Answer:
What happens when it is squeezed is that its volume increases, the pressure of the material increases.
Explanation:
This is due to the fact that the elastic modulus of the sponge is high and withstands broad forces without deforming its structure, since the force is made within the proportional limit of its particles without modifying or permanently deforming them, that is why when stopping doing pressure or force on it its shape returns to being the original, this also happens due to the phenomenon of resilience
Hello!
The compound that forms from potassium and chromate is Potassium Chromate (K₂CrO₄)
This compound has a yellow lime color and is used in enamels, leather finishes, stainless steels and for the identification of silver ion in a silver nitrate solution. It is a powerful oxidizing agent and is produced by the treatment of potassium chromate with potassium hydroxide. It is a very toxic compound an is a known carcinogenic agent.
Have a good day!
Answer:
The molar mass is the mass of a given chemical element or chemical compound (g) divided by the amount of substance (mol). The molar mass of a compound can be calculated by adding the standard atomic masses (in g/mol) of the constituent atoms.
Answer:
The correct answer is "D".
Explanation:
The synthesis consists of extracting the most important data from a text or any source of information. To be able to synthesize it is necessary to read, understand and interpret the message or arguments presented. Once these factors have been extracted, they are brought together to form a coherent text that in a few words explains the original text.
Have a nice day!
Answer:
60.0mL
Explanation:
For the process of titration , the formula we use is -
M₁V₁ = M₂V₂
Where ,
M₁ = initial concentration
V₁ = initial volume
M₂ = final concentration
V₂ = final volume .
Hence , from the question ,
The given data is ,
M₁ = 0.050 M
V₁ = 30.0mL
M₂ = 0.025 M
V₂ = ?
Now, to determine the unknown quantity , the formula can be applied ,
Hence ,
M₁V₁ = M₂V₂
Putting the respective values ,
0.050 M * 30.0mL = 0.025 M * ?
solving the above equation ,
V₂ = ? = 60.0mL
