<h2>Hello!</h2>

The answer is:

The approximate volume is 9.84 L.

V=9.84L

<h2>Why?</h2>

Since we are given the numer of moles, the temperature and the pressure of the gas, we can calculate the approximate volume using The Ideal Gas Law.

The Ideal Gas Law is based on Boyle's Law, Gay-Lussac's Law, Charles's Law, and Avogadro's Law, and it's described by the following equation:

PV=nRT

Where,

P is the pressure of the gas.

V is the volume of the gas.

n is the number of moles of the gas.

T is the absolute temperature of the gas (Kelvin).

R is the ideal gas constant, which is equal to:

R=0.082\frac{atm.L}{mol.K}

So, we are given the information:

n=1.5mol\\Temperature=300K\\Pressure=3.75atm

Now, substituting the given information and isolating the Volume from The Ideal Gas Law equation, we have:

PV=nRT

V=\frac{nRT}{P}

3.75atm*V=1.5mol*0.082*\frac{atm.L}{mol.K}*300K

V=\frac{ 1.5mol*0.082*\frac{atm.L}{mol.K}*300K}{3.75atm}\\\\V=\frac{36.9atm.L}{3.75atm}=9.84L

So, the approximate volume is 9.84 L.

V=9.84L

Have a nice day!

Which part of the amino acid helps identify features that differentiate one amino acid from another
Natasha_Volkova [10]
The part of the amino acid which helps to identify features that differentiate one amino acid from another is the SIDE CHAIN OF EACH AMINO ACID.
Amino acids are made up of five basic parts, these are:
1. A central carbon atom
2. A hydrogen atom
3. An amino group
4. A carboxyl group and 
5. A R group, also known as a side chain.
The side chain distinguishes one amino acid from the other; different amino acids have different side chains.

Which pair of elements is most apt to form an ionic compound with each other?
sweet [91]
Ionic compounds are compounds that are formed together by a cation and an anion. A cation is an ion with a positive charge. For example, Na+ and Ca2+. An ion has a negative charge, like Cl- and OH-. There is a greater chance of forming an ionic compound when they have a great difference in electronegativity, the ability to attract electrons toward itself. In the periodic table, elements that are opposite to each other, more likely found in opposite sides, would be more apt to form an ionic compound. Example would be NaCl and CaCl2 or Ca(OH)2.

Calculate the number of grams of CO that can react with 0.400 kg of Fe2O3.
aleksandr82 [10.1K]

Answer:

mass of CO = 210.42 g

mass in three significant figures = 210. g

Explanation:

Given data:

mass of Fe2O3 = 0.400 Kg

mass of CO= ?

Solution:

chemical equation:

Fe2O3 + 3CO → 2Fe + 3CO2

Now we will calculate the molar mass of  Fe2O3 and CO.

Molar mass of  Fe2O3 = (55.845 × 2) + (16 × 3) = 159.69 g/mol

Molar mass of CO = 12+ 16 = 28 g/mol

now we will convert the kg of Fe2O3 in g.

mass of Fe2O3 = 0.400 kg × 1000 = 400 g

number of moles of Fe2O3  = 400 g/ 159.69 g/mol = 2.505 mol

mass of CO = moles of Fe2O3 × 3( molar mass of CO)

mass of CO = 2.505 mol × 84 g/mol

mass of CO = 210.42 g

mass in three significant figures = 210. g
