Many ladybird beetles live in Pedro's garden. He observed them one summer for a science project. Pedro noticed that all the ladybird beetles had red shells. Some of the beetles had many dark spots, some had only a few dark spots, and one or two beetles had no dark spots at all. Around the same time, Pedro's father replanted the garden using just red flowers. A few years later, Pedro observed the ladybird beetles again. This time he noticed that almost all the ladybird beetles had shells with more red visible. They had few or no dark spots on their shells. Pedro concluded that replanting the garden with red flowers caused a change in the ladybird beetle population. Which best explains Pedro's observations?

Answers

Answer 1

Answer:

No.

Explanation:

No, Pedro's observations does not suggest that replanting the garden with red flowers caused a change in the ladybird beetle population because the colour of flower has no effect on the change in the population of ladybird beetle, it must be occur due to the dominant genes present in the population of ladybird beetle. This dominant genes is responsible for the presence of more red colour on the ladybird beetles shells.

What would be the mass, in grams, of 1.505 x 10^23 molecules of carbon disulfide (CS2)?

Answers

To Find :

The mass, in grams, of [tex]1.505 \times 10^{23}[/tex] molecules of carbon disulfide (CS₂).

Solution :

Molecular mass of CS₂ = 76 gm/mol .

It means that mass of [tex]6.022 \times 10^{23}[/tex] molecules of CS₂ is 76 gm/mol.

Let, mass of [tex]1.505 \times 10^{23}[/tex] molecules of carbon disulfide (CS₂) is x.

So,

[tex]x= 76\times \dfrac{1.505 \times 10^{23}}{6.022\times 10^{23}}\\\\x = 76 \times \dfrac{1.505}{6.022}\\\\x = 19 \ gm[/tex]

Therefore, the mass in gram is 19 gm.

how does atomic radius affect coulombic attraction?

The bigger the size of the atom, the electrons, especially the valence electrons are further away from the nucleus. The nucleus is not able to pull the electrons, that are in orbitals further away from the nucleus, towards itself and the coulombic attraction decreases.

Why is sublimation such a critical component for the water cycle in cold climates?

Answers

The air is so dry that when it hits a snowpack, the frozen water evaporates, going directly from the ice to vapor and bypassing the liquid phase entirely. This is called sublimation, and it's a common way for snow to disappear in the arid West."

Answer:

Sublimation is the transition in physical state from solid (ice) to vapor with no intermediate liquid stage. In other words, the ice becomes water vapor without melting. Ideal weather conditions would be low humidity (to allow vaporization), high altitude (lower air pressure facilitates the transition), and strong sunlight (to provide the energy for the transition). High snow-packed mountain ranges offer all of these conditions. Since the temperature is too cold for evaporation, sublimation is needed to provide enough water vapor to feed the water cycle and promote precipitation elsewhere on the planet. Without it, the water would stay frozen in the snow and ice and reduce the amount of liquid water that would replenish the planet.

Which of the following elements is the least reactive metal? Sodium, Rubidium, Chlorine, and Magnesium.​

Answers

First off chlorine is not a metal so you can ignore that one.

Sodium and Rubidium are in group 1 of the periodic table and Magnesium is in group 2.

Group one metals are more reactive than group two because it is harder for the group two metals to lose their 2 valence (outer most) electrons.

As you go down group 1 there is an increase in the reactivity this is because as you go down there is an increase in the atomic radius which leads to more shielding. This weakens the electrostatic forces of attraction making it easier to lose the outermost electrons, therefore they are more reactive.

Answer:

Magnesium

Answers

Answer: Yes- Rusting is an oxidation reaction. The iron reacts with water and oxygen to form hydrated iron(III) oxide, which we see as rust. Iron and steel rust when they come into contact with water and oxygen – both are needed for rusting to occur. Rusting is an example of a chemical change. A chemical property describes the ability of a substance to undergo a specific chemical change. A chemical property of iron is that it is capable of combining with oxygen to form iron oxide, the chemical name of rust.
