One mole of NaCl yields one mole of HCl, hence we'll make at most
That would be answer B (the difference probably comes from the molar mass of Cl that I chose, 35.5, whereas some prefer to take 35.4)
Final answer:
The question tackles stoichiometry, a Chemistry concept used to calculate reactant or product amount. Given 2 moles of H2SO4 and 2.56 moles of NaCl, the H2SO4 is limited, resulting in 4 moles of HCl. The weight of 4 moles of HCl is 146 g, thus, the answer is c. 146 g.
Explanation:
The subject of this question is stoichiometry, a method used in Chemistry to calculate the amount of reactants or products in a particular chemical reaction. According to the balanced equation, 2 moles of NaCl react with 1 mole H2SO4 to yield 2 moles of HCl. Meaning, 1 mole of H2SO4 can only react effectively with 2 moles NaCl. However, we have 2.56 mol of NaCl. This means that the H2SO4 is the limiting reagent. Thus, 2 mol H2SO4 will yield 4 mol of HCl (since it's 2:2 ratio).
The molecular weight of HCl is 36.5 g/mol. Therefore, the weight of 4 moles of HCl is 4 mol * 36.5 g/mol = 146 g. Thus, the correct answer is c. 146 g.

Answer : Option B) Accepts an H+ ion in reaction
Explanation : Acid is a lewis acid which forms a bond by accepting a pair of electrons. Acids, when dissolved increase the concentration of hydronium ion in the solution. So, the statement which is Acid accepts H+ ion is irrelevant here, as base accepts the H+ ion in a reaction.
Answer : The incorrect option is, Accepts an H⁺ ion in reaction.
Explanation :
Acid : It is a type of species which contains hydrogen ion.
Properties of an acid :
The taste of an acid is sour.
An acid does not feel slippery.
Acid reacts with the active metal to form a gas and a salt.
It change the color of litmus paper to red or pink.
It conduct electricity.
It react with carbonates to give salt.
It react with a metal to give compound and hydrogen gas.
Base : It is a type of species which contains hydroxide ion.
Properties of an base :
The taste of base is bitter.
The base feels slippery.
It does not react with the active metal.
It change the color of litmus paper to blue.
It conduct electricity.
As per question, all options are the properties of an acid while the statement accepts an H⁺ ion in reaction is in the property of an acid because it donates hydrogen ion in the solution.
Hence, the incorrect option is, Accepts an H⁺ ion in reaction.

The balanced chemical reaction is:
N2 + 3H2 = 2NH3
We are given the amount of H2 being reacted. This will be our starting point.
26.3 g H2 (1 mol H2 / 2.02 g H2) 2 mol O2/3 mol H2) ( 17.04 g NH3 / 1mol NH3) = 147.90 g O2
Percent yield = actual yield / theoretical yield x 100
Percent yield = 79.0 g / 147.90 g x 100
Percent yield = 53.4%
Answer:
53.4 percent yield, the fourth option
