Answer:
Explanation:
Hello.
In this case, given the described reaction, the formation of nitric acid turns out:
Since two hydrogen atoms are present at the reactants we balance it as follows:
In such a way, since there is a 1:2 mole ratio between water and nitric acid, the produced moles of nitric acid, turns out:
Best regards!
Missing question: <span>A 5.00 L sample of O2 at a given temperature and pressure contains a 1.08x10^23 molecules. How many molecules would be contained in each of the following at the same temperature and pressure? </span>
a) 5.00 L H2.
<span>b) 5.00 L CO2.
Use </span>Avogadro's Law: The Volume Amount Law: <span>equal </span>volumes<span> of all gases, at the same temperature and pressure, have the same </span>number<span> of molecules. Because hydrogen and carbon(IV) oxide are gases, number of molecules are the same as number of oxygen molecules, so:
a) N(H</span>₂) = 1.08·10²³.
b) N(CO₂) = 1.08·10²³
Answer:
The highest biogenic silica accumulation rates in this area are observed in the South Atlantic, with values as large as 53 cm. kyr−1 during the last 18,000 yr. Further, extensive biogenic silica accumulation has been recorded in the deep-sea sediments of the Bering Sea, Sea of Okhotsk, and Subarctic North Pacific.
Explanation:
Answer: The key difference between dissociation and solvation is that dissociation is the breakdown of a substance into the atoms or ions from which the substance is made of whereas solvation is the dissolution of a substance in a solvent due to the attraction forces between the solvent molecules.
