When water particles are heated to their boiling point, they begin to change form into a gas.
Because nothing appeared he concluded that <span>that living things could NOT just appear or come from nonliving things like water and air</span>
Answer:
A sugar cube is supposed to be equivalent to a teaspoon of sugar. A teaspoon of sugar is about 4.2 g. Table sugar is composed of sucrose, which is a disaccharide of glucose and fructose, with a molar mass of 342.3 g/mol. This means a sugar cube contains (4.2 / 342.3 =) 0.0123 mol of sucrose, or (0.0123 x 6.022 x 10^23 =) 7.39 x 10^21 molecules of sucrose. As one molecule of sucrose contains one molecule of glucose and one molecule of fructose, then there about 7,400 million, million, million molecules of glucose in a sugar cube.

Redox: involve the transfer of electrons between two chemical species. The compound that loses an electron is said to be oxidized, the one that gains an electron is said to be reduced. There are also specific terms that describe the specific chemical species.
Substitution:A substitution reaction is a type of chemical reaction where an atom or functional group of a molecule is replaced by another atom or functional group.
Combustion: a chemical reaction chemical that occurs between a fuel and an oxidizing agent that produces energy, usually in the form of heat and light.
So it is Redox
Hope that helped :D
Answer:
Two thirds the number of moles of hydrogen
Explanation:
The balanced reaction is
3H₂ + N₂ → 2NH₃
So 1 mol of nitrogen gas reacts completely with 3 moles of hydrogen gas, to produce 2 moles of ammonia.
If equal moles of nitrogen and hydrogen are combined, <em>then hydrogen would be the limiting reactant</em>. Let's say we have 3 moles of each reactant, one mol of N₂ reacts with the 3 moles of H₂ and produces 2 moles of NH₃, and 2 moles of N₂ would remain. So the answer is<em> two thirds the number of moles of hydrogen.</em>
