The percentage purity of the sodium hydroxide will be 37.5%.

option A is correct.

<h3>What is mass percentage?</h3>

Mass percentage is the amount of solute present in per hundred gram of a solution is called Mass percentage of solution.

Mass percentage = mass of component / mass of solution × 100

mass of component = 1.20g

mass of solution = molar mass of NaOH + molar mass of HCl

                            = 40 + 36.5

                             = 76.5

substituting the value in the equation,

mass percentage = 1.20 / 76.5

                             = 37.5%

Therefore, percentage purity of the sodium hydroxide will be 37.5%.

option A is correct.

PLEASE EXPLAIN I KNOW THE ANSWER I NEED AN EXPLAINATION
BaLLatris [955]

From the graph shown, Y2 = N2, X2 = O2, Z2 = H2.

When atoms of elements are at a large distance from each other, the potential energy of the system is high. However, as the atoms approach each other, the potential energy of the system decreases steadily. The closer the atoms come to each other, the lower the potential energy. This implies that potential energy is proportional to bond length.

Since N2 has a shorter bond length and higher energy, Y2 must be N2. The bond energy of hydrogen is small hence H2 must be X2. The bond energy of a double bond is intermediate between that of a single and triple bond hence Z2 must be O2.

What is the standard emf of a galvanic cell made of a cd electrode in a 1.0 m cd(no3)2 solution and a cr electrode in a 1.0 m cr
Natali5045456 [20]
Standard reduction potential of Cd2+ = -0.403 v
Standard reduction potential of Cr3+ = -0.74 v

Here, reduction potential of Cd2+ is higher as compared to Cr3+. Hence, it will preferentially undergo reduction. 

The electrochemical cell is represented as
Cr/Cr3+// Cd2+/Cd

Now, standard EMF of cell = E = ECd2+/Cd - ECr3+/Cr  
                                                  = - 0.403. - (-0.74)
                                                  = 0.337 v

How many moles of KCL is in a 3M solution of KCL
inna [77]

Answer:The thing to remember about a solution's molarity is that you can express it as a fraction that has 1 L of solution as the denominator. In your case, a 2.0-M potassium chloride solution contains 2.0 moles
