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.

In 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:

The molar mass of the compounds is:

Then, by reaction stoichiometry, the following mass quantities of each compound participate in the reaction:

The 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.

The 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?

\(mass of oxygen=\frac{29.2 grams of waterx32 grams of oxygen}{36 grams of water}\)

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.

Answer:

The acid in the soil

Explanation:

The more acid the bluer in terms of hydrangea flowers if there was a balance between the two it will be half and half of the two colors.

Answer:

Since the hydrangeas are changing color depending on whether the soil is acidic or basic, they must have an indicator. This means that any hydrangea planted in acidic soil will have blue flowers and any hydrangea planted in basic soil will have pink. One common indicator present in many plants is anthocyanin, so maybe hydrangeas contain that chemical.

In mathematics, an ellipse is a plane curve surrounding two focal points, such that for all points on the curve, the sum of the two distances to the focal points is a constant. As such, it generalizes a circle, which is the special type of ellipse in which the two focal points are the same.

Maybe they might use that math thing for Science.

Answer:

The full valence electron shells of these atoms make noble gases extremely stable and unlikely to form chemical bonds because they have little tendency to gain or lose electrons. Although noble gases do not normally react with other elements to form compounds, there are some exceptions

Explanation:

In the Periodic Table, The elements of group 18 are all gases, but there are highly unreactive. That's why, they are called Noble Gases. The cause of there inertness is: Electronic Configuration

Answer: Clothes purely made of synthetic fibers are not comfortable in a hot and humid environment as they don't have the property to absorb water or sweat quickly so their water-resistant property makes them unsuitable for hot humid environment .

Explanation:

Mixing of synthetic fiber and natural fibers enhances the properties such as strength, elasticity, and ease of ironing and washing. Generally in hot environments it is preferred to wear a mixture of synthetic and natural fiber than wearing only clothes made from synthetic fiber .

Moreover, mixing synthetic fibres with natural fibres enhances their properties, such as strength, elasticity and ease of washing and ironing. Hence, these days clothes made out of a mixture of synthetic fibres and natural fibres are more popular than those made purely out of synthetic fibres.

Answer:

a force is any interaction that is unchallenged will change the motion of an object you might have heard of the push pull example

Explanation:

The equation to find force is

force = mass * acceleration or F = M * A

Force never creates motion!! although motion can occur

force is measured in the SI unit of newtons

a good example would be kicking a football when the foot ball is kicked your foot is interacting with the ball the ball is the object and your foot is the motion that is pushing on the ball which will then make the ball accelerate in the air so i think to find the force of the ball you take the mass of the object in this case the ball and multiply it by it acceleration or the change in its velocity to get force

Answer:

sugar-water is a mixture not a compound.(homogeneous mixture.)

Explanation:

Compounds are substances formed by the chemical combination of two or more elements. Mixtures are substances formed by physically mixing two or more substances together.

The solution of sugar in water is considered a mixture not a compound because the particles of sugar and water are not completely dissolve nor mixed in a fixed proportion or ratio. hope this helped :)

Answer: Which pairs are homologous - structures? The arm of a human, the wing of a bird or a bat, the leg of a dog and the flipper of a dolphin or whale, In short term it is having the same relative position, value, or structure

Which pairs are analogous structures? - Examples of analogous structures range from wings in flying animals like bats, birds, and insects, to fins in animals like penguins and fish.  Also in short term it means comparable in certain respects, typically in a way which makes clearer the nature of the things compared.

Explanation: I do believe cats since bats actually belong to the super-order Pegasoferae, which contains horses, cats and dogs, cows, whales and hedgehogs.

Explanation:

Answer:  Mountains block the winds that bring rain clouds.

Explanation: By acting as obstacles to the flow of air masses, mountains contribute significantly to the dryness of deserts. Orographic lifting is a process that occurs when moist air is forced to ascend as it approaches a mountain range. The moisture in the air condenses and forms clouds as the air cools as it climbs. As a result, on the windward side of the mountains, the air loses a lot of its moisture as precipitation. The air has already lost a significant amount of moisture by the time it reaches the leeward side of the mountains, creating a rain shadow effect. On the leeward side of the mountains, this impact results in a dryer area that is often a desert. Consequently, the existence of mountains influences

Not a straight up answer, but moreover to help you get it: (Circuit Boards)

Aside from the tasks it performs, perhaps the most important function of a circuit board is providing a way to integrate the electronics for a device in a compact space. A PCB allows components to be correctly connected to a power source while being safely insulated. Also, circuit boards are less expensive than other options because they can be designed with digital design tools and manufactured in high volume using factory automation.

Copper(II) chloride is the chemical compound with the chemical formula CuCl 2. This is a light brown solid, which slowly absorbs moisture to form a blue-green dihydrate.

Etching helps us to see the structure of the atoms of copper.

The term etching refers to the process by which we expose the inner structure of copper. It is usually done electrically or by the use of an acid. The surface of the copper is removed and the inner structure of the copper is shown.

As such, when you etch copper, you can see the inner structure such as the arrangement of the atoms of copper and how they fit together.

As such looking through the etched copper would help you to appreciate that matter is composed of atoms.

Answer:

In carbon cycle, carbondioxide gas is present in the atmosphere. This carbondioxide gas is taken inside by the plant body through stomata and made food from it. When this food is eaten by animals, this carbon is transferred to their bodies. During breathing, carbondioxide gas is removed from animal body and the carbondioxide gas again goes to the atmosphere.

Explanation:

Answer:

The carbon cycle is similar to the water cycle!

Explanation:

The water cycle shows us that water on Earth isn't destroyed or created, it simply moves around in different forms. Carbon is like that too, but except becoming droplets and clouds it passes through stages where it can exist in the ground as things like coal and be burnt where it will then move into the atmosphere as a gas, until eventually that gas is used to grow a plant. Eventually, that plant will be eaten by an animal, and when that animal dies it goes into the ground once again. Hence, the carbon is always there, just going throughout the planet in different forms.
