Groundwater varies between each year and state. Although from this map it seems as though the southeast part of the US contains more groundwater than other states. While the southwest and west side of the US does not contain as much groundwater as other states.

Dehydrohalogenation of 1-chloro-1-methylcyclopropane affords two alkenes (A and B) as products.
UNO [17]

Explanation:

Dehydrohalogenation reactions occurs as elimination reactions through the following mechanism:

Step 1: A strong base(usually KOH) removes a slightly acidic hydrogen proton from the alkyl halide.

Step 2: The electrons from the broken hydrogen‐carbon bond are attracted toward the slightly positive carbon (carbocation) atom attached to the chlorine atom. As these electrons approach the second carbon, the halogen atom breaks free.

However, elimination will be slower in the exit of Hydrogen atom at the C2 and C3 because of the steric hindrance by the methyl group.

Elimination of the hydrogen from the methyl group is easier.

Thus, the major product will A

A helium balloon has a volume of 735 mL when it is at ground level. The balloon is
bagirrra123 [75]

Answer:

The answer to your question is P1 = 1.4 atm

Explanation:

Data

Volume 1 = V1 = 735 ml

Pressure 1 = P1 = ?

Volume 2 = V2 = 1286 ml

Pressure 2 = P2 = 0.8 atm

Process

To solve this problem use Boyle's law.

          P1V1 = P2V2

-Solve for P1

          P1 = P2V2 / V1

-Substitution

          P1 = (0.8 x 1286) / 735

-Simplification

          P1 = 1028.8 / 735

-Result

          P1 = 1.4 atm

How is the periodic table used to predict the properties of an element?
Novosadov [1.4K]
There are many ways to predict the properties of an element here's one example.As you move from left to right the electron affinity and ionization  energy both increase .Since elements of the same family have similar characteristic,you can often  predict the properties of another element in its family

Consider the reaction of 35.0 g of iron as follows:
77julia77 [94]

Explanation:

4Fe + 3O2 --> 2Fe2O3

Mass of  iron = 35g

<em>How many moles of iron react?</em>

The relationship between mass and moles is given as;

Moles = mass /  Molar mass

Molar mass of iron = 56g/mol

Number of moles = 35 / 56 = 0.625 mol

<em>How many moles of oxygen molecules must react?</em>

From the equation of the reaction;

4 mol of Fe reacts with 3 mol of Oxygen molecule

0.625 mol would react with x mol?

4 = 3

0.625 = x

x = 0.625 * 3 / 4 = 0.46875 mol

<em>How many moles of product form?</em>

From the equation of the reaction;

4 mol of Fe reacts to form 2 mol of Fe2O3

0.625 mol would form x mol of Fe2O3

4 = 2

0.625 = x

x = 0.625 * 2 / 4 = 0.3125 mol

<em>What mass of product forms?</em>

Moles = mass /  Molar mass

Mass = Molar mass * Moles = 159.69 g/mol * 0.3125 mol = 49.9g
