Annalise observes a streak of light in the sky and says she is seeing a shooting star. What is she most likely observing?
a falling star
an asteroid
a meteor
a dwarf planet
Answer: A Meteor
Explanation:
A streak of light in the sky and says she is seeing a shooting star. She's most likely observing is a meteor. Therefore, option C is correct.
What is a meteor ?A meteor is an object from space or a meteoroid that touches down on Earth. The air on the space rock creates drag that causes it to become incredibly heated as it falls toward Earth.
When the earth travels through cometary debris during its orbit around the Sun, meteor showers will result. Although the Earth's orbit around the Sun is nearly round, the majority of comets have very elliptical orbits.
A meteoroid becomes a meteor, or a streak of light in the sky, if it gets close enough to Earth and enters its atmosphere. These light striations are sometimes referred to as "shooting stars" due to their appearance. However, stars are not what meteors are.
Thus, option C is correct.

Explain the term catalyst and how it affects the rate of a chemical reaction.
Answer:
Catalyst. A catalyst speeds up a chemical reaction, without being consumed by the reaction. It increases the reaction rate by lowering the activation energy for a reaction. Energy diagrams are useful to illustrate the effect of a catalyst on reaction rates.

Which noble gases is closest to magnesium? On the periodic table? What must happen if a magnesium atom for it to have an electron arrangement similar to that of a noble gas?
Answer:
Neon and loose electrons
Explanation:
Magnesium has an electron configuration of 2e 8e 2e, and Neon is 2e,8e. For Mg to have a similar electron arrangement it must loose its two valence electrons and make it an ion.
Answer:
Noble neon gas is the closest.
Explanation:
noble Neon gas
The Magnesium would have to lose two electrons
how many molecules are in CO²
Answer:
53.11× 10²³ molecules
Explanation:
Given data:
Number of molecules of CO₂ = ?
Mass of CO₂ = 388.1 g
Solution:
Formula:
Number of moles = mass/ molar mass
Molar mass of CO₂ = 12× 1 + 16×2
Molar mass of CO₂ = 44 g/mol
Now we will put the values in formula.
Number of moles = 388.1 g/ 44 g/mol
Number of moles = 8.82 moles
Now we will calculate the number of molecules by using Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.
The number 6.022 × 10²³ is called Avogadro number.
1 mole = 6.022 × 10²³ molecules
8.82 mol × 6.022 × 10²³ molecules / 1 mol
53.11× 10²³ molecules
Brainliest plz?
Answer:
Now times by Abogadros constant: 1* 6.022*10^23=6.022*10^23 molecules of CO2 are present.
Explanation:
We know the molar mass of CO2(g) is 44.01⋅g⋅mol−1 . And so Avogadro's number of carbon dioxide molecules have this mass... And we take the product of the quotient... Molecules of carbon dioxide=5.00⋅mol×6.022×1023⋅mol−1≅30×1023⋅carbon dioxide molecules.
Where in equation for photosynthesis does carbon dioxide belong
Answer:
The equation for photosynthesis is 6 CO2 + 6 H2O + light --> C6H12O6 + 6 O2, so carbon dioxide will be found in the reactant part of the equation.

Suppose that a TLC plate is spotted with samples 1.0 cm above the bottom of the plate. Select the consequence of inserting the plate into a developing chamber containing a pool of developing solvent that is 1.2 cm deep
(a) The compounds in the samples will leach into the pool of developing solvent resulting in poor resolution.
(b)The pencil marks will dissolve into the developing solvent.
(c)The increased capillary action will cause the compounds to migrate up the plate more quickly.
(d)The increased depth of developing solvent will result in better resolution of the compounds in each sample.
Answer:
The compounds in the samples will leach into the pool of developing solvent resulting in poor resolution.
Explanation:
The aim of thin layer chromatography is the separation of a mixture. Usually, the stationary phase is spotted with the mixture. A mark is made with a pencil at the point to be spotted.
It is necessary to note that the solvent must be below the spot where the mixture is. This is because, if the solvent is above the spot of the mixture to be separated, the components of the mixture will dissolve away in the solvent resolution in poor separation. This is exactly what will happen when the sample is spotted at 1.0 cm above the bottom when the solvent is 1.2 cm above the bottom.

Which example best demonstrates stewardship of the atmosphere
Incomplete question. However, I provided a specific example of stewardship of the atmosphere.
Explanation:
First, note that the term stewardship refers to the belief that humans are obligated to take care and look after our environment (which includes the atmosphere.
An example of this is: deciding to change our mode of transportation: What this entails is that we may decide to switch to riding a bicycle to places rather than going by car. By so doing you will be reducing the number of greenhouse gases emitted into the environment as bicycles do not emit harmful gases when used.
