Meg used two examples to represent two different states of matter.

torisob [31]

Answer:

c Example 1 represents a liquid and Example 2 represents a solid.

Explanation:

Example 1: Young children dancing slowly around one another

The young children dancing slowly around one another can be pictured as the flow of liquid. In liquids, the molecules are held about weakly and they slide on top of each other. They are held by weak attractive forces. This is clear picture of a liquid.

Example 2: Newborn babies sitting in their given spots in a crib

This is clear example of a solid. In a solid the molecules are held about a fixed spot. The attractive forces in liquids is very great and the molecules therein do not move about randomly.

How many oxygen (O) atoms are involved in this chemical reaction?<br><br> 2Fe(OH)3 — Fe2O3 + 3H20

kenny6666 [7]

Answer:

6 oxygen atoms

Explanation:

From the equation,

2Fe(OH)₃ → Fe₂O₃ + 3H₂O

From the reactant (left hand side) we have 2 moles of Fe(OH)₃ having (2 * 3 = 6) atoms of oxygen and decomposed to give Fe₂O₃ which contains 3 atoms of oxygen and 3 moles of water that also contains 3 atoms of oxygen.

Since the number of oxygen participating in the reaction is independent on the product (not a reversible reaction) then the total number of oxygen atoms participating in the reaction is 6

A certain compound is made up of one carbon (c) atom, two bromine (br) atoms, and one oxygen (o) atom. what is the chemical form

padilas [110]

Answer:
Chemical Formula = COBr₂

Structural Formula = Attached Below

IUPAC Name = Carbonic Dibromide

Common Name = Bromophosgene

As we know Carbon has the tendency to form four covalent bonds, Oxygen can form two covalent bonds and Bromine can form a single bond. Keeping this in mind we can say that in given compound carbon is forming two single bonds with two bromine atoms and a double bond with oxygen atom. Therefore, the valencies of all elements in the given compound are satisfied and completed.
