Answer: Electrolysis is passing an electric current through a liquid containing ions so that decomposition reaction takes place.
Electrolysis is passing an electric current through a liquid containing ions so that decomposition reaction takes place.When an electric current is passed through acidified water, it decomposes to give hydrogen and oxygen gas. The hydrogen gas is obtained at the cathode and the oxygen gas is obtained at the anode.

Si se hace reaccionar CH3CH3 (etano) con cloro, en presencia de luz ultravioleta, los productos obtenidos en este paso son
Answer:
La reacción de etano, CH₃CH₃ y cloro, Cl₂ en presencia de luz solar se conoce como reacción de halogenación.
Los radicales de cloro se forman cuando el cloro se expone a la luz solar a continuación;
Cl₂ → 2Cl *
Se forma un radical etano cuando el etano, C₂H₆ reacciona con un radical libre de cloro, Cl *, como sigue;
C₂H₆ + Cl → C₂H₅ * + HCl
Se forma un producto halogenado cuando un radical libre de etano reacciona con una molécula de cloro como sigue;
C₂H₅ * + Cl₂ → C₂H₅Cl + Cl *
Un producto halogenado puede reaccionar además con un radical libre para producir como sigue;
C₂H₅Cl + Cl * → C₂H₅Cl₂

what type of volcanic eruption produce ash fall?
Explanation:
I would say explosive eruptions caused by decompression of the dissolved gases in the magma. The Mt Pinatubo eruption is an example of a massive ash fall that eventually closed down an American base in the Philippines. And just recently the island of St. Vincent suffered major damage from ash fall due to a volcanic eruption.

Reaction of hypochlorous acid and ammonia is product-favored system at equilibrium. Answer A: Reaction of hypochlorous acid and ammonia is product-favored system at equilibrium. A Reaction of hypochlorous acid and ammonia is reactant-favored system at equilibrium. Answer B: Reaction of hypochlorous acid and ammonia is reactant-favored system at equilibrium. B Reaction of hypochlorous acid and ammonia yields pH 7.00. Answer C: Reaction of hypochlorous acid and ammonia yields pH 7.00. C No reaction occurs between hypochlorous acid and ammonia. Answer D: No reaction occurs between hypochlorous acid and ammonia. D Further data are needed to draw a conclusion about a prospective reaction.
Answer:
A. True
B. False
Explanation:
Reaction between hypochlorous acid and ammonia does not yields a Ph value of 7.00 , this value is defined to water and no other reaction can yield exactly this Ph value. The acid reaction will give a Ph value below 7 while a base reaction will give Ph value of above 7.

What important points do you need to remember about combustion?
Explanation:
A substance burning in the presence of oxygen and leads to the formation of heat and light is called combustion.
Some important points about combustion are as follows:
Fuel should be present for burning.Air should be present for the supply of oxygen.There should be heat (or ignition temperature) to initiate the chemical reaction.How many Carbon Atoms are there on the PRODUCT SIDE
Answer: There are 6 carbon atoms on the product side.
Explanation:
The given reaction equation is as follows.
[tex]6CO_{2} + 6H_{2}O \rightarrow C_{6}H_{12}O_{6} + 6O_{2}[/tex]
Species present on the left side of an arrow in a chemical equation depicts the reactants.
Species present on the right side of an arrow in a chemical equation depicts the products.
Hence, products in the given reaction equation are [tex]C_{6}H_{12}O_{6}[/tex] and [tex]6O_{2}[/tex].
Therefore, there are 6 carbon atoms present on the product side.
Thus, we can conclude that there are 6 carbon atoms on the product side.

What makes radioisotopes useful for dating objects?
O A. They have unique emission spectra.
O B. They decay at a predictable rate.
C. Their decay products are easy to detect.
O D. They all have extremely long half-lives.
Answer:A
Explanation:
Option D. They all have extremely long half-lives makes radioisotopes useful for dating objects.
What are radioisotopes?Radioisotopes exist as radioactive isotopes of an element. They can also be described as atoms that include an unstable combination of neutrons and protons, or surplus energy in their nucleus.
A radionuclide exists as a nuclide that contains excess nuclear energy, causing it unstable. This excess energy can be utilized in one of three methods: emitted from the nucleus as gamma radiation; assigned to one of its electrons to terminate it as a conversion electron; or utilized to create and emit a unique particle from the nucleus.
Radioactive isotopes of radium, thorium, and uranium, for example, exist found naturally in rocks and soil. Uranium and thorium also happen in trace amounts in water. Radon, induced by the radioactive decay of radium, stands present in the air.
Hence, Option D. They all have extremely long half-lives makes radioisotopes useful for dating objects.

3. What are the planets called that are mostly made of gas?
Explanation:
The gas planets are Jupiter, Saturn, Uranus and Neptune.
Answer:
A gas giant is a large planet composed mostly of gases, such as hydrogen and helium, with a relatively small rocky core. The gas giants of our solar system are Jupiter, Saturn, Uranus and Neptune. These four large planets, also called jovian planets after Jupiter, reside in the outer part of the solar system past the orbits of Mars and the asteroid belt. Jupiter and Saturn are substantially larger than Uranus and Neptune, and each pair of planets has a somewhat different composition.Although there are only four large planets in our solar system, astronomers have discovered thousands outside of it, particularly using NASA's Kepler Space Telescope. These exoplanets (as they are called) are being examined to learnmore about how our solar system came to be.Explanation:

A
0.4 g granulated sugar
B
0.2 g powdered sugar
C
0.4 g powdered sugar
D
0.2 g sugar cube
Answer:
b because it is just 0.2 g and powdered sugar has more contact surface than granulated sugar or sugar cube
The solubility can be given as the amount of solute that can be dissolved in the 100 ml of the solution. The most rapidly dissolved sugar in water is 0.2 gram powdered sugar.
What is a contact surface?The contact surface can be given as the area of the compound that is in direct contact with the solution.
The solubility of the compound is found more in the solute with increased surface area.
The surface area of powdered sugar will be maximum, as more granules of the sugar will be in contact with the water than the cube or the granulated sugar.
Thus, the most rapid dissolution in water is found with 0.2 grams of powdered sugar. Thus, option B is correct.
