*Necessary Information for the calculations*
Molar mass of carbon - 12.011 g/mol
Molar mass of copper - 63.546 g/mol
Molar mass of molecular oxygen - 31.998 g/mol
Avogadro's number - 6.022 x 10^23 atoms/mol
1. Moles of carbon in 19.2 grams of carbon (C)
To determine the number of moles carbon for a given mass of the substance, the mass of the sample is simply divided by its molar mass. Thus,
19.2 g C x <span><span> <u> 1 mol C </u></span><u> </u></span> = 1.599 mol C
12.011 g C
<span>
</span>2. Atoms of copper in 11.4 moles of copper (Cu)
To determine the number of atoms of a substance for a given number of moles, the latter is simply multiplied by Avogadro's number which represents the number of particles, molecules, or atoms of a any substance in 1 mole. Thus,
11.4 mol Cu x <u> 6.022x10^23 atoms Cu </u> = 6.865x10^24 atoms Cu
1 mole Cu
3. Mass of 3.15 moles of molecular oxygen (O2)
To determine the mass of a given number of moles of a substance, the former is simply multiplied by the molar mass of the substance. Thus,
3.15 mol O2 x <u> 31.998 g O2 </u> = 100.794 g O2
1 mole O2
4. Moles of silver in 6.51x10^24 moles of silver (Ag)
To determine the number of moles of a substance for a given number of atoms, the latter is simply divided by Avogadro's number. Thus,
6.51x10^24 atoms Ag x <u> 1 mol Ag </u> = 10.810 mol Ag
6.022x10^23 atoms Cu
Nitrogen atom has a valence electrons of 5 electrons. A full octet or full valence electrons shell is composed of 8 electrons. Hence, an additional of 4 electrons are needed for it to become full. this is achieved by covalent bonding where electrons are shared or ionic bonding where electrons are transferred.
Answer:
see attached
Explanation:
Two methods are shown in attached notes... Method I is based upon Experimental Rate Trends; Method II is the 'Ratio Method'.
Answer :
The formula of given compound is 
.
The steps involved in the Lewis dot structure of given molecule are :
Step 1 : First we have to determine the total number of valence electron in a
1 Carbon = 4 electrons
3 Hydrogen = 3 electrons
Sulfur = 6 electrons
Nitrogen = 5 electrons
Total number of valence electrons = 18 electrons
Step 2 : Draw the skeleton of the .
Step 3 : Placing a bonding pair of electrons between the atoms to form the chemical bonds.
Step 4 : The rest of the electrons are used as a lone pair for central or terminal atoms to achieve an octet to finish the Lewis dot structure.
According to the question, the sulfur and nitrogen atoms are bonded to the carbon atom in which the sulfur atom is bonded with carbon by double bond and nitrogen is bonded with carbon by single bond.
