Reactants: H₂SO₄ + 2 NaOH
Products: 2 H₂O + Na₂SO₄
The answer is A.
.500 mol ( 6.02x10^23 molecules/1 mol) = 3.01x10^23
Answer:
V
Explanation:
Firstly let’s list the names of the atoms
1. Sodium
2. Magnesium
3. Aluminum
4. Oxygen
5.Chlorine
Generally, anions have greater electron affinity than cations. Hence, they have more positive values for this electron affinity. This means that the higher the electron affinity, the greater its positive value
Electron affinity increases across a period. Thus, it is expected that chlorine has the highest value
1. In this reaction, 2 moles of nitrogen gas reacts with 3 moles of oxygen gas to give 2 moles of N2O3 gas. 2 nitrogen molecules react with 3 oxygen molecules to give 2 N2O3 molecules. Under STP, one mole of an ideal gas occupies a volume of 22.4 liters. So in this reaction, 44.8 liters of nitrogen gas reacts with 67.2 liters of oxygen gas to give 44.8 liters of N2O3 gas. The total mass of the reactants (N2 and O2) is the same as the total mass of the product (N2O3). This is called mass balance of a chemical reaction.
2. According to the chemical reaction, 3 moles of chlorine gas produces 2 moles of iron(III) chloride. So, to produce 1 moles of iron(III) chloride, 3/2 (1.5) moles of chlorine gas is required. Therefore, to produce 14 moles of iron(III) chloride, 14 x 1.5 = 21 moles of chlorine is needed.
