B because the climate has to be pretty balanced and if it’s too cold it won’t be habitable and if the climate is too hot it won’t be habitable aswell
Answer:
percipitate or sedements from chemical reactions
The air surrounding the hot plate would heat up through the process of convection
I think the correct answer from the choices listed above is option 2. When the products of a reaction are hotter than the reactants the reaction is endothermic. The change in temperature is a measure of energy difference of the states. Since energy must be conserved, so there must be a source of energy for the system.
Answer: The %v/v of the given KCl solution is 7.6%.
Explanation:
Given: Volume of solute =
Volume of solution =
Formula used to calculate %v/v is as follows.
Substitute the values into above formula as follows.
Thus. we can conclude that the %v/v of the given KCl solution is 7.6%.
