More than 7,000 islands in the Philippines lack access to electricity, so after the sun goes down, light usually comes through kerosene lamps. While cheap, these fire hazards are bad for the environment and human health.
You are an entrepreneur and would like to suggest to the government of the Philippines a better solution to this problem. But to come up with the solution to this problem, you must first understand the nature of chemical bonding and factors that control the structure of compounds. You will study and understand natural materials behavior to build a very cheap and environmentally friendly lamp.

What material do you think can be a cheaper and better alternative to kerosene?



Question 2 options:

There is no better alternative to kerosene.


A material that contains ions, so it can conduct electricity.


A material that contains gas, as gases can conduct electricity.


A material having covalent boding.

Answer:

A. Core

Explanation:

The collisions which occur between the hydrogen atoms starts to heat the gas in the cloud. Once the temperature reaches 15,000,000 degrees Celsius, nuclear fusion takes place in the center, or core, of the cloud. The tremendous heat given off by the nuclear fusion process causes the gas to glow creating a protostar.

In a star, nuclear fusion which is a type of  nuclear reaction occurs in the core.

There are two types of nuclear reactions which are nuclear fusion and nuclear fission .They involve the combination and disintegration of the element's nucleus respectively.

In nuclear fission, the nucleus of the atom is bombarded with electrons of low energy which splits the nucleus in to two parts .Large amount of energy is released in the process.It is used in nuclear power reactors as it produces large amount of energy.

In nuclear fusion,on the other hand, is a reaction which occurs when two or more atoms combine to form a heavy nucleus.Large amount of energy is released in the process which is greater than that of the energy which is released in nuclear fission process.

Answer:

according to online:

"Hydrogen ions are transported with the electrons along the chain of reactions. In photosystem I, the electrons are energized, and the energy is stored in molecules of NADP+. During these reactions, the NADP+ molecules are reduced by the addition of electrons. A hydrogen ion is added to NADP+ to form NADPH."

Answer:

Z= 10.8

Explanation:

The simple formula Z + X = Y can solve this problem. Since we are given that,

Then we can just substitute the actually values for the letters.

Z + 8.7 = 19.5

From here, we can just do simple math to find the answer.

Z + 8.7 - 8.7 = 19.5 - 8.7

Z = 10.8

So, 10.8 grams of Z reacted to form the product.

Answer:

Both Iron Man and Spider-Man are quite powerful in the comic books, but we think that Spider-Man would be able to defeat Iron Man. Despite his powers, Iron Man is still just a man in a suit, while Spider-Man has actual superpowers and we think they could easily cancel all of Iron Man's advantages

Explanation:

The structure of the product that is formed is (2R,3S)-hexane-2,3-diol

The missing compound from the given question known as Hex-2-ene is shown with its stick formula in the reactant side of the image attached below.

Alkene reacts with a peracetic acid via the process of epoxidation of alkenes to produce an intermediate known as oxiranes. This intermediate is later being treated with aqueous acid to give a chemical compound with two hydroxyl substituents known as the glycol(diol) family.  

Hex-2-ene reacts with peracetic acid CH₃CO₃H.

During the process of the reaction, an oxygen atom is moved from the peracetic acid to the C = C double bond, generating an oxirane ring.

Here;

Peracetic acid is considered to be an electrophilic oxidizing agent because the transferred oxygen atom has a positive charge.

The intermediate (oxirane) is further reacted with aqueous acid to produce an enantiomer of the diol family.

Sorry I accidentally touched it

Answer:

Charcoal is produced by the incomplete combustion of plant or animal products. The major use of charcoal is for outdoor cooking. The second largest use of charcoal is in industrial applications in the form of activated charcoal. The activation process involves heating the charcoal subjecting it to steam or treating with a chemical to both remove substances that have adhered to it as well as break it down into finer particles and thus increase the surface area. Activated carbon has been used for its adsorptive properties as a ‘universal antidote’ in cases of poisonings, as a filter aid agent, and in decolorization processes.

Answer:

Tthe 3-carbon pyruvate molecule made in glycolysis loses a carbon to produce a new, 2-carbon molecule called acetyl CoA. The carbon that is removed takes two oxygens from pyruvate with it, and exits the body as carbon dioxide (CO 2​start subscript, 2, end subscriptt).

Explanation:

high compressibility is not the property of metal.

This problem is providing the initial volume and pressure of a gas as 675 mL and 1.5 atm and then mentions the final volume as 345 mL and asks for the new pressure of the gas.

Thus, we start off this problem by recalling the concept of Boyle's law as an inversely proportional relationship between pressure and volume:

[tex]P_1V_1=P_2V_2[/tex]

In which we solve for the final pressure, [tex]P_2[/tex] as shown below:

[tex]P_2=\frac{P_1V_1}{V_2} \\\\\\P_2=\frac{675mL*1.5atm}{345mL} \\\\\\P_2=2.93atm[/tex]

Considering we had to cancel out the milliliters to obtain atm as units of pressure.
