Answer:

A meteor shower are defined as the celestial event in which a meteor comes from one point in the sky and visible in night sky.

Meteors are also known as Shooting stars as they glow when enters in the Earth surface as glowing streaks, where tail point to the origin in the sky and face faces the Earth surface.

Meteor showers take place when meteoroids entering Earth's atmosphere.

Meteor showers can repeat themselves because it depends on the comet orbits which can take place at the same time each year.

Answer:

[NaOH] = 0.1 Molar ... Note => the brackets around formula;i.e., "[ ]" is generally accepted in the chemistry community as concentration in Molar terms.

Explanation:

The metathesis rxn, or double replacement rxn, equation is:

(Molarity x Volume) of acid = (Molarity x Volume) of base, or

(M·V)acid = (M·V)base => M(base) = M·V(acid)/V(base)

= 0.1M × 18.3ml / 20ml = 0.0915M(base) = 0.1M (1 sig-fig) = [NaOH]

Answer:

Marine animals

Explanation:

A fossil is any remains of ancient life. Fossils can be body fossils, which are remains of the organism itself or trace fossils, such as burrows, tracks, or other evidence of activity(Lumen Learning).

Fossils of land animals are less common because they may not have been buried. However, land organisms may become buried underneath by mudslides or ash from a volcanic eruption, or covered by sand in a sandstorm.

Marine fossils are more common owing to quick burial. Marine animals that die near a river delta may be buried by sediment carried by the river. A storm at sea may shift sediment on the ocean floor, covering and helping to preserve skeletal remains(Lumen Learning).

Answer:

406m/s

Explanation:

Speed = distance ÷ time

Answer:

406 m/s

Explanation:

Divide 325,000 meters by 800 and 800 seconds by 800 (because we are trying to find the speed in meters per second.

325,000÷800 = 406.25 meters

800÷800 = 1 second

Answer: i gotcu the answer is mass

Explanation: The more weight of the object the more its subject to gravity like a feather barley is while a bowling ball smashes into the ground :D

The property allows objects to be subject to gravity is mass. Therefore, option B is correct.

Mass is a physical body's total amount of matter. Inertia, or the body's resistance to acceleration when a net force is applied, is also measured by this term.

The strength of an object's gravitational attraction to other bodies is also influenced by its mass. The kilogram serves as the SI's fundamental mass unit. The amount of matter object present is also known as mass.

The amount of matter that makes up every item or body is the greatest way to understand mass. Everything that we can see has mass. Examples of objects with mass include a table, a chair, your bed, a football, a glass, and even air. The mass of a thing determines whether it is light or heavy.

Thus, option B is correct.

Answer:

Explanation:

Here's the complete question:

A chemist analyzes two samples.One sample contains 14g of element x and 6.0g of element y.The second sample contains 28g of element x and 6.0g of element y. Does it appear that the two samples are the same substance?

The two samples that we are given in the question are different. They are not the same thing because we can deduce that their components ratio are different.

Sample One contains 14g of element x and 6.0g of element y. The ratio of element x to y is 14/6 = 7/3 = 7:3.

Sample Two contains 28g of element x and 6.0g of element y. The ratio of element x to y is 28/6 = 14/3 = 14:3.

Therefore, they have different ratio for their components and are therefore not thesame.

Explanation: an atom increases negative charge put frustration/ stress on other electrons causing alot of energy to be released.

Answer:

5.09 x 10⁶ s⁻¹ = 5.09 x 10⁶ Hz

Explanation:

The relation between frequency (ν) and wavelength (λ) is given by:

λ = c/ν

where c is the speed of light (2.998 m/s) and it is a constant.

So, we first convert the wavelength from nanometers (nm) to meters (m) (1 nm = 1 x 10⁻⁹):

λ= 589 nm x (10⁻⁹ nm/1 m) = 5.89 x 10⁻⁷ m

Then, we calculate the frequency from the equation:

λ = c/ν ⇒ ν = c/λ = (2.998 m/s)/(5.89 x 10⁻⁷ m) = 5.09 x 10⁶s⁻¹ = 5.09 x 10⁶ Hz

Answer:

B

Explanation:

The [tex]\rm \bold{F^1^-}[/tex] is the fluorine anion with 8 valence electrons. Hence, option B is correct.

An ion is defined as the atom with the change in the valence electrons by the loss or gain of electrons to complete the outer shell.

The ions with the gain of electrons result in a negative charge and are termed anions. The ions with a loss of electrons have a positive charge and are termed cations.

The F is the halogen atom of group 17 with 7 valence electrons. The ion formed for F requires 1 electron to complete its valence shell.

The ion [tex]\rm F^1^-[/tex] has a negative charge, which denotes it gains an electron and forms anion.

The gain of electrons results in the number of valence electrons being 8.

Thus, [tex]\rm F^1^-[/tex] is the fluorine anion with 8 valence electrons. Hence, option B is correct.

Answer:

84 g of N₂        

Explanation:

We begin from the reaction:

N₂O₄  +  2N₂H₄ →  3N₂  + 4H₂O

  1st step: Find out the limiting reactant.

We convert the mass to moles.

       276 g . 1mol/ 92g = 3 moles of N₂O₄

64 g . 1mol / 32g = 2 moles of hidrazine  

Limiting reactant is the hydrazine. Ratio is 1:2, then for 3 moles of tetroixde I may need 6 moles of N₂H₄. (But I only have 2).

To determine the grams of produced nitrogen we see stoichiometry (2:3)    

2 moles of hydrazine can produce 3 moles of N₂

Definetaly our 2 moles make 3 moles of gas.

We convert the moles to mass.

3 mol . 28g /1mol = 84 g of N₂

Answer:

31.24 kJ

Explanation:

First we convert 3.00 grams of SiO₂ to moles, using its molar mass:

Now we calculate the heat absorbed, using the given ΔH°:

If the complete reaction of 1 mol of SiO₂ absorbs 624.7 kJ, then with 0.05 mol:

The heat absorbed by 3.00 grams of SiO2 is 31.17 kJ/mol.

The thermochemical equation is;

SiO2(g) + 3C(s) → SiC(s) + 2CO(g) ΔH° = 624.7 kJ/mol

The number of moles of SiO2 = 3.00 g/60.08 g/mol = 0.0499 moles

From the reaction equation;

1 mole of SiO2 absorbs 624.7 kJ/mol

0.0499 moles SiO2 absorbs  0.0499 moles ×  624.7 kJ/mol/1 mole

= 31.17 kJ/mol
