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

2fe + 3h2so4 -> fe2(so4)3 + 3h2

it is necessary to balance equations in order to get the proper amount of reactants as well as products in order not to make a miscalculation.

you cannot change the subscripts as that would change the substance itself. for instance, diatomic elements such as h2 only have the subscript two when a gas. another example would be so4, if you were to change the subscript, the element would no longer be sulfate.

we change the coefficients instead as that only changes the number of molecules rather than the substance itself.

hope this !

Answer from: Quest

the temperature of the gas, in k, not celsius.

Many bird species build nests in which they raise their offspring. one of these species is known as the magnolia warbler. breeding pairs of magnolia warblers build nests out of pieces of grass and twigs. the female warbler will then lay her eggs in the nest and sit on the eggs for a few weeks until they hatch. after the offspring have hatched, the female will continue to sit on the newborn chicks to keep them warm. both the male and the female bring food for the offspring to eat until the young are mature enough to find food on their own. which of these most likely describes why birds such as the magnolia warbler build nests in which to raise their offspring? a. nest building decreases the amount of energy used by the parent birds to raise their offspring to adulthood. b. nest building increases the probability that the offspring will survive and eventually produce offspring of their own. c. nest building decreases the amount of food that the offspring require the adult birds to provide. d. nest building increases the probability of the offspring being located by airborne predators.
