Answer:

approx 2.45g

Explanation:

2HCl + Na2SO4 → 2NaCl + H2SO4

 2    :       1           :      2       :      1

0.05                                     0.025 (moles)

⇒ mH2SO4 = 0.025 × 98 = 2.45 g

Rotation about a carbon-carbon double bond does not readily occur because: __________.1) the overlap of the p orbitals of the ca
Advocard [28]

Answer:

1) The overlap of the p orbitals of the carbon-carbon π bond would be lost

Explanation:

Unlike simple bonds, a double bond can not rotate, since it is not possible to twist the ends of the molecule without breaking the π bond.

In the structure of but-2-ene present in the attachment, we can see the two isomers, <em>cis</em> and<em> trans</em>. These isomers cannot be interconverted by rotation around the carbon-carbon double bond without breaking the π bond.

An unknown compound contains 75.69% carbon, 8.80% hydrogen, and 15.51% oxygen by mass. A mass spectrometry analysis reveals that
tiny-mole [99]

Answer:

Molecular formula is C₂₆H₃₆O₄

Explanation:

The compound is 75.69 % C, 8.80 % H and 15.51 % O. This data means, that in 100 g of compound we have 75.69 g, 15.51 g and 8.80 g of, C, O and H, respectively. We know the molar mass of the compound, so we can work to solve the moles of each element.

In 100 g of compound we have 75.69 g C, 15.51 g O and 8.80 g H

In 412 g of compound we would have:

(412 . 75.69) / 100 = 311.8 of C

(412 . 15.51) / 100 = 63.9 g of O

(412 . 8.80) / 100 = 36.2 g of H

Now, we can determine the moles of each, that are contained in 1 mol of compound.

312 g / 12 g/mol 26 C

64 g / 16 g/mol = 4 O

36 g / 1 g/mol = 36 H

Molecular formula is C₂₆H₃₆O₄

How many moles of C2H6 in 3.754 x 1023 molecules of C2H6?
ira [324]

Answer:

n=N/NA

n= 3.754×10²³/6.02×10²³

n= 6.24 s

Explanation

since there is number of molecules, make use of Avogadro's constant to get number of moles.

Explain why ethanol will dissolve in water and carbon tetrachloride will not.
Rama09 [41]
This is because iodine is nonpolar. You also saw that the iodine was less soluble inethanol and acetone than it was in carbon tetrachloride. Ethanoland acetone are more polar thancarbon tetrachloride. Iodine was more soluble in them than it was in water because they are less polar than water.
