Calcium carbonate is indeed used as an antacid (among Mg(OH)2, Al2(OH)3 and NaHCO3).

Ferrous oxide or Iron (II) oxide is a dark substance, and I would certainly think twice before using a dark tooth paste (Yew! ) It might even rust if left in the mouth for some time!

<h3><u>Answer;</u></h3>

B) Swap the uses for iron oxide and calcium carbonate.

<h3><u>Explanation;</u></h3>
  • Calcium carbonate is a compound that is naturally found in marble, chalk and limestone. It is used in pharmaceutical applications as a cost <u>effective dietary calcium supplement, and also used in antacids.</u>
  • Calcium carbonate is also found in <u>products such as baking powder, tooth paste, and wine among others.</u>
  • Iron oxides are compounds of iron that are<u> used as coloring agents in some cosmetics.</u> The forms of iron oxides used in cosmetics are normally synthetic.

Which of the following best describes an orbital?
Debora [2.8K]

Answer:

a) a space in an atom where an electron is most likely to be found

Explanation:

Atomic orbital is the mathematical function which describes wave-like behavior of the electrons present in the atom.

It is used to calculate probability of finding the electron of the atom in any  region around nucleus of the atom. Atomic orbital is the physical region or a three dimensional space where the probability of finding the electron is more than 90% which also means that the space where an electron is most likely to be found. They are boundless space and have definite energy.

Option A best describes atomic orbital.

The atmosphere of the planet Mars is 95.3% carbon dioxide, 2.6% nitrogen, 1.9% argon, with the remaining fraction being traces o
kodGreya [7K]

Answer:

Mean Partial pressure of Nitrogen in Mars' atmosphere = 15.86 Pa

Explanation:

According to Dalton's law of Partial Pressure, the total pressure exerted by a mixture of ideal gases (that do not react together) is the sum of the partial pressures of the individual gases that make up the mixture. It goes further to explain that the partial pressure of a gas in a mixture of gases is equal to its mole fraction of that gas multipled by the total pressure exerted by the mixture of gases.

Total Pressure exerted by the mixture of gases in the atmosphere on Mars = Mean atmospheric pressure on Mars = 610 Pa

Partial pressure of Nitrogen = (mole fraction or mole percentage of Nitrogen in the atmosphere) × (total pressure exerted by all the gases in the atmosphere)

Mole percentage of Nitrogen in the atmosphere of Mars = 2.6%

Partial pressure of Nitrogen = 2.6% × 610 = 15.86 Pa

Mean Partial pressure of Nitrogen in Mars' atmosphere = 15.86 Pa

Hope this Helps!!!
