It is B balance, because it has a 0,01 g divisions scale. The minimun division in A balance is only 0,1 g, i.e, decigram measurement.
Answer:
A five-sided polygon.- cyclopentane
A square.- cyclobutane
A five-sided polygon with one line extending from a point.- methylcyclopentane
A 6-sided polygon with a line extending from one point to a C H 3.- methlcyclohexane
Explanation:
Answer: Compound
Explanation:
Copper(II) oxide or cupric oxide is the inorganic compound with the formula CuO. A black solid, it is one of the two stable oxides of copper, the other being Cu₂O or copper(I) oxide. As a mineral, it is known as tenorite.
<u>Answer:</u> The ion formed by lithium element is 
<u>Explanation:</u>
Ions are formed when an atom looses or gains electrons.
If an atom gains electrons, it leads to the formation of negative ions known as anions. For Example: Fluorine gains 1 electron to form 
ions.
If an atom looses electrons, it leads to the formation of positive ions known as cations. For Example: Sodium looses 1 electron to form 
ions.
Lithium is the 3rd element of the periodic table having 3 electrons.
The electronic configuration of lithium element = 
This element will loose 1 electron to attain stable electronic configuration and will lead to the formation of ion.
Hence, the ion formed by lithium element is
Answer:
Li-F
Explanation:
Hydroxide is a negative ion, which can form ionic bonds with metals, but the bond in hydrogen and oxygen in hydroxide (OH-) is not ionic. It is covalent in nature.
C-C is clearly a covalent bond.
Li-F is an ionic bond.
Bond between H and Cl in H-Cl is covalent in nature. Because of the size difference hydrogen can not act as a cation. So it rather dissociates.
