19.6 × ( 1 mol KOH / 56 grams KOH )
= 0.35 mol KOH
_________________________________
0.35 mol KOH ×( 2 mol H2O / 2 mol KOH )
= 0.35 mol H20
_________________________________
0.35 mol H2O × ( 18 g H2O / 1 mol H2O )
= 6.3 grams H2O
<em>What volume do 5 moles of a gas occupy at 28 ° C and 3 atm of pressure?</em>
<em />
<h3>Further explanation</h3>
In general, the gas equation can be written
where
P = pressure, atm
V = volume, liter
n = number of moles
R = gas constant = 0.08206 L.atm / mol K
T = temperature, Kelvin
n= 5 moles
T=28 +273=301 K
P=3 atm
The volume of the gas :
The reason you are holding on to that might be because you have hope that this person who left you might come back. If they left you they aren't worth hoping for them to come back. This is a question that probably should be asked elsewhere but hope I can help.
Answer:
Explanation:
Elements that have most similar properties were placed in the same group on the periodic table and this is done based on the number of valence electron each of the element posses which allow them reach in a similar manner as a member of the same family. A group of element is placed on a a vertical column of the periodic table.
For all element with one valence electron they are labelled with 1A on the group, and are usually the first column followed by 2A until group 8.
1A element are known to be very reactive and form compounds with similar properties with other elements.
