The alkenes mentioned above are in order of decreasing stability and increasing energy with Stability the most secure (lowest in energy).
Why is alkene important?Alkenes have a variety of uses in manufacturing. They serve as the raw ingredients for the synthesis of alcohols, polymers, lacquers, detergents, and fuels. Acetylene, propene, and 1,3-butadiene are the three most significant alkenes for the chemical industry.
How alkenes are formed?Elimination processes, which remove two atoms from adjacent carbon atoms to create a double bond, are typically used to create alkenes. Dehydration of alcohols, dehydrohalogenation of halides, and dehalogenation of alkanes are all steps in the preparation process.

If one has molecular weight in Daltons than diffusion or osmosis take place by molecules move around.
What is diffusion?
diffusion is a type of cellular transport. Since the diffusion does not require the energy (ATP) to take the place, it is considered as a form of passive transport. There are three types of diffusion: there are -simple diffusion, osmosis and facilitated diffusion. During the time of diffusion, molecules move from an area of high concentration to an area of the low concentration.
Explanation -
The rate of diffusion is the affected by the molecular weights of the molecules that is diffusing. The heaviest the solutes is, the slower the molecules moveing around. Slower the moving molecules diffuse at it slower rate than faster the moving ones. Molecules are that are lighter move in faster and therefore have an increases speed of the diffusion.

Using what you have learned about the nitrogen cycle, what do you predict are the o2 levels in the river?.
Low - The generation of nitrates (NO 3-) requires oxygen, so the oxygen levels will be low.
What predicts are the o2 levels in the river?.Nitrates are created when oxygen present in water reacts with ammonia. Not the oxygen in the water molecule, but rather the dissolved oxygen is the one that reacts with the ammonia. Aquatic animals breathe in this oxygen to survive. The formation of nitrates will result in a decrease in the amount of dissolved oxygen, which suffocates marine species and has a negative effect on them. This will also damage the ecosystem as a whole.Ammonia reacts with oxygen in water to generate nitrates. It is the dissolved oxygen, not the oxygen found in water molecules, that reacts with ammonia. Low - Oxygen will be in short supply because the production of nitrates (NO 3-) requires it.The complete question is :Nitrates are made by converting ammonia (NH3) to nitrite (NO2-) and then to nitrate (NO3-). What do you predict the O2 levels in the river will be? High - Nitrate (NO3-) contains more oxygen atoms than ammonia (NH3), so the O2 will be high. Normal - Even though oxygen atoms are added to nitrogen during the nitrogen cycle, the levels of O2 in the water will be normal. Low - The generation of nitrates (NO3-) requires oxygen, so the oxygen levels will be low.

What is Molecules?
The smallest unit of a substance that retains its composition and properties is a molecule. It is constructed of two or more atoms connected by chemical bonds.
Atoms are the fundamental unit of an element. They consist of a nucleus that is encircled by electrons. If an atom's electron shell is not quite complete, it is said to have valence electrons. When two or more atoms collaborate to share their valence electrons from the outer shell, a chemical (covalent) relationship is established and a lower energy state is reached. Atomic bonding causes the release of energy in an exothermic reaction.
When only two atoms join, they form diatomic molecules. Carbon monoxide (CO), which consists of a single carbon atom and a single oxygen atom, is an illustration of a diatomic molecule. It is known as a homonuclear diatomic molecule if the two atoms are from the same element, such as oxygen (O2) and nitrogen (N2). More than two atoms make up polyatomic molecules like water (H2O) and carbon dioxide (CO2). Polymers are larger molecules that can contain thousands of atoms.

(d) The photoelectric effect.
Photoelectric effect. So in the experiment, a certain light (i.e. EM radiation) was used to attempt to eject an electron from a metal. If light were a wave, then simply increasing the intensity would increase the energy. However, increasing the intensity of the light did not result in ejection. Only changing the type of light (lower wavelength) worked. This proves light's particle properties. Increasing intensity just increases the number of particles, nothing more. The right energy is needed before intensity becomes a factor. Hope this helped.

c = 3 x 10^8 m/s
μ = c / v
where, μ is the refractive index, c be the velocity of light in air and v be the velocity of light in the medium.
μ = 1.461
1.461 = 3 x 10^8 / v
v = 3 x 10^8 / 1.461
v = 2.05 x 10^8 m /s

which nonrenewable resource cannot be recycled? responses copper copper aluminum aluminum oil oil iron
Oil is a nonrenewable resource that cannot be recycled.
In the field of physics, oil can be described as a source of energy that comes from fossil fuels. All of the energy resources that come from fossil fuels are non-renewable as they are made from the dead remains of plants and animals that died a long time ago.
Among the options provided above, all are metals except oil. Metals can be recycled by burning them and shaping them into something useful.
However, fossil fuel resources cannot be recycled as the ones used are all consumed and burned up into the atmosphere.

What happens to the reactivity left to right in a period?.
In a periodic table, reactivity falls off to the right. A tabular representation of the chemical elements is known as the periodic table, or periodic table of the (chemical) elements.
It is commonly regarded as an icon of chemistry and is utilized extensively in physics, chemistry, and other sciences. Down in periodic table, reactivity lessens. Because group 7 elements get an electron in reaction, this occurs. The quantity of electron shielding rises as you advance down the group, reducing the electron's attraction to the nucleus.
In a period, the reactivity of non-metals rises from left to right, whereas in a group, it falls as we move down the group because the propensity to take electrons declines. Is called as reactivity.

What happens to the reactivity left to right in a periodic table
gizmo warm-up a chemical change, (or chemical reaction) occurs when one or more substances, called reactants, are transformed into different substances, or products. in the chemical changes gizmo, you will look for evidence of chemical changes by looking at changes you can see, touch, or smell. to begin, check that reactant 1 is sodium and reactant 2 is water. sodium is a metal so soft you can cut it with a knife. click play (). what do you observe? the mass increased science. we took sodium and added it to the water. do you think a chemical reaction has taken place? explain.
When water and sodium react, caustic soda (NaOH) and hydrogen gas are produced.
Reaction of sodium and waterWater-insoluble hydrogen gas is formed and enters the atmosphere, so bubbles are observed coming out of the water when sodium reacts with it.
reaction product
Metallic sodium reacts rapidly with water to form caustic soda (NaOH) and hydrogen gas (H2). Since this chemical reaction is an exothermic reaction in which a large amount of heat is released from the solution, we can conclude that sodium hydroxide solution and hydrogen gas are formed by the reaction of water and sodium.
