It means 10% of reactants have been converted into products and 90% are still there as reactants.
There is no Ptc stat. Do you mean Pct or Pts? Pct - Percent of Completed Passes (aka Completion Percentage) Pts - Total Points
This is a very fast reaction.
In everyday life, the word "rate" often refers to the speed or frequency at which something occurs, such as a heart rate or interest rate. In chemistry, "reaction rate" specifically describes how quickly a chemical reaction takes place, typically measured by the change in concentration of reactants or products over time. Factors such as temperature, concentration, and catalysts can influence this rate, determining how fast a reaction proceeds.
It means that whatever money is collected (the proceeds) through a certain activity will be donated to a specific organization... they should say where.
It would flow toward the weaker solution. The intent of osmosis is to gain equilibrium, so the 15 percent solution would gain sugar content until, if you allowed the osmosis to go to completion, the two solutions had the same amount of sugar in them. "Going to completion" doesn't necessarily mean 20 percent concentration on both sides. If you were to make a gallon bag out of dialysis membrane, fill it with 15 percent solution and put a stirrer in it, then drop it into a 25,000-gallon reaction vessel full of 25 percent solution with a stirrer in it, you might wind up with 24.9999999999 percent sugar solution in both bags.
bringing to completion
A line or course that proceeds by sharp turns in alternating directions
The meaning of the word proceeds is getting money from an event or activity in essence it's yield. The word proceeds can also mean to move forward and advance.
bring to completion or reality; achieve or realize
That depends on what you mean? Do you mean the relationship or reaction between the characters or the general reaction from the readers?
The arrow shows that something has changed into something else ie NaOH + HCl --> NaCl + H2O In English this translates as, Sodium hydroxide and Hydrochloric acid react to form Salt and water
finalización, consumación, realización, complemento.
