Answer:

2 C6H14 (g) + 19 O2 (g) --> 12 CO2 (g) + 14 H2O (g)

Explanation:

For solving the stoichiometric calculations, we first need to do two steps. One of them is balancing the reaction equation. Here the balancing is done and we can see that 2 moles of hexane reacts with 19 moles of oxygen to produce 12 moles of carbon dioxide and 14 moles of water.

Now, for 2 moles of hexane, number of moles of oxygen required is 19.

So, for 7.2 moles of hexane, number of moles of oxygen required is.

= 68.4.

So 68.4 moles of oxygen is required.

Based on the law of conservation of mass, which of the following statements is correct? Matter is neither created nor destroyed.
Dmitrij [34]

The first statement (Matter is neither created nor destroyed) is correct.

The second statement would violate the law of conservation of mass (I will refer to this as LCM), as it would mean matter can "flow" into the universe, but not out, meaning the total matter will never be less than it was before.

The third statement violates LCM because it means matter is created during a reaction, which is not true.

The last statement violates LCM because it means matter is lost during a reaction, which is not true.

A 5L sample of CO2 at 540 torr and 25 degrees celsius expands to 15L at 32 degrees celsius. What is the pressure of the new cont
saw5 [17]
By  use  of  combined  gas  law
 P2=  T2P1V1/V2
v1=5L
P1=540  torr
T1=25+273=298k
V2=15 L
T2=32+273=305  k

P2  is   therefore=(  305k  x  540 torr  x5 L) /( 15L  x  298)=  184.23  torr

Dry ice, or solid cabon dioxide, has the molecular formula of CO2. How should you classify it?
Marina86 [1]
You  should classify it as  co2 solid as CO2(s) and that small left comes to the bottom right hand side and dry ice is a form of liquid carbon dioxide so u should write it as CO2(l) and that L comes to the bottom right hand sise
