The hypothesis would be that more green bugs would be found than bright red bugs because the green bugs are more camouflaged asunder the green plants than the bright red bugs.
Answer is: <span>B) -50.2 kJ.
Balanced chemical reaction: </span>N₂(g) + 3H₂(g) → 2NH₃(g) ΔH = -<span>100.4 kJ.
This is exothermic reaction, because heat is released and energy is include as product of chemical reaction.
Make proportion, two moles of ammonia released 100.4 kJ of heat, then one mole of ammonia released:
2 mol(NH</span>₃) : (-100.4 kJ) = 1 mol : ΔH.
ΔH = -50.2 kJ; <span>heat released per mole of NH</span>₃.
The accurate answer is:
<span>[A].
Molality
The reason behind this answer is because
Molality is an ratio of the moles</span>
Answer: Option (d) is the correct answer.
Explanation:
A covalent bond is defined as the bond formed by sharing of electrons between the two chemically combining atoms.
For example, atomic number of chlorine is 17 and it has 7 valence electrons.
To attain stability it need to gain one more electron.
So, when one chlorine atom chemically combines with another chlorine atom then there occurs sharing of electrons between the two. As a result, there will be sharing of electrons.
A molecule is defined as the specie that contains same type of atoms which are chemically combined together in a fixed ratio by mass.
Noble gases tend to not bond with other elements.
