a) (NH4)2SO4 --- 1 mole of it contains 2 moles of N, 8 moles of H, 1 mole of S, and 4 moles of O.
MM = (2 moles N x 14.0 g/mole) + (8 moles H x 1.01 g/mole) + (1 mole S x 32.1 g/mole) + (4 moles O x 16.0 g/mole) = 132 g/mole.
6.60 g (NH4)2SO4 x (1 mole (NH4)2SO4 / 132 g (NH4)2SO4) = 0.0500 moles (NH4)2SO4
b) The molar mass for Ca(OH)2 = 74.0 g/mole, calculated like (NH4)2SO4 above.
4.5 kg Ca(OH)2 x (1000 g / 1 kg) x (1 mole Ca(OH)2 / 74.0 g Ca(OH)2) = 60.8 moles Ca(OH)2
When there is more thermal energy, there are less intermolecular forces. I hope this answers your question ☺️☺️
The number of moles of hydrogen atoms contained in 1 mole of c6h12 is 12.
<h3>What is hydrogen made of?</h3>
Hydrogen can be produced from various domestic resources such as fossil fuels, biomass, and the electrolysis of water by electricity. The environmental sustainability and energy efficiency of hydrogen depends on how hydrogen is produced.
Hydrogen is the simplest element. Each hydrogen atom has only one proton. Hydrogen is also the most abundant element in the universe. Stars like the Sun are mainly made of hydrogen. The sun is essentially a giant sphere of hydrogen and helium gas.
Some facts about hydrogen:
- Hydrogen is the most abundant element on earth.
- Hydrogen is an alternative fuel with a very high energy content by weight.
- The fuel cell can be used to power multiple applications.
- Fuel cells are a clean way to generate electricity.
Fuel cell vehicles are very similar to traditional gasoline vehicles

Answer:
same, different
Explanation:
Resonance structures have _same______ connectivity of atoms and __different_____ distribution of electrons.
Resonance structures are obtained in molecules where the atomic positions are the same but the electrons joining the atoms keep on delocalising. Usually, none of the resonating structures can fit the molecule or ion. This implies that the real structure is the hybrid of all the possible structures.
