What is the balanced equation for na2sio3 plus hf producing h2sif6 plus naf plus h2o?
It's been awhile since I did one of these, but I think it's: Na2SiO3 + 8HF produces H2SiF6 + 2NaF + 3H2O
What is a differences in concentration called?
concentration gradient
What is the difference between the concentration of a particular molecule in one area and the concentration in an adjacent area?
Concentration Gradient
Do substances in diffussion move with the concentration gradient?
no. High concentration to low concentration. The molecules move down the concentration gradient.
What kind of concentration does passive transport go to?
From high concentration to low concentration.
What is the name of formula H2SiF6?
Flourosilicic acid

What process occurs as water moves from a higher concentration to a lower concentration through a semipermeable membrane?
The answer for the crossword is "osmosis", although few people can understand the actual concept.
What is the difference between relative concentration and precise concentration?
Relative concentration gives you a comparison of two or more solutions, telling you which has a higher concentration of some solute than the other. Precise concentration would normally be expressed in terms of moles per liter, and it tells you the actual amount of a solute that is present in a given volume of solution.
What is van't hoff's factor?
Van't Hoff factor expresses how many ions and particles are formed, on average, in a solution from one formula unit of solute. It is the ratio between the actual concentration of particles produced when a substance is dissolved, and the concentration of a substance as is calculated from its mass.
How did the victims get to the concentration camp?
By getting in a boxcar. They would be transported by boxcars (look up: BOXCAR on google) and see the actual boxcars they were transported in.
What is the pH for sodium bicarbonate?
Sodium bicarbonate, NaHCO3 is alkaline so the pH will be greater than 7. However, the actual pH will depend on the concentration of the NaHCO3 solution.
Who built the concentration camps during the holocaust?
Except for the very earliest camps, the Nazi concentration camps were built on the orders of the SS. The actual building work was done by the first batch of prisoners, though in some cases existing, disused buildings were also used.
What is the difference in the concentration of a substance across a space is called concentration?
Concentration Gradient
Did the Jews have to run to the concentration camps?
A small number of Jewish prisoners were made Kapos, but they were never given any posts of real responsibility. The actual running of the camps were in the hands of the SS.
What is isotonic concentration?
Isotonic concentration is when the concentration of soletutes inside and outside of the cell are equal in concentration
What does it mean when you are going with the concentration gradient?
Going with the concentration gradient is basically the process of diffusion. Molecules going from a low concentration to a high concentration would be going with the concentration gradient. Going against the concentration gradient would be the movement of particles from a high concentration to a low concentration
