What characteristic of o2 is correct?
Oxygen is a colorless, odorless and tasteless gas. It will support life. It is noncombustible, but will actively support the burning of combustible materials. Some materials that will not burn in air will burn in oxygen.
Which is a characteristic of hydrophobic molecules which is a characteristic of hydrophobic molecules?
Which is a characteristic of hydrophobic molecules? They have very few or no polar covalent bonds.
Which parts of atoms can interact react to form chemical bonds?
Which parts of atoms can interact (react) to form chemical bonds? valence electrons; Only the outermost parts of atoms interact (react) with each other, and those are the valence electrons. If the outermost orbital is full, the atom is stable and less likely to react with another atom.
Which functional group can accept protons?
Classifications by Reaction Types. The rationale of classification by reaction types is that different functional groups may show the same kinds of reactions. Thus, as we have just seen, alcohols, carboxylic acids, and amines all can accept a proton from a suitably strong acid.
Are hydrogen bonds important for holding large molecules together?
Hydrogen bonds are important for holding large molecules together. Hydrogen bonds are strong attractive forces between hydrogen atoms and negatively charged atoms. Hydrogen bonds can occur within a single molecule. Hydrogen bonds are responsible for many of the properties of water.
Why is wax hydrophobic chemistry?
Waxes. Waxes are similar to fats except that waxes are composed of only one long-chain fatty acid bonded to a long-chain alcohol group attached. Because of their long, nonpolar carbon chains, waxes are extremely hydrophobic (meaning they lack an affinity for water).
In what way is the sodium ion different from the sodium atom?
Sodium atom is neutral whereas sodium ion is a charged specie with a charge of +1. The number of protons and electrons in sodium atom is same i.e 11 whereas the number of protons in sodium ion (11) is more than number of electrons (10). The size of sodium ion is smaller than sodium atom.
Which functional groups behaves as bases?
Amino groups can also act as bases, which means that the nitrogen atom can bond to a third hydrogen atom as shown in the image below. Once this occurs, the nitrogen atom gains a positive charge and can now participate in ionic bonds. The amine functional group can exist in a deprotonated or protonated state.
Is hydrogen a functional group?
While the majority of functional groups involve atoms other than carbon and hydrogen, we will also look at some that include only carbon and hydrogen. Some of the most common functional groups are presented in the following sections.
Why is sodium considered to be a reactive metal?
In other words, more reactive metals will have a low IE. So, the short answer to your question is that sodium (and the other alkali metals) are so reactive because they lose their valence electron very easily. To understand why these metals have this property requires us to look at the characteristics of their atoms.
Why are lithium, sodium and potassium all alkali metals?
Simply because they have the same no of valence electrons and show similar chemical properties, Chemical properties in the sense how we predict an element will react with other matter (the valence electrons which determines its reactivity) Because they are all Alkali metals with analagous properties and because the a have a single valency electron.
Which is an alkaline metal on the periodic table?
Here’s the definition for alkaline metals: any of the elements Lithium, Sodium, Potassium, rubidium, cesium, and francium, occupying Group IA (1) of the periodic table. They are very reactive, electropositive, monovalent metals forming strongly alkaline hydroxides.
Why are lithium and beryllium atoms in the same row?
A neutral lithium atom has 3 electrons, a neutral beryllium atom has 4 electrons, and so on. With each extra electron, the negative charge of the electron cloud increases. What you’re not doing is increasing the number of energy levels. For every element on the same row, the electrons are organized into the same number of energy levels.
