Chemical reactions are known as electron transfer reaction.
Answer:
Write a balanced chemical reaction:
N2 + 3H2 ==> 2NH3
Looking at the mole ratios in this balanced equation you can see it takes 3 moles H2 to make 2 moles NH3. So, next calculate the moles of NH3 represented by 1.80 g and then convert to moles of H2 needed:
moles of NH3 = 1.80 g x 1 mole/17 g = 0.106 moles NH3
Moles H2 needed = 0.106 moles NH3 x 3 moles H2/2 moles NH3 = 0.159 moles H2 needed
Grams H2 needed = 0.159 moles x 2 g/mole = 0.318 grams H2 needed
Explanation:
I don't think that "Maxwell's demon" is possible to happen. Take for example a boiling water poured in a glass and cold water poured in the same glass. They each have different temperatures but when they are put together in the same container, the boiling water releases its energy and absorbs some coldness of the cold water and vice versa. In the end, the water temperature will be the average temperature of both types of water. Boiling water and cold water in the same container can never keep their original temperature. It just is not possible. Even if there is a glass partition to separate these waters, heat and coldness will still be transferred between the two through the glass partition.
Answer:
Explanation:
A chemical formula is representation of a compound. Compounds are made up of two or more elements combining together.
The chemical formula of any compound is a representation which shows the elements therein and the mole relationship expressed as subscripts.
Elements in HCl - Hydrogen (H)
Chlorine (Cl)
Here 1 mole of hydrogen chloride molecule consists of 1 mole of chlorine atoms and 1 mole of hydrogen atoms.
Gas to liquid is called condensation.
Liquid to solid is called freezing/solidification.
Solid to gas is called sublimation.
Liquid to gas is called evaporating.
Solid to liquid is called melting.
Gas to solid is called deposition.
