Answer:
Volume occupied by 55.5 moles of water gas at STP = 1240 Liters.
Explanation:
1st keep in mind that 'volume' in the context of problems like this apply only to the gas phase form of the substance. Water in solid form (ice) or liquid form (liquid water) do not apply. Volume in this case is referred to as 'molar volume' and is a gas occupying 22.4 liters at STP conditions (0°C, 1Atm).
So, if 1 molar volume of water gas (steam) occupies 22.4 Liters at STP, then 55.5 moles of water gas occupies 22.4 Liters/mole x 55.5 moles = 1243.2 Liters, or 1240 Liters (3 sig. figs.). :-)

Explanation:
I just did this question in class:))
Answer:
0.7atm
Explanation:
Given parameters:
Initial temperature = 25.2°C in Kelvin; 25.2 + 273 = 298.2K
Initial pressure = 0.6atm
Final temperature = 72.4°C in kelvin = 72.4 + 273 = 345.4K
Unknown:
Final pressure = ?
Solution:
Since we are dealing with pressure temperature relationships under a fixed volume, we use a simplification of the combined gas law to solve this problem.
At fixed volume;
where P and T are temperature values
1 and 2 are the initial and final states
Input the parameters and solve for P₂
P₂ = 0.7atm

Answer:
A few elements combine to make many compounds.
Explanation:
The heading of the reading is 'Few elements, many Compounds'. The reading has focused on the process involved in the formation of elements and compounds. In the Hawaiian Islands the elements are found in abundance. These elements combine together to form compounds. The mountains, greenery, rocks and living matter are made up of many elements and compounds. The elements present helps in forming various compounds.
