Answer:
The glasses with different amounts of water make different sounds. ... This is because the empty glass only has air around it, so the glass vibrates quickly when it is hit, causing the high pitch sound. The glass full of water causes the glass to vibrate slower, and the sound you hear is at a lower pitch.
Explanation:
Covalent Bonding
Ionic bonds are characterized by a transfer of electrons between elements to form a stable compound. These bonds typically form in compounds consisting of a metal and a nonmetal, which are positively and negatively charged respectively.
Covalent bonds are characterized by a sharing of electrons between the elements in the compound. Covalent bonds are formed between nonmetals and in many inorganic compounds as well.
Metallic bonding, as the name suggests, is formed between metals.
Since phosphorus pentoxide consists of 4 phosphorus atoms and 10 oxygen atoms, and both of which are categorized as nonmetals, phosphorus pentoxide is therefore, bonded covalently.
Units are all fine. No need of conversion.
Just Use the formula:
V = mass / density
V = 76.2 / 13.6 = 5.6 mL
The graph of the relationship between the volume and temperature of an enclosed gas is ; ( A ) It is a straight line with a positive slope showing that an increase in temperature results in an increase in volume
According to Charlies' law at constant pressure, the volume of a gas ( enclosed gas ) is directly proportional to it's temperature ( kelvin temperature ) given that the amount of the enclosed gas is kept constant.
Therefore the graph showing the relationship between the volume and temperature will be an straight line and the slope will be a positive slope.
Hence we can conclude that The graph of the relationship between the volume and temperature of an enclosed gas is a straight line with a positive slope showing that an increase in temperature results in an increase in volume

Explanation:
The condensed formula of a molecule is the formula where the symbols of atoms are listed in order as they appear in the molecule's structure with bond dashes omitted or limited.
The structural formular however, showed how the atoms are connected.
The condensed formular is given as; HOCH2COCH2OH
The condensed formular was gotten by writting out the elemnts in the order that they appear in.
The stuctural formular is shown in the attachement.
