Answer:
Low density, high tensile strength. Wheelchairs and tennis racquets are better when lightweight, without detracting from their quality (strength).
Explanation:
The unknown mineral is likely "barite" due to its density of approximately 0.0251 g/cm³, which closely matches the calculated density of the unknown mineral.
To determine the unknown mineral, we can use the given information about its mass, volume of water displaced, and density. Here are the steps to find the unknown mineral:
1. Calculate the density of the unknown mineral using the formula: Density (g/cm³) = Mass (g) / Volume (cm³).
2. Use the density value to identify the mineral from the provided list.
Given:
- Mass of the unknown mineral = mass on the triple beam = 4.4 g
- Volume of water displaced = 0.175 L = 175 cm³ (since 1 L = 1000 cm³)
Now, calculate the density of the unknown mineral:
Density (g/cm³) = Mass (g) / Volume (cm³)
Density = 4.4 g / 175 cm³ = 0.0251 g/cm³
The density of the unknown mineral is approximately 0.0251 g/cm³. Now, let's find the mineral with a similar density from the provided list:
Among the given minerals, the closest density match is with "barite." Barite has a density of approximately 4.4 g/cm³, which is quite close to the calculated density of the unknown mineral.
Therefore, the unknown mineral is likely "barite."

Answer:
The amount of energy release a reaction is depended on how strong the binding energy hold the particles together
In nuclear reaction, they're breaking nucleus bind apart , which create a huge amount energy that cause by the separation of the bind. The amount is far greater than in chemical reaction which only separate the binds of electrons.
Explanation:
The volume of the NaOH that we would now need for the neutralization reaction is32.5 mL.
Neutralization is a chemical reaction in which an acid reacts with a base to form a salt and water. In this reaction, the hydrogen ions from the acid combine with the hydroxide ions from the base to form water
Number of moles of HCl = 40/1000 L * 0.65
= 0.026 moles
Since the reaction is 1:1, there would be 0.026 moles
of the NaOH used as such we would now have that;
Volume of the NaOH = 0.026 moles/0.8 M
= 32.5 mL
