Assuming that the gas acts like an ideal gas, we can
calculate for the final volume using the ideal gas law:
PV = nRT
Where P = pressure, V = volume, n = number of moles, R = gas
constant, and T = temperature
Assuming that P, n, and R are constant throughout the
process, we can define another constant K:
V / T = K where
K = nR / P
Equating the initial and final states:
Vi / Ti = Vf / Tf
Substituting the given values:
11.5 cm^3 / 415 K = Vf / 200 K
Vf = 5.54 cm^3
Answer:
A. ocean winds can carry moisture with them and can bring rain and fog over inland areas
Explanation:
It's "A. ocean winds can carry moisture with them and can bring rain and fog over inland areas' for K12 (OHVA to be exact)
Answer:
Enzymes may require a nonprotein cofactor or ion for catalysis to take speed up more appreciably than if the enzymes act alone;
Enzymes increase the rate of chemical reaction by lowering activation energy barriers.
Explanation:
Some enzymes need a cofactor to act, it is attached to the enzyme and can be nonprotein such as a metal ion. The enzyme function depends on the physical properties of the environmental, especially temperature and pH, each enzyme has a great point of pH and temperature where it has a maximum activity.
If the three-dimensional function of an enzyme is altered, it loses it specified and may not catalyze the reaction, because the structure of the enzyme is responsable for its specified. The catalyst occurs because the enzyme lows the activation energy barriers and this increases the rate of the reaction.
The lattice energy of the compounds is distributed in the following decreasing order of magnitude: MgO > CaO > NaF > KCl.
<h3>KCl or NaF, which has a higher lattice energy?</h3>
The lattice energy increases with increasing charge and decreasing ion size.(Refer to Coulomb's Law.)MgF2 > MgO.Following that, we can examine NaF and KCl (both of which have 1+ and 1-charges), as well as atomic radii.NaF will have a larger LE than KCl since Na is smaller then K and F was smaller than Cl.
<h3>MgO or CaO, which has a larger lattice energy?</h3>
MGO is more difficult than CaO, hence.This is because "Mg" (two-plus) ions are smaller than "Ca" (two-plus) ions in size.MgO has higher lattice energy as a result.
