The four metals that will not replace hydrogen in an acid are Cu, Ag, Au, Hg.
Explanation:
- As Copper Cu lies below the hydrogen, this is why it is less reactive and ca not replace Hydrogen from its compound.
- Silver Ag also lies below the hydrogen and therefore it is less reactive to displace Hydrogen.
- Gold Au becomes less reactive than Hydrogen due to its placement below Hydrogen acid.
- Mercury Hg is less reactive than Hydrogen
<h3>
Answer:</h3>
1 Nitrogen atom and 3 Hydrogen atoms
<h3>
Explanation:</h3>
- A molecule is the smallest particle of an element or a compound that has the properties of the element or the compound.
- Molecules of elements are made up of similar atoms while those of compounds are made up of different atoms from different elements.
- Compounds are made up of atoms of different elements.
- For example, NH₃ is made up of one nitrogen atom and three ammonia atoms, water(H₂O) is made up of two hydrogen atoms and one oxygen atom.
8m of hydrogen will react with 1 mol of sulfur.
Answer:
1=4
2=2
3=hydrogen bonding
4=SO2 is reduced to Sulphur

Answer:
Extensive properties, such as mass and volume, depend on the amount of matter being measured. Intensive properties, such as density and color, do not depend on the amount of the substance present.
