M(AgNO₃) = 169.9 g; mass.
n(AgNO₃) = m(AgNO₃) ÷ M(AgNO₃).
n(AgNO₃) = 169.9 g ÷ 169.87 g/mol.
n(AgNO₃) = 1 mol; amount of silver nitrate.
c(AgNO₃) = 1 M = 1 mol/L.
V(AgNO₃) = n(AgNO₃) ÷ c(AgNO₃).
V(AgNO₃) = 1 mol ÷ 1 mol/L.
V(AgNO₃) = 1 L.
V(AgNO₃) = 1 L · 1000 mL/L.
V(AgNO₃) = 1000 mL; volume of silver nitrate.
Answer: (b). Atoms transfer electrons to form cations and anions.
Explanation:
Covalent compounds are formed by sharing of electrons takes place between non metals.Ionic compounds are formed by transfer of electrons between metals and non metals.
For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.
Sodium atom has oxidation number of +1.
Electronic configuration of sodium:
Sodium atom will loose one electron to gain noble gas configuration and form sodium cation with +1 charge.
Chlorine atom has oxidation number of -1.
Electronic configuration of chlorine:
Chlorine atom will gain one electron to gain noble gas configuration and form chloride ion with -1 charge.
In sodium chloride the one electron from sodium metal gets transferred to chlorine atom and thus form an ionic bond.
Answer:
the pressure will increase
Mitosis is the reproduction of cells. There is an entire cycle of it as well! In the cycle, it has multiple phases. Prophase, Prometaphase, Metaphase, Anaphase, and Telophase.
Answer:
Explanation:
oxide or ferric oxide is the inorganic compound with the formula Fe₂O₃. It is one of the three main oxides of iron, the other two being iron(II) oxide, which is rare; and iron(II,III) oxide, which also occurs naturally as the mineral magnetite. As the mineral known as hematite, Fe₂O₃ is the main source of iron for the steel industry. Fe₂O₃ is readily attacked by acids. Iron(III) oxide is often called rust, and to some extent this label is useful, because rust shares several properties and has a similar composition; however, in chemistry, rust is considered an ill-defined material, described as Hydrous ferric oxide.
