A., I believe. It's either an ionic, covalent, or hydrogen bond
Answer:
Double replacement.
Explanation:
Chemical Reactions => Double Replacement Reactions.
Let's call Ted as T, Emily as E, Jack as J, and Brenda as B.
In the first match, we have T and E playing against J and B; and in the second match, we have T and B playing against J and E. We can state a 'reaction' of this if the first match would be the reactants and the second match the products:

You can note that this is similar to a double replacement reaction, remember that a double-replacement reaction is a reaction in which the positive and negative ions of two ionic compounds exchange places to form two new compounds. The general form of a double-replacement reaction is:

which is similar to the reaction of the game, so the answer would be Double replacement.
1 mole contains 6.023 *10^23 molecules
Answer: 2-Pentene
Explanation:
The longest continuous carbon chain that contains the double bond is identified to be Pentene, since it has five carbon atoms.The presence of the double bond makes it an Alkene, hence the -ane ending of the parent Alkane is changed to -ene.
We then do our numbering in the direction that gives the position of the double bond a lower number. Numbering from right to left, the position of the double bond is at carbon atom 2 going to 3, which is lower compared to the other direction.
Hence the name of the compound is 2-Pentene.
The rate of evaporation would decrease because of
the formation of bonds between the soap and the water.
So, no. Regular water evaporates faster than soapy water
