The answer is 680L because once you balance the equation, there is 2 moles of hydrogen so you multiple the amount of hydrogen by 2.
A covalent bond (I’m assuming that’s what you mean)
If the EN difference is less than 1.7, it’s a covalent bond
Answer:
The sun provides what almost everything on Earth needs to go—energy, or heat. Heat causes liquid and frozen water to evaporate into water vapor gas, which rises high in the sky to form clouds.
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
Carbon:
1s is filled. 2s is filled. 2p is shown to contain two electrons in one orbital and no electrons in the other two orbitals.
