Answer: 48800g
Explanation:
Using the mathematical relation : Moles = Mass / Molar Mass
Moles = 488
Molar mass of CaCO3 = 40 + 12 + (16 x 3) = 100g/mol
Therefore
488 = mass / 100 = 48800g

Answer:</h3>
6AgI + Fe₂(CO₃)3 → 2FeI₃+ 3Ag₂CO₃
<h3>
Explanation:</h3>
- The process of balancing chemical equations involves putting coefficients on reactants and products to ensure the number of atoms of each element is equal on both sides of the equation.
- It is a try and error method that is done to make an equation obey the law of conservation of mass.
In this case;
- Our unbalanced equation is, AgI + Fe₂(CO₃)3 → FeI₃+ Ag₂CO₃
- It can be balanced by putting the coefficients 6, 1, 2, 3.
- Therefore, the balanced chemical equation is;
6AgI + Fe₂(CO₃)3 → 2FeI₃+ 3Ag₂CO₃
Answer:
11.4 moles
Explanation:
Your chemical equation for the reaction of zinc and nitric acid will be
Zn + 4 HNO₃ --> Zn(NO₃)₂ + 2 NO₂ + 2 H₂O
To solve the problem, you need to use stoichiometry. For every 1 mole of zinc, you will need 4 moles of nitric acid. Divide 45.60 by 4. Your answer should be 11.4 moles.
