Oil spills happen when people make mistakes or are careless and cause an oil tanker (a ship that carries oil from one country or place to another) to leak oil into the ocean. ... Natural disasters (like hurricanes) may cause an oil spill, too, by flipping an oil tanker over, causing oil to come pouring out.

An oil spill is the release of a liquid petroleum hydrocarbon into the environment, especially the marine ecosystem, due to human activity, and is a form of pollution. The term is usually given to marine oil spills, where oil is released into the ocean or coastal waters, but spills may also occur on land.

A release of oil into the environment, either leaked or discharged from a ship, lorry, truck etc
The major environmental impacts so far have come from normal activities, rather than catastrophic oil spills.
Or
an accidental release of oil into a body of water, as from a tanker, offshore drilling rig, or underwater pipeline, often presenting a hazard to marine life and the environment.

The image shows the representation of an unknown element in the periodic table.
Mademuasel [1]

Answer is: The sum of the masses of protons and neutrons is 20.1797.

This element (neon) has atomic number (Z) 10, which means it has 10 protons and 10 electrons.

Atomic number (Z) is the number of protons, which is characteristic of a chemical element.

Atomic mass (A) is 20.1797.

Ar is relative atomic mass (the ratio of the average mass of atoms of a chemical element to one unified atomic mass unit) of an element .

Which statement describes why sodium reacts more vigorously than magnesium to hydrochloric acid? Refer to the periodic table. Ci
lions [1.4K]

Sodium has a lower ionization energy than magnesium describes why sodium reacts vigorously than magnesium chloride.

<h3>Why is sodium more reactive than magnesium?</h3>
  • Sodium is more reactive than magnesium because it has the ability to easily lose electron, hence have lower ionization energy.
  • Sodium belong to group one on the periodic table and they are called akali metal while magnesium belong to group two on the periodic table and they are called alkali Earth metal.

  • Sodium and magnesium belong to the in the 3rd period. Iin the outermost energy level sodium has one electron but magnesium has 2 electrons. Therefore, there is more attraction abetween the nucleus and electrons in magnesium than that of sodium.

Therefore, sodium is more reactive than magnesium chloride because of lower ionization energy.

For more details on sodium reactivity, check the link below.

Determine the chemical formula for the compound, tetracarbonylplatinum(iv) chloride. [pt(co)4cl4] 2- [ptcl4](co)4 [pt(co)4]cl4 [
shusha [124]
Analyze the Name of complex Compound.

                              T<span>etracarbonylplatinum(iv) chloride

So, there are,
                               4 Carbonyl groups = 4 CO = (CO)</span>₄
                               1 Platinum Metal    = 1 Pt  = Pt
                               Unknown Chloride atoms = ?
In complexes positive part is always named first, so the sphere containing Pt and carbonyl ligands is written first,

                                     [Pt (CO)₄]

The charge on sphere is +4 because CO ligand is neutral, and Pt has a Oxidation state of four as written in name (IV),
So,
                                             [Pt (CO)₄]⁴⁺

Now, in order to neutralize +4 charge we should add 4 Chloride ions, So,

                                            [Pt (CO)₄] Cl₄
