Answer:
1.16 moles CO₂
Explanation:
To find the moles of CO₂, you need to (1) convert grams C₈H₁₈ to moles (via the molar mass) and then (2) convert moles C₈H₁₈ to moles CO₂ (via the mole-to-mole ratio from equation coefficients). It is important that the conversions/ratios are arranged in a way that allows for the cancellation of units. The final answer should have 3 significant figures like the given value.
Molar Mass (C₈H₁₈): 8(12.011 g/mol) + 18(1.008 g/mol)
Molar Mass (C₈H₁₈): 114.232 g/mol
2 C₈H₁₈ + 25 O₂ -----> 16 CO₂ + 18 H₂O
^ ^
16.6 g C₈H₁₈ 1 mole 16 moles CO₂
-------------------- x ----------------- x ------------------------- = 1.16 moles CO₂
114.232 g 2 moles C₈H₁₈
<span>a long high sea wave caused by an earthquake, submarine landslide, or other disturbance, is the definition. </span>
A possible answer is generalizations
I believe the correct answer from the choices listed above is option D. The molar mass of <span>Mg(ClO2)2 is obtained by adding the atomic masses of each atom in the compound and the result is 159.21 g per mole. Hope this answers the question. Have a nice day.</span><span />
The results of Rutherford's experiment were surprising as most of the alpha particles went straight without any deflection
<h3>Rutherford's Gold Foil experiment:</h3>
During the experiment, Rutherford directed beams of alpha particles at the thin gold foil and observed the following things:
- Most of the alpha particles passed straight without any deflection
- Few alpha particles got deflected from their paths on small angles
- Very few alpha particles got deflected from their paths on very large angles
<h3>Results of the experiment:</h3>
- Most of the space inside an atom is empty
- The center of the atom is occupied by a tiny positively charged dense body called a nucleus. Most of the mass of the atom is concentrated in the nucleus
- The electrons revolve around the nucleus in circular orbits and are called planetary electrons
Thus, the results of the experiment were surprising due to the above-stated facts.
