Natural selection was proposed by Charles Darwin to explain how new species evolve. All types of living things have small differences between the individuals in the species. If one of those differences allows the individual to live longer, they will likely have more offspring. As that trait is passed on, the population starts to look more like the successful individual. Over time, the species changes.


In 1896, J. W. Tutt suggested that the peppered moths were an example of natural selection. He recognized that the camouflage of the light moth no longer worked in the dark forest. Dark moths live longer in a dark forest, so they had more time to breed.


1. What is natural selection?


2. How are peppered moths an example of natural selection?



FOLLOW THE INSTRUCTIONS PLZZZ

Answers

1.Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations. 

2.Because predators were able to spot the light moths more easily, the dark moths were more likely to survive and reproduce. ... The peppered moth case is an example of natural selection. In this case, changes in the environment caused changes in the characteristics that were most beneficial for survival

What mass of sodium phosphide would be needed to react fully with 5.4x1025 formula units of
strontium oxide?

Answers

Answer:

5974 g of Na₃P

Explanation:

We determine the reaction:

2Na₃P + 3SrO  →  3Na₂O + Sr₃P₂

2 moles of sodium phosphide react to 3 moles of strontium oxide to produce 3 moles of sodium oxide and 1 mol of strontium phosphide.

We know that 1 mol of anything contains 6.02×10²³ formula units, so:

5.4×10²⁵ formula units . 1 mol/6.02×10²³ formula units = 89.7 moles

This is the amount we have, initially for SrO.

Ratio is 3:2. 3 moles of SrO react to 2 Na₃P

Then 89.7 moles of SrO may react to (89.7 . 2) /3 = 59.8 moles of Na₃P

We convert the moles to mass (mass . molecular weight)

59.8 mol . 99.9 g /mol = 5974 g

An atom of a certain element has 19 protons, 19 electrons, and a mass number of 39. This element is very reactive. How many neutrons are in this atom?

Answers

Answer:

There would be [tex]20[/tex] neutrons in that atom.

Explanation:

The mass number of an atom is the sum of:

the number of neutrons in this atom, andthe number of protons in this atom.

Electrons do not contribute to the mass number of an atom.

From the question:

Mass number of this atom: [tex]39[/tex].Number of protons in this atom: [tex]19[/tex].

[tex](\text{Mass Number}) = (\text{Number of protons}) + (\text{Number of neutrons})[/tex].

In this atom:

[tex]39 = 19 + (\text{Number of neutrons})[/tex].

Hence, the number of neutrons would be [tex]39 - 19 = 20[/tex].

How is the chemical bonding between atoms of magnesium different from the chemical bonding within a crystal of aluminum iodide?

Answers

Answer:

See explanation

Explanation:

The bond between magnesium atoms is a metallic bond while the bond within a crystal of aluminum iodide is an ionic bond.

A metallic crystal consists of a sea of electrons that are electrostatically attracted to positive metal ions. This is the nature of the bonding between magnesium atoms in a crystal of magnesium.

In aluminum iodide, there is a transfer of electrons from aluminium to iodine which is typical of an ionic bond. Electrostatic interaction holds oppositely charged ions together in the crystal of aluminum iodide.

Atomic mass of Sulfur = 32g

32g of Sulfur is one mole.

1g of Sulfur is [tex] \frac{1}{32} moles [/tex]

96.21g of Sulfur is [tex] \frac{96.21}{32} moles=> 3moles(appx) [/tex]

Answer:

[tex]\boxed {\boxed {\sf 3 \ moles \ sulfur}}[/tex]

Explanation:

To convert from grams to moles, the molar mass is used. This value is the number of grams in 1 mole of a substance and it can be found on the Periodic Table. Look for Sulfur or S.

Sulfur: 32.07 g/mol

We use this as a ratio.

[tex]\frac {32.07 \ g \ S}{1 \ mo;\l\ S }[/tex]

Multiply by the given number of grams.

[tex]96.21 \ g \ S*\frac {32.07 \ g \ S}{1 \ mo\l\ S }[/tex]

Flip the fraction so the grams of sulfur cancel out.

[tex]96.21 \ g \ S*\frac {1 \ mol \ S}{32.07 \ g \ S }[/tex]

[tex]96.21*\frac {1 \ mol \ S}{32.07 }[/tex]

[tex]\frac {96.21 \ mol \ S}{32.07 }= 3 \ mol \ S[/tex]

96.21 grams of sulfur is equal to 3 moles of sulfur.

10.00 g of O2 reacts with 20.00 g NO Determine the amount of NO2, limiting reactant, and the excess reactant.

Answers

Answer:

Limiting reactant: O₂

Excess reactant: NO

Amount of NO₂ produced: 28.75 g

Explanation:

The balanced equation for the reaction between O₂ and NO to produce NO₂ is the following:

O₂(g) + 2NO(g) → 2NO₂(g)

According to the equation, 1 mol of O₂ reacts with 2 moles of NO to produce 2 moles of NO₂.

We first convert the moles of each compound to mass by using the molecular weight (MW):

MW(O₂) = 16 g/mol x 2 = 32 g/mol

⇒ mass O₂ = 1 mol O₂ x 32 g/mol O₂ = 32 g

MW(NO) = 14 g/mol + 16 g/mol = 30 g/mol

⇒ mass NO = 2 mol NO x 30 g/mol NO = 60 g

MW(NO₂) = 14 g/mol + (2x 16 g/mol) = 46 g/mol

⇒ mass NO = 2 mol NO₂ x 46 g/mol NO₂ = 92 g

For the reactants, the stoichiometric ratio is 32 g O₂/60 g NO. Thus, the mass of O₂ required to completely react with 20.00 g of NO is:

mass of O₂ required = 20.00 g NO x 32 g O₂/60 g NO = 10.67 g O₂

We need 10.67 g of O₂ and we have only 10.00 g, so the limiting reactant is O₂. Thus, the excess reactant is NO.

With the limiting reactant, we calculate the amount of product produced (NO₂). For this, we consider the stoichiometric ratio 92 g NO₂/32 g O₂:

mass of NO₂ produced = 10.00 g O₂ x 92 g NO₂/32 g O₂ = 28.75 g NO₂
