Answer:

Ketone is isomeric with an organic compound containing at least one aldehyde group

Explanation:

Isomers have same molecular formula but different functional groups due to variation in positioning of certain atoms within molecules.

Let us consider 1-propanal (contains one aldehyde group). Acetone is isomeric with 1-propanal as both have molecular formula $C_{3}H_{6}O$ . But 1-propanal contains aldehyde (-CHO) functional group and acetone contains keto (-CO-) functional group. Isomerism appears between these two compound due to variable positioning of oxygen atom.

Therefore they are isomeric to each other.

Citric acid is one component of some soft drinks. Suppose that 8 L of solution are made from 0.24 g of citric acid, C6H8O7. What

stealth61 [152]

Answer:

The correct answer is 0.15 × 10⁻³ M.

Explanation:

C₆H₈O₇ is the molecular formula of citric acid. The mass of the one mole of the substance that comprise Avogadro's no of molecules is termed as the molar mass of the substance.

The molar mass of the citric acid (C₆H₈O₇) will be,

6 × atomic mass of carbon + 8 × atomic mass of hydrogen + 7 × atomic mass of oxygen = 6×12 + 8×1 + 7×16 = 192. Thus, the molar mass of citric acid is 192 g/mol.

The value of the solution given in the question is 8 L.

The mass of citric acid given is 0.24 g or 240 mg, which can also be written as 240/1000 g or 240 × 10⁻³ g.

The number of moles can be calculated by using the formula = mass / molar mass. Thus, by putting the values we get,

= 240 × 10⁻³ g / 192 g/mol

= 1.25 × 10⁻³ mol

The number of moles of the solute present in the 1 liter of the solution is termed as the molarity of the solution. The formula of molarity or M is,

= no of moles of solute / volume of solution in L

Now putting the values we get,

= 1.25 × 10⁻³ mol / 8 L

= 0.156 × 10⁻³ M

Hence, the molarity of citric acid in the given solution is 0.15 × 10⁻³ M

1) the average rate of reaction in the first minute

iragen [17]

1. 0+15+30+45+60=150/5=30 s

0+10+16+22+27=75/5=15 cm^3

then, 15/30= 0.5 cm^3/s(average rate of rxn)

2. 0+15+30+45+60+75+90+105+120=540/9=60 s

0+10+16+22+27+31.50+36+39.5+42=224/9=24.89cm^3

then, 24.89/60=0.414cm^3/s (avrg rate of rxn)

3. overall rxn add all the time divide by 12 and the volume add them too and divide by 12. after take average volume divide by the average time to get the average rate of overall rxn

4. 16/30= 0.533cm^3/s

5. 39.5/105= 0.37cm^3/s

Write and balance sodium when it burns in air to form sodium peroxide

Zanzabum

Answer:7.229 grams of oxygen is formed by the complete reaction of 35.23 g of metallic sodium with oxygen at 130–200 °C, a process that generates sodium oxide, which in a separate stage absorbs oxygen: 4 Na + O2 → 2 Na2O. The ozone oxidizes the sodium to form sodium peroxide.

How is Deposition a exothermic reaction?

nikdorinn [45]

<span>all the ones that phase down are exothermic - freezing, deposition, condensation.

all the ones that phase up are endothermic - melting, sublimation, vaporization

endothermic is to gain heat, exothermic is to release heat</span>
