compare the different pressures that result as you add air to a balloon and as you add air to a steel tank. if you answerd this
Zarrin [17]
Key to understanding scuba diving is the concept of pressure, and how it varies with depth. We intuitively understand that pressure is some type of force, but how is it actually defined? Pressure is a force or weight<span> per unit area. All matter, </span>including air<span>, has weight due to earth's gravity. Accordingly, anything exposed to air is under pressure - the weight of the atmosphere above it. This weight of air, due to gravity, is known as </span>atmospheric pressure<span> </span>

What are the coefficients of the compounds after balancing the following equation and what type of reaction is this?
Oksana_A [137]

The coefficient of Fe would be 2, the coefficient of Cl2 would be 3, while the coefficient of FeCl2 would be 2.  

The balanced equation of the reaction would be as follows:

2Fe(S) + 3Cl_2 ---> 2FeCl_3(S)

Thus, the coefficients of Fe, Cl2, and FeCl3 respectively would be 2, 3, and 2.

In other words, 2 moles of Fe require 3 moles of Cl2 to produce 2 moles of FeCl3 in a complete reaction.

A sample of oxygen gas (O2) at STP has a mass of 48.0 grams. What is the volume of the gas?
zvonat [6]
P * V = n R T 
<span>1 * 2.50 = n * 0.082 * 273 = 2. 50 / ( 0.082 * 273 ) = 0.11 mol </span>
<span>mass = mole number * molecular mass </span>
<span>mass = 0.11 * ( 16 * 2 ) = 3.52 g </span>
