Answer:
Ionic or electrovalent bonds
Explanation:
The bond type that will result when the two atoms combine is an electrovalent or ionic bond. This is due to the large electronegativity difference between the given species.
- An ionic bond usually forms between metals and non-metals.
- The metal being electropositive has a very low electronegativity value.
- Non-metals are electronegative.
- The Cs will lose it electrons to F
- This leaves a net negative charge on F and a net positive charge on Cs.
Answer:
I believe this is a K-12 test question. If the answers below are what you have on your test . . .
- Precise
- Accurate
- Identical
- None of the above
Then the answer is <u>precise</u>.
A is correct because the fruit salad can be easily separated and the puch cannot so it is a solution and the fruit salad is a mixture.
Answer:
Explanation:
(a)The first liquid phase temperature required at 183°C
(b)By drawing a tie line and intersection with the liquidus line, the composition of the first liquid deduced is
61.8wt% of sand
38.2wt% of Pb
(c)By studying the diagram, phase diagram is on liquidus line, then
The complete melting point temperature of alloy is 260°C
(d)If a tie line is drawn it is deduced that thecomposition of the last solid remaining prior to complete melting is 13wt% of Sn
C)crabon,oxygen and calcium
