Answer:
The new pressure is 1,52 atm
Explanation:
We use the gas formula, which results from the combination of the Boyle, Charles and Gay-Lussac laws. According to which at a constant mass, temperature, pressure and volume vary, keeping constant PV / T. We convert the unit Celsius into Kelvin:
75°C=273+75=348K ; 103°C=273+103=376K
(P1xV1)/T1=(P2xV2)/T2
(1,65atm x4,54L)/348K= (P2x 5,33L)/376K
0,0215 atmxL/K=(P2x 5,33L)/376K
P2=(0,0215 atmxL/K x 376K)/5,33l= 1,52 atm
Answer: 2ML
Explanation: all you needed to do was to subtract
Answer:
D) Mn + Ni2+ ⇒ Mn2+ + Ni
Explanation:
A spontaneous process is capable of proceeding in a given direction without needing to be driven by an outside source of energy. A Spontaneous reaction takes place on its own without external influences. In a spontaneous reaction, this change in entropy is positive (ΔS) , the change in enthalpy is negative (ΔH) and most importantly the
value of ΔG(change is free energy) is negative.
In order to decide the spontaneous reaction among the options, we consider the relative electrode potentials of the reaction species. The specie having a more negative reduction potential can displace the other specie from its aqueous solution. Since the reduction potential of Mn^2+ is -1.19 V while that of nickel is -0.25 V, it follows that manganese can spontaneously displace Ni^2+ from its aqueous solution as shown in the answer above.

Explanation:
Hello,
Here, by using the Dalton's law, we can quantify the total pressure of a gaseous mixture by knowing the partial pressure of each gas, in case, hydrogen, helium and argon:
In such a way, since we actually know the partial pressure of helium and argon, and the total pressure, we can compute the partial pressure of hydrogen as shown below:
Best regards.
Answer:
Temperature and volume are directly related.
The volume of a given gas sample is directly proportional to its absolute temperature at constant pressure. :)
