How can you explain the similarities between alcohol molecules and water molecules?
Actually, both are same. Both can form in liquid state at room temperature. Both alcohol molecules and water molecules contain H and O . Both are compounds ,different types of atoms. Both are formed from covalent bonds and non metals. For further explanation water molecules hold hydroxyl groups that can form hydrogen bonds with water molecules and with alcohol molecules. And alcohol molecules can form hydrogen bonds with other alcohol molecules such as with water. As alcohol form hydrogen bonds with water and tend to be relatively soluble in water. The hydroxyl group is referred to as a hydrophilic group, because it forms hydrogen bonds with water and increase the solubility of an alcohol in water.
Which of a hydrogen filled balloon air filled balloon and a carbon dioxide filled balloon will deflate the fastest and which is the slowest and explain your answer?
A hydrogen balloon will deflate the fastest because molecules of hydrogen are the smallest and thus will more easily slip through the latex of the balloon. The carbon dioxide-filled balloon will deflate the slowest because these molecules are the biggest, and thus will have more trouble escaping the tiny pores in the balloon.
Water molecules have a polarity which allows them to be electrically attracted to other water molecules and other polar molecules by weak chemical bonds known as?
Hydrogen bonding. Water molecules electrons are not sharred evenly between the hydrogen and oxygen atoms. The easiest way to explain it is that the oxygen atom "hogs" the electrons. Since it has 8 protons in it's nucleus the oxygen has a greater pull. Hence the oxygen is slightly negative (negative charge of electrons) and ther hydrogen side has a slightly positive charge. Hydrogen bonding is part of the category known as Van Der Wall forces. Basically, the hydrogen part of the water molecule bonds with a slightly negative part of another molecule. This allows for adhesive and cohesive bonding cababilities of water.
Explain why ammonia is a compound?
Ammonia (NH3) consists of molecules of two different elements, nitrogen and hydrogen, bonded together. Since it consists of atoms of more than one element chemically bonded, it is a compound.
The of water molecules and the hydrogen bonds between water molecules explain most of the waters life supporting properties?
Water is a polar molecule with several unique properties: its high specific heat, the high heat of vaporization, the process of evaporative cooling, and it's strong surface tension are all emergent from the formation of hydrogen bonds.
What do yo mean by neighbouring group effect explain?
the neighbouring group mechanism
What happens when many water molecules come into contact with one another Explain?
they form hydrogen bonds
What contains water molecules and the hydrogen bonds between water molecules explain most of water's life-supporting properties?
I'm pretty sure it's Hydrogen Bonding. :) -K.

How atom and molecules are important to cell processes explain?

What is a unique property of water Describe the property and explain the chemical or physical reason that causes water to have the property?
Hydrogen bonding causes water molecules to connect . The energy required to break multiple hydrogen bonds causes water to have a high heat of vaporization; that is, a large amount of energy is needed to convert liquid water, where the molecules are attracted through their hydrogen bonds, to water vapor, where they are not.
Did Bohr's model of the atom explain hydrogen's flammability?
Bohr's model of the atom doesn't explain hydrogen's flammability.

H3PO4 which contains three hydrogen atoms per molecule is a weak acid whereas HCl only contains one hydrogen atom per molecule is a strong acid explain why?
The strength of an acid depends upon its ability to donate the H+ ions in aqueous solution, phosphoric acid dissociates about 5% that means 5 out of 100 molecules become ionized, 5 molecules of this acid may produce 5 x 3 = 15 hydrogen ion per 100 molecules, while HCl dissociates about 98% so 98 hydrogen ions are produced by 100 molecules of HCl so it is strong acid.
how do you explain what polar molecules are?
Water molecules are polar molecules. Both of the bonds inside the molecule are polar bonds.
When you are building molecules using the models explain WHY carbon has 4 projections places for bonds oxygen has 2 projections and hydrogen has one projection?
Projection symbolize a bond.Number of bonds can be formed depend on valency.Hydrogen can form a single bond only..It raise Hydrogen into nobel gas state.
