Answer:
Travis categorized their characteristics correctly.
Explanation: This is because plants use chloroplast in their cells to help them with photosynthesis, and this is what turns them green. Animals do not make their own food so they have no use for chloroplast in their cells.
Yes it is pairs of electrons with two shared molecules
Answer:
B. False
Explanation:
the reaction is
H₂0 + O₂ = H₂O
as addition of oxygen means burning in the system which means heating or energy is necessary for the reactants. SO the reaction is spontaneous and exothermic .
As according to second law of thermodynamics
the change in enthalpy is greater than or equal to zero when the reaction is spontaneous, so enthalpy will increase in the above reaction.
H2 burning in O2 to form H2O (l) is an example of a system where the entropy of the universe increases.
Stirring affects how quickly a solute dissolves in a solvent, but has no effect on how much solute will dissolve. The amount of solute that will dissolve is affected by temperature - more will dissolve at higher temperatures. This is called the solubility of the solute
Explanation:
An apple pie is a mixture whereas lead iodide is a compound. To processes leading to the formation of a mixture and a compound are completely different.
- A compound is a substance composed of two or more kinds of atoms that are joined together to form a definite matter.
- The properties of the compound formed differs from that of the constituent atoms.
- A mixture on the other hand is made up of indefinite compositions.
- In the case of the apple pie, the parts are not homogeneous in nature.
To produce lead iodide, chemical reactions must take place between atoms.
In the case of the pie, chemical and physical changes can take place.
