How many moles are present in 4.7 liters of Argon gas at STP?
Answers
The answer for the following problems is mentioned below.
- Therefore the number of moles present in Argon is 0.20 moles.
Explanation:
Mole:
The mass of a substance containing the same number of fundamental units as there are atoms in exactly 12.000 g of .
Given:
volume (v) = 4.7 litres
Volume of argon at STP conditions = 22.4 litres
To find:
volume of argon at STP conditions
We know;
n =
where;
n represents the no of moles
v represents the volume of the argon
V represents the volume of argon at STP
volume of the argon at STP conditions is 22.4 litres
So;
n =
n = 0.20 moles
Therefore the number of moles present in Argon is 0.20 moles.

Final answer:
Given 97.0 g of propane (C3H8), about 6.6 moles of CO2 will be produced according to the balanced chemical equation for the combustion of propane.
Explanation:
The question asks how many moles of CO2 will be produced from 97.0 g of C3H8, assuming O2 is available in excess.
The balanced chemical equation for the combustion of propane (C3H8) is C3H8 + 5O2 → 3CO2 + 4H2O. This tells us that one mole of propane produces three moles of CO2.
First, we need to find the moles of propane. The molar mass of propane is approximately 44.09 g/mole. So, 97.0 g of propane corresponds to approximately 2.2 moles. Therefore, 2.2 moles of propane produce 2.2 * 3 = 6.6 moles of CO2.

The ratio of atoms in HCl is
- 1:1
The ratio of atoms in hydrogen chloride shortened as HCl is 1:1. This is because there is only one atom of hydrogen that is reacted with another atom of chlorine. A ratio indicates the relative sizes of two or more quantities.
When given another compound like H₂ SO₄, we can describe the elements as being in the ratio of 2:1:4. Thus, we can see the relative quantities of the individual elements in the given compound.
In conclusion, the ratio of atoms in HCl is 1:1.

Answer:
Each molecule of HCl is composed of a one-to-one ratio of hydrogen and chlorine.
Explanation:
At room temperature, HCl is a colorless, poisonous gas. Dissolve it in water, and, voilà, you have hydrochloric acid. For the record, acids are substances that release hydrogen ions in water. The more hydrogen ions an acid releases in water, the stronger the acid (see "What is an ion?" below). If you concluded from the above discussion that HCl releases many hydrogen ions in water, you are right!

Bases have a pH of above 7, and are bitter and slippery.
Answer: c. hydroxide ions
Final answer:
Bases in a solution produce hydroxide ions (OH-). This ability to donate a hydroxide ion is what characteristically defines a substance as a base.
Explanation:
When bases dissolve in water, they produce hydroxide ions (OH-). In chemistry, bases are substances that can accept hydrogen ions (H+) or donate a hydroxide ion. For example, when sodium hydroxide (NaOH), a common base, dissolves in water, it dissociates into sodium ions (Na+) and hydroxide ions (OH-). This is the characteristic that defines a substance as a base.
