3.) Why is argon (Ar) larger than neon (Ne)?​

Answers

Answer: Here u go!

Explanation:

The electron cloud of argon is thus larger and more polarized, able able to express mawr inter molecular forces Vander Waals forces, which results in a higher boiling point due to these increase forces. Due to this, the boiling point of argon is higher are gone. We can see its boiling point is 87.2 Kelvin's, whereas a neon and spoiling point is 24.5.

Hope this helps!

Explanation:

Argon has an atomic number of 18, while neon has an atomic number of 10.

The atomic radius is comprised of the atom’s nucleus and electron cloud. As you go down on the periodic table, the effective nuclear charge decreases. This results in more screening of the electrons

from the nucleus (decreasing the attraction between the nucleus and the electrons) resulting in a larger atomic radius.

However, because they’re both noble gasses, the size difference in this case can be easier described by the number of particles in each atom.

Argon has 18 protons, 18 electrons and 22 neutrons.

Neon has 10 protons, 10 electrons and 10 neutrons.As you can see, argon has more “stuff.”

The increase in protons and electrons in particular results in a larger electron cloud, which means a much larger atomic radius than in neon.

A pizza is an example of a heterogeneous mixture. Explain why it is classified as such?​

Answers

Answer:

Hi!

So, a homogeneous mixture is when the parts that make up the mixture are all mixed in perfectly evenly, so they're only appearing as one uniform substance.

In a heterogeneous mixture, the pieces are not evenly mixed. A pizza has separate parts, like the crust and toppings, so it's a heterogeneous mixture.

Sodium hydroxide is generally referred to as caustic soda used in soaps and cleaners. A plumber would most likely be required to work with sodium hydroxide. Hence, option A is correct.

What is the use of sodium hydroxide?

Soaps, paper, explosives, dyes, and petroleum are all made with sodium hydroxide. The presence of sodium hydroxide in a cleanser or a homemade aqueous solution converts these disconcerting fats into soaps, which are easily removed by water.

Which of the following is true for polar jet streams?

They bring cool air.
They bring warm air.
They blow at the equator.
They blow from north to south.

Answers

Answer:

A: They bring cool air.

Explanation:

Took the test and got it correct. :)

Jet streams are fast flowing meandering air currents. Polar jet streams bring cool air through the atmosphere. Polar jets meet subtropical jets at some regions.

What are polar jet streams ?

The polar jet stream, which travels through the lower layers of the atmosphere in the Northern Hemisphere, is a swiftly moving band of westerly winds.

The confluence of warm air ascending from the tropics and cold air masses descending from the arctic produces the jet. The denser cold air lowers and deflects the warmer air areas north, creating deep troughs and steep ridges that give the jet stream its wavy appearance.

As pockets of cold air intermittently sneak down from the Arctic, this pattern spreads across the mid-latitudes of North America, Europe, and Asia, producing opposing waves and flows that speed eastward due to the earth's rotation.

A student titrates 0.1719 g of an unknown monoprotic acid to the equivalence point with 21.85 mL of 0.1062 M NaOH. Which of the following is most likely to be the unknown acid? propionic acid (MM 74.08 g/mol) nitrous acid (MM 47.01 g/mol) chlorous acid (MM 68.46 g/mol) benzoic acid (MM 122.12 g/mol) lactic acid (MM: 90,08 gimol)​

Answers

Answer:

Propionic acid

Explanation:

Step 1: Write the generic neutralization reaction

HA + NaOH ⇒ NaA + H₂O

Step 2: Calculate the reacting moles of NaOH

21.85 mL of 0.1062 M NaOH react.

0.02185 L × (0.1062 mol/L) = 2.320 × 10⁻³ mol

Step 3: Calculate the reacting moles of HA

The molar ratio of HA to NaOH is 1:1. The moles of HA are 1/1 × 2.320 × 10⁻³ mol = 2.320 × 10⁻³ mol.

Step 4: Calculate the molar mass of HA

0.1719 g of HA correspond to 2.320 × 10⁻³ moles.

MM = 0.1719 g/2.320 × 10⁻³ mol = 74.09 g/mol

With this molar mass, the most likely acid is propionic acid.

Why does a small pebble sink in water?

Answers

a small pebble may sink in water because it’s mass might not be that great but is the weight that matter and of it weights more than 1.0g/cm^3 (density of water)

A small pebble sinks in water because its density is greater than the density of water. Density is a measure of how much mass is packed into a given volume. If an object is denser than the liquid it is placed in, it will sink.

When a pebble is dropped into water, the water exerts an upward force called buoyancy. This force opposes the weight of the pebble, and if the pebble is less dense than water, it will experience an upward force greater than its weight and float.

However, if the pebble's density is greater than that of water, the downward force due to its weight will be greater than the upward buoyant force, causing it to sink.
