Answer:

Communication between scientists increased.

Technological advancements were made.

Explanation:

The options:

<em> Metalworkers began using new metals. </em>

<em>  Communication between scientists increased. </em>

<em>  The American Civil War started. </em>

<em>  Technological advancements were made.</em>

<u>The reasons the number of known elements more than double by 1861 would be because technological advancements have been made and communication between scientists increased.</u>

With the advancement in technology, more equipment become available and research became more sophisticated leading to new discoveries. The new discoveries would not have made much difference if they are not adequately communicated to other scientists.

Answer:

Coal puts out more Co2 emissions than Oil or Gas and Nuclear energy plants don't put out any pollution.

Explanation:

Even though Coal is your answer it is actually a very clean form of generating energy. Not only is it very clean but it is the most effecient means. Solar and Wind power can't even come close to the production and turnover that Coal, Gas, and Oil can. Wind Turbines are so innefficent that they somtimes don't even pay off what it took to build them in thier lifetime of service. The production of Wind Turbines puts out more pollution than any of the Coal or Natural Gas Plants. Solar power is not very efficent either but it is on it's way. It is also very expensive.

How many moles of ethylene (C2H4) can react with 12.9 liters of oxygen gas at 1.2 atmospheres and 297 Kelvin? C2H4(g) + 3O2(g) y
7nadin3 [17]
1) Convert 12.9 liters of Oxygen to mol at the given conditions:

PV = nRT ⇒ n = PV/RT

n = [1.2atm*12.9 l] / [0.082 atm l /K mol * 297K]

n = 0.636 mol of O2

2) use the stoichiometry derived from the balanced chemical equation

 1mol C2H4 / 3  mol O2 =  x mol C2H4 / 0.636 mol O2

x = 0.636 / 3 mol O2 = 0.212 mol O2.

Answer: 0.212 mol O2
