density of 2.46 g/mL

  • potash soda lead with a density of 3.05 g/mL in a solution with a density of 1.65 g/mL

<em><u>Glass that will float</u></em>

  • soda borosilicate with a density of 2.27 g/mL in a solution with a density of 2.62 g/mL

  • alkali strontium with a density of 2.26 g/mL in a solution with a density of 2.34 g/mL

<em><u>Glass that will not sink or float</u></em>

  • potash borosilicate with a density of 2.16 g/mL in a solution with a density of 2.16 g/mL

Explanation:

Density is the property of matter that states the ratio of the amount of matter, its mass, to the space occupied by it, its volume.

So, the mathematical expression for the density is:

  • density = mass / volume

By comparing the density of a material with the density of a liquid, you will be able to determine whether object will float, sink, or do neither when immersed in the liquid.

The greater the density of an object the more it will try to sink in the liquid.

As you must have experienced many times an inflatable ball (whose density is very low) will float in water, but a stone (whose denisty is greater) will sink in water.

The flotation condition may be summarized by:

  • When the density of the object < density of the liquid, the object will float
  • When the density of the object = density of the liquid: the object will neither float nor sink
  • When the density of the object > density of the liquid: the object will sink.

<em><u>Glass that will sink</u></em>

  • alkali zinc borosilicate with a density of 2.57 g/mL in a solution with a density of 2.46 g/mL, because 2.57 > 2.46.

  • potash soda lead with a density of 3.05 g/mL in a solution with a density of 1.65 g/mL, because 3.05 > 1.65.

<u><em>Glass that will float</em></u>

  • soda borosilicate with a density of 2.27 g/mL in a solution with a density of 2.62 g/mL, because 2.27 < 2.62.

  • alkali strontium with a density of 2.26 g/mL in a solution with a density of 2.34 g/mL, because 2.26 < 2.34.

<em><u>Glass that will not sink or float</u></em>

  • potash borosilicate with a density of 2.16 g/mL in a solution with a density of 2.16 g/mL, because 2.16 = 2.16

Which of the following should have the largest Henry's law constant (kH) in water?
Ostrovityanka [42]

Answer: Option (B) is the correct answer.

Explanation:

It is known that Henry's law is a relation between the concentration of a gas in a liquid (solubility) and the pressure it exerts on the surface of the liquid.

According to Henry's law, the pressure of a gas is directly proportional to the solubility of the gas in a liquid.

Henry's constant is represented by the symbol K_{H}. And, mathematically it is represented as follows.

                      P = K_{H}C  

where,      P = pressure and C = solubility

As the pressure for the given species is the same. Hence, the standard values of solubility of the given species is as follows.

               Gas           Solubility

                Ar          3.025 \times 10^{-5}

               CO         2.095 \times 10^{-5}

               Xe         10.519 \times 10^{-5}

            CH_{3}CH_{3}   4.556 \times 10^{-5}

              CO_{2}   8.21 \times 10^{-4}

As, Henry's constant is inversely proportional to the solubility. Hence, more is the value of solubility lesser will be the value of Henry's constant.

Thus, we can conclude that out of the given options CO have the largest Henry's law constant (K_{H}) in water.
