Answer:
The answer is
<h2>0.075 kg</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
density = 762 kg/m³
We must first convert the volume from cm³ to m³
So 99 cm³ will be
So the mass of the material is
We have the final answer as
<h3>0.075 kg</h3>

Answer:
Explanation:
The reaction can be represented by this nuclear equation: 23892U → 23490Th + 42He + Energy.
Explanation:
- Combination or synthesis reaction
- Decomposition or cracking reaction
- Single replacement or single displacement
A combination or synthesis is a type of reaction that involves the formation of a single product from tow or more reactants:
K + J → KJ
The formation of a single compound form the union of their constituent element falls into this category of reaction.
The large and negative heat of formation is the driving force for this reaction.
A decomposition or cracking reaction is one in which two or more products are formed from a single reactant:
TK → T + K
The breaking down o a compound into its individual components like elements and other compounds falls into this category.
The driving force for this type of reaction is the high positive heat of formation and instability of the compound.
A single replacement or single displacement reaction is one in which a substance is replacing another.
TO + P → TP + O
The replacement of a metallic ion in solution by a metal atom higher in the activity series than the metal in a solution falls into this category of reaction.

Answer:
The half-life of Plutonium 239 (Pu 239) is 24,100 years.
Explanation:
Half-life is the time required for a quantity to reduce to half of its initial value. This means that in 241000 years, 100g of Pu 239 would be reduced to 50g.
