The lower the pH, the more acidic the solution is.
Remember, pH 7.0 is H2O. As pH decreases below 7, the solution's acidity increases. As pH increase above 7, the basicity of the solution increases.
Hence, in the choices you provided, pH 1.0 is most acidic.
pH 1 is the most acidic, as it is closest to 0 on the pH scale. Lower pH values indicate higher acidity.
Carbon has a atomic mass of 12.So its percentage is 75%
Its 5 hours. 50% of the substance is decayed at 10 hours (that is what half life means. It's full life is 20 hours). Multiple 75% times 20 hours to find that 75% is 15 hours. Subtracrt 15 hours from 20 hours to get the answer of 5 hours for the decay of 75% of the substance.
When you combine the Kw equation with the total mass of the solution, you will get a number. If the number is above 60, it is a acid, it is below 75, it is a base and if your number is between 60 and 75, it is neutral.
To calculate the velocity of a neutron with a given wavelength, you can use the de Broglie wavelength formula: λ = h / mv, where h is the Planck constant, m is the mass of the neutron, v is the velocity, and λ is the given wavelength. Solve for v to find the velocity of the neutron.
pH 1 is the most acidic, as it is closest to 0 on the pH scale. Lower pH values indicate higher acidity.

4/25 + 2/15 = 12/75 + 10/75 = 22/75
75% of 12 = 9
75% of 12= 75% * 12= 0.75 * 12= 9
12/75 = 12 ÷ 75 = 0.16
$67.510% off of $75= 10% discount applied to $75= $75 - (10% * $75)= $75 - (0.10 * $75)= $75 - $7.5= $67.5
12 over 75 in decimal form = 0.16
75 tiles would do it (a 12*12 inch time = 1 square foot) but you need 10% over this for waste so you need to get 83 tiles.
x = 16 x * .75 = 12 12 / .75 = x
75*20 = 75*(2*10) = (75*2)*10 = 150*10 = 1500
(I guess what you are trying to ask is whether 12 / 12 is bigger or 12 / 75?) 12 / 12 is bigger. Think about it in terms of, let's say... cups. If you are looking at 12 / 12, all 12 cups out of 12 are filled up so the whole thing is full. Now, if you look at 12 / 75, there are tons of cups but only a few of them are filled up and most of them are empty.
