The balance equation for the reaction between sodium bicarbonate and hydrochloric acid:
The reactants and react in the ratio 1:1. So we use the mass of sodium bicarbonate and molar mass to find the number of moles produced.
.
.
Again we use the fact that the stochiometric ratio are 1:1:1:1:1, hence the moles of are 24.977moles.
So we used the ideal gas law , where P is the pressure, V is the volume, R the gas constant, is and T is the temperature in kelvins. We make V the subject
The answer is supposed to be in L, , so
An isotonic environment is when the concentration of solutes and solvent (water) are the same.
<span>When a cell is hypertonic, it shrinks because the concentration of solvent/solutes are unequal. If the inside of the cell has less solutes and more solvent, the solvent inside (water) will diffuse out the cell because of the concept of "going doing the concentration gradient". Anything will travel from a high concentration to a low concentration. In the case of hypertonic, water will move out the cell and causes it to shrink. </span>
<span>Hypotonic is when the cell is enlarged by water moving inside. So a hypotonic cell will look like it's big and expanded. Water goes where there is less concentration of it. You can also think about it from another perspective. Water always go where there is more solutes. So if the solute concentration like sodium or sugar or ect. is greater inside a cell or a piece of potato, then water will go there (since if there is a high concentration of solutes, then there is low concentration of solvent). </span>
I'm not so sure but I would say it could be an iconic bond!
Answer:
See explanation
Explanation:
We have to remember that the formula of <u>sulfur dioxide</u> is . So, the "S" atom is the central one and the "O" atoms are in the left and right of S. Additionally, "S" and "O" atom has <u>6 valence electrons each</u>. With this in mind, we can start with a structure in which the left oxygen has 2 lone pairs and a double bond, the S atom can have a double bond a single bond and a lone pair and the right oxygen with 3 lone pairs with a single bond <u>(structure A)</u>. Now, if we move the negative charge in the right (resonance) to the middle and the double bond to the left oxygen we will obtain <u>structure B</u>. Finally, we can move the negative charge in the left to the middle and we will obtain structure C. (See figure 1).
Answer:
Glucose is a primary source of energy for living organisms. Animals transport glucose and oxygen to tiny structures in their cells, called mitochondria.
Hope this helps ;-))
