Fill in the blank
The (blank) of a rock is a result of its mineral composition.
Answer:
Color
Answer:
Write the balanced reaction equation. From this, note the mole ratio of Na to H₂; this enables you to know the number of moles of H₂ produced.
This technique is in your lecture notes and/or your chemistry textbook, so you should not have to ask Quorans to do your homework. (Take the hint.)
Explanation:
Types of Bonds can be predicted by calculating the difference in electronegativity.
If, Electronegativity difference is,
Less than 0.4 then it is Non Polar Covalent
Between 0.4 and 1.7 then it is Polar Covalent
Greater than 1.7 then it is Ionic
For Li and O,
E.N of Oxygen = 3.44
E.N of Lithium = 0.98
________
E.N Difference 2.46 (Ionic Bond)
For Cl and F,
E.N of Fluorine = 3.98
E.N of Chlorine = 3.16
________
E.N Difference 0.82 (Mildly Polar Covalent Bond)
For Ca and S,
E.N of Sulfur = 2.58
E.N of Calcium = 1.00
________
E.N Difference 1.58 (Polar Covalent Bond)
