Answer:
Bar graphs have an x-axis and a y-axis like most bar graphs, like the one above, the x-axis runs horizontally (flat).
Sometimes bar graphs are made so that the bars are sidewise like in the graph below. Then the x-axis has numbers representing different time periods or names of things being compared.

-Hops
It depends on mass and velocity.
In this case as the ice is solid its particles are stationary that it have zero velocity hence its kinetic energy is too zero.
Answer:option a
Answer:
A. Law of constant composition or definite proportion
B. Law of conservation of mass
C. Law of multiple proportion
Explanation:
A. The law of constant composition states that "all pure samples of the same chemical compound contain the same proportion of the elements by mass". Considering the pure same of KCl obtained from different locations, their samples regardless of the procedure used to make them or geography wil be in the same proportion when analysed.
B. Law of conservation of mass states that "mass can neither be created nor destroyed". This law applies to all chemical reactions in which matter is only changed from one form to another. In the bulb, magnessium and oxygen merely combines to magnessium oxide. No loss of matter.
C. Law of multiple proportion states that "when two elements combine to form two or more different compounds, the masses of one of the elements which seperately combine with a fixed mass of the other element are in a simple ratio ".
Answer:
See answer below
Explanation:
This is pretty easy to solve. First you need to understand that an ionic compound is usually formed between a metal and a non metal. This usually happens between elements from group 1 through group 10 or 11 of the periodic table. A covalent compound is always given in non metal elements from the periodic table, and it's usually the elements from group 13 through group 17.
Some compounds there are missing some atoms, but I manage to find this question and saw the atoms missing, so, in my answer you will see the corrected compound. so don't be surprised.
According to what I state above, then the covalent compounds are:
C₆H₅N
PCl₃
C₂H₄O
NH₃
N₂
SO₄²⁻
The ionic compounds are:
CaO
CdBr₂
WO₂
Na₂O
CsF
Hope this helps
