Molecular compounds boil at much higher temperatures than do ionic compounds true or false?
This is false. Ionic compounds have higher boiling points than molecular compounds. For example, the boiling point of the ionic compounds copper(II) oxide, CuO, and sodium chloride, NaCl are 2,000 degrees C and 1,413 degrees C, respectively. The boiling point of the molecular compounds carbon tetrachloride, CCl4, and water, H2O are 76.72 degrees C and 100 degrees C, respectively.
True or false Low melting points and lack of eletrical conductivity are properties of molecular compounds?
True. Molecular compounds have low melting points because their intermolecular forces are weaker compared to ionic or metallic compounds. They also do not conduct electricity well because they lack free-moving charged particles.
Lipids are water avoiding or hydrophobic compounds is true or fals?
True. Lipids are hydrophobic compounds that do not mix well with water.
What does it mean when a solution is being neutral?
true
Are metals able to form ionic bonds with nonmetal's true or false?
Yes, ionic bonds typically form between metals and nonmetals because the electronegativity difference between these types of elements is usually large.
True or false ionic compounds such as sodium chloride dissolve easily in water?
True
True or false binary ionic compounds consist of two metal elements?
True
It is true for all compounds Composition of ionic compounds Which is NOT true of compounds Which is?
The statement that all compounds have a composition of ionic compounds is false. Many compounds can be covalent in nature, where atoms share electrons instead of transferring them. On the other hand, it is true that compounds have a definite composition with fixed ratios of elements and compounds are formed by the bonding of two or more different elements.
Carbon can only form ionic compounds true or false?
False. Carbon can form both ionic and covalent compounds. Carbon typically forms covalent bonds due to its ability to share electrons with other elements.
An ionic compound is made of a nonmetal and a metal true or false?
True. Ionic compounds form between a metal and a nonmetal. The metal loses electrons to become a cation (positively charged ion), while the nonmetal gains these electrons to become an anion (negatively charged ion).
Dipole attraction form bonds in an aqueous solution of ionic compounds true or false?
True. In an aqueous solution of ionic compounds, the positive and negative ions will attract each other due to their opposite charges, forming electrostatic bonds known as dipole attractions.
Is it true or false that binary ionic compounds are composed of metal and nonmetals typically from opposite sides of the periodic table?
True. Binary ionic compounds consist of a positively charged metal ion and a negatively charged nonmetal ion. These ions usually come from opposite sides of the periodic table.
Is it true or false that the crystal lattice of ionic compounds affects their melting and boiling points?
True. The crystal lattice structure of ionic compounds plays a significant role in determining their melting and boiling points. The stronger the forces holding the ions in the lattice together, the higher the melting and boiling points of the compound.
Molecular compounds boil at much higher temperatures than do ionic compounds true or false?
This is false. Ionic compounds have higher boiling points than molecular compounds. For example, the boiling point of the ionic compounds copper(II) oxide, CuO, and sodium chloride, NaCl are 2,000 degrees C and 1,413 degrees C, respectively. The boiling point of the molecular compounds carbon tetrachloride, CCl4, and water, H2O are 76.72 degrees C and 100 degrees C, respectively.
True or false in naming the ionic compounds the cation is always named first and the anion second?
True. In naming ionic compounds, the cation (positively charged ion) is always named first followed by the anion (negatively charged ion). This convention helps identify the elements and their charges in the compound.
Most salts are binary ionic compounds. A. True?
True. Most salts are binary ionic compounds composed of a cation from a metallic element and an anion from a nonmetallic element.
A single unit of an ionic compound is referred to as a molecule?
Actually, a single unit of an ionic compound is referred to as a formula unit. Unlike molecules, ionic compounds do not exist as discrete molecules but as an arrangement of ions in a crystal lattice.
