Hi, thank you for posting your question here at Brainly.
Typically, most spiders possess eight eyes. However, others have as many as 12, and some don't have any. These eyes are for detecting light from dark, deciphering shapes and for gathering their prey.
Answer:
Rutherford overturned Thomson's model in 1911 with his well-known gold foil experiment, in which he demonstrated that the atom has a tiny, high- mass nucleus. In his experiment, Rutherford observed that many alpha particles were deflected at small angles while others were reflected back to the alpha source.
Answer:
0.071L
Explanation:
From the question given, we obtained the following data:
Molarity of HCl = 2.25 M
Mass of HCl = 5.80g
Molar Mass of HCl = 36.45g/mol
Number of mole of HCl =?
Number of mole = Mass /Molar Mass
Number of mole of HCl = 5.8/36.45 = 0.159mole
Now, we can obtain the volume required as follows:
Molarity = mole /Volume
Volume = mole /Molarity
Volume = 0.159mole/ 2.25
Volume = 0.071L
Molarity = (numer of mole solute) / (volume of the solution)
number of mole solute = mass solute/molar mass solute
Molarity =( mass solute/molar mass solute)/ (volume of the solution)=
= ( mass solute/((molar mass solute)*(volume of the solution))
If m is a mass of the solute, M is a molar mass a solute, V is a volume of the solution (we can think as a volume of water added).
Molarity = m/(M*V)
