Does the iconic compound NaCl have the same particles as the individual elements of sodium and chlorine gas
valentina_108 [34]

Answer:It is not the same

Explanation: the normal sodium atom has an atomic number of 11 while Chlorine has an atomic number of 17. For Nacl; the sodium has lose an electron because it want to attain it octet configuration while chlorine accept the electron release to make it attain its octet configuration. At this point the elements are electrically stable.

Therefore, sodium become 10 and chlorine become 18

What are differences and similarities between water and atoms?Explain
REY [17]

Answer:

Atom may be defined as the smallest particle of an element which does not exist free in nature but takes part directly in chemical combinations. 

Atom of any element is represented by the symbol of that element. For example, hydrogen atom is represented by H, sodium atom is represented by Na, etc. 

Molecule may be defined as the smallest particle of an element or compound which exists free in nature but does not participate directly in chemical combinations. 

Molecule of any substance is represented by their molecular formula. For example, water molecule is represented by H2O. It tells that each water molecule contains two atoms of hydrogen and one atom of oxygen.

4. How many milligrams are in 5.25 x 10-13 kg?<br><br> the “-13” is an exponent
rusak2 [61]

5. 25 x 10⁻⁷mg

Explanation:

This is mass conversion from mg to kg;

The kg is a quantity of mass used to measure the amount of matter in a substance.

   Given mass = 5.25 x 10⁻¹³kg

The kilo-  is a prefix that denotes 10³

  therefore;

         1000g = 1kilogram

 the milli-  is a prefix that denotes 10⁻⁻³

       1000mg = 1g

Now that we know this, we can convert:

   5.25 x 10⁻¹³kg  x \frac{1000g}{1kg}  x \frac{1000mg}{1g}   =  5. 25 x 10⁻¹³ x 10⁶mg

      =  5. 25 x 10⁻⁷mg

#2: A gas at unknown pressure and a volume of 66 cm has its pressure changed to 150 kPa. The new volume
Murljashka [212]

Answer:

<h2>377 kPa</h2>

Explanation:

The original pressure can be found by using the formula for Boyle's law which is

P_1V_1 = P_2V_2

where

P1 is the initial pressure

P2 is the final pressure

V1 is the initial volume

V2 is the final volume

Since we're finding the original pressure

P_1 =  \frac{P_2V_2}{V_1}  \\

150 kPa = 150,000 Pa

We have

P_1 =  \frac{150000 \times 166}{66}  =  \frac{24900000}{66}  \\  = 377272.72...

We have the final answer as

<h3>377 kPa</h3>

Hope this helps you
