Explanation:
Hello,
In this case, since one drop equals 0.05 mL of the given solution, for a concentration 0.02 g/mL, the grams of oleic acid in one drop turns turn out:
Best regards.
To determine the expected pH of the resulting solution of the following substances, create a balanced chemical equation of their ionization in water:
HI
HI + H2O ---> H+ + I-
It completely dissociates into H+ and I-. Due to the presence of the Hydronium Ion, the solution is acidic.
KBr
KBr + H2O ----> HBr + KOH
The salt KBr is formed by a strong base and a weak acid, therefore, the solution it forms with water is basic.
LiOH
LiOH + H2O ----> Li+ + OH-
It dissociates completely in water, turns into Li+ and OH-. Due to the presence of Hydroxide Ion, the solution becomes basic.
Answer:
the number of protons in the nucleus of an atom, which is characteristic of a chemical element and determines its place in the periodic table.
atomic number, the number of a chemical element in the periodic system, whereby the elements are arranged in order of increasing number of protons in the nucleus. Accordingly, the number of protons, which is always equal to the number of electrons in the neutral atom, is also the atomic number. An atom of iron has 26 protons in its nucleus; therefore the atomic number of iron is 26.

Some can, yes. It uses ATP I think
It is true that the iron recommendation for girls exceeds that of boys during adolescence.
During an adolescence, girls and boys require iron for a large growth spurt and the gain of adult phenotypes and biologic rhythms.
In this period of the life, iron recommendation increase in both girls and boys, because of the increase in lean body mass, the expansion of the total blood volume, the increase and start of menstruation at girls.
Iron is essential for oxygen transport, red blood cell creation, cognitive performance and immunological function.
The overall iron requirements for girls are up to twice as boys.
