Answer:

The gravitational pull of a black hole is so strong that nothing, not even light, can escape once it gets too close. ... Moving at close to the speed of light, these particles ricochet off the event horizon and get hurled outward along the black hole's axis of rotation

Temperature is the awnser

Answer: 6 moles of Carbon.

Explanation: One mole of Carbon is equal to 12 grams of Carbon, so you would divide 72 by 12 and the answer would be 6.

Answer:

Since you didnt get asked for a spefic weight of gold lets assume it was 5g

Explanation:

5g Au/197 =.02538 mols in 1 liter of sea water is

.02538/1L which gives you a Molarity of .012538 assuming 5g if they ask for a different number just replace 5 with any weight in grams

Answer:

The boiling point of the halogens increases as you go down the group. The halogens exist as diatomic molecules, with both atoms sharing an electron to completely fill the outer shell. The increase in boiling (and melting point) can be attributed to the increase in intermolecular forces (van der Waals).tion:

the rest dont sound as reasonable to me so i would say C

Explanation:

Answer:

Gravity, or gravitation, is a natural phenomenon by which all things with mass or energy—including planets, stars, galaxies, and even light—are brought toward one another. On Earth, gravity gives weight to physical objects, and the Moon's gravity causes the ocean tides.

Gravity, also called gravitation, in mechanics, the universal force of attraction acting between all matter. ... On Earth all bodies have a weight, or downward force of gravity, proportional to their mass, which Earth's mass exerts on them. Gravity is measured by the acceleration that it gives to freely falling objects

The gravitational force is a force that attracts any two objects with mass. We call the gravitational force attractive because it always tries to pull masses together, it never pushes them apart. In fact, every object, including you, is pulling on every other object in the entire universe!

Gravitational force is the force that attracts to objects with mass. ... This forces tries to pull masses together, that is why attractive in nature. For example: When ball is thrown upwards it always come downwards after a certain height because the ball is pulled or attracted by the Earth's gravitation la force.

Good Question!!! No one has found the answer to that question.

Explanation:

Answer:

The three main rock types are igneous, metamorphic and sedimentary. The three processes that change one rock to another are crystallization, metamorphism, and erosion and sedimentation. Any rock can transform into any other rock by passing through one or more of these processes. This creates the rock cycle.

Frictional force between two objects can be increased by:

i) making the surfaces rough

ii) increasing the mass of the object that ks moving.

Answer:

D. gain one electron

Explanation:

In order to become a chemically stable ion, a neutral atom of sodium will gain one electron. Therefore, the correct option is option D.

Chemical stability in chemistry refers to a chemical system's thermodynamic stability. When a system reaches its lowest energy state or in thermodynamic equilibrium with its surroundings, thermodynamic stability occurs.

It could be a spontaneous process when the total number of atoms or molecules in a given shape is conserved despite the fact that individual particles or atoms change forms. In order to become a chemically stable ion, a neutral atom of sodium will gain one electron.

Therefore, the correct option is option D.

Answer:

Fe is the limiting reagent

Explanation:

In a chemical reaction, the limiting reactant, also known as the limiting reagent. Therefore, the correct option is option C.

In a chemical reaction, the limiting reactant, also known as the limiting reagent, controls how much product is produced. Calculating the percentage value of a reaction is achievable if the limiting reactant has been identified.

Because elements and compounds in an equilibrium chemical equation react in accordance with their mole ratios, there must be a limiting reactant. Therefore, when one of the reactants was present in a larger amount than the other and the mole ratio inside the balanced equation specifies that it takes 1 mole from each reactant to generate a product, the reactant existing in the lesser amount would be the limiting reactant.

4Al[tex]_2[/tex]O[tex]_3[/tex] + 9Fe [tex]\rightarrow[/tex] 3Fe[tex]_3[/tex]O[tex]_4[/tex] + 8A|

moles of Al[tex]_2[/tex]O[tex]_3[/tex] = 10.2 /101.96

                            =0.10moles

moles of Fe = 11.2/55.8

                   =0.20

Fe is the limiting reagent

Therefore, the correct option is option C.

When a metal reacts with water, a metal hydroxide and hydrogen are formed. Sodium reacts vigorously with water.

Answer: Hydrogen Gas ( H2)

Explanation: When metals react with water they form hydrogen gas which actually react and start to burn and make squeaky pop noises.

Answer: 0.45 moles of [tex]H_2O[/tex] will be produced from 0.15 moles of propanol.

Explanation:

The balanced chemical reaction is:

[tex]2C_3H_6O+8O_2\rightarrow 6CO_2+6H_2O[/tex]

[tex]C_3H_6O[/tex] is the limiting reagent as it limits the formation of product and [tex]O_2[/tex] is the excess reagent.

According to stoichiometry :

2 moles of [tex]C_3H_6O[/tex]produces = 6 moles of [tex]H_2O[/tex]

Thus 0.15 moles of [tex]V[/tex] will produce=[tex]\frac{6}{2}\times 0.15=0.45moles[/tex]  of [tex]H_2O[/tex]

Thus 0.45 moles of [tex]H_2O[/tex] will be produced from 0.15 moles of propanol.
