Explanation:
When ethyne undergoes a hydrogenation reaction with Ni catalyst and excess hydrogen,
C2H2 + 2H2 => C2H6.
Ethyne reacts with hydrogen gas to form ethane.
First of all, this is the chemistry section, while your question is a physics question. Anyway I'll tell you how to solve it.
First we need to find the rate that the truck moves in a second.
1km = 1000m
40km = 40000m
40000m/hr
1 hour = 60 minutes
40000m/hr ÷ 60 = 666.66(repeating)/minute
1 minute = 60 seconds
666.66m/min ÷ 60 = 11.11(rep)m/s
Next we simply multiply the speed of the truck by the number of seconds it travels.
11.11 × 5 = 55.55
Make sure to round it unless you indicate the repeating decimal.
The truck moved 55.56m in 5 seconds.
I think the correct word to fill in the blank would be carbon. Organic compounds are composed of carbon and at least one hydrogen atom. It is basically any compound that would contain carbon and covalently bonded to other elements or atoms usually these are hydrogen, nitrogen and oxygen. All living things are based on these compounds. These are the building blocks of organic chemistry. These compounds can be seen anywhere in Earth. May it be animals, plants, the soil, sugar, microorganisms and even in humans. Examples of these compounds are methanol, DNA, glucose, hexane, acetic acid, butane and the like.
Its the molecules have 20 electrons so the bear fainted.
(ANS1)— P4 + 5O2 ---> 2P2O5
(ANS2)— C3H8 + 5O2---> 3CO2 + 4H20
(ANS3)— Ca2Si + 4Cl2 ---> 2CaCl2 + SiCl4
