Compounds that primarily contain carbon are known as organic compounds.
Answer: Mother has bb. Father has Bb.
Top left box= Bb
Top right box=bb
Bottom left box= Bb
Bottom Right box=bb
Why?
Mother has little b’s because the dominant trait would B would over power the b and give her browns eyes but she has blue so the answer is bb
Father has Bb because he has brown eyes and it says they are heterozygous meaning that he has a both the Dominant and recessive gene.
I hope this helped you :D
Answer:
Super-heavy elements like 114 usually only exist for fractions of a second. ... The physicists called these magic numbers the “island of stability”, because the elements with the numbers cluster together on the periodic table, flanked on all sides by ephemeral elements that dissipate in nanoseconds.
Answer
is: activation energy of this reaction is 212,01975 kJ/mol.<span>
Arrhenius equation: ln(k</span>₁/k₂) =
Ea/R (1/T₂ - 1/T₁).<span>
k</span>₁
= 0,000643 1/s.<span>
k</span>₂
= 0,00828 1/s.
T₁ = 622 K.
T₂ = 666 K.
R = 8,3145 J/Kmol.
<span>
1/T</span>₁ =
1/622 K = 0,0016 1/K.<span>
1/T</span>₂ =
1/666 K = 0,0015 1/K.<span>
ln(0,000643/0,00828) = Ea/8,3145 J/Kmol ·
(-0,0001 1/K).
-2,55 = Ea/8,3145 J/Kmol </span>· (-0,0001 1/K).<span>
Ea = 212019,75 J/mol = 212,01975 kJ/mol.</span>
True
Explanation:
The physical properties and the chemical reactivity of halogens are best investigated in several different compounds. Compounds of a substance gives us good knowledge about how they behave and exists in nature.
- Halogens are very reactive group of elements.
- Due to their high electronegativity, they are the most reactive on the periodic table.
- They tend to find one electron to complete their octet by all means.
- They favor reactions where they have easy access to electrons.
- When atoms combines, they have different chemical properties.
- When the molecules combine to form intermolecular bonds, it tells on their physical properties.
- The compounds of halogens is a very good way to investigate their chemical reactivity and physical properties.
