Answer:
It changes into a liquid because when it gets heated up to a certain temperature, it reaches it's "boiling point", which is when it will start to transform into a liquid because the temperature is too hot for it to remain a solid.
Explanation:
Just think of when icicles melt because of the sun. The sun is heating them up and it gets too warm to the point that it liquidizes.
Answer: 
, 
, NaOH are all ionic compounds.
Explanation:
It is known that ionic compounds are the compounds in which one atom transfer its valence electrons to another atom. Hence, during this transfer partial opposite charges tend to develop on the combing atoms due to which strong force of attraction exists between the atoms.
An ionic bond is always formed between a metal and a non-metal.
For example, , , NaOH are all ionic compounds.
On the other hand, a compound formed due to sharing of electrons between the combining atoms is known as a covalent compound. Generally, a non-metal with same or different non-metal tends to form a covalent bond.
For example, 
, 
etc are all covalent compounds.
Thus, we can conclude that , [tex]CH_3CH_2COONa, NaOH are all ionic compounds.
Answer:
Lithium chloride (LiCl), carbon dioxide, and water
Explanation:
Li₂CO₃ + HCl ⇒ LiCl + CO₂ + H₂O
When lithium carbonate reacts with hydrochloric acid, lithium chloride, water, and bubbles of carbon dioxide gas are given off. This is the result of a double displacement reaction followed by a decomposition reaction.
Hope that helps.
Here you go I think that's an answer
Answer:
3.36L
Explanation:
From a background study of gas laws together with the gases, it has been proven that 1 mole of a gas occupy 22.4L at stp.
This means that 1 mole of CO2 occupies 22.4L.
Therefore, 0.15 mol of CO2 will occupy = 0.15 x 22.4 = 3.36L
From the calculations made above, 0.15 mole of CO2 will occupy 3.36L
