<span>Although the nucleus of an atom is very important, it is the electrons of the atom that determine its chemical properties.

Number of electrons of an atoms (the number of electrons in the outermost level mostly) determine the type of the element (whether it is a metal, metalloid or non-metal).
Based on this, the types of bonds that the atom can form (whether ionic or covalent) is determined, the type of reactions that the element can form is known and the elements that can react with it are also know.</span>

In the chemical formula 2so2, how many total atoms of sulfur (s) are there? 1 2 4
babunello [35]
Sulfur has the coefficient of 2, and nothing else. This indicates Sulfur has 2 atoms. 


<span>Oxygen on the other hand, has a subscript of 2, as well as the coefficient of 2. Multiplying those, and you see Oxygen has 4 atoms. 
</span>
So your answer is 2

Also remember there is a 2 in front of S meaning there are 2 Sulfurs. 
<span>If it was S02 it would be 1 Sulfur as there is no number in front of sulfer. </span>

<span>Remember the number in front of a element, represents how many atoms there are :)</span>

What is the percent composition of CuO if a sample of CuO with a mass of 62.5 g contains 12.5 g of oxygen (O) and 50 g of Cu
Arlecino [84]

Percent (%) Composition of CuO

Cu = 1 x 50g      - Multiply by one as there is one Cu

O = 1 x 12.5g      - Multiply by one as there is one O

CuO = 62.5g

% for Cu = 50g over 62.5 multiplied by 100 = 80%

% for O = 12.5g over 62.5 multiplied by 100 = 20%

Final Answer :

<em>Percent (%) Composition of CuO = </em>80% (Cu) & 20% (O)

The enthalpy change for converting 10.0 g of ice at -25.0 °C to water at 90.0 °C is __________ kJ. The specific heats of ice, wa
Nina [5.8K]
AH1 = m * c1 * AT1 calculate this for ice (-25C to 0C) AH2 = AHfus(1 mole)=6.01 kJ = 6010 J AH3 = m *c3 * AT3 calculat this for water (0C to 100C) AH4 = AHvap(1mole)=40.67 kJ = 40670 J AH5= m * c5 * AT5 calculate this for steam (100C to 125C) 
Sum ---- AH1+AH2+AH3+AH4+AH5 
Data m=18g (1mole water) 
c1=specific heat ice= 2.09 J/g K c3=specific heat water= 4.18 J/g K c5=specific heat steam= 1.84 J/g K 
AT = (Tend - Tinitial) as this is a difference between temperatures it doesn't matter the units Celsius or Kelvin. Kelvin (K)=Celsius (C)+273.15 
AT1 = 0C - (-25C)= 25C= 273.15K - 248.15K= 25K AT3= 100C - 0C = 100C= 100K AT5= 125C - 100C= 25C=25K
