I'm not sure what the question is but 3 is an example of a prime number. I hope this help
Answer:
3.08 g of Oxygen .
Explanation:
2Mg + O₂ = 2MgO
2 mole 1 mole
molecular weight of Mg = 24
2 mol of Mg = 48 g
48 g of Mg reacts with 32 g of oxygen
4.62 g of Mg will reacts with 3.08 g of Oxygen .
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

25 moles O₂
Answer:
An electrical phenomenon is caused by flow of free electrons from one atom to another. The characteristics of current electricity are opposite to those of static electricity. Wires are made up of conductors such as copper or aluminum.
