Answer:
Mg(s) + 2H⁺ → Mg²⁺(aq) + H₂.
Explanation:
- To obtain the overall reaction, we sum the two half-reactions and omit the similar species in the reactants and products sides.
oxidation reaction:
Mg(s) → Mg²⁺(aq) + 2e.
Reduction reaction:
2H⁺ + 2e → H₂.
- So, we add the two half-reactios and obtain the overall reaction:
<em>Mg(s) + 2H⁺ → Mg²⁺(aq) + H₂.</em>

If the volume exiting the large intestine were 364 mL, then it would most likely indicate a case of diarrhea. This condition may lead to dehydration.
<h3>Diarrhea: causes and diagnosis</h3>
Diarrhea is an unhealthy condition that occurs when the body excretes an excessive amount of water.
Diarrhea must be treated because this condition can lead to dehydration (it may even lead to death in severe cases).
Both diarrhea and vomiting may lead to the loss of body fluids.

<u>Answer:</u> The percent yield of the compound is 30.86 %.
<u>Explanation:</u>
To calculate the percentage yield of a compound, we use the equation:
Experimental yield of compound = 25 g
Theoretical yield of compound = 81 g
Putting values in above equation, we get:
Hence, the percent yield of the compound is 30.86 %.
Answer:
0.86 moles H₂O
Explanation:
To solve this problem, it is important to first determine the balanced chemical equation. The balanced equation is necessary as it will provide the mole-to-mole ratio needed to convert between moles O₂ and moles H₂O.
The unbalanced equation:
C₈H₁₈ (l) + O₂ (g) ---> CO₂ (g) + H₂O (g)
<u>Reactants:</u> 8 carbon, 18 hydrogen, 2 oxygen
<u>Products:</u> 1 carbon, 2 hydrogen, 3 oxygen
As you can see, the equation is not balanced because there are unequal amounts of each element on both sides. Balancing the equation is a matter of guessing-and-checking to see which combination of coefficients work.
The balanced equation:
2 C₈H₁₈ (l) + 25 O₂ (g) ---> 16 CO₂ (g) + 18 H₂O (g)
<u>Reactants:</u> 16 carbon, 36 hydrogen, 50 oxygen
<u>Products:</u> 16 carbon, 36 hydrogen, 50 oxygen
Now that the equation is balanced, we can use the coefficients of O₂ and H₂O to construct our mole-to-mole ratio and perform our conversion. The final answer should have 2 sig figs to match the given value (1.2 moles). The state of matter is most likely not necessary to include in your final answer.
1.2 moles O₂ 18 moles H₂O
--------------------- x ----------------------- = 0.86 moles H₂O
25 moles O₂
If I understand this right, the two elements are Nickel and Copper, elements 28 and 28, respectively. A nickel is worth 5 cents, and a penny, originally comprised of copper, is worth one - the total being six cents.
