Let's apply the principle of conservation of energy.
Heat of metal = Heat of water
mCmetalΔT = mCwaterΔT
Applying the given values,
(45 g)(Cmetal)(100 - 28 °C) = (130 g)(4.18 J/g-°C)(28 - 25 °C)
Solving for Cmetal,
<em>Cmetal = 0.503 J/g°C
Therefore, the heat capacity of the unknown metal is 0.503 J/g</em>°C.
B.heterogeneous mixtures
Explanation:
A heterogeneous mixture is a substance containing combination of different ingredients in different ratios.
- Heterogeneous mixtures have their constituents in different phases unlike homogeneous mixtures.
- Solutions are homogeneous of solutes and solvents that are uniformly mixed.
Heterogeneous mixtures can be subdivided into:
Gas liquid mixtures e.g aerated drinks
Liquid- solid mixtures e.g sand-sugar solution
gas solid mixtures e.g smoky air

In evolutionary theory, adaptation is the biological mechanism by which organisms adjust to new environments or to changes in their current environment.
Answer:
the second one because it has heat waves sending out
