Answer:
40.1 g
Explanation:
The <em>balanced equation</em> is:
First we <u>convert 86.5 g of calcium chlorate into moles</u>, using its<em> molar mass</em>:
- 86.5 g Ca(ClO₃)₂ ÷ 206.98 g/mol = 0.418 mol Ca(ClO₃)₂
Then we <u>convert Ca(ClO₃)₂ moles into O₂ moles</u>, using <em>the stoichiometric coefficients of the balanced reaction</em>:
- 0.418 mol Ca(ClO₃)₂ *
= 1.254 mol O₂
Finally we <u>convert O₂ moles into grams</u>:
- 1.25 mol O₂ * 32 g/mol = 40.1 g O₂
True. Any cosmetic containing paraffin wax, benzene, mineral oil, PEG, DEA, MEA, the suffix ethyl- or propyl-, etc. About 95% of fragrances contain petrochemicals.
Your answer is correct.
2NaCl(s) ---T--> 2Na(s) + Cl2(g)

The right answer is Radiant energy is converted to stored chemical energy.
Photosynthesis aims to create energy (in the form of carbohydrate) from the light energy from the sun.
Solar energy is used to oxidize water and reduce carbon dioxide to synthesize organic substances (carbohydrates). This phenomenon occurs in chloroplasts, a plant-specific organelle, at the level of the thylakoid membranes where photosystems I and II and cytochromes are located.
