Answer:
I think it may be C because Newton's second law of motion states that the acceleration of an object equals the net force acting on the object divided by the object's mass.
There's also a possibility of B as well because the Law of force and acceleration but im not sure
Answer:
The partial pressure in mm Hg for each of the species are:
PCO = 0
PH2 = 3874
PCH3OH = 347
The total pressure is 4221
Explanation:
We have to use Ideal gas equation PV = nRT and Partial pressure rule Total Pressure= ∑ Partial pressures.
We have following data:
T= 357K (85+272); nCO=0.078 (2.2/28); nH2 = 2.43 (4.86/2); R=62.36
With equation CO(g) + 2 H2(g) → CH3OH(g) we can calculate the amount of moles the reaction has finished. The limit reagent is CO because is consumed completely and moles CO in flask are 0. According to equation, every CO mol produces one CH3OH mol. That means 0.078 CO moles produces 0.078 CH3OH moles. From Ideal gas equation we have P=nRT/V.
Applying:
PH2=0.87*62.36*357/5=3874
PCH3OH =0.078*62.36*357/5=347
Total P = 3874+347=4221
I hope my answer helps you
First let us calculate the initial molarity of the 2.45 L
of solution. Molar mass = 171.34 g/mol
<span>moles Ba(OH)2 = 74.28 g * (1 mole / 171.34 g) = 0.4335 moles</span>
Molarity (M1) = 0.4335 moles / 2.45 L = 0.177 M
Now using the formula M1V1 = M2V2, we can calculate how
much to dilute (V1):
0.177 * V1 = 0.1 * 1
V1 = 0.56 L
<span>Therefore 0.56 L of the initial solution must be diluted
to 1 L to make 0.1 M</span>
Answer:
<h2>The answer is 23.63 mL</h2>
Explanation:
In order to find the new volume we use the formula for Boyle's law which is
where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume
Since we are finding the new volume
From the question
P1 = 6.3 atm
V1 = 9 mL
P2 = 2.4 atm
So we have
We have the final answer as
<h3>23.63 mL</h3>

Because oxygen is more electronegative than hydrogen, the water molecule is polar.
