The liquid part of a homogeneous mixture is most often than not the a. solvent
This depends on the type of homogeneous mixture at hand. For a liquid-solid homogeneous mixture, the liquid works as the solvent. For a gas-liquid homogeneous mixture, the liquid often works as the solvent as well. However, for a liquid-liquid homogeneous mixture, the liquid acts as both the solute and solvent.
The rate<span> of a </span>reaction increases<span> if the temperature is increased, the concentration of a dissolved reactant is increased and the pressure of a </span>reacting<span> gas is increased. Hope this answers the question. Have a nice day. Feel free to ask more questions.</span>
You can change any variable in an experiment (the amount of water, sun, type of light, fertilizer etc.) but for the experiment to be VALID only one thing can be changed for the experiment.
Example: I’m trying to see if the plant will grow better with more or less water so the only thing that changes is the amount of water. Everything else will have to be the same (type of plant, fertilizer,dirt, container it grows in, amount of light etc.)
