see the last column in the final table of the explanation below.

Explanation:

1) Arrange the data to understand the question:

Acid                 Molarity         Moles of H⁺ released per liter

HCl                      1

H2SO4    1

H3PO4                1

H2SO4                 0.5

H3PO4                 3

HNO3                   2

2) All the given acids are strong acids, so you can consider they dissociate completely and release all the hydrogens present in the chemical formula.

3) The molarity formula is M = n/V, where n is the number of moles of solute and V is the volume of the solution in liters

From that, n = M×V

Go one by one with that formula.

Acid          Molarity    Moles of solute number of H in            Moles H⁺                                  per liter               the chemical formula per liter

HCl            1             1M×1L = 1              1                                  1×1 = 1

H₂SO4₄      1 1M×1L = 1             2                2×1 = 2
H₃PO₄        1    1M×1L = 1    3                                 3×1 = 3

H₂SO₄         0.5     0.5M×1L = 0.5   2                                2×0.5 = 1

H₃PO₄        3               3M×1L = 3            3                       3×3 = 9

HNO₃         2               2M×1L = 2            2                                 2×2 = 4

Answer from: Quest

frequency, z, and the collision density, z, in carbon dioxide (co2), r 180 pm at 30 °c and 120 kpa

Answer from: Quest

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.

Dying the folding patterns of protein molecules can microbiologists better understand cellular processes as well as some diseases, such as alzheimer’s, that are caused by proteins that have misfolded. the folding of these complicated molecules can be simulated on computers, but it takes a lot of processor power and time for even expensive supercomputers to do this. a group of researchers at stanford university developed software that can be used to distribute the processing of data to anyone who is willing to donate time on their idle personal computers. as a result, the researchers have been able to achieve protein-folding simulations that are far better than those other computing methods have done. which statement best describes the work of these researchers? the work is not scientific because the data are not processed in one location. the work is not scientific because the simulations are not reproducible. the researchers applied creativity to solve a problem in running an experiment. the researchers used only well-established scientific techniques.

Why does earth rotate? because earth is formed from cold gases collapsing due to gravity because the matter in the nebula that formed earth was spinning because earth forms more than 99% of the mass of the solar system because the hydrogen atoms inside the nebula fused to form helium
