Answer:
The volume occupied by 2.18 moles of is 48.832L
Explanation:
The volume occupied by 1 mole of is 22.4 L
The volume occupied by 1 mole of any gas is 22.4 L
The number of moles of = 2.18 moles
The volume occupied by 2.18 moles of :
Hence, the volume occupied by 2.18 moles of is 48.832L
Answer is: B.) Yes, if work is done, this transfer process can take place.
For example, air conditioner involves a cyclic process that transfers heat from a cold reservoir to a hot reservoir, but with use of electricity.
Thermal conductuction is the transfer of heat through physical contact. Thermal conduction is the transfer of heat by microscopic collisions of particles. Heat spontaneously flows from a hotter to a colder body.
The process of heat conduction depends on four basic factors: the temperature gradient, the cross section of the materials involved, their path length and the properties of those materials.
It would take 1.16 h for the runner to finish the race
.
<em>Step 1. </em>Convert <em>kilometres to miles</em>.
11 km × (0.621 mi/1 km) = 6.83 mi
<em>Step 2</em>. Calculate the <em>time</em>.
Time = 6.83 mi × (1 h/5.7 mi) = 1.16 h
The strong base will be dissociated completely into the aqueous solution. The pOH of the solution can be determined by the concentration of the hydroxide ion. The strong bases have lower pOH value.
