In the unit cell of galena, six square faces of equal size each form 90 degree angles with every adjacent face. What type of cry
lbvjy [14]

Answer : The correct option is, Cubic.

Explanation :

As there are seven types of crystal systems which are cubic, tetragonal, orthorhombic, monoclinic, triclinic, rhombohedral and hexagonal.

A unit cell is characterized by the axial length (a, b and c) and axial angle (\alpha ,\beta ,\gamma ) parameters which decide the size and shape of the unit cell.

In tetragonal crystal system, a=b\neq c and \alpha=\beta=\gamma=90^o

In hexagonal crystal system, a=b\neq c and \alpha=\beta=90^o,\gamma=120^o

In triclinic crystal system, a\neq b\neq c and \alpha\neq \beta\neq \gamma=90^o

In cubic crystal system, a=b=c and \alpha=\beta=\gamma=90^o

Hence, the correct option is, Cubic.

If 3.0 liters of oxygen gas react with excess carbon monoxide at STP, how many liters of carbon dioxide can be produced under th
mr_godi [17]

Answer:

The volume of CO2 produced is 6.0 L (option D)

Explanation:

Step 1: Data given

Volume of oxygen = 3.0 L

Carbon monoxide = CO = in excess

Step 2: The balanced equation

2 CO (g) + O2 (g) → 2 CO2 (g)

Step 3: Calculate moles of O2

1 mol of gas at STP = 22.4 L

3.0 L = 0.134 moles

Step 3: Calculate moles of CO2

For 2 moles CO we need 1 mol of O2 to produce 2 moles of CO2

For 0.134 moles O2 we'll have 2*0.134 = 0.268 moles CO2

Step 4: Calculate volume of CO2

1 mol = 22.4 L

0.268 mol = 22.4 * 0.268 = 6.0 L

The volume of CO2 produced is 6.0 L
