The total volume required to reach the endpoint of a titration required more than the 50 mL total volume of the buret. An initia

Sonja [21]

Answer:

The answer is " $\bold{50.42 \pm 0.08}$ ".

Explanation:

Overall delivered volume $= [(49.06 \pm 0.05) + (1.77 \pm 0.05)]\ mL$

Its blank solution without any of the required analysis $= (0.41 \pm 0.04)\ mL$

Compute the volume of the endpoint as follows:

Formula:

$\text{End point volume = Total Volume delivered - volume required}$

$= (49.06 \pm 0.05) + (1.77 \pm 0.05) - (0.41 \pm 0.04) \\\\= (49.06 + 1.77 - 0.41) \pm \ \ (absolute \ \ uncertainty)$

therefore,

absolute uncertainty $=\sqrt{(0.05)^2 + (0.05)^2 + (0.04)^2}$

$=\sqrt{0.0025 +0.0025 +0.0016} \\ \\=\sqrt{0.0066}\\\\=0.08124\\$

The Endpoint volume $= (49.06+1.77-0.41)\pm (0.08124)$

$= 50.42 \pm 0.08$

Therefore, the volume of the endpoint adjusted for the blank is:

$\bold { = 50.42 \pm 0.08}$

Provide the name(s) for the constitutional isomer(s) with the molecular formula C7H16 that have an unbranched chain. If there is

Tema [17]

Answer:

Explanation:

Isomerism is the occurrence of two or more compounds with the same molecular formula but different structures. Isomers with the same molecular formula and belonging to the same homologous series tends to have similar chemical properties but slightly different physical properties as a result of their constitutional (structural differences).

Thus,as the number of carbon atoms in a molecule increases , the number of isomer also increases. In the given question C7H16 is known as heptane which have nine (9) possible constitutional (structural) isomers.

The main objective is to provide the names for the constitutional isomers with the molecular formula C7H16.

In the attached file below; we've shown the possible isomers of heptane (C7H16). and we've identify them by naming them.

Consider two equal-volume flasks of gas at the same temperature and pressure. One gas, oxygen, has a molecular mass of 32. The o

san4es73 [151]

Answer: The ratio of the number of oxygen molecules to the number of nitrogen molecules in these flasks is 1: 1

Explanation:

According to avogadro's law, equal volumes of all gases at same temperature and pressure have equal number of moles.

According to avogadro's law, 1 mole of every substance contains avogadro's number $6.023\times 10^{23}$ of particles.

Thus as oxygen and nitrogen are at same temperature and pressure and are in equal volume flasks , they have same number of moles and thus have same number of molecules.

The ratio of the number of oxygen molecules to the number of nitrogen molecules in these flasks is 1: 1
