Answer:
Option B is correct More hydrogen carbonate is formed
Explanation:
Step 1: Data given
The Principle of Le Chatelier says 'If the concentration of one of the reaction partners changes, the balance will shift to counteract that concentration change.
Step 2: When adding more H2O
For the equation CO2 + H2O --> H2CO3
If the H2O concentration is increased, the system will attempt to undo that change in concentration by shifting the balance to the right, and so the H2CO3 concentration will increase.
Option B is correct More hydrogen carbonate is formed
Answer:
The correct answer is A: Hypertonic solution
Explanation:
Syrup is a solution with a <u>high concentration of sugar</u>. When you put the fruit in this solution, the syrup concentration is higher than the sugar concentration inside the fruit, this is called an <u>hypertonic solution</u>. Consequently, there is a gradient of concentration between the interior of fruit cells and the exterior. The water will go out from the cells towards the exterior, in favor of the concentration gradient. In this way, you are removing water from inside the fruit (drying).
To convert grams to moles, we need the molar mass of the element or compound. remember you can determine the molar mass of a molecule by adding the atomic mass of each atom from the periodic table.
molar mass of Na= 23.0 g/ mol
130 g (1 mol Na/ 23.0 grams)= 5.65 moles or 6 moles.
