Answer:

238 94Pu

Explanation:

From the question given, we noticed that the element is undergoing beta minus decay. This means that the daughter nuclei obtained will have the same mass number as the parent element and the the atomic number of the daughter nuclei will increase by 1.

Please see attached photo on how to arrive at the answer.

The value of the equilibrium constant for a reaction is 2.65 x 10-6 at 35° Calculate the value of LaTeX: \DeltaΔG°rxn.

stealth61 [152]

Answer:

The answer is "33.95 $\bold{ \frac{kj}{mol}}\\$ ".

Explanation:

Formula:

$\bigtriangleup G_0= -R \times T l_n \times K_{eq}\\$

where

$K_{eq} = \text{equilibrium constant}\\$

Given value:

$T =35^{\circ} C\\$

convert temperature celsius (°C) to Kelvin (K):

$= (273+45) \ kelvin \\\\= 318 \ Kelvin \\\\= 318 \ K$

$R = 8.314 \ \ \frac{J}{ mol \cdot K}$

$\bigtriangleup G_0= -(8.314 ) \times 31.8 \times l_n (2.65\times 10^{-6})\\$

$=-(8.314 ) \times 31.8T l_n \times (2.65\times 10^{-6})\\\\$

After solving the value it will give:

= 33.95 $\bold{ \frac{kj}{mol}}\\$

Calculate the volume occupied by 55.5 moles of water at STP.

Tems11 [23]

Answer:

Volume occupied by 55.5 moles of water gas at STP = 1240 Liters.

Explanation:

1st keep in mind that 'volume' in the context of problems like this apply only to the gas phase form of the substance. Water in solid form (ice) or liquid form (liquid water) do not apply. Volume in this case is referred to as 'molar volume' and is a gas occupying 22.4 liters at STP conditions (0°C, 1Atm).

So, if 1 molar volume of water gas (steam) occupies 22.4 Liters at STP, then 55.5 moles of water gas occupies 22.4 Liters/mole x 55.5 moles = 1243.2 Liters, or 1240 Liters (3 sig. figs.). :-)
