Taking into account the reaction stoichiometry, the theoretical yield of oxygen when 29.2 g of water are decomposed by electrolysis is 25.956 grams.
Reaction stoichiometryIn first place, the balanced reaction is:
2 H₂O → 2 H₂ + O₂
By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:
H₂O: 2 molesH₂: 2 molesO₂: 1 moleThe molar mass of the compounds is:
H₂O: 18 g/moleH₂: 2 g/moleO₂: 32 g/moleThen, by reaction stoichiometry, the following mass quantities of each compound participate in the reaction:
H₂O: 2 moles ×18 g/mole= 36 gramsH₂: 2 moles ×2 g/mole= 4 gramsO₂: 1 mole ×32 g/mole= 32 gramsDefinition of theorical yieldThe theoretical yield is the amount of product acquired through the complete conversion of all reagents in the final product, that is, it is the maximum amount of product that could be formed from the given amounts of reagents.
Theorical yield of O₂The following rule of three can be applied: if by reaction stoichiometry 36 grams of water form 32 grams of oxygen, 29.2 grams of water form how much mass of oxygen?
[tex]mass of oxygen=\frac{29.2 grams of waterx32 grams of oxygen}{36 grams of water}[/tex]
mass of oxygen= 25.956 grams
Finally, the theoretical yield of oxygen when 29.2 g of water are decomposed by electrolysis is 25.956 grams.

What is the significance of a gene?Immersive Reader
Explanation:
A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Every person has two copies of each gene, one inherited from each parent. Most genes are the same in all people, but a small number of genes (less than 1 percent of the total) are slightly different between people. These small differences contribute to each person’s unique physical features.

Explanation:
A student tests the pitch of different-sized rubber bands by stretching them around a box and then plucking them. What pitch does a thick rubber band have, and why?
A thick rubber band vibrates fast, so it produces a low pitch sound.
A thick rubber band vibrates fast, so it produces a high pitch sound
A thick rubber band vibrates slowly, so it produces a low pitch sound.
A thick rubber band vibrates slowly, so it produces a high pitch sound.
Answer:
your answer will be C
Explanation:
remember low souunds carry sound waves farther than high pithed sounds.
Answer:d or I
Explanation: remember they have sound waves so if it’s slow, then is a high pitch

When mineralization occurs, what is the nature of the fossilized material?
Answer:
Fossils could be anything dug up from the ground, including crystals or human artifacts, but some of these objects aren't organic. Among the ones that were organic, they turned into a recognizable resemblance to living organisms.
Explanation:
there you go
Answer: here is an example
Explanation:
A common mode of fossilization is mineralization, the replacement of organic material by inorganic minerals. The most common dinosaur fossils are the mineralized remains of bones and teeth. Bones are composed of calcium phosphate and organic material. Common mineralizing media are calcite, iron minerals, and silica.

Why does a carrot appear to be orange under white light?
Answer:
yesh it is many many apper indiology from whight ho4P + 5O2 → P4O10 How many phosphorus (P) atoms are on each side of the equation? How many oxygen atoms are on each side?
Answer:
4 p and 10 O on both sides
Explanation:
on the reactant side you can see easily that there are 4 P. With the oxygen on the reactant side you take the coefficient (5) times the subscript (2) which gives a total of 10 Oxygens.
On the product side there is a subscript of 4 next to the p, and a subscript of 10 next to the O
They are equal on both sides so you are done.
Jenna notices that the speed of the wind has increased throughout the day. What is causing the faster wind?
There has been no precipitation.
The difference in air pressure has decreased.
The difference in air pressure has increased.
The direction of the wind has changed to the south.
The speed of the wind has increased throughout the day as there has been no precipitation.
What is precipitation?Precipitation is a process in which vapor of liquid changes into small droplets.
In the day time temperature of the atmosphere is high as compare to the night, so rate of precipitation is low at the day time due to which speed of the wind has increased as compare to the night time.
Hence, option (a) is correct i.e. there is no precipitation.

A(n)_______________wave can travel through empty space or through matter.
There are_____________types of wave motion-transverse ________________, and a comination of both.
This is about WAVE and this is SCIENCE
Answer:
For the first one it is Electromagnetic waves and the second one is longitudinal and transverse and water water waves (I’m sorry if I get the second one wrong for you but the first I put is right)
Explanation:
An electromagnetic wave can travel through empty space or through matter.There are 2 types of wave motion-transverse ,longitudinal and a combination of both.
What is an electromagnetic wave?The electromagnetic radiation consists of waves made up of electromagnetic field which are capable of propogating through space and carry the radiant electromagnetic energy.
The radiation are composed of electromagnetic waves which are synchronized oscillations of electric and magnetic fields . They are created due to change which is periodic in electric as well as magnetic fields.
In vacuum ,all the electromagnetic waves travel at the same speed that is with the speed of air.The position of an electromagnetic wave in an electromagnetic spectrum is characterized by it's frequency or wavelength.They are emitted by electrically charged particles which undergo acceleration and subsequently interact with other charged particles.
