Ummm...
WHat is this? What do you want us to do??
Answer:
C
Explanation:
Li, Na+, K+ are all having the same number of electrons
Answer: Increasing the volume of the gas would be the correct answer. Charles law of gas states this: 1) If the volume of a container is increased, the temperature increases.
2) If the volume of a container is decreased, the temperature decreases.
Hope this helps
Explanation:
Answer:
1. molecular
2. molecular
3. molecular
Explanation:
Molecular compounds typically exhibit covalent compound characteristics. They are pure substances formed when atoms are linked together by sharing electrons while ionic compounds are formed due to the transfer of electrons. Molecular substances tend to melt at moderately warm temperatures (i.e. 50° C) and it is overlapping as seen in compound 1, which makes it to be molecular in nature.
Molecular compounds are not affected by conductivity, hence they are electrically neutral.
Molecular compounds have a strong smell and have freezing and boiling point at accessible temperatures. A clear liquid at room temperature which has a fruity strong smell can be an organic compound. These organic compounds made up of covalent bonds and are molecular in nature.
Explanation:
A chemical reaction is defined as the reaction which leads to change in chemical composition of the reactants due to which there occurs formation of a new compound.
For example, when Ethan heats a substance and observes that the substance turns from a brown solid to a black powder then it means heating has lead to a chemical change in the brown solid because of which it has turned into a black powder.
Whereas if there occurs no change in chemical composition of the reactants then we can say that a physical change has occurred.
For example, change in shape, size, mass etc of a substance are all physical changes.
Hence, we can conclude that Ethan best defend his conclusion as a chemical change.
