Answer:
B. Add more water to decrease the concentration.
Explanation:
If we add more water to the solution, the concentration is decreased and like wise the conductivity of the solution.
- Concentration is the amount of solute in a solution.
- Conductivity deals with the ability of a solution to allow the passage of current.
Concentration and conductivity are directly proportional to one another. The higher the concentration, the higher the conductivity and vice versa.
- Adding more water increases the amount of solvent and the concentration reduces.
Answer:
139.11 grams
Explanation:
The molarity (M) is equal to m (moles) /L (liters).
Notice how it is in mL so converting it would be 0.75 L (750*10-3)
Now plug in the information
1.75=m/0.75
m=1.3125
Now m is in moles so convert to grams to get the mass
1.3125 mol Na2CO3 * 105.9888 g Na2CO3 = 139.1103
Answer:
No Reaction => Does not react to form a Driving Force compound
Explanation:
Answer:B is an ionic compound
Explanation:This is because when we look at the properties of ionic compounds, we see that the form crystals just like salt(sodium chloride), they dissolve in water, have a high boiling and melting point, are hard due to the strong intermolecular forces between atoms and conduct electricity (only molten or in solution form)
