Answer:
Single displacement reaction
Explanation:
2AI + 6HCI —> 2AlCl3 + 3H2
From the above reaction, we see clearly that Al displaces H from HCl. This is clearly a single displacement reaction.
It is believed that the entire solar system was born f<span>rom an early nebula.</span>
2 C2H6 + 7 O2 -> 4CO2 + 6 H2O
<span>so the products are carbondioxide & water vapour</span>
Answer:
The temperature is 12.35 C.
Explanation:
An ideal gas is a theoretical gas that is considered to be composed of point particles that move randomly and do not interact with each other. Gases in general are ideal when they are at high temperatures and low pressures.
An ideal gas is characterized by three state variables: absolute pressure (P), volume (V), and absolute temperature (T). The relationship between them constitutes the ideal gas law, an equation that relates the three variables if the amount of substance, number of moles n, remains constant and where R is the molar constant of the gases:
P * V = n * R * T
In this case:
- P= 2.15 atm
- V= 35.28 L
- n= 3.24 moles
- R= 0.082

- T= ?
Replacing:
2.15 atm* 35.28 L= 3.24 moles* 0.082
* T
Solving:

T=285.5 K= 12.35 C (being 273.15 K= 0 C)
<u><em>The temperature is 12.35 C.</em></u>
