Explanation:
Ionization energy is defined as the energy necessary to remove an electron from a gaseous atom or ion.
Therefore, smaller is the size of an atom or ion more energy it needs to remove an electron because more is the charge on an ion smaller will be its size.
Hence, more will be the attraction between nucleus and valence electrons of the atom. So, more difficulty is faced by the atom to lose an electron. As a result, ionization energy will increase.
Across the period, there will be decrease in size of elements of the periodic table.
Thus, we can conclude that there will be increase in first ionization energy across the periodic table.
Unit cells.
They are the smallest group of atoms that take form of a crystal and can repeat in 3 dimensions.
The phenomenon known as "salting-out" occurs at very high ionic strengths, when protein solubility declines as ionic strength rises. As a result, salting out may be used to segregate proteins according to how soluble they are in salt solutions.
Because large levels of sodium chloride disturb the bonds and structure of the active site, the rate of enzyme activity will gradually decrease as the concentration of sodium chloride rises. As a result, some of the active sites get denaturized and the starch loses its ability to attach to them. As more enzymes get denatured and eventually cease to function, enzyme activity will steadily wane.
Answer:
C )
Explanation:
Controlled scientific experiment tests scientific assumption (hypothesis), under controlled conditions.
In controlled scientific experiment, alters the test variable (independent variable) and observes the effects on the outcome variable (dependent variable).
Eg : Studying impact of sunlight on plant's group, where former independent variable is altered & its effects on dependent outcome variable is observed.
Answer:
The most common reason for alloying is to increase the strength of a metal. This requires that barriers to slip be distributed uniformly throughout the crystalline grains. On the finest scale, this is done by dissolving alloying agents in the metal matrix (a procedure known as solid solution hardening
