1 mile = 1609 m
and 1 hour = 3600 seconds
so we can convert 1220 m/s into miles per hour as following:
(1220 m/s) ×( 3600 sec/hour) ÷ (1609 m/mile)
= 2729.65 mile/hour
Answer:
(Z)-4-methyl-2-pentene
Explanation:
Hydrogenation is a syn addition. This implies that the hydrogen atoms add to the same face of the multiple bond.
Hence, if we have the alkyne, 4-methyl-2-pentyne which reacts with excess hydrogen in the presence of a platinum catalyst, we obtain (Z)-4-methyl-2-pentene since the hydrogen atoms add on the same side of the multiple bond.
Some of the particles undergo a phase change and become a gas due to burning. An example would be CO2, which is lost in the air around/escapes into the atmosphere. Hope that helps!
