Answer:

Quantitative= The candle is 3 inches tall and has a diameter of 2 inches.

Qualitative=  odor, cold, hot, taste, texture, and appearance

Explanation:

Qualitative:

Qualitative properties are those that can be only observed but not measured in numerical values. These are observed through senses: touch, sight, smell, taste and hear.

For example:

Color, odor, brittleness, taste etc.

Quantitative:

Quantitative properties can be measured in numerical values.

For example:

Melting point, boiling point, conductivity, viscosity, density, hardness and solubility.

In short we can say that qualitative is a measure of quality while the quantitative is a measure of quantity.

Can someone help me with this please!
Kryger [21]
<span>Step 1: Convert the given amount to moles, by dividing the given amount by the molecular weight of the compound. 

5 g C3H8 (1 mol / 44 g C3H8) = 0.114 mol C3H8 

Step 2: Find the mole ratio between the given and the desired target (in this case water). The mole ratio between C3H8 and water is 1:4, that is, you can make 4 times as much water from a one C3H8 (assuming that it isn't the limiting reactant). 

0.114 mol C3H8 (4 moles H2O / 1 mol C3H8) = 0.456 mol H2O 

Step 3: Reconvert back to grams by multiplying by the molecular weight of the new target (water). 

0.456 mol H2O (18 g / 1 mol H2O) = 8.208 g Water. Hope this helped! :) </span><span />

Why krypton and noble gas are not used in airships using the periodic table?
WITCHER [35]

Answer:

Since the noble gases are unreactive or inert, they are safe to use. Helium is used to fill balloons and airships, because it is much lighter that air and it will not catch fire. Neon is used in advertising signs. It will give red glow, but the color can be changes by mixing it with other gases.

Dehydration of 2-methyl-2-pentanol forms one major and one minor organic product. Draw the structures of the two organic product
Korvikt [17]

Answer:

The major product is 2-methyl-2-pentene [ CH₃-CH₂-CH=C(CH₃)₂ ] and a minor product 2-methyl-1-pentene [ CH₃-CH₂-CH₂-C(CH₃)=CH₂ ].

Explanation:

Dehydration reaction is a reaction in which a molecule loses a water molecule in the presence of a dehydrating agent like sulfuric acid (H₂SO₄).

<u>Dehydration reaction of 2-methyl-2-pentanol</u> gives a major product 2-methyl-2-pentene and a minor product 2-methyl-1-pentene.

CH₃-CH₂-CH₂-C(CH₃)₂-OH (2-methyl-2-pentanol)→ CH₃-CH₂-CH=C(CH₃)₂ (2-methyl-2-pentene, major) + CH₃-CH₂-CH₂-C(CH₃)=CH₂ (2-methyl-1-pentene, minor)

<u>Since more substituted alkene is more stable than the less substituted alkene. So, the trisubstituted alkene, 2-methyl-2-pentene is more stable than the disubstituted alkene, 2-methyl-1-pentene.</u>

<u>Therefore, the trisubstituted alkene, 2-methyl-2-pentene is the major product and the disubstituted alkene, 2-methyl-1-pentene is the minor product.</u>
