Answer:
<u>1092K</u>
Explanation:
We can use the combined gas law to answer this question:
P1V1/T1 = P2V2/T2,
where P, V and T are the Pressure, Volume, and Temperature for initial (1) and Final (2) conditions. Temperatures must be in Kelvin.
The problem states that V2 = 2V1 and P2 = 2P1.
Let's rearrange to solve for T2, which is the question:
T2 = T1(P2/P1)(V2/V1)
Note how the pressure and temperature values are written: as ratios. Enter the values:
T2 = (273K)(P2/P1)(V2/V1)
T2 = (273K)(2P1/P1)(2V1/V1) [Use the expressions for V2 and P2 from above]
T2 = (273K)(2)(2)
T2 = 1092K
Explanation:
An equilibrium constant of the reaction is the ratio of the concentrations of the products to the concentration of the reactants raised to their power equal to stoichiometrc coefficients in a balanced chemical equation.
Equilibrium constant equation for the reaction of acetic acid with water.
The equilibrium constant of the above reaction will written as:
Enzymes and proteins are extremely susceptible to pH changes which causes them to denature (lose the shape that gives them function). This denaturing is permanent for enzymes. A slight pH change could severely damage organ systems reducing there efficiency or completely halting their processes.
I believe it’s oxygen but I’m not sure.
Answer:
1s2 2s2 2p6 3s2 3p6 3d6
Explanation:
We are required to determine the electron configuration of Fe²⁺
We need to know that;
Atomic number of Iron (Fe) is 26
- Therefore, electron configuration of Iron (Fe) atom is [Ar] 3d64s2 or 1s2 2s2 2p6 3s2 3p6 4s2 3d6
- Fe²⁺ is a cation that is formed when a an atom of Fe loses two electrons
- Therefore;
Fe²⁺ will have 24 electrons
- Hence, the atomic configuration of Fe²⁺ is given by 1s2 2s2 2p6 3s2 3p6 3d6 since the two electrons are removed from the 4s2.
Thus, electron configuration of Fe²⁺ is 1s2 2s2 2p6 3s2 3p6 3d6
