Answer:
to study sub terranian earth movements
Explanation:
8H earth science
This means that the air in that city has less than a third of water vapor it could contain under the same circumstances. Relative humidity is the ratio of water vapor that the air contains to the maximum amount it could carry at the same temperature. When the humidity is high the water vapor in the air is a lot and vice versa.
Answer:
See explanation.
Explanation:
Hello,
In this case, for the described chemical reaction:
2 HCl(aq) + Mg(OH)2(aq) → MgCl2(aq) + 2 H2O(l)
We can notice there is a 2:1 molar ratio between the moles of hydrochloric acid and magnesium hydroxide, therefore, at the equivalence point:
And in terms of volumes and concentrations we verify:
So we use the given data to proof it:
Therefore, we can conclude the data is wrong by means of the 2:1 mole ratio that for sure was not taken into account. This is also supported by the fact that normalities are actually the same, but the nomality of magnesium hydroxide is the half of the hydrochloric acid normality since the acid is monoprotic and the base has two hydroxyl ions.
Best regards.
Answer:
- carbon (C)
- hydrogen (H)
- oxygen (O)
- nitrogen (N)
- sulfur (S)
Explanation:
Amino acids are organic molecules which base chemical structure is composed by:
- a carbon atom (C)
- a carboxyl group (-COOH)
- an amino group (-NH₂)
- a side chain- called R group- which varies in different amino acids. It can be composed by N, H, O, C and sometimes S.
According to this, the five chemical elements that are present in amino acids are:
- carbon (C)
- hydrogen (H)
- oxygen (O)
- nitrogen (N)
- sulfur (S)
According to the law of conservation of matter, the number of Atoms<span> is not changed by a chemical reaction.
