<u>Switch the 3 and the 4</u>, this change must made to the coefficients to balance this equation.

Now, the correct balance equation is C₃H₈ + 5 O₂ → 3 CO₂ + 4H₂O

This method of balancing chemical equations involves assigning algebraic variables as stoichiometric coefficients to each species in the unbalanced chemical equation.

Convert 0.600 atm of pressure to its equivalent in millimeters of mercury. Express the pressure numerically in millimeters of me
skelet666 [1.2K]

Answer is 456 mmHg.


<em>Explanation;</em>


This is a simple unit conversion problem.


1 atm = 760 mmHg


Hence,

0.600 atm = (760 mmHg / 1 atm) x 0.600 atm

                 = 456 mmHg


Pressure can be measured by using many units such as atm, Pa, torr, bar, cmHg, mmHg and so on.


The relationships among those units as follows

1 atm = 101325 Pa = 1.01325 bar = 760 torr, 760 mmHg = 76 cmHg

If 4 moles of O2 and 8 moles of N2 occupy a 12 L
IRISSAK [1]

Answer:

P(N₂) = 4.02 atm

Explanation:

Number of moles of O₂ = 4 mol

Number of moles of N₂ = 8 mol

Total pressure = 6 atm

Partial pressure of N₂ = ?

Solution:

We will calculate the partial pressure by using mole friction.

P(N₂) = X(N₂)P(total)

X(N₂) = mol friction = moles of N₂ / total number of moles

X(N₂) = 8 mol / 12 mol = 0.67

Partial pressure of N₂:

P(N₂) = X(N₂)P(total)

P(N₂) = 0.67 × 6 atm

P(N₂) = 4.02 atm
