<u>Answer:</u> The mass of produced will be 8.228 g.
<u>Explanation:</u>
We need to find the mass of carbon dioxide produced when 150 kJ of heat is released.
For the given chemical reaction:
By Stoichiometry of the reaction:
802.3 kJ of energy is released when 1 mole of carbon dioxide is produced.
So, 150 kJ of energy will be release when = of carbon dioxide is produced.
To calculate the mass of carbon dioxide, we use the equation:
Moles of carbon dioxide gas = 0.187 mol
Molar mass of carbon dioxide gas = 44 g/mol
Putting values in above equation, we get:
Hence, the mass of produced will be 8.228 g.
Answer:
Posible dimers structures: B) and D) (Figure 1)
Explanation:
The correct <u>dimer structures</u> are the ones that have a right <u>intermolecular bonding</u> interacction. In this case we will have hydrogen bonding. This type of interaction is due to the negative polarization in the oxygen and the positive polarization in the hydrogen. (Figure 2)
So, a correct dimer structure is posible if we have an interaction from the negative part (oxygen) to the positive part (hydrogen). The only structures that have this type of interactions are B and D.
