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).

Answer:

1) Ice, iron, calcium oxide and mercury are pure substances since they contain particles of only one kind of matter.

2) In contrast, milk, hydrochloric acid (hydrogen chloride gas dissolved in water), brick and air cannot be called pure substances because they consists of particles of more than one kind of matter.

Some animals would be forced to migrate due to cutting of forest , Option D is the correct answer.

The complete question is

Humans clear-cut a forest. Which is one possible way that animals would most likely be affected by this action? Some animals would adapt. Some animals would go extinct. Some animals would evolve. Some animals would be forced to migrate.

Deforestation means cutting down trees of the forest for wood , or for making more space for living.

Deforestation leads to destruction of habitats of animals .

The balance of the nature gets disturbed , the sea and water bodies get dried up , leading to no water for the animals in the forest.

Animals need big bushes and trees to hide and live.

The Ecosystem gets destroyed because of the cutting of trees by human and so this has lead the animals to migrate.

Therefore Option D is the correct answer.

The molar mass of the gas with the given mass and volume at the given temperature and pressure is 16.00g/mol.

From the Ideal gas law or general gas equation;

PV = nRT

Where P is pressure, V is volume, n is the amount of substance, T is temperature and R is the ideal gas constant ( 0.08206 Latm/molK )

Given that;

First, we determine the amount of gas;

PV = nRT

n = PV / RT

n = ( 0.98026atm × 3.97L ) / ( 0.08206 Latm/molK × 294.15K )

n = 3.8916Latm / (24.137949Latm/mol)

n = 0.1612mol

Molar Mass = Mass of the gas / Amount of the gas

Molar Mass = m / n

Molar Mass = 2.58g / 0.1612mol

Molar Mass = 16.00g/mol

Therefore, the molar mass of the gas with the given mass and volume at the given temperature and pressure is 16.00g/mol.

The actual yield of the experiment given the data from the question is 92.4 g (Option B)

This is the ratio of the actual yield to the theoretical yield of a given reaction multiplied by 100

Percentage yield = (Actual / Theoretical) × 100

This is the amount obtained from the expriment procedures

This is the amount obtained from simple calculations as regarding the experiment.

Actual yield = percentage yield × theoretical yield

Actual yield = 80.34% × 115

Actual yield = 0.8034 × 115

The original volume of the gas would be 17.45 L.

For an ideal gas:

  PV = nRT, where P = pressure, V= volume, n = number of moles, T=temperature, and R = constant = 8.317 l•kpa/mol•k

In this case, n = 0.500 mole, T = 273K, P = 65.0 kpa.

Answer:

4.03 × 10²² particles of beryllium sulfide.

Explanation:

The formula to find the number of particles is:

Number of particles/atoms = number of moles × (6.02 × 10²³)

6.02 × 10²³ = Avogadro's number

But first, we will have to find the number of moles. This can be found using the formula:

Number of moles = mass ÷ Mr

  Mr of BeS = 9 + 32.1 = 41.1

  Number of moles = 2.74 ÷ 41.1 = 0.067 mol

Now that we know the number of moles, we can find the number of particles.

   Number of particles = 0.067 × 6.02 × 10²³

∴ Number of particles =  4.03 × 10²²

Answer:

4.03 × 10²² particles

In general, the formation of a chemical bond lowers the potential energy of a chemical system, leading to a more stable arrangement.

Stored energy depends upon the relative position of various parts of a system.

In bond formation, atoms lose their potential energy to attain stability and heat is evolved. The bond formation is an exothermic reaction.

Atoms bond together to form compounds to attain lower energies than they possess as individual atoms.

A quantity of energy is equal to the difference between the energies of the bonded atoms and the energies of the broken atoms.
