A common fuel additive that is composed of C, H, and O enhanced the performance of gasoline began being phased out in 1999 becau

se of its contamination of drinking water. When 12.1 g of the compound are burned, 30.2 g of CO2and 14.8 g of H2O are formed. What is the empirical formula of the compound?

Answer:

C₅ H₁₂ O

Explanation:

44 g of CO₂ contains 12 g of C

30.2 g of CO₂ will contain 12 x 30.2 / 44 = 8.236 g of C .

18 g of H₂O contains 2 g of hydrogen

14.8 g of H₂0 will contain 1.644 g of  H .

total compound = 12.1 out of which 8.236 g is C and 1.644 g is H , rest will be O

gram of O = 2.22

moles of C, O, H in the given compound =  8.236 / 12 , 2.22 / 16 , 1.644 / 1

= .6863 , .13875 , 1.644

ratio of their moles = 4.946 : 1 : 11.84

rounding off to digits

ratio = 5 : 1 : 12

empirical formula = C₅ H₁₂ O

Every reduction reaction MUST be accompanied by
Dafna1 [17]

Answer:

oxidation reaction.

Explanation:

Every reduction reaction must be accompanied by an oxidation reaction.

Oxidation leads electrons loss whereas reduction implies gain of electrons. So missing electrons should always be the equivalent of obtained electrons. Without something acquiring electrons there can't be any loss. Electrons can't simply disappear!

It implies, but, that oxidation and reduction must occur simultaneously at different locations and the electrons can commute across cables or in a liquid medium by ions.

Draw the addition products formed when one equivalent of HBr reacts with 2,4-hexadiene. (Draw a single product for each. Ignore
Tems11 [23]

Answer:

The products are 4-bromo-2-hexene and 2-bromo-3-hexene

Explanation:

The reaction starts between terminal carbon of of of the double bonds and H^{+}. After attaching H^{+} to the carbon, one double bond disapears leaveing nearby CH positively charged. This intermediate is a resonance hybrid of two possible structures. Reaction of bromide at one of the carbons gives the 1,2-addition product and at the other carbon gives 1,4-addition product.

Answer:

Judges and justices serve no fixed term — they serve until their death, retirement, or conviction by the Senate. By design, this insulates them from the temporary passions of the public, and allows them to apply the law with only justice in mind, and not electoral or political concerns.

Type the correct answer in the box. express your answer to three significant figures. an air mattress is filled with 0.55 moles
dmitriy555 [2]

385 L is the volume of the air mattress with 0.55 moles of air inside the mattress and a temperature of 295 K.

<h3>What is an ideal gas equation?</h3>

The ideal gas law (PV = nRT) relates to the macroscopic properties of ideal gases. An ideal gas is a gas in which the particles (a) do not attract or repel one another and (b) take up no space (have no volume).

Using the gas law,

PV=nRT, where n is the moles and R is the gas constant. Then divide the given mass by the number of moles to get molar mass.

Given data:

P= 3.5 kPa

V=?

n= 0.55 moles of air

T= 295K

R= 8.314 (L kPa/mol K)

Putting value in the given equation:

V= \frac{nRT}{P}  

V = \frac{(0.55 moles)(8.314 L kPa/mol k)(295 K)}{3.5 kPa}

V = 385.4132857 L

And whatever the significant figure is asked for, for example, 3 significant figures: the answer would be 385 litres.

Hence, 385.4132857 L is the volume of the air mattress.
