Answer:
A. It is in the gas phase.
Explanation:
it was correct on ap3x :)
Answer:
The molecules in a gas are very far apart so they can be squeezed together into a smaller space.
Answer is: <span>the winning recipe.
</span>An appositive is a noun<span> or </span>noun phrase<span> that renames another noun right beside it. The appositive can be a short or long combination of words.
</span>Another example: Problem number 19, the final question, was difficult - the final question is<span> the appositive phrase in this sentence.</span>
A double replacement is when the reactants switch with their opposite charge. For example, AB + CD = AD + BC.
In this case the given is K2SO4 + Pb(NO3)2 = ____ + ____
The answers is PbSO4 and KNO3 would expect the products of this reaction.
Answer:
In the calorimeter, water is the <u>exothermic</u>. The salt LiCI, which will dissolve, is the <u>endothermic</u>. The final temperature of the water after the dissolution of LiCI was <u>lower</u> than the initial temperature, meaning the process is <u>exothermic</u>. In the microscopic view of the disspolution of LiCI, water molecules were seen to move <u>slowly</u> as they <u>gained </u>energy.
Explanation:
Exothermic is a process in which heat is released during the process. Endothermic reactions absorbs heat from surrounding during a chemical process. The dissolution of salt into water is an exothermic reaction. During this process heat is release and water molecules are broken down which are surrounded by salt ions.
