Sulfuric acid is an important chemical in industrial production of many products. In the “old” days, it was called oil of vitriol. It is commonly dyed brown now to alert people to its hazards because it is hugely corrosive. It is commonly found in car batteries. What is the molarity of 25.9 moles of sulfuric acid dissolved in 4.00 L of solution?

(Help would be greatly appreciated, chemistry is not my strong suit) How many moles of NaCl are present in a solution with a molarity of 8.59M and 125mL of a solution?
1. 1.07g
2. 62.7mol
3. 1.07mol
4. 62.7g

If more reactants are used in a chemical reaction, more products will be
produced. This is because *
1 point
More reactants have more atoms to react to form more products
More reactants take up the same volume
Too many products can slow down the reaction
More reactants cause the reaction to heat up

To investigate the effect of salt water on a cell, a researcher places one cell sample in freshwater and a second cell sample in salt water. After six hours, the researcher observes and sketches the two cells as shown. What change in the cells occurred during the six hours the cells remained undisturbed? A.Osmosis occurred in the salt water cell sample because the water from inside the cell moved out of the cell to a lower concentration, causing the cell to shrink. B.Osmosis occurred in the freshwater cell sample because the water from outside the cell moved into the cell to a higher concentration, causing the cell to grow. C.Osmosis occurred in the salt water cell sample because the salt from outside the cell moved into the cell to a lower concentration, causing the cell to shrink. D.Osmosis occurred in the freshwater cell sample because the salt from inside the cell moved out of the cell to a higher concentration, causing the cell to grow.
