Answer:
See explanation
Explanation:
In this case, we have to remember the meaning of the nomenclature "18:2Δ9,12". Where 18 is the <u>number of carbon atom</u>s, 2 is the <u>number of double bonds,</u> and the numbers successive to Δ "delta" the position of the double bonds <u>starting</u> to count from the carboxylic -COOH end of the molecule.
In other words, the main functional group is a <u>carboxylic acid</u>. We have a total of 18 carbons. Additionally, we have 2 double bonds. On carbons 9 and 12.
Lets see figure 1
I hope it helps!
Answer:
The empirical formula is N2 CH4 O
Explanation:
Answer:
i would assume that it would be (a)
Explanation:
The Sun generates its energy by nuclear fusion
NUCLEAR FISSION is when the heavy atom is split
fusion energy is scientifically feasible. Plasma conditions that are very close to those required in a fusion reactor are now routinely reached in experiments
mass gets lost is nuclear fusion
so (a) is the most accurate
Answer : The correct option is, 
Explanation :
The given element bromine belongs to the group 17 and period 4. The symbol of bromine is, Br.
The atomic number of bromine = 35
The total number of electrons present in bromine element = 35
Electronic configuration : It is defined as the arrangement of electrons around the nucleus of an atom.
Hence, the correct electronic configuration of bromine is,
Answer:
Explanation:
Well use the combines gas law to evaluate this question;
P₁V₁/T₁ = P₂V₂/T₂ (Remember that at sea level the pressure is usually 1 atm)
1 * V₁ / 294.25 = 0.72 * V₂ / 277.95 (NB: Temperatures have to be in Kelvin)
V₁ / 294.25 * 277.95 = 0.72 V₂
0.945 V₁ = 0.72 V₂
0.945/0.72 V₁ = V₂
1.312 V₁ = V₂
The volume (V2) at 3000 m altitude will be <u>1.312 </u>bigger than the initial volume at sea level.
