Answer:

99.9028% consumed with 0.0972% remaining

Explanation:

A = A₀e⁻^kt

k = 0.693/t₀.₅ = (0.693/5.1)min⁻¹ = 0.136 min⁻¹

Let ...

'A₅₁' = Remaining activity at time = 51 minutes

'A₀' = 1.00

A₅₁ = 1.00e⁻⁽⁰°¹³⁶⁾⁽⁵¹⁾ = 0.000972 => 0.0972% remaining

=> 100% - 0.0972% = 99.9028% consumed

Which of the following reactions is spontaneous?
AveGali [126]
Answer is: <span>lumps os sugar dissolving in water.
Sugar has very good solubility in water and it dissolves readily, which is </span><span>example of a physical change.
</span>Gibbs free energy (G) determines if reaction will proceed spontaneously, if ΔG is negative, reaction is spontaneous <span>(ΔG = ΔH - T·ΔS).
</span>In other examples, reactions are spontaneous in reverse way, for example spontaneous is forming sodium chlorine from sodium metal and chlorine gas, but not sodium chloride forming sodium metal and chlorine gas, because a lot of energy is needed for that reaction.

A+gas+at+250k+and+15atm+has+a+molar+volume+12%+less+than+the+perfect+gas+law+character. +calculate+the+compressibility+factor
shutvik [7]

The compression factor based on the information given is 0.083.

<h3>How to calculate the compression factor?</h3>

The way to calculate the compression factor goes this:

V(ideal) = RT/P

= (0.0821 × 250)/15

= 1.368

V(real) will be:

= V(ideal)/12

= 1.368/12 = 0.114

The compression factor will be:

= 1.368/(12 × 1.368)

= 0.083

Therefore, the compression factor is 0.083.
