Without H2 or I2, the process starts with only HI. In this instance, equilibrium is once more attained as the concentrations of H2 and I2 grow while the concentration of HI steadily falls. Compared to H2 and I2 concentrations, HI is present at equilibrium in much larger amounts. This holds true regardless of whether the reaction started with all reactants or all products. The equilibrium position is a characteristic of the specific reversible reaction and is independent of the process through which equilibrium was reached.

<h3>What is equilibrium?</h3>

Chemical equilibrium refers to the situation in which the reactants and products are present in concentrations that are stable throughout time and do not change the system's properties in any way that can be seen. When both the forward and backward reactions are moving forward at the same speed, this condition is produced. The forward and backward reaction speeds are typically not zero, but they are equal. As a result, there are no discernible variations in the reactant and product concentrations. Dynamic equilibrium describes such a situation.

A mixture of propane and butane is burned with pure oxygen. The combustion products contain 46.7 mole% H2O. After all the water
wlad13 [49]

Answer:

28%

Explanation:

Basically, all o did was write the equations, balance it and solve for them. Also, at the place I stared, I used simultaneous equation to solve it. Multiplying by 8 and also 3.

It's a pretty straightforward question.

At the final step that's missing, I Did

A chemist has 2. 0 mol of methanol (CH3OH). The molar mass of methanol is 32. 0 g/mol. What is the mass, in grams, of the sample
natima [27]

The mass, in grams, of the sample of methanol (CH₃OH) is 64 grams.

<h3>How we calculate mass from moles?</h3>

Mass of any substance can be calculated by using moles as:

n = W/M, where

W = required mass

M = molar mass

In the question that:

Moles of methanol = 2mole

Molar mass of methanol = 32g/mole

On putting these values in the above equation, we get

W = n × M

W = 2mole × 32g/mole = 64g

Hence, 64 grams is the mass of the sample.

How many liters are in 2.75 ounces? Use the conversion factor: 1 liter = 33.814 ounces Rounded to the result to 3 significant fi
Serggg [28]
1L = 33.814 oz
xL = 2.75 oz

so it's a proportion

1L / 33.814 oz = xL / 2.75

solve for x

(1/33.814) * 2.75 = 0.0813272609 on your calculator, but it's not the answer.

the number in your problem, 2.75 oz, has 3 significant figures. so you can only round this number to 3 significant figures too.

your equipment isn't accurate enough to give a reading to 10 significant figures if that makes sense. you have to give the answer in terms of the term you use with the lowest significant figures.

so with 3 significant figures,
0.0813272609 rounds to
0.0813 L
