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:
A. Is independent of other energy influences
Explanation:
Nuclear decay occurs at a constant rate. The rate of decay is independent of temperature.
B, C, and D are wrong. The decay rate cannot be sped up or slowed down at ordinary temperatures.
From Earth's<span> density we can estimate what elements must compose the </span>Earth; an iron core<span> just happens to estimate </span>Earth's<span> mass the best. Now from energy waves, geologists use seismometers to measure movements in </span>Earth's<span> interior (e.g. Earthquakes), These energy-waves form compressional and shear waves</span>
Answer:
A protein is more stable in its native form, because apart of weak interactions between R groups, it also presents other stronger interactions, as those including covalent bonds
Explanation:
For example, covalent bonds between sulfur atoms when disulfide bridges are built. These links are very difficult to break and maintains the protein shape. Disulfide bonds are a few but they use to incide in the structure of native proteins
