Answer:
There is 3 because K2 is its own atom and it has 2 K2 and Co3 is its own and there's one

This is what I was taught
Answer:
Oxygen Depletion
Explanation:
In addition to the eutrophication of water bodies, wastewater effluents also contribute to another process of deoxygenation. The biological (bacterial) breakdown of organic solids in the effluent also consumes dissolved oxygen – the biological oxygen demand (BOD). In addition, the degradation of chemicals in the effluent removes oxygen from the water through chemical reactions – the chemical oxygen demand (COD).
As was previously mentioned, the loss of dissolved oxygen in the water can result in serious immediate, short-term, or long-term consequences to aquatic life. Fish survival is particularly affected by low oxygen levels. Decreased disease resistance, reduced growth, altered swimming behaviour, feeding, migration, and reproduction, increased threat of predation, and even rapid death are some of the effects of low dissolved oxygen concentrations.
Low oxygen levels can also alter the kinds of species present in the ecosystem. With a change in food supply, some populations of species decrease, while others increase. Fish such as whitefish, walleye, and pike may disappear, while bottom-feeding fish such as carp may increase in number.
Answer: Metamorphic rocks will be exposed to weathering and can break down into sediment and then be compressed to form sedimentary rocks.
Explanation:
D. weathered remains of other rocks
Explanation:
The raw material from which sedimentary rocks are formed are from the weathered remain of other rocks.
Sedimentary rocks are rocks that are derived from the deposition of rock fragments and precipitations in basins.
- Most sedimentary rocks are clastics. They are products of rock fragments that have been weathered.
- Some are chemical rocks that forms from the precipitation of minerals from solutions.
- Weathering is the physical disintegration and chemical decomposition of rocks to form sediments.
- The sediments are used to produce sedimentary rocks when carried away and deposited in basins.
