It will belong to the metals because metals bond with nonmetals like chlorine to form ionic compounds
Answer:
The concentration of H⁺ in stomach acid is approximately ten times greater than that of lemon juice.
Explanation:
The H⁺ concentration of a solution is exponentially related to its pH value:
![\rm [H^{+}] = 10^{-pH}](https://tex.z-dn.net/?f=%5Crm%20%5BH%5E%7B%2B%7D%5D%20%3D%2010%5E%7B-pH%7D)
.
For lemon juice:
![\rm [H^{+}] = 10^{-2.0} = 0.01\; M](https://tex.z-dn.net/?f=%5Crm%20%5BH%5E%7B%2B%7D%5D%20%3D%2010%5E%7B-2.0%7D%20%3D%200.01%5C%3B%20M)
.
For stomach acid:
![\rm [H^{+}] = 10^{-1.0} = 0.1\; M](https://tex.z-dn.net/?f=%5Crm%20%5BH%5E%7B%2B%7D%5D%20%3D%2010%5E%7B-1.0%7D%20%3D%200.1%5C%3B%20M)
.
Thus, the concentration of H⁺ in stomach acid is approximately ten times greater than that of lemon juice.
Answer:
A
Explanation:
The lithosphere represents the layer of hardened/solid rock that makes up the hard part of the earth, including the brittle upper portion of the mantle and the crust. The lithosphere is broken into pieces that are referred to as plates. The pieces move to and away from each other in a process known as plate tectonics. The movement of plates accounts for the global locations of volcanoes, earthquakes, and mountain ranges.
<em>The lithosphere is made of largely of inorganic materials known as silicates. The weathering of the solid rocks together with the interaction of living organisms gives rise to soil with an appreciable amount of organic materials.</em>
The correct option is, therefore A.
Answer:
≈170.22 [gr].
Explanation:
1) M(Cu₂CO₃)=2*64+12+3*16=188 [gr/mol];
2) the part of copper in Cu₂CO₃ is:
3) 16/47% of 500 [gr] is:
![500*\frac{16}{47}=170.22[gr].](https://tex.z-dn.net/?f=500%2A%5Cfrac%7B16%7D%7B47%7D%3D170.22%5Bgr%5D.)
