Answer:
3.05 g
Explanation:
The reaction that takes place is:
As the decomposition not necessarily was complete we'll work with the<em> given mass of product formed</em>. We convert <u>the 12 grams of chlorine to moles</u>, using its <em>molar mass</em>:
- 12 g ÷ 70.906 g/mol = 0.169 mol
Then we <u>convert Cl₂ moles to H₂O moles</u>:
- 0.169 mol Cl₂ *
= 0.169 mol H₂O
Finally we <u>convert moles to grams</u>:
- 0.169 mol H₂O * 18 g/mol = 3.05 g
Answer:
Most puppies are born head first but some come tail first. Puppies are born inside a thin sac, which the mother will remove, enabling them to breathe. After each puppy, your dog should pass an afterbirth (placenta), which they often eat.
Explanation:
Total change in energy = Heat produced by system + work done on the system
= 228 - 55
= 173 kJ
Because this energy is released as heat, the reaction is exothermic.
Answer:
I think its False
Explanation:
ozone layer surroundes the atmosphere and traps the heat
Uhh I'm kinda blind so can you hold it a little straight
