Explanation:
Carbon black sphere
Nitrogen blue sphere
Chlorine green sphere
Hydrogen white sphere
Reactants:
three molecules that contain one black sphere and four white spheres
3CH₄
three molecules that contain two blue spheres and four green spheres:
3N₂Cl₄
Products:
three molecules that contain one black sphere and four green spheres:
3CCl₄
three molecules that contain two blue spheres:
3N₂
six molecules that contain two white spheres
6H₂
The reaction proper:
3CH₄ + 3N₂Cl₄ → 3CCl₄ + 3N₂ + 6H₂

Answer:
Eght: 0
Explanation:
The work formula is W = F*d where d is displacement (which means the direction matters)
Same amount of work.
Eight
Time does not matter in Work. Force and Distance do.
F = 50 N
s = 0 The only work you have done is move the ball above your head. Thereafter you just held it.
t = 15 but no work is done. Tell your tired muscles that as they try and deal with holding a 5 kg mass above you head.
W = 0
Nine
Again from the last question you should be able to tell that time does not matter. The force is the same for both of you (that's why he's your identical twin).
So the work is the same. You both weigh the same. You both went the same distance.

Answer:
Mass = 525.36 g
Explanation:
Given data:
Mass of CO₂ formed = ?
Mass of CH₄ burned = 191 g
Solution:
Chemical equation:
CH₄ + 2O₂ → CO₂ + 2H₂O
Number of moles of CH₄:
Number of moles = mass/molar mass
Number of moles = 191 g/ 16 g/mol
Number of moles = 11.94 mol
Now we will compare the moles of CH₄ and CO₂.
CH₄ : CO₂
1 : 1
11.94 : 11.94
Mass of CO₂:
Mass = number of moles × molar mass
Mass = 11.94 mol × 44 g/mol
Mass = 525.36 g
