Answer:
Explanation:
Given that,
The mass of a sample, m = 16.7 grams
Volume of the sample, V = 4.4 cm³
We need to find the density of the metal sample.
Density = mass/volume
Substituting all the values,
So, the density of the metal sample is 
.
Answer:
igneous, sedimentary, and metamorphic.
Explanation:
Igneous rocks form when molten rock (magma or lava) cools and solidifies. Sedimentary rocks originate when particles settle out of water or air, or by precipitation of minerals from water. They accumulate in layers. Metamorphic rocks result when existing rocks are changed by heat, pressure, or reactive fluids, such as hot, mineral-laden water.
Answer:
Bacteria and Plants use the process of chemosynthesis to create/make food using chemical reactions.
Explanation:
"Autotrophs that perform chemosynthesis do not use energy from the sun to produce food. Instead, they make food using energy from chemical reactions, often combining hydrogen sulfide or methane with oxygen. ... Bacteria that live in the deep ocean, near hydrothermal vents, also produce food through chemosynthesis."
Answer:
A neutral.
