None of these; the most electronegative element is fluorine because an atom of fluorine needs an additional electron to join it's outer membrane, so the atom can achieve stability.
a flourine atom on its own is always a negative ion.
Answer:
Picking up marbles and placing them in a sack
Explanation:
The entropy of a chemical system is defined as the measure of disorder. Therefore a negative change in entropy is the movement to a more ordered state. The only option here which achieves a more ordered state, would be the first option.
Picking up marbles and placing them in a stack achieves more order, rather than the other options - that achieve more disorder.
Answer:
A force doesn't act on another force. Forces act on objects.
"Unbalanced force" simply means that the sum of all forces acting on an object - that is, the net force - is not equal to zero.
Explanation:
Answer:
Chemical energy to heat energy
Explanation:
The type of energy conversion when fuel is burnt to move a car is from chemical energy to heat energy.
One of the fundamental laws in chemistry postulates that "energy is neither created nor destroyed but transformed from one form to another".
This law suggests that energy can be transformed from one form to another.
- In an automobile, the fuel is chemical compound with chains of hydrocarbons.
- When these bonds are broken during combustion in the engine, the chemical energy, a form of potential energy, is converted to heat energy, a form of kinetic energy.
- The heat energy is used to drive pistons and cause the mechanics of a car to begin to move.
Answer:
shows how anything like each thing is composed of for instance see how water is made of: hydrogen and oxygen which makes it a compound
