Answer:

i think plumber

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.

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.

They have no odor and no color making them react with water and strong acids to produce salts. They are considered ionic compounds with sodium cation and chloride anion. They also are used in oxide coating and cleaning of metals.

Therefore, option A. plumber will most likely use sodium hydroxide.

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.

Answer:

the last one, (A zinc, Zn, atom contains 30 protons inside the nucleus and 30 electrons outside the nucleus)

A zinc, Zn, atom contains 30 protons inside the nucleus and 30 electrons outside the nucleus accurately describes the atoms of a specific element ,therefore option (d) is correct.

Zinc is placed in group 12 of the periodic table. It is in the first period of transition or d block elements, and fourth period of the periodic table.

Zinc is a metal. It has two valence electrons that are lost easily. Zinc forms positive ions with 2+ charges, like the metals of the alkaline earth family.

So... for the element of SODIUM, you already know that the atomic number tells you the number of electrons. That means there are 11 electrons in a sodium atom. Looking at the picture, you can see there are two electrons in shell one, eight in shell two, and only one in shell three.

Explanation:

Answer:

so there would be 2 electrons because

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.

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.

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.

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.
