6. What is the pressure of 0.60 moles of a gas if its volume is 10.0 liters at 35.0°C?

denis-greek [22]

Answer: The pressure inside the cylinder will be 1.5 atm. The pressure can be calculated using the Ideal Gas Equation which relates the pressure, volume, temperature, and amount of gas to each other.

Further Explanation

The Ideal Gas Equation is:

$PV = nRT$

where:

P - pressure (in atm)

V - volume (in L)

n - amount of gas (in moles)

R - universal gas constant $0.08206 \frac{L-atm}{mol-K}$

T - temperature (in K)

In the problem, we are given the values:

P = ?

V = 10.0 L (3 significant figures)

n = 0.60 moles ( 2 significant figures)

T = 35.0 degrees Celsius (3 significant figures)

We need to convert the temperature to Kelvin before we can use the Ideal Gas Equation. The formula to convert from degree Celsius to Kelvin is:

$Temperature \ in \ Kelvin = Temperature\ in \ Celsius \ + \ 273.15$

Therefore, for this problem,

$Temperature\ in \ K = 35.0 +273.15\\Temperature\ in \ K = 308.15$

Solving for P using the Ideal Gas Equation:

$P = \frac{nRT}{V} \\P = \frac{(0.60\ mol) \ (0.08206 \ \frac{L-atm}{mol - K}) \ (308.15\ K) \ }{10.0 \ L} \\P = 1.51\ atm$

The least number of significant figures is 2, therefore, the final answer must have only 2 significant figures.

The two reactants combine to form a single product, ammonia, nh3, which is not shown. write a balanced chemical equation for the

nikdorinn [45]

If the product is ammonia, the reactants must be the diatomic gases N₂ and H₂. The complete balanced reaction is shown below:

N₂ + 3 H₂ → 2 NH₃

Now, the number of molecules on the left or reactant side are: 2 molecules of nitrogen and 3*3 = 6 molecules of hydrogen. The total number would be 8 molecules. The same number of molecules is counted on the right or product side. This is to obey the Law of Conservation of Mass.

Which element will only gain one electron during a chemical reaction?

Gelneren [198K]

Halogens

Explanation:

Halogens are a group of non-metals located in the seventh group on the periodic table. The will only gain one electron during a chemical reaction.

Halogens have a seven electrons in their outermost shell.
To complete the number of electrons in this shell, they need to gain an additional electron.
One more electron makes the halogen similar to the corresponding noble gas which is very stable.
Halogens are very reactive groups of elements and are highly electronegative.
They have a high affinity for electrons.
These elements are fluorine, chlorine, bromine, iodine and Astatine.
