The right answer is polarity.
In chemistry, polarity is a characteristic describing the distribution of negative and positive charges in a dipole. The polarity of a bond or a molecule is due to the difference in electronegativity between the chemical elements that compose it, the differences in charge that it induces, and to their distribution in space. The more the charges are distributed asymmetrically, the more a bond or molecule will be polar, and conversely, if the charges are distributed in a completely symmetrical manner, it will be apolar, that is to say non-polar.
Polarity and its consequences (van der Waals forces, hydrogen bonding) affect a number of physical characteristics (surface tension, melting point, boiling point, solubility) or chemical (reactivity).
Many very common molecules are polar, such as sucrose, a common form of sugar. The sugars, in general, have many oxygen-hydrogen bonds (hydroxyl group -OH) and are generally very polar. Water is another example of a polar molecule, which allows polar molecules to be generally soluble in water. Two polar substances are very soluble between them as well as between two apolar molecules thanks to Van der Waals interactions.
Answer:
0.1m/s
Explanation:
The speed, which refers to how fast an object moves within a period of time, can be calculated as follows:
Speed (m/s) = distance (m)/time (s)
Based on the provided information in the question, distance = 10m, time = 100s
Hence, the speed will be:
Speed = 10/100
Speed = 0.1m/s
A. Most people thought that trillium was not getting enough sunlight in the forest.
Explanation – Scientists used to believe that the population of trillium decreased because there were not enough sunlight to reach these plants. Later, it was found that deer used to eat the flowers of trillium plant that led to the decrease of its population.
The seed of the trillium plant is very nutritious and hence consumed by the deer. Because of this, trilliums were found to be unlikely to recolonize local areas on their own.
