Answer:
The empirical formula is P2O5 (option B)
Explanation:
An empirical formula does not necessarily represent the actual numbers of atoms present in a molecule of a compound; it represents only the ratio between those numbers.
The actual numbers of atoms of each element that occur in the smallest freely existing unit or molecule of the compound is expressed by the molecular formula of the compound.
The molecular formula of a compound may be the empirical formula, or it may be a multiple of the empirical formula.
If the molecular formula is P4O10, this means for each for P-atoms we have 10-O atoms this is a ratio 4:10 or 1: 2.5
To find the empirical formula we divide the molecular formula by 2 what will give us P2O5
For each 2 P atoms we have 5 O-atoms. This is a ratio 1: 2.5
This is the simpliest form for the compound P4O10.
The empirical formula is P2O5 (option B)
Answer:
The volume of the sample is 17.4L
Explanation:
The reaction that occurs requires the same amount of CO and NO. As the moles added of both reactants are the same you don't have any limiting reactant. The only thing we need is the reaction where 4 moles of gases (2mol CO + 2mol NO) produce 3 moles of gases (2mol CO2 + 1mol N2). The moles produced are:
0.1800mol + 0.1800mol reactants =
0.3600mol reactant * (3mol products / 4mol reactants) = 0.2700 moles products.
Using Avogadro's law (States the moles of a gas are directly proportional to its pressure under constant temperature and pressure) we can find the volume of the products:
V1n2 = V2n1
<em>Where V is volume and n moles of 1, initial state and 2, final state of the gas</em>
Replacing:
V1 = 23.2L
n2 = 0.2700 moles
V2 = ??
n1 = 0.3600 moles
23.2L*0.2700mol = V2*0.3600moles
17.4L = V2
<h3>The volume of the sample is 17.4L</h3>
Answer: The net ionic equation when formic acid and sodium benzoate are mixed is as follows.
Explanation:
A chemical equation in which both reactants and products are present in the form of ions is called an ionic equation.
The chemical formula of formic acid is HCOOH and chemical formula of sodium benzoate is .
Therefore, net ionic equation when formic acid and sodium benzoate are mixed is as follows.
Answer:
2e⁻ are transferred in the formation of one formula unit of product
Explanation:
The reaction is:
2Rb + Br₂ → 2RbBr
In ground state, both elements have 0 as oxidation state.
In the RbBr, Rb acts with+1 and Br with -1.
Rb increased the oxidation state → Oxidation
Br decreased the oxidation state → Reduction
Rb → Rb⁺ + 1e⁻
Br₂ + 2e⁻ → 2Br⁻
Bromine had to gained 2 electrons, to decreased the oxidation state, so
(Rb → Rb⁺ + 1e⁻ ) ₓ2 = 2Rb → 2Rb⁺ + 2e⁻
(Br₂ + 2e⁻ → 2Br⁻) ₓ1 = Br₂ + 2e⁻ → 2Br⁻
2Rb + Br₂ + 2e⁻ → 2Br⁻ + 2Rb⁺ + 2e⁻
If we cancel the electrons, we reach the balanced reaction. In conclussion, 2 e⁻
