1st fission event

n + fission reactant -> fission product + n + n

so the 2 n created can initiate 2 new reactions


2nd fission event, for each n

n + fission reactant -> fission product + n

so the 1 n created can initiated 1 new reaction


In 1st event 2n are created.

In 2nd event, the 2n from 1st created 1n each for a total of 2n.

combining both events, 2n + 2n = 4n are produced in total.

g Green plants use light from the Sun to drive photosynthesis. Photosynthesis is a chemical reaction in which water and carbon d
LenaWriter [7]

Answer:

6.49g

Explanation:

Let's consider the balanced reaction for photosynthesis.

6 CO₂ + 6 H₂O = C₆H₁₂O₆ + 6 O₂

We can establish the following relations:

  • 1 mole of CO₂ has a mass of 44.01 g (MW 44.01)
  • The molar ratio of CO₂ to C₆H₁₂O₆ is 6:1.
  • 1 mole of C₆H₁₂O₆ has a mass of 180.16 g/mol.

The mass of glucose produced by the reaction of 9.51 g of carbon dioxide is:

9.51gCO_2 \times \frac{1molCO_2}{44.01gCO_2}  \times \frac{1molGlucose}{6molCO_2}  \times \frac{180.16gGlucose}{1molGlucose} = 6.49g Glucose

The edge of the card measures 2.5 inches, what is it in cm?
Citrus2011 [14]

Answer:

6.35 centimeters

Explanation:

<em>2.5 inches</em> = <em>6.35 centimeters</em>

Formula:

  • <em>multiply </em><em>the value in </em><em>inche</em><em>s by the </em><em>conversion</em><em> factor '</em><em>2.54'.</em>

So, 2.5 inches = 2.5 × 2.54 = 6.35 centimeters.

Radioactive cobalt-60 is frequently used in treating cancer. It took 24 years for a 10 gram sample to decay to 0.625 grams. What
-BARSIC- [3]

Answer:

Half life is 6 years.

Explanation:

T½ = In2 / λ

Where λ = decay constant.

But N = No * e^-λt

Where N = final mass after a certain period of time

No = initial mass

T = time

N = 0.625g

No = 10g

t = 24 years

N = No* e^-λt

N / No = e^-λt

λ = -( 1 / t) In N / No (inverse of e is In. Check logarithmic rules)

λ = -(1 / 24) * In (0.625/10)

λ = -0.04167 * In(0.0625)

λ = -0.04167 * (-2.77)

λ = 0.1154

T½ = In2 / λ

T½ = 0.693 / 0.1154

T½ = 6.00 years.

The half life of radioactive cobalt-60 is 6 years
