The 5 main branches of chemistry are physics, analytical, biochemistry, organic chemistry, and inorganic chemistry.
Lithium fluoride is the compound name
2 SO₃ --> 2 SO₂ + O₂
I 12 0 0
C -2x +2x +x
---------------------------------------------
E 12-2x 2x x
Since the moles of SO₂ at equilibrium is 3 mol, 2x = 3. Then, x = 1.5 mol. So, the amounts at equilibrium is:
SO₃: 12 - 2(1.5) = 9
SO₂: 2(1.5) = 3
O₂: 1.5
The formula for K basing on the stoichiometric reaction is:
K = [SO₂]²[O₂]/[SO₃]²
where the unit used is conc in mol/L.
K = [3 mol/3 L]²[1.5 mol/3 L]/[9 mol/3 L]²
<em>K = 0.0556</em>
Answer:
The term conclusion best illustrates the given statement.
Explanation:
Conclusion refers to a decision or judgment that can be acquired by reasoning. From the observation mentioned in the given table:
1. The steel, aluminum, and bronze took 27, 45 and 80 seconds to dissolve small section of wax, this signifies that more time will be needed by them to transfer heat to the food while cooking. Thus, food will take more time to cook in them.
2. Copper consumed less time, that is, 15 seconds to melt the section of wax than the other metal pots, which signifies that it is a good conductor of heat than the others. Thus, the copper pot would be good for cooking food briskly.
After evaluating the results and observations in an experiment, the conclusion was made that pots made of copper are best for cooking foods.
Answer:
6l
Explanation: convert temperature to kelvin by adding 273 and then input the values into the formula with the given constant
2*v=0.5*0.8206*288 then divide both sides by 2 and get the amount in litres which is 6
