<span> it will add to scientific knowledge. This is because it would not become a failure, it can and will not become a law (it is not possible), and also new data would not be able to add to it because your theory was disapproved.</span>
Answer:
nitrogen, oxygen, argon, carbon dioxide, neon, helium, krypton, hydrogen, and xenon. It does not include water vapor because the amount of vapor changes based on humidity and temperature.
The unit of concentration in all the data is M. That is molarity or number of moles of solute per liter of solution.
The amount of sample or volume does not varies the concentration of the solution.
Then you only must compare the molarities and the greater the molarity (moles/liter) the greater the concentration or the more is concentrated the solution.
In this case the order is 0.90 M < 1.00 M < 1.45 M < 2.00 M.
And so, we get to the conclusion that the option C. is the most concentrated solution: 800 mL of 2.00 HCl.
Answer:
Covalent bonding occurs when electrons are shared between atoms. Double and triple covalent bonds occur when four or six electrons are shared between two atoms, and they are indicated in Lewis structures by drawing two or three lines connecting one atom to another.
Explanation:
Answer:
5.15 moles
Explanation:
2zn + o2 = 2zno
5.15 2.57 5.15 moles
nzno=500/(16x2+65)= 5.15 moles
-> nzn = 5.15 x 2 ÷ 2 = 5.15 moles
