To simplify our solution for this probelm we first assume that the gas we are dealing with is an ideal gas. Given that it is ideal we can proceed the solution using the formula: PV=nRT where P is pressure (203KPa), V is volume (20.0 L), n is moles (required), T is absolute temperature (373K) and R is the gas constant ( <span>8.31 l-kpa/m-k). Plug in the given to the respective variables and you should get 3.28 moles of the gas sample. </span>

The standard cell potential, E°cell, for a reaction in which two electrons are transferred between the reactants is +1.33 V. Cal
Alinara [238K]

Answer:

ΔG° = 2.57 × 10² kJ

The reaction is spontaneous.

Explanation:

<em>The standard cell potential, E°cell, for a reaction in which two electrons are transferred between the reactants is +1.33 V. Calculate the standard free energy change, ΔG°, in kJ for this reaction and determine if it is spontaneous or nonspontaneous at 25°C.</em>

<em />

We can calculate the standard Gibbs free energy (ΔG°) using the following expression.

ΔG° = -n × F × E°cell

where,

n: moles of electrons transferred

F: Faraday's constant

E°cell: standard cell potential

ΔG° = - (2 mol) × (96468 J/V . mol) × 1.33 V

ΔG° = -2.57 × 10⁵ J = 2.57 × 10² kJ

ΔG° < 0 means that the reaction is spontaneous.

How many grams of carbon dioxide are in 88.5 L at STP?
34kurt

Answer:

173.8g

Explanation:

STP means standard temperature and pressure

The temperature there is 273k while the pressure is 1 atm

now we are to use the ideal gas equation to get the number of moles first

Mathematically;

PV = nRT

here P = 1 atm

V = 88.5 L

n = ?

R = molar gas constant = 0.082 L atm mol^-1 K^-1

Now rewriting the equation we can have

n = PV/RT

plugging the values we have

n = (1 * 88.5)/(0.082 * 273)

n = 88.5/22.386

n = 3.95 moles

Now we proceed to get the mass

Mathematically;

mass = no of moles * molar mass

molar mass of carbon iv oxide is 44g/mol

mass = 3.95 * 44 = 173.8 g

!! ANSWER QUICK !!
kari74 [83]

Answer:

I can use a dichotomous key. It helps me classify objects by sorting it out with "yes" and "no" questions.

or

I can use a Punnett Square. It helps me classify what genes the offspring will receive simply by figuring out the recessive and dominant genes as well as the hetzygous and homzygous.

Now give an example of which ever chart you choose by drawing it if that is required. For the Punnett Square label each of the squares Top right Hetzygous, top left dominant, bottom left recessive, bot-tom right homzygous. And for the dichotomous key put a 5-7 length branch showing the animals that have fur, can breathe under water, what cannot or doesn't have those traits. or something similar

Hopefully this helps :)
