Answer:
Temperature. Heating up the solvent gives the molecules more kinetic energy.
Explanation:
The more rapid motion means that the solvent molecules collide with the solute with greater frequency and the collisions occur with more force. Both factors increase the rate at which the solute dissolves. hope this helps you :)
Explanation:
According to the electronegativity table, whenever there a difference of more than 2.0 then the bond formed will be ionic in nature. On the other hand, if electronegativity difference is less than 0.5 then the bond formed will be non-polar covalent in nature.
As it if given that electronegativity difference of given elements will be as follows.
Electronegativity difference = 3.1 - 0.9
= 2.2
Since, the electronegativity difference of given elements is 2.2. Hence, these elements will form an ionic bond.
Thus, we can conclude that mostly ionic in character and formed between a metal and non-metal best describes the bond between these elements.

Classify the following elements into metals, nonmetals, metalloids, or gases, noble
: fluorine, sulfur, nitrogen, chlorine, magnesium, helium, sodium, bromine, silicon, tellurium.
- Metals: magnesium and sodium.
- Nonmetals: fluorine, chlorine, bromine, sulfur and nitrogen.
- Metalloids: silicon and tellurium.
- Noble gases: helium.
Explanation:
Metals: They occupy the left and central areas of the Periodic Table; therefore, they constitute a majority group of the elements.
Nonmetals: They are located in the upper right region of the Periodic Table.
Within the Periodic Table, the metalloids lie diagonally from boron to polonium. Items above on the right are nonmetals, and items below on the left are metals.
The noble gases are located in group 18 of the Periodic Table.
Answer:
Water acts as a solvent of carbon dioxide excreted from tissues, in blood and helps in regulating pH (because it forms carbonic acid that lowers pH when it tends to get higher). Blood pH should be maintained at about 7.4. One major reason is that the structure of protein is dependent ton pH because pH determines its ionization hence also affecting the charges and interaction between side groups of amino acids. A change in pH may, therefore, denature proteins and negatively affect cellular functions.
