After 11.5 days, 12.5% of a sample of radon-222 that originally weighed 42g remains. What is the half-life of this isotope?
Bond [772]
Half-life is defined as the amount of time it takes a given quantity to decrease to half of its initial value.  The equation to describe the decay is
Nt=N0(1/2) ^{t/t(1/2)}  where N0 is the initial quantity, Nt is the remaining quantity after time t, t1/2 is the half-time.  So work out the equation, t1/2 = t (-ln2)/ln(Nt/N0) = 11.5*(-ln2)/ln(12.5/100) = 3.83 days

1. Which can happen during a physical change? (2 points)
Tju [1.3M]
I believe the correct answer from the choices listed above is the first option. During a physical change, m<span>olecules can move more rapidly and freely and change states. Such action, would not disrupt or destroy the nature of the molecules they will still have  the same molecular structure. Hope this answers the question.</span>

A 975 L balloon contains helium. On the ground the temperature is 30 0C and the pressure is 743 torr. What will be the balloon's
Archy [21]

Answer:

V₂ = 1518L

Explanation:

-Using combined gas law:

\frac{P_1V_1}{T_1} =\frac{P_2V_2}{T_2}

<em>Where P is pressure, V is volume and T is absolute temperature of 1, initial state and 2, final state of the gas.</em>

<em />

<em>Initial states:</em>

P₁ = 743 torr

V₁ = 975L

T₁ = 30°C + 273.15K = 303.15K

P₂ = 375 mmHg = torr

V₂ = Our incognite

T₂ = -35°C + 273.15K = 238.15K

Replacing:

\frac{743torr*975L}{303.15K} =\frac{375torrV_2}{238.15K}

<h3>V₂ = 1518L</h3>
