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:
Question 1: What material do you think can be a cheaper and better alternative to kerosene?
Answer: Generic lamp oil can be used to replace kerosene in lamps. The cheaper lamp oil burns cleaner and has less odor than the more expensive kerosene.
Question 2:
Correct answer is the last option

Which ingredients are needed to transform nadp to nadph?.
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."

How many particles or molecules of hydrogen are there in one mole of H2O?
6.022 × 10^23 ×2 = 12.044 × 10^ 23 atoms
Answer:
In one mole of water, there will exist approximately 6.02⋅1023 water molecules. So, there will be a total of 6.02⋅1023⋅2≈1.2⋅1024 hydrogen atoms.

A fusion reaction always creates which of the following?
a A massive amount of energy.
b A massive amount of heat.
C A more massive atomic nucleus.
d A massive number of smaller nuclei.
A fusion reaction can be regarded as the type of reaction that occurs where two lighter elements come together in a type of reaction giving rise to a heavier/more massive element.
A fusion reaction always creates a more massive atomic nucleus (option c).
When the two lighter nuclei comes together in a reaction, a more heavier/massive nucleus is formed but its mass will still be less than the combined mass of the two reactant nuclei.
This also indicates that the left over mass may have been released as energy.

Draw the structure of the product that is formed when the compound shown below is treated with ch3co3h under aqueous acidic conditions.
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.

Two chemicals, Z and X react completely to form a product, Y. If 8.7 grams of x react to produce 19.5 grams of Y, how many grams of Z must have reacted to form this much product?
Answer:
Z= 10.8
Explanation:
The simple formula Z + X = Y can solve this problem. Since we are given that,
X= 8.7 GramsY= 19.5 GramsThen 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.
