Answer: Option (d) is the correct answer.

Explanation:

In solids, the molecules are held more tightly due to the existence of strong intermolecular forces of attraction between its particles.

Hence, they have a definite shape and volume. So, these molecules are arranged in a regular pattern and they are able to vibrate at their position.

On the other hand in liquids, molecules are slightly away from each other as they are held by less strong intermolecular forces of attraction. Hence, liquids do not have a definite shape but they tend to occupy the shape of container in which they are placed.

Thus, we can conclude that solids maintain their shape, whereas fluids do not because the molecules in solids maintain a regular pattern and only vibrate, or move very slowly.

Solids maintain their shape, whereas fluids do not because the molecules in solids maintain a regular pattern and only vibrate, or move very slowly. The correct option among all the options that are given in the question is the last option or option "d". I hope the answer has come to your help.

Draw a mechanism for the reaction of methylamine with 2-methylpropanoic acid. Draw any necessary curved arrows. Show the product

Nitella [24]

Answer:

See figure 1

Explanation:

On this case we have a base (methylamine) and an acid (2-methyl propanoic acid). When we have an acid and a base an acid-base reaction will take place, on this specific case we will produce an ammonium carboxylate salt.

Now the question is: ¿These compounds can react by a nucleophile acyl substitution reaction? in other words ¿These compounds can produce an amide? 

Due to the nature of the compounds (base and acid), the nucleophile (methylamine) doesn't have the ability to attack the carbon of the carbonyl group due to his basicity. The methylamine will react with the acid-producing a positive charge on the nitrogen and with this charge, the methylamine loses all his nucleophilicity.

I hope it helps!

Water difference between glacier and geyser

Gekata [30.6K]

Glaciers are found in areas where the net accumulation of snow exceeds the melt, therefore they are usually found in areas of high elevation, cold temperatures, and high precipitation.

Geysers are found in areas of shallow crust with high heat flow, such as hot spots.

Avogadro's Number - 6.022 × 10²³ atoms, molecules, formula units, etc.

<h3>Explanation:</h3>

Step 1: Define

50.0 mol H₂O

Step 2: Identify Conversions

Avogadro's Number

Step 3: Convert

$\displaystyle 50.0 \ mol \ H_2O(\frac{6.022 \cdot 10^{23} \ molecules \ H_2O}{1 \ mol \ H_2O} )$ = 3.011 × 10²⁵ molecules H₂O

Step 4: Check

We are given 3 sig figs. Follow sig fig rules and round.

3.011 × 10²⁵ molecules H₂O ≈ 3.01 × 10²⁵ molecules H₂O
