Metathesis is a type of reaction in which the cations and anions exchange partners. this reaction is also called double replacement. Metathesis reactions are driven by the formation of a product .this reaction is classified into three different categories: formation of precipitate, f<span>ormation of a Weak or Non-electrolyte and production of the gas.</span>
Moles of NO formed : 0.833
<h3>Further explanation</h3>
Given
2.5 moles of NO2
Required
moles of NO formed
Solution
Reaction
3 NO₂(g) + H₂O(l) = 2 HNO₃(aq) + NO(g)
The reaction coefficient in a chemical equation shows the mole ratio of the compounds in the reactants and products
From the equation, mol ratio of NO₂ and NO = 3 : 1, so moles of NO :
Answer:
See explanation
Explanation:
The oxides or hydrides are formed by exchange of valency between the two atoms involved. The group of the atom bonded to oxygen or hydrogen in the binary compound can be deduced by considering the subscript attached to the oxygen or hydrogen atom.
Now let us take the journey;
R2O3- refers to an oxide of a group 13 element, eg Al2O3
R2O - refers to an oxide of group a group 1 element e.gNa2O
RO2 - refers to an oxide of a group 14, 15 or 16 element such as CO2, NO2 or SO2
RH2 - refers to the hydride of a group 12 element Eg CaH2
R2O7 - refers to an oxide of a group 17 element E.g Cl2O7
RH3- refers to a hydride of a group 13 element E.g AlH3
Answer:
58.6 g.
Explanation:
Hello there!
In this case, since the molecular formula of lithium thiocyanate is LiCNS and therefore its molar mass is 65.1 g/mol, it possible to perform the calculation of the mass of 0.900 moles of this substance by recalling the following equivalence statement:
1 mol = 65.1 g.
Thereby, we can calculate the required mass as shown below:
