Balanced equation:
Pb(SO₄)₂ + 2 Zn → 2 ZnSO₄ + Pb
From the equation we found that 2 moles of Zn form 2 moles of ZnSO₄
so 0.582 mole of Zn will produce 0.582 ZnSO₄
Molar mass of ZnSO₄ = 161.47 g/mole
Mass of ZnSO₄ formed = 161.47 x 0.582 = 94.0 grams
Answer:
the awnser is Cart A.
cart A has a mass of 14 kg but is pushed with 25newtons of force and 25 is 11 more than 14 and it just kind of makes sense.
and cart B has a mass of 12kg and is pulled with 19newtons and 19 is 7 more than 12.
Hope this helps!
Answer:
The volume of water added is 30 mL
Explanation:
Given data
- Initial concentration (C₁): 0.4 M
- Initial volume (V₁): 10 mL
- Final concentration (C₂): 0.1 M
We can find V₂ using the dilution rule.
C₁ × V₁ = C₂ × V₂
0.4 M × 10 mL = 0.1 M × V₂
V₂ = 40 mL
The volume of water added is
V₂ - V₁ = 40 mL - 10 mL = 30 mL
