H2O is A chemical reaction of the most oxygen atoms
Answer:
they destroy or break stuff i think lol hope this helps
Explanation:
B.) silicon /isn't a compound it's a element
Answer:
The average number is given as 48.6
Explanation:
From the question we see that the
Percentage of cis = 47.2%
Percentage of trans = 44.9%
Percentage of vinyl = 7.9%
The chemical reaction equation for the hydrogenation of polybutadiene is shown on the first uploaded image
To obtain the average number of backbone carbon between the ethyl side chains ,we divide the total number of carbon on the backbone by the total number of ethyl group
That is
= (44.9% × 4 + 47.2% ×4 + 7.9% × 2) ÷(7.9% × 1)
= (384.2%/7.7%)
= 48.6
Note : The percentage will cancel out
At a temperature of 30 deg C, the vapour pressure of water
H2O is about 32 mm Hg. Therefore at a total pressure f 734 mm Hg, the partial
pressure of the Hydrogen gas collected is:
<span>P Hydrogen = 734 mm Hg – 32 mm Hg = 702 mm Hg</span>
