Answer:
2.06 atm
Explanation:
The computation of the pressure inside the flask is shown below;
As per the ideal gas law
we know that
P V = nRT
where
V = 1.50L
T = 325 K
R = 0.0821
Now moles of N_2 is
= 3.25 ÷ 28
= 0.116 mol
Now
P = NRT ÷ V
= 0.116 × 0.0821 × 325 ÷ 1.50
= 2.06 atm
Answer:
Option A - When |ΔHsolute| > |ΔHhydration|
Explanation:
A solution is defined as a homogeneous mixture of 2 or more substances that can either be in the gas phase, liquid phase, solid phase.
The enthalpy of solution can either be positive (endothermic) or negative (exothermic).
Now, we know that enthalpy is amount of heat released or absorbed during the dissolving process at constant pressure.
Now, the first step in thus process involves breaking up of the solute. This involves breaking up all the intermolecular forces holding the solute together. This means that the solute molecules are separate from each other and the process is always endothermic because it requires energy to break interaction. Thus;
The enthalpy ΔH1 > 0.
Thus, the enthalpy of the solute has to be greater than the enthalpy of hydration.
Answer: C. There is more plate movement in California.
Explanation:
Answer:
Energy cannot be converted from one form to another.
Answer:
8800 cm / s
Explanation:
There are 100 cm / m
so: 88 m/s * 100 cm / m = 8800 cm/s
( see how the 'm' cancels out and you are left with cm /s ?)
