I believe it remains the same? Not so sure though
Answer:
c. fluorine
Explanation:
A single replacement reaction is defined as the chemical reaction in which a strong molecule replaces the weak molecule from a compound.
In a single replacement reaction, the chloride ion in NaCl can be replaced by fluorine and gives Sodium fluoride as fluorine (F) is stronger than chlorine (Cl) and from other given molecules also. So the single replacement reaction between NaCl and F will be:
NaCl + F2 => NaF + Cl2
Hence, the correct answer is "c. fluorine".
Answer:
Molarity = 0.79 M
Explanation:
Given data:
Mass of KNO₂ = 67 g
Volume of solution = 1 L
Molarity of solution = ?
Solution:
First of all we will calculate the number of moles.
<em>Number of moles = mass/ molar mass</em>
Number of moles = 67 g / 85.10379 g/mol
Number of moles = 0.79 mol
Molarity:
Molarity = number of moles / volume in L
Molarity = 0.79 mol/1 L
Molarity = 0.79 M
