Answer: you have to be sure to cite evidence
Answer:
0.0872 M
Explanation:
Use the equation M1V1 = M2V2
0.436(50.0) = (x)(250.0)
21.8 = 250x
0.0872 = x
The answer is b. electric current.
Electric current is the flow of charges, and the electrons are negative charded particles that constitute matter.
The flow of electrons happens through conductor materials (wires). As the question says the movement of the electrons (flow) is induced by an electric field.
Answer:
The temperature of the solute/solvent without any external effect would decrease.
Explanation:
As the bonding between the solute particles is really strong, therefore a large amount of energy is required to overcome these forces. So that the new bonding between the solute and solvent is created.
In order to achieve this, there will be a lot of energy required and that is through the heating process. So the solution will require energy so the solute will dissolve fully either by provision of external force i.e stirring or by heating.
Explanation:
Answer:
True
Explanation:
A law is a summary of observed (measurable) behavior, whereas a theory is an explanation of behavior. A law tells what happens; a theory (model) is our attempt to explain why it happens.
