People in the United States know that water boils at 212 degrees Fahrenheit. In Europe, people know that water boils at 100 degr

ees Celsius. Is the water in the U.S. different than the water in Europe? What explains the two different temperatures?

No, the water is not different it is just that the units of measurement in the US is different then those units in Europe. This is similar to how the US uses miles and Europe uses kilometers

A cucumber is placed in a concentrated salt solution. What will most likely happen? Select one: a. Water will flow from the cucu
antiseptic1488 [7]

Answer:

a.- Water will flow from the cucumber to the solution

Explanation:

This is an example of osmosis in difference of concentration of solutions. In the salty solution there is more salt molecules than inside the cucumber. Trying to make up for the same salt concentration inside that outside the cucumber, it will tend to flow some of the water that is inside the cucumber tissues to the environment that surrounds it.

Which has the strongest conjugate base?
aleksandr82 [10.1K]

Answer:

Phenol.

Explanation:

Hello there!

In this case, for this question about the strength of the resulting conjugate base, it is possible for us to know that the higher the Ka (stronger aid) the weaker the conjugate base. In such a way, since the phenol has the smallest Ka (weakest acid) we infer that it has the strongest conjugate base.

In addition to the aforementioned, the reason why phenol was the answer is because the Kb of its conjugate base is the greatest due to the Kb=Kw/Ka and thus, the smaller the Ka the bigger Kb.

Regards!

Balance the following Equation:
lisabon 2012 [21]

Answer:

HCl is the limiting reactant. It will completely be consumed (1.37 moles)

Option D is correct

Explanation:

Step 1: Data given

Mass of Zinc (Zn) = 50.0 grams

Mass of Hydrogen chloride (HCl) = 50.0 grams

atomic mass Zn = 65.38 g/mol

Molar mass HCl = 36.46 g/mol

Step 2: The balanced equation

Zn + 2HCl → ZnCl2 + H2

Step 3: Calculate moles

Moles = mass / molar mass

Moles Zn = 50.0 grams / 65.38 g/mol

Moles Zn = 0.764 moles

Moles HCl = 50.0 grams / 36.46 g/mol

Moles HCl = 1.37 moles

Step 4: Calculate limiting reactant

For 1 mol Zn we need 2 moles HCl to produce 1 mol ZnCl2 and 1 mol H2

HCl is the limiting reactant. It will completely be consumed (1.37 moles)

Zn is in excess. There will react 1.37/2 = 0.685 moles

There will remain 0.764 -0.685 = 0.079 moles

Given the molecules diethyl ether (CH₃CH₂OCH₂CH₃) and 1-butanol (CH₃CH₂CH₂CH₂OH), __________ has the higher boiling point mainly
MArishka [77]

Answer:

1-butanol has higher boiling point mainly due to presence of hydrogen bonding.

Explanation:

Diethyl ether is a polar aprotic molecule due to presence of polar C-O-C moiety. Hence only dipole-dipole intermolecular force exist between diethyl ether molecules.

1-butanol is a polar protic molecule due to presence of C-OH moiety. Therefore dipole-dipole force along with hydrogen bonding exist between 1-butanol molecules.

So, intermolecular force is higher in 1-butanol as compared to diethyl ether. Hence more temperature is required to break intermolecular forces of 1-butanol to boil as compared to diethyl ether.

So, 1-butanol has higher boiling point mainly due to presence of hydrogen bonding.

Zn(s) + 2HCl(aq) → ZnCl2(aq) + H2(g)
ZanzabumX [31]

Answer:

limiting reactant

Explanation:

<em>The term that will be used to describe zinc in this case is </em><em>limiting reactant.</em>

A limiting reactant is a reactant that determines the amount of product formed in a chemical reaction. They are often stoichiometrically smaller of all the reactants in a reaction and once they are used up during, the reaction stops.

In this case, the zinc metal in the reaction is completely consumed, making the hydrochloric acid to be in excess. The zinc thus determines the amount of the products formed,
