What is the formula for the compound dinitrogen pentoxide? n4o5 n5o4 n4o6 n5o2 n2o5?
2 answers:
Answer:
Explanation:
Dinitrogen pentoxide is a covalent compound because sharing of electrons takes place between nitrogen and oxygen. Both the elements are non-metals and hence, will form covalent bond.
The nomenclature of covalent compound is given by:
1. The less electronegative element is written first.
2. The more electronegative element is written then, and a suffix is added with it. The suffix added is '-ide'.
3. If atoms of an element is greater than 1, then prefixes are added which are 'mono' for 1 atom, 'di' for 2 atoms, 'tri' for 3 atoms and so on.
Thus the chemical formula for dinitrogen pentoxide is

Answer : The final volume of gas is, 11.5 L
Explanation :
Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.
The combined gas equation is,
where,
= initial pressure of gas = 2.30 atm
= final pressure of gas = 5.40 atm
= initial volume of gas = 20.0 L
= final volume of gas = ?
= initial temperature of gas = 308 K
= final temperature of gas = 416 K
Now put all the given values in the above equation, we get:
Therefore, the final volume of gas is, 11.5 L
Answer: The pH will be 3.87
Explanation:
pH or pOH is the measure of acidity or alkalinity of a solution.
pH is calculated by taking negative logarithm of hydrogen ion concentration.
According to stoichiometry,
1 mole of gives 1 mole of
Thus moles of
gives =
moles of
Putting in the values:
Thus the pH will be 3.87
