Answer:
6,613 M
Explanation:
Dilution is the process of reducing the concentration of a solute in solution, mixing initial solution with more solvent.
The concentration of Solution B is:
23,881 M × = 9,552 M
Because the initial eight parts are diluted to 12+8 parts.
Thus, concentration of solution C is:
9,552 M × = 6,613 M

The balanced chemical equation for the reaction is
2Ca(s) + O₂(g) → 2CaO(s)
and
The process meets the requirements to be considered a redox reaction.
From the question,
We are to write a balanced chemical equation for the reaction between Calcium metal and oxygen gas
The balanced chemical equation for the reaction is
2Ca(s) + O₂(g) → 2CaO(s)
This is the balanced chemical equation for the reaction
To determine whether the reaction meets the requirements to be considered a redox reaction,
We will define the term <em>redox reaction</em>
<em></em>
A <em>redox reaction</em>, also called oxidation-reduction reaction, is any chemical reaction in which the oxidation number of a participating chemical species changes.
From the balanced equation above we can observe that the oxidation number of the participating species(Calcium and oxygen) changed.
The oxidation number of Calcium changed from 0 to +2
and
The oxidation number of Oxygen changed from 0 to -2
∴ The process meets the requirements to be considered a redox reaction.
Hence, the balanced chemical equation for the reaction is
2Ca(s) + O₂(g) → 2CaO(s)
and
The process meets the requirements to be considered a redox reaction.

Alloy: alloy, metallic substance composed of two or more elements, as either a compound or a solution. The components of alloys are ordinarily themselves metals, though carbon, a nonmetal, is an essential constituent of steel. ... See also amalgam; ferroalloy; intermetallic compound
Ceramic: A ceramic is any of the various hard, brittle, heat-resistant and corrosion-resistant materials made by shaping and then firing an inorganic, nonmetallic material, such as clay, at a high temperature. Common examples are earthenware, porcelain, and brick.
Synthetic polymer: Synthetic polymers are derived from petroleum oil, and made by scientists and engineers. Examples of synthetic polymers include nylon, polyethylene, polyester, Teflon, and epoxy. ... Vulcanized rubber is a synthetic (man-made) polymer, while pectin is an example of a natural polymer

Answer:
The pressure exerted by the buggy on the surface of Mars is 1600 pascals.
Explanation:
The pressure is determined by the definition of stress, which is the force exerted by the buggy on the martian surface divided by the contact area of the latter:
Where:
- Stress, measured in pascals.
- Force, measured in newtons.
- Area, measured in square meters.
The force is the weight of the buggy (40 N) and 
, the stress is now calculated:
The pressure exerted by the buggy on the surface of Mars is 1600 pascals.
