Answer: 1.72cm
Explanation:
First let us calculate the mass of titanium that contain 2.86×10^23 atoms..
1mole of a substance contains 6.02x10^23 atoms as we have come to understand from Avogadro's hypothesis. Therefore, 1mole of titanium also contains 6.02x10^23 atoms.
1mole of titanium = 48g
1mole (i.e 48g) of titanium contains 6.02x10^23 atoms,
Therefore Xg of titanium will contain 2.86×10^23 atoms i.e
Xg of titanium = (48x2.86×10^23)/6.02x10^23 = 22.8g
Next, we must find the volume of titanium
Density of titanium = 4.5g/cm^3
Mass of titanium = 22.8g
Volume =?
Density = Mass /volume
Volume = Mass /Density
Volume = 22.8/4.5
Volume = 5.07cm^3
Now we can find the edge length:
Volume = 5.07cm^3
Length =?
V = L^3
L = cube root (V)
L = cube root (5.07)
L = 1.72cm
Answer:
The reaction in this experiment is termed an iodine clock reaction, because it is the molecular iodine (I2) that undergoes the sudden concentration change. When the iodine concentration increases, it reacts with the starch in the solution to form a complex, turning it a deep blue-black color.
Answer:
1:is option A as it have OH- group (base)
2:a),antacid as it's weak base
Answer:
chymotrypsin, cleaves peptide bonds selectively on the carboxylterminal side of the large hydrophobic amino acids such as tryptophan, tyrosine, phenylalanine, and methionine
Under certain conditions butane reacts with oxygen to form butanone which can be easily hydrogenated to butanol. Butene is easily made from butanol by elimination of water.
Explanation:
These are for the first too
