Answer:
Ocean, lakes and rivers. Are all liquids.
Explanation:
Ocean, lakes and rivers. Are all liquids. Snow starts off as a liquid, evaporates into a gas and camoes back as snow.
Answer:
34.8 mL
Explanation:
First we <u>convert 5.48 g of CuNO₃ into moles</u>, using its<em> molar mass</em>:
- 5.48 g CuNO₃ ÷ 187.56 g/mol = 0.0292 mol
Now we can <u>calculate the volume of the solution</u>, using the <em>definition of molarity</em>:
- Molarity = moles / liters
- 0.840 M = 0.0292 mol / liters
Finally we <u>convert L into mL</u>:
- 0.0348 L * 1000 = 34.8 mL
Where are options? without that, i can’t help you sorry
Answer:
The answer to your question is No
Explanation:
Ionic bonding is a kind of bonding that involves the attraction between oppositely charged ions. That means that one element must have a positive charge and the other a negative charge.
Also, the difference in electronegativity of both elements must be higher than 1.7.
Both Sodium and Aluminum are positively charged then an ionic bond is not possible to be formed.
Difference of electronegativity = 1.61 (Al) - 0.93(Na)
= 0.63
To form an ionic bond the difference of electronegativity must be higher than 1.7.
