Answer:
Option 3. alkyne
Explanation:
The aldehydes are organic compounds with the functional group -CHO attached to parent chain it can be written as R-CHO where R is an alkyl group.
The alkenes are generally unsaturated hydrocarbon with a carbon to carbon double bond
(-C=C-) attached the parent chain.
The alkynes are unsaturated hydrocarbon with a carbon to carbon triple bond (-C≡C-) attached to the parent chain.
Alcohols are organic compounds with the functional group -OH attached to the parent chain. It can be written as R-OH where R is an alkyl group.
From the brief explanation above, the answer to the question is alkyne because the diagram has carbon to carbon triple bond (-C≡C-) attached to the parent chain.
ΔH=MCΔT
M : the mass of water (2.00x10^2)
C : water specific heat capacity (4.18 or 4.2)
ΔT : tempreture change
so energy (J) released into the water is = (200 x 4.18 x 12) = 10032J
you can convert that to KJ : 10032 / 1000 = 10.032KJ
so the energy released by 10g of octane is 10032J or 10.032KJ
hope that helps

Answer:
Magnesium and strontium
Explanation:
11 protons and 11 electrons, 12 neutrons.
The atomic number of sodium is 11, therefore the number of electrons and protons are 11. The atomic mass is 23, and to find neutrons you need to subtract the atomic number from the atomic mass, therefore the number of neutrons are 12.
