Answer:

Symmetrical and non polar

Explanation:

H- C = C- H is a symmetrical, non polar molecule since it is linear and the arrangement of the atoms is the same on both sides of the triple bond.

Answer:

B) Symmetrical and nonpolar

Step-by-step explanation:

The formula is H-C≡C-H.

Each C atom has two electron regions, so VSEPR theory predicts a linear molecular geometry (see image below).

The molecule is symmetrical, because the green line divides the molecule into two halves that are mirror images of each other.

The C-H bonds are slightly polar, because C is more electronegative than H (µ ≈ 0.4 D).

The C atoms are partially negative (red), while the H atoms are partially positive (blue).

However, the two C-H bond dipoles point in opposite directions, so they cancel each other. The molecule has no net dipole moment.

Acetylene is nonpolar.

Answer:

(S)-3-methoxy-3-methylbutan-2-ol

Explanation:

In this case, we have an epoxide opening in acid medium. The first step then is the protonation of the oxygen. Then the epoxide is broken to generate the most stable carbocation. The nucleophile ( $CH_3OH$ ) will attack the carbocation generating a new bond. Finally, the oxygen is deprotonated to obtain an ether functional group and we will obtain the molecule (S)-3-methoxy-3-methylbutan-2-ol.

See figure 1

How do dominant genes and recessive genes affect taste?

kherson [118]

Answer:

Explanation:

Because it is genetic, taste is thus inherited based on the allele combination, or “to taste, or not to taste”. The ability is highlighted here; the ability to taste PTC shows a dominant pattern of inheritance. A single copy of a tasting allele (T) conveys the ability to taste PTC.

What is the density of lithium metal (in g/cm3) if a cube measuring 0.82 cm × 1.45 cm × 1.25 cm has a mass of 0.794 g?

Maksim231197 [3]

Density is given by mass divided by the volume of a substance.
In this case the mass is 0.794 g and the volume is 0.82 cm ×1.45 cm ×1.25 cm = 1.48625 cm³.
Therefore, density = 0.794/ 1.48625
= 0.5342 g/cm³
Thus, the density of lithium metal is 0.5342 g/cm³

If 5.4 g of NaNO3 is dissolved in 350 mL of water, what is the molarity of the solution?

Aleonysh [2.5K]

Answer:

0.18 Moles

Explanation:

first you need to convert the 5.4g to moles using molar mass

$(\frac{5.4g}{1})(\frac{1mol}{84.99g} )=\frac{5.4g}{84.99g} =0.0635mol NaNO_{3}$ )
