What is the definition of the fugacity coefficient for a pure component, and its condition at the ideal gas state?
inn [45]

Answer:

For thermodynamics the fugacity (fi) of a non ideal gas is defined as the product between the activity (ai) of the gas and 1 bar of pressure.

Explanation:

For thermodynamics the fugacity (fi) of a non ideal gas is defined as the product between the activity (ai) of the gas and 1 bar of pressure.

f_{i} = a_{i} x 1bar

Also, in a gas mixture the fugacity (fi) of every component of the mixture is define by a coefficient of fugacity (Фi) multiplied by the partial pressure of the gas (Pi) :

f_{i} = Ф_{i} x P_{i}

The coefficient of fugacity (Фi) is a measure of the deviation from the ideality of the gas. Thus, for an ideal gas Фi = 1 and the fugacity (fi) turns equal to partial pressure:

If Фi = 1  ⇒  f_{i} =P_{i}

If you had a substance that water will not dissolve, then which of the following compounds would you choose to dissolve this sub
yanalaym [24]

Answer:

A. Vegetable oil

Explanation:

Solubility is determined by the principle , "like dissolves like" .

i.e. , if a compound is polar then it will dissolve in a polar compound only , and

if a compound is non - polar then it will dissolve in a non - polar compound only .

Hence , from the question ,

A. Vegetable oil is a non polar compound ,

B. Polar compound

C. ionic compound , is a polar compound .

Since , wate is polar in nature , hence it will get dissolved in a only polar compound ,

Therefore ,

Water will not get dissolved in vegetable oil , being it a non - polar compound .

Calculate the mass in grams of 2.56 × 10 −3 mol of iron.
gizmo_the_mogwai [7]

Answer:

1.43 grams

Explanation:

Fe = 55.8 grams Fe = 1 mole Fe

2.56 • 10^-3 moles Fe / 1 • 55.8 grams Fe / 1 mole Fe = 1.43 grams Fe

Basically, you're just multiplying the molar mass of Fe (iron) by the moles of 2.56 • 10^-3 Fe, to find how many grams are in it.

2.56 • 10^-3 moles Fe = 1.43 grams Fe

1. What is the relationship between science and society?
Rufina [12.5K]
Societies have changed over time, and consequently, so has science. For example, during the first half of the 20th century, when the world was enmeshed in war, governments made funds available for scientists to pursue research with wartime applications — and so science progressed in that direction, unlocking the mysteries of nuclear energy. At other times, market forces have led to scientific advances. For example, modern corporations looking for income through medical treatment, drug production, and agriculture, have increasingly devoted resources to biotechnology research, yielding breakthroughs in genomic sequencing and genetic engineering. And on the flipside, modern foundations funded by the financial success of individuals may invest their money in ventures that they deem to be socially responsible, encouraging research on topics like renewable energy technologies. Science is not static; it changes over time, reflecting shifts in the larger societies in which it is embedded
