Molar mass H₂SO₄ = 98.079 g/mol
1 mol -------- 98.079 g
? mole ------ 0.0960 g
moles = 0.0960 * 1 / 98.079
= 0.0960 / 98.079
= 9.788 x 10⁻⁴ moles
hope this helps!
Explanation:
number of mole s of H
2
= 0.25 moles
number of molecules = moles * Avogadro’s Number
number of molecules = 0.25×(6.022×10
23
)
number of molecules = 1.505×10
23
single molecule of hydrogen contains two H-atoms. So,
number of atoms = 2×(1.505×10
23
) = 3.01×10

The entire sun is powered by fusion, which is a form of nuclear energy. Infrared, visible, and ultraviolet lights that are released by the sun are all forms of electromagnetic energy that the sun releases. Finally, the sun is a giant burning ball of gas, and that is the heat energy of the sun :D

Answer:
Explanation:
The difference between the two is that natural selection happens naturally, but selective breeding only occurs when humans intervene. For this reason selective breeding is sometimes called artificial selection. Different varieties of plants and animals with desired characteristics can be developed by selective breeding.
The answer is
option D "electron-cloud model." A electron-cloud model includes: includes positive charge, contains electrons, explains the photoelectric effect, suggests the probable location of electrons. It was also invented by Erwin Schrödinger.
