Answer:
The answer to your question is the letter A. 1
Explanation:
Data
Chemical reaction
(NH₄)₂CO₃ ⇒ NH₃ + CO₂ + H₂O
Reactants Elements Products
2 Nitrogen 1
1 Carbon 1
8 Hydrogen 5
3 Oxygen 3
This reaction is unbalanced
(NH₄)₂CO₃ ⇒ 2NH₃ + CO₂ + H₂O
Reactants Elements Products
2 Nitrogen 2
1 Carbon 1
8 Hydrogen 8
3 Oxygen 3
Now, the reaction is balanced,
The coefficient for Carbon dioxide is 1
Answer:
2.41 M
Explanation:
The molarity is the moles of FeCl3 over the liters of solution. Since you're given mL you need to change it to L which is 0.12 L. 0.289 divided by 0.12 is your answer
Answer:
[H₃O⁺] = 6.31 x 10⁻³ M.
Explanation:
- To find the hydronium ion concentration [H₃O⁺], we can use the relation:
<em>pH = - log[H₃O⁺].</em>
<em></em>
∴ 2.2 = - log[H₃O⁺].
∴ log[H₃O⁺] = - 2.2
<em>∴ [H₃O⁺] = 6.31 x 10⁻³ M.</em>
