Somebody please help meeeeeeeeee!! (The question is underneath the table)

Chemistry
1 answer:
Annette [7]2 years ago
6 0

Answer:

1.)

Parent 1:
   Ff (genotype) and free earlobes (phenotype)

Parent 2:
   ff (genotype) and attached earlobes (phenotype)

2.)

Ff and ff (possible genotypes)

Free earlobes and attached earlobes (possible phenotypes)

Explanation:

Phenotypes are the observable traits an organism displays.

Genotypes are the genetic sequences organisms' possess that code for particular traits.

I am assuming that heterozygous individuals (Ff) display the dominant trait (free earlobes). As such, one parent has the Ff genotype and the free earlobe phenotype. The other parent has the recessive genotype (ff) and phenotype (attached earlobe).

50% of the children will have the same genotype and phenotype of one parent and the other 50% will have the same genotype and phenotype as the other parent.

None of the children will have the completely dominant genotype (FF).

Alchemists were medieval scholars and philosophers who were the forerunners of modern-day chemists. many tried repeatedly to tra
AlladinOne [14]

Answer is: because they were using simple chemical reactions to transform elements, but that is possible only with nuclear reactions, which in that time were not possible to conduct.

Nuclear reactions can produce new elements, because number of protons and neutrons is changed, lead and gold have different atomic and mass numbers.

The electrons of an atom participates in a chemical reaction, chemical reactions involve the rearrangement of electrons, because there is transfer, loss, gain and sharing of electrons in chemical reactions, new elements are not formed.

______ will have a higher entropy than 50.0 g CO2 (g) at 56 oC.
Tomtit [17]
1) The more mass is the more entropy , because there are more particles, there is disorder.
2) Than higher temperature --- the more entropy.
3) Gas has more disorder than liquid, so gas has more entropy.
So, correct answer is E.

How many molecules of copper sulfate are needed to produce 5.0×1024 molecules of sodium sulfate?
lubasha [3.4K]

Answer:

5.0 × 10²⁴ molecules

Explanation:

Step 1: Write the balanced double displacement reaction

2 NaOH + CuSO₄ ⇒ Na₂SO₄ + Cu(OH)₂

Step 2: Calculate the moles corresponding to 5.0 × 10²⁴ molecules of Na₂SO₄

We will use Avogadro's number: there are 6.02 × 10²³ molecules in 1 mole of molecules.

5.0 × 10²⁴ molecule × 1 mol/6.02 × 10²³ molecule = 8.3 mol

Step 3: Calculate the moles of CuSO₄ required to produce 8.3 moles of Na₂SO₄

The molar ratio of CuSO₄ to Na₂SO₄ is 1:1. The moles of CuSO₄ required are 1/1 × 8.3 mol = 8.3 mol.

Step 4: Calculate the molecules corresponding to 8.3 moles of CuSO₄

We will use Avogadro's number.

8.3 mol × 6.02 × 10²³ molecule/1 mol = 5.0 × 10²⁴ molecule

What kind of a bond is oc2
nexus9112 [7]

Answer:

A carbon–oxygen bond is a polar convalescent bond between carbon and oxygen. Oxygen has 6 valence electrons and prefers to either share two electrons in bonding with carbon, leaving the 4 nonbinding electrons in 2 lone pairs :O: or to share two pairs of electrons to form the carbon functional group.
