Answer:

Explanation:

Chemical properties:

These are the properties which involve the chemical reaction.

For example:

Combustion, flammability, toxicity, enthalpy of formation etc are chemical properties.

Reaction with oxygen ( chemical property)

Conduction of heat ( chemical property)

Not flammable (chemical property)

Physical properties:

The property which not involve any chemical reaction it only involve the physical appearance of substance.

For example:

Density, odor, color, texture etc.

Smooth texture (physical property)

Reddish color ( chemical property)

Sink in water ( chemical property)

How many grams of iron (3)sulfide are produced when 131 grams of iron react with excess sulfur?

Tomtit [17]

<u>We want the molar mass (gfm) of Fe and FeS.</u>

Fe = 55.8 g/mol and FeS = 87.8 g/mol (55.8 +32.0).

<u>Explanation:</u>

We want ratio between Fe:FeS 8:8. This comes from the coefficients of the equal chemical equation.

Now we set up conversion factors following the roadmap from above.

Unit we want in the numerator, unit to cancel in the denominator.

Multiply the numerators, and divide the denominators.

$(131.0)gFe \times 1molFe/(55.8)gFe \times 8molFeS/8molFe \times 87.8gFes/1molFes$

$243.82 g \ of Fe_2S_3$

The outcome is 243.82 g of ferrous sulphite

By the above given formula we can find any amount of Fes produced by any amount of ferrous react with sulphite.

At which temperature would a can of soda be most fizzy when it is opened?

kati45 [8]

Answer: at higher temperatures.
Justification:

1) Soda have CO₂ dissolved. Carbonation consists on that: dissolving CO₂ into water, leading to carbonated water.

2) The solution of a gas into a liquid is inversely related to the temperature: the lower the temperature the more gas gets dissolved.
So, in the manufacturing of soda, the CO₂ is added in cool water in a cool environment.

3) So, the higher the temperature after the soda is delivered, the more gas will be liberated when you open the can.

) Predict the product for the following reaction sequence. A) 2,2-dimethylpropanoic acid B) 3,3-dimethyl-2-butanone C) 2,2-dimet

cestrela7 [59]

Answer:

Option C. 2,2-dimethyl-1-propanol

Explanation:

The first attached picture, is the initial reactant.

Now, what happens in each step?, at first we have an alkyl bromide reacting with Mg/ether. This converts the reactant in a grignard reagent, which is often used in several ketones/ladehydes reactions, and even some acid and esthers.

Now, in the second step, we see this grignard reagent, reacting with CO₂ and H₃O⁺. At first, the grignard reagent will attach to the oxygen of the CO₂ by the MgBr, and the carbonated chain will attach to the carbonile. Then in acid medium, the OMGBr leaves the molecule, and form a carboxylic acid.

Finally, in the last step with LiAlH₄ and water, this compound just reduces the carboxylic acid to a primary alcohol, therefore, the only choice available is option c, 2,2-dimethyl-1-propanol.

See picture 2 below for the drawing.

Hope this helps
