Answer:
Like Earth, it gets plenty of sunlight. We don’t see the far side because “the moon is tidally locked to the Earth,” said John Keller, deputy project scientist for NASA’s Lunar Reconnaissance Orbiter project. “The moon does rotate, but it rotates at the same speed that it rotates around the Earth.”
Explanation:
If you mean carbs, then you don't eat as much pasta and bread and stuff like that. So practically, all of the good stuff. Use techniques. Tell yourself that it will make you thinner if you don't eat it. I also tell myself that I am stronger than this and that food shouldn't control me. It might or might not work for you.
Hope I could help!
I believe it is C. Increase the temperature of coal
A sample of tennantite with mass of 2370 g contains 19.23 mol Cu.
You must make the following conversions:
Mass of tennantite → moles of tennantite → moles of Cu
<em>Step 1</em>. Calculate the <em>moles of tennantite</em> (Tn)
The <em>ideal </em>chemical formula of Tn is Cu_12As_4S_13.
Molar mass = (12×63.55 + 4×74.92 + 13×32.06) g/mol
= (762.60 + 299.68 + 416.78) g/mol = 1479.06 g/mol
Moles of Tn = 2370 g Tn × (1 mol Tn/1479.06 g Tn) = <em>1.60 24 mol Tn
</em>
<em>Step 2</em>. Calculate the <em>moles of Cu</em>
Moles of Cu = 1.6024 mol Tn × (12 mol Cu/1 mol Tn) = 19.23 mol Cu
