What is the mass concentration in ppm of NaCl of 0.01% mass/mass
Andreas93 [3]

Answer:

B-100

Explanation:

ppm is an unit of concentration that could be defined as the mass in mg of solute (In this case, NaCl) per kg of solution.

Now, a solution of NaCl that is 0.01% by mass, contains 0.01g of NaCl in 100g of solution.

To solve this question, we must convert the mass of NaCl to mg and the mass of solution to kg:

<em>Mass NaCl:</em>

0.01g * (1000mg / 1g) = 10mg

<em>Mass Solution:</em>

100g * (1kg / 1000g) = 0.10kg

The ppm are:

10mg / 0.10kg =

100ppm

Right answer is:

<h3>B-100 </h3>

What is reacitivty series, and how you can access reactivity of metals...
lubasha [3.4K]

In Chemistry, a reactivity series of metals , also known as the activity series refers to the arrangement of metals in the descending order based upon their reactivity .

<u>Salient Features</u> :-

  • The metal at the top of the reactivity series are powerful reducing agents since they are easily oxidized.
  • The reducing ability of metals grows weaker while traversing down the series.
  • The electro-positivity of metals also reduces while moving down the reactivity series.
  • Metals that are placed higher on the reactivity series have the ability to displace metals that are placed lower in the series.

<u>The metal reactivity series is given below</u> :-

To access the reactivity of metal , from the given reactivity series identify any of the metal and locate the reactivity based upon the choice of reactivity. The metal at the top (Potassium) is most reactive and the metal at the bottom (Platinum) is the least reactive.
