P Ar = 1.5
P Xe = 0.5
P tot = 2 atm
<h3>Further explanation </h3>
Dalton's law of partial pressures states that the total pressure of a mixture of gases is equal to the sum of the partial pressures of the component gases
Can be formulated:
P tot = P1 + P2 + P3 ....
The partial pressure is the pressure of each gas in a mixture
3 L Argon , P = 1 atm and 1 L Xe, P=1 atm⇒assume T = 273 K
mol Argon :
mol Xenon :
P tot = 1.5 + 0.5 = 2 atm
In the given heating curve, Particles of the substance have the most kinetic energy when the substance is (a) 1. A gas. The part of the graph that represents where the substance has the least amount of potential energy is labeled (b) 1. Solid.
<h3>What is Heating curve ?</h3>
The heating curve is the relationship between the heating system supply temperature and the outside air temperature.
Gas molecules have the highest average velocities among the three states of matter so gas has the highest kinetic energy.
During freezing, a substance loses a lot of potential energy so solid has the least potential energy.
Hence, In the given heating curve, Particles of the substance have the most kinetic energy when the substance is (a) 1. A gas.
The part of the graph that represents where the substance has the least amount of potential energy is labeled (b) 1. Solid.

Answer:
B
Explanation:
parasites live inside the host
First, we need to find out how many moles we have of
if we are given 6.35g.
We need to calculate the molar mass of the molecule:
Cu: 63.546g
N: 14.01g * 2 = 28.02g
O: 15.999g * 6 = 95.994
Add them together to get: 187.56g
So now we need to find the number of moles we are given. This can be done by setting up a multiplication equation and cancelling the units:
So now that we know the number of moles that we have, we can use the molarity equation to find the volume of the solution. The molarity equation is:
So since we are given the molarity in the equation (0.750 M), we can plug in the molarity and moles to find the volume of the solution:
So now we know that the volume is 0.04533 Liters; however the question asks for the answer in milliliters. To do this, we must multiply by 1000:
So
the volume of the solution (<em>
in mL</em>
) is 45.33 mL.
