Answer:
Nitrogenous oxide/ nitrogen oxide
Explanation:
N2O is nitrogen oxide
The chemical purpose of heating the MnSO4⋅H2O is to eliminate water with the formation of new compounds.
<h3>Dehydration reactions</h3>
Dehydration reaction is a type of chemical reaction that involves the removal of water which would eventually lead to the formation of a new compound.
The molecule of MnSO4⋅H2O contains a molecule of water(H2O). After heating of the molecule, water is lost giving rise to the dry compound MnSO4.
Other examples of dehydration reactions are:
- Reactions that produce acid anhydrides.
- Reactions that involve the production of polymers.
- Reaction of sucrose with concentrated sulfuric acid
Therefore, the chemical purpose of heating the MnSO4⋅H2O is to eliminate water with the formation of new compounds.

Answer:
mg3n2 and cacl3 hope it helps
Answer:
b. First determine the mass of the sample and then convert it to the number of atoms using Avogadro's number and the molar mass of the element.
Explanation:
a. First determine the mass of the sample and then convert it to the number of atoms using the molar mass of the element. <em>FALSE. </em>As the mass is in grams and molar mass is in g/mol. This result in the moles of each element, not its number of atoms.
b. First determine the mass of the sample and then convert it to the number of atoms using Avogadro's number and the molar mass of the element. <em>TRUE. </em>Mass and molar mass will result in moles of element. These moles could be converted in number of atoms using Avogadro's number that is in # atoms per mole.
c.Use atomic microscope to determine Avogadro's number, then determine the mass of the sample and convert it to the number of atoms. <em>FALSE. </em>An atomic microscope is not used to determine Avogadro's number.
d.Use atomic microscope to count each atom. <em>FALSE. </em>There is not possible to count every single atom in an element. There are more atoms in a drop of water than stars in the sky.
