Answer:
KCl
Explanation:
Look at the electronegativity differences between the pairs of elements:
KCl: 3.16 - 0.82 = 2.34
BeCl: 3.16 - 1.57 = 1.59
LiCl: 3.16 - 0.98 = 2.18
ClO: 3.44 - 3.16 = 0.28
KCl has the highest electronegativity difference; thus it is the most ionic bond of the 4.
Answer:
B.the velocity for the forward reaction equal that of the reverse reaction
Explanation:
A state of rest or motion of a system is described as equilibrium.
For a system to be in equilibrium, the following conditions must be met:
1. It must be involved in reversible chemical process no matter how small the extent of the reversibility.
2. The rate of forward process is equal to the rate of backward or reverse process.
3. The system must be closed.
4. There is no change in the concentration of each of the species in equilibrium with respect to time. There must be a constancy of concentration of each species in the equilibrium process.
When we change any of the conditions of equilibrium, the Le Chatelier's principle comes into play.
The principle states that "if any of the conditions of a system in equilibrium is changed, the system will adjust itself in order to annul the effect of the change".
Answer:
ummm what is that give me more detail please
Physical changes are changes affecting the form of a chemical substance, but not its chemical composition. Physical changes are used to separate mixtures into their component compounds, but can not usually be used to separate compounds into chemical elements or simpler compounds.
