Answer:

37.5 g NaCl

Explanation:

Step 1: Given data

  • Concentration of NaCl: 15.0% m/m
  • Mass of the solution: 250.0 g

Step 2: Calculate how many grams of NaCl are in 250.0 g of solution

The concentration of NaCl is 15.0% by mass, that is, there are 15.0 g of NaCl every 100 g of solution.

250.0 g Solution × 15.0 g NaCl/100 g Solution = 37.5 g NaCl

Which layer of Earth has partially melted material that moves the tectonic plates?
beks73 [17]

The layer of Earth that has partially melted material that moves the tectonic plates is Mantle.  The correct option is C.

<h3>What are the layers of the Earth?</h3>

The Earth is divided into three layers: the crust, the mantle, and the core. This is the earth's outer layer, and it is composed primarily of solid rock, primarily basalt and granite. Oceanic crust and continental crust are the two types of crust.

The layer of Earth that has partially melted material that moves the tectonic plates is Mantle.

Thus, the correct option is C.

You believe you have cracked a secret code that uses elemental symbols to spell words. The code uses numbers to designate the el
Stells [14]

Explanation:

Atomic numbers for neutral atoms are the same as the number of electrons. The number of electrons are used in writing the subshell notation where we can see the highest princpal quantum number(n).

In order to solve this problem, a good knowledge of the periodic table and shell notation is required.  

For example;  

  Given a number 5;  

     We know the number is made of both the atomic number of the element and the highest quantum number.  

  It is easier for us to know the highest quantum number from the shell notation:  

        shell notation 1s²2s²2p¹

        highest principal quantum number is 2

  We are left with atomic number 5-2, which is 3

           The element is therefore Li.  

Part A.   5,     30,      58,      56,     99,     79,    19,     98,     9

             Li       Fe        I         Sb       U       Ta      S      Pa     N

Part B.   9,    99,    30,     95,     19,     47,     79

             N      U       Fe      Ra      S       Mo     Ta
