Answer:
To the right
Explanation:
CH₃OH(g) + heat <=> CO(g) + 2H₂(g)
According to Le Chatelier's principle, a decrease in pressure will shift the equilibrium position to the side where there is a higher volume.
From the balanced equation above,
Volume of reactant = 1
Volume of product = 1 + 2 = 3
From the above, we can see that the volume of the gasous product is higher than the volume of the gasous reactant.
Therefore, a decrease in the pressure of the system will shift the equilibrium position to the right.
The first step to answer this question is to convert the volume of solution needed, that is in liters, to mililiters.
Use the concentration of the solution to find how many mg are present in 100mL of the solution:
Now, convert the amount of mg present in the solution to grams:
It means that 1g of NaOH is needed to prepare 0.1L of a 10mg/mL solution.
The equation to solve problem is (M1) (V1) = (M2) (V2)
M1= 10M, V1= original NaOH solution, M2= 0.5 M, V2= 2L
First, the answer needs to be in ml., so convert 2L to ml = 2000ml
(10M) (V1) = (0.5M) (2000ml)
(10M)(V1) = 1000 M/ml
V1 = 1000M/ml / 10M, the Mmoles cancel out leaving just ml.
V1 = 100ml, which is the original NaOH solution needed.
Density is the ratio of a substance's mass to its volume at a certain temperature and pressure.
Density = Mass/Volume
Since we are already given with the density and the volume, this would be easy to solve then. Just manipulate the equation to solve for mass. The equation becomes
Mass = Density*Volume
Mass = (11.35 g/cm³)(10 cm³)
<em>Mass = 11,350 g</em>
9 gram of water contains 1 g of hydrogen and 8 grams of Oxygen
- 36g of water contains 32g of oxygen
