The melting point for ice is at 32 degrees <span>Fahrenheit or O degrees Celsius.</span>
Answer:
See explanation and image attached
Explanation:
The IUPAC system of nomenclature enables the structure of molecules to be written seamlessly from the name of the compound. Hence it is commonly called the systematic nomenclature.
The parent chain here is propane. It is substituted at the 2- position by a methyl group and at the 3-position by 4-chlorophenyl group as we can see in the image attached to this answer.
Answer:
meander
Explanation:
A meander is the the “winding” shape that a river can take. It is is one of a series of regular sinuous curves, bends, loops, turns, or windings in the channel of a river, stream, or other watercourse(wikipedia).
A meander is formed when water in the river erodes the banks just outside its channel. The water then deposits some sediments inside the channel.
Answer:
<h2>Volume = 6 cm³</h2>
Explanation:
Density of a substance is given by
From the question
Density = 4.0 g/cm³
mass = 24g
Substitute the values into the above formula and solve for the volume
That's
Divide both sides by 4
v = 6
We have the final answer as
<h3>Volume = 6 cm³</h3>
Hope this helps you
Electrons in an atom can be classified as core electrons and valence electrons. Valence electrons are those electrons which are present in valence shell and participates in bond formation. While, Core electrons are all remaining electrons which are not present in valence shell, hence not take part in bonding.
Atomic number of Selenium (Se) is 34 hence it has 34 electrons with following electronic configuration;
1s², 2s², 2p⁶, 3s², 3p⁶, 4s², 3d¹⁰, 4p⁴
From electronic configuration it is found that the valence shell is 4, and the number of electrons present in valence shell are 6. So,
Core Electrons = Total Electrons - Valence Electrons
Core Electrons = 34 - 6
Core Electrons = 28
Result:
There are 28 core electrons in Selenium.
