natulia [17]3 years ago
4 0

Answer:

When isolated as a free element, chlorine takes the form of a greenish-yellow gas, which is 2.5 times heavier than air and smells like bleach. Chorine is the second-most-abundant halogen and the second-lightest halogen on Earth, after fluorine

A housewife purchases a 3.0 lb. roast, what is its weight in grams
Afina-wow [57]

The weight of the 3 lb roast purchased by the housewife is 1,360.78 grams.

<h3>What is weight?</h3>

The weight of an object is the force acting on the object due to gravity.

The weight of an object varies from place to place across the globe due to difference in acceleration due to gravity.

<h3>Weight of the roast in grams</h3>

1 lb ------------> 453.592 grams

3 lb ------------> ?

= (3 x 453.592)

= 1,360.78 grams

Thus, the weight of the 3 lb roast purchased by the housewife is 1,360.78 grams.

A generic element, Z, has two isotopes, 45Z and 47Z, and an average atomic mass of 45.36 amu. The natural abundances of the two
Dmitry_Shevchenko [17]

Answer:

46.96 amu

Explanation:

Isotopes are different kinds of same elements. The difference between two isotopes of the same element is the number of neutrons.

To get the relative atomic mass, we take into consideration the masses of the different isotopes. This is done by multiplying their abundances by their masses. They are then added together to get the relative atomic mass of the element.

Let the isotopic mass of 47Z be x

45.36 = [80/100 * 44.96] + [20/100 * x]

45.36 = 35.968 + 0.2x

0.2x = 45.36 - 35.968

0.2x = 9.392

x =9.392/0.2 = 46.96 amu

Potassium bromide conducts electricity when ______
amm1812

Answer:

When melted or dissolved in water.

Explanation:

Potassium bromide in its solid form contains ions, which are charged atoms. Through the heating process, the melted potassium bromide becomes an ionic liquid. If solid potassium bromide is dissolved, for example in water, the resulting release of ions allows it to conduct electricity.

How many miles of iron can be produced from 3.5 moles of Fe2O3 and 6.2 moles of CO
AlekseyPX

Answer:

4.13 moles of Fe.

Explanation:

Given data:

Moles of iron produced = ?

Moles of Fe₂O₃ = 3.5 mol

Moles of CO = 6.2 mol

Solution:

Chemical equation:

Fe₂O₃ +  3CO      →    2Fe + 3CO₂

Now we will compare the moles of iron with CO and Fe₂O₃.

                 Fe₂O₃        :         Fe

                      1             :          2

                  3.5             :         2/1×3.5 = 7 mol

                 CO              :          Fe

                   3               :            2

                 6.2              :        2/3×6.2 = 4.13 mol

The number of moles of iron produced by CO are less it will limiting reactant.

Thus, moles of iron formed in given reaction are 4.13 moles.

Treatment of ethyl acetoacetate with NaOEt (2 equiv) and BrCH2CH2Br forms compound X. This reaction is the first step in the syn
valkas [14]

Answer:

See explanation below

Explanation:

In this reaction we have the ethyl acetoacetate which is reacting with 2 eq of sodium etoxide. The sodium etoxide is a base and it usually behaves as a nucleophyle of many reactions. Therefore, it will atract all the acidics protons in a molecule.

In the case of the ethyl acetoacetate, the protons that are in the methylene group (CH3 - CO - CH2 - COOCH2CH3) are the more acidic protons, therefore the etoxide will substract these protons instead of the protons of the methyl groups. This is because those hydrogens (in the methylene group) are between two carbonile groups, which make them more available and acidic for any reaction. As we have 2 equivalents of etoxide, means that it will substract both of the hydrogen atoms there, and then, reacts with the Br - CH2CH2 - Br and form a product of an aldolic condensation.

The mechanism of this reaction to reach X is shown in the attached picture.
