Answer is: 3,2 · 10¹¹ t of quicklime.Â
Chemical reaction: COâ‚‚ + CaO → CaCOâ‚.
m(CO₂) = 2184,82·10¹² · 115 = 2,51 · 10¹ⷠg.
n(COâ‚‚) = m(COâ‚‚)Â Ă· M(COâ‚‚)
n(CO₂) = 2,51 · 10¹ⷠg ÷ 44 g/mol = 5,7 · 10¹ⵠmol.
from reaction n(COâ‚‚) : n(CaO) = 1 : 1.
n(CaO) = 5,7· 10¹ⵠmol.
m(CaO) = 5,7· 10¹ⵠmol · 56 g/mol = 3,2 · 10¹ⷠg = 3,2 ·
10¹¹ t.
n - amount of substance
Answer:
We will need two potassium ions to balance the charge on the sulfate ion, so the proper chemical formula is K 2SO 4.
Explanation:
hope this helps
Answer:
Endocrine disruptor
Explanation:
This means that the four substances, even they are used in different areas like gardening, plastics or pots, all of them change the endocrine system in humans because they imitate the natural hormones and the body stops to produce them or starts to produce more hormones than the body needs.
They are correlate with some illness like cancer, thyroid problems and infertility.
<span>She must use Avogadro's Number. Avogadro's number is the number of molecules in a mole of a substance, so if you have 12.4 moles of something, then you have 12.4 times Avogadro's number of molecules.</span>
Electron - In an atom, the central part which is composed of neutrons and protons including quarks is called the nucleus. Whereas the electron is the particle with negative elementary electric charge can be found inside the atom surrounding the nucleus.
