The awnser is Hydrogen. It had the greatest average atomic mass
Answer:
C.
Explanation:
Stereoisomers are molecules that have the same molecular formula and with their atoms connected in the same way but pointing in different directions.
<em>cis</em>-Pent-2-ene has formula C₅H₁₀
A. is wrong, because its formula is C₅H₁₂
B. and D. are wrong, because their formulas are C₅H₈
The only option left is C. It has formula C₅H₁₀
C. is a stereoisomer of <em>cis</em>-pent-2-ene, because atoms 1 and 4 are on opposite sides of the double bond.
Think of the C=C bond as a river.
In the <em>cis </em>isomer (top), atoms 1 and 4 are on the same side of the river (zis = zame zide).
In the <em>trans</em> isomer (bottom), atoms 1 and 4 are on opposite sides of the river (trans = across or opposite).
So, C. is a stereoisomer of cis-pent-2-ene.
They have free electron(s) on their outermost energy levels making them good conductors.
They have metallic bonds in their chemical structure.
They readily lose the electrons on their outermost energy levels, to bond with non-metals in ionic bonds to form chemical compounds called "salts"
Answer:
4NH₃(g) + 5O₂(g) → 4NO(g) + 6H₂O
2NO(g) + O₂(g) → 2 NO₂
Explanation:
First of all, we need to consider the reaction for production of ammonia. In this reaction we have as reactants, nitrogen and hydroge.
3H₂ (g) + N₂(g) → 2NH₃ (g)
Afterwards, ammonia reacts to oxygen, to produce NO and H₂O
The equation for the process will be:
4NH₃(g) + 5O₂(g) → 4NO(g) + 6H₂O
Then, we take the nitric oxide to make it react, to produce NO₂, in order to produce nitric acid, for the final reaction:
2NO(g) + O₂(g) → 2 NO₂
3NO₂(g) + H₂O(g) → 2 HNO₃ (g) + NO(g)
