Arrange the following measurements, in seconds, from the greatest bias to the least bias. 6.63 ± 0.01 s, 6.6 ± 0.1 s, 6.52 ± 0.05 s, 6.4 ± 0.5 s

The electron is the primary atomic particle that determines an atom's chemical behaviour.

Electrons are negatively charged particles that form electron shells or energy levels around an atom's nucleus. They are engaged in the production and breaking of chemical bonds, hence they play an important part in chemical reactions.

The quantity and configuration of electrons in an atom's outermost energy level (valence electrons) are very significant in determining the chemical characteristics of the atom. Because of the identical number of valence electrons, elements in the same group or column of the periodic table frequently show similar chemical behaviour.

Final answer:

Water helps in maintaining temperature in cells due to its high heat capacity. This property allows water to absorb or release a large amount of heat without significantly changing its own temperature. As such, cells can keep a stable temperature despite environmental changes.

Explanation:

Water has a high heat capacity, which is the amount of heat it takes to change its temperature. Due to this high heat capacity, it can absorb or release a large amount of heat without a significant change in its own temperature. This helps cells maintain a relatively stable temperature and protect biological processes. For instance, when the external environment is hot, cells can avoid getting overheated as the water in them absorbs and distributes the heat evenly. Similarly, if the environment is cold, the water in the cells releases heat which helps to keep them warm. Hence, regardless of the temperature changes in the environment, the high heat capacity of water aids cells in preserving a relatively even temperature.

Answer:

4) titration

Explanation:

Titration is a standard process used in a laboratory to determine the concentration of an unknown analyte. A titrant of known concentration is gradually added to a known volume of the analyte in the presence of a suitable indicator. The end of the titration is marked by a color change of the analyte.

The given example is that of an acid(HBr) - base(NaOH) titration which can be represented by the following equation:

NaOH + HBr → NaBr + H2O

Thus  1 mole of acid gets neutralized by 1 mole of the base to form 1 mole of the salt (NaBr)

Let M1 and V1 are the molarity and volume of the base (NaOH). Here, the molarity of NaOH is known = M1 =  0.10 M and the volume, V1 corresponds to the end point in the titration.

M2 and V2 are the molarity and volume of HBr. Here, V2 is  known whereas M2 needs to be determined.

Based on the reaction stoichiometry:

moles of NaOH = moles of HBr
