To form the value of 1500 in
scientific notation, it is
<span><span>
1.   
</span>By simply
moving the period which separates the whole numbers from the decimal numbers
between 1 and 5. </span>
<span><span>
2.   
</span>Thus, it
then becomes 1.5 </span>
<span><span>
3.   
</span>Next, is
you have to count how many moves the period made from its point of origin
hence, for this value is 3</span>
<span><span>4.   
</span>Therefore,
the scientific notation for the number is 1.5 x 10^3</span>
        
             
        
        
        
What types of atoms typically form covalent bonds? 
The correct answer: 
d) Nonmetals with nonmetals, because their difference in electronegativity is below 1.7.
En example to explain:
An example of a covalent bonding: HCl -> 2 nonmentals
-> a difference in electronegativity less than 1.7:
EN(Cl) = 3.0 and EN (H) = 2.1 (you can search these values in a periodic table)
/\EN = 3.0 - 2.1 = 0.9
0.9 < 1.7
I hope this helped you out!

Answer:
 K₂CrO₅
Explanation:
The empirical formula is the simplest formula of a compound. To find the empirical formula, we follow the procedure below: 
Elements                         Potassium                 Chromium         Oxygen
Mass                                  6.52                             4.34                  5.34 
Molar mass                          39                               60                      16 
Number of moles             6.52/39                     4.34/60             5.34/16 
                                              0.167                          0.072              0.333
Divide through by 
the smallest                      0.167/0.072             0.072/0.072          0.333/0.072
                                             2.3                               1                                4.6
                                              2                                 1                                  5 
Empirical formula K₂CrO₅
