Answer:

Explanation:
P = Pressure = 
V = Volume = 
R = Gas constant = 
T = Temperature = 
The reaction is

From ideal gas equation we have

Moles of
produced is

Molar mass of
= 64.066 g/mol
Production rate is

The rate at which sulfur dioxide is being produced
.
I believe the first space is 1. alloys, and the second space is also 1. main. I don't know for sure but I hope this helps.
The density equals to the mass divided by volume. The equation of calculation is density= 15/3=5.0 g/ml. Notice the unit and the significant figures.
Objects have mechanical energyif they are in motion and/or if they are at some position relative to a zero potential energy position (for example, a brick held at a vertical position above the ground or zero height position). A moving car possesses mechanical energydue to its motion (kineticenergy).
