If it an alkyne and gives 3-ethylhexane on hydrogenation then the reaction will be
There will be three isomers of alkyne with given molecular formula
The reactions are shown in the attached figure
To convert grams to moles, we need the molar mass of carbon. this can be founded in the periodic table.
molar mass of C= 12.0 g/mol
38.1 g C (1 mol C/ 12.0 grams)= 3.18 moles of C
Ionization Trend: First ionization energy will increase left to right across a period and increase bottom to top of a family (column).
A) Sr, Be, Mg are all in column 2 of the periodic table. Based on the first ionization rule above, from increasing to decreasing energy, the order is: Be, Mg, Sr
B) Bi, Cs, Ba are all in the same row of the periodic table. Based on the first ionization rule above, from increasing to decreasing energy, the order is: Bi, Ba, Cs
C) Same rule as above. Order is: Na, Al, S
Answer:
The answer to your question is: 28°C
Explanation:
Data
mass = 10 g
T1 = 23°C
T2 = ?
Q = 209 joules
Formula
Q = mC(T2 - T1)
T2 = Q/mC + T1
T2 = 209/(10 x 4.182) + 23
T2 = 4.99 + 23
T2 = 27.99 ≈ 28°C
