Answer:
<h2>252.9 kPa</h2>
Explanation:
The new pressure can be found by using the formula
where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume
From the question we have
We have the final answer as
<h3>252.9 kPa</h3>
Hope this helps you
D.
The water must be heated and removed in distillation, so thermal energy is required.
Answer:
3 significant zeroes
Explanation:
To count the number of significant figures, you must pass the zeroes until you reach a non-zero value. Once you reach it, count anything after that as significant values, including the non-zero value itself.
The number has 4 significant figures with 3 significant zeroes.
Hope this helps!!!
From all the calculations that were carried out, the concentration of 2atm is 0.0026 M.
<h3>What is molarity?</h3>
The term molarity is defined as the number of moles divided by the volume of the solution. Using the formula; C = kp where
- C = concentration
- k = constant
- p = pressure
C = 0. 0354 * 10^-3 g/28 g/mol × 1000/1 L
C = 0.0013 M
k = C/p = 0.0013 M/1 atm
k = 0.0013 Matm-1
Now;
C = 0.0013 Matm-1 * 2 atm
C= 0.0026 M

The enthalpy change for the reaction 2K + S + K2S using the following thermochemical reactions is mathematically given as
dn=70.7kg
<h3>What is the enthalpy change for the reaction?</h3>
Generally, the equation for the Chemical reaction is mathematically given as
2k+s----->K2S
Therefore
KS+K----->K2S
Therefore
dn=dn1+dn2
dn=32.5+38.2
dn=70.7kg
In conclusion, the enthalpy change is
dn=70.7kg
