Substances that are not chemically bonded are mixtures.
Answer:
stretching and thinning of the Earth's crust occurs.
Explanation:
The result of the extension stress on Earth layers is the stretching and thinning of the Earth's crust occurs.
When there is a stress on the Earth's layers, the Earth's crust experiences the phenomena of stretching and thinning.
Assuming that you mean 10^-4 M then this would be basic and would have a pH of 10.
pOH = -log[OH].
So pOH = 4
pH=14-pOH
pH = 10
Energy can be conserved by efficient energy use.
Answer: Option A
<u>Explanation:</u>
Energy can be transferred from one form to another, but it cannot be destroyed or created. So it can be conserved if efficiently used. Thus efficient usage of energy lead to conservation of energy. Due to conservation of energy, the forces can be renewable and non-renewable.
So, we should know how the input energy can be completely converted to another form of energy leading to efficient usage of energy without any loss. As if there is no loss, input energy will be equal to output energy leading to 100% efficiency.
