Answer:
2 Moles
Explanation:
12 grams of carbon contains 1 mole
1 gram contains [1 mole/ 12 grams ] x 1 gram
24 grams contains [1 mole/ 12 grams ]* 24 gram = 2 moles.
For #1, I'd say it's "It will usually bond to multiple atoms which can provide a total of 4 additional electrons."
2. Ionic (I'm quite certain because anions/cations (-1 & +1) are Ionic from what I recall, if that's true it's Ionic.
3. "comparison of the associated families to which the elements belong" and
"the difference in electronegativities" are what I would choose, as I mentioned in a comment earlier.
If I'm wrong let me know, but I am at least 80% sure that these responses are correct from what I remember in Chemistry.
I believe the answer to your question is none of the above
Answer:
B. wave 1 has a larger wavelength than wave 2
It differs because a steam turbine runs off of a magnetic field and a steam engine runs off of coal
hope this helps :)
