Why is hydrogen a “cleaner” fuel source than gasoline?

hydrogen is natural created and in the air already, gas is a fossil fuel and is killing the Ozone layer.  carbon dioxide is a poison and can really harm us and the world.

this paragraph basically explains the question

Compared to the carbon dioxide that is produced when we burn gasoline, ethanol, and other carbon-containing fuels, the water produced by burning hydrogen has a less harmful effect on Earth’s climate. If we can power our cars with hydrogen without producing carbon dioxide, then why don’t more vehicles use hydrogen fuel? Unfortunately, the technology needed to use hydrogen as a fuel is expensive, and storing hydrogen fuel can be difficult. Also, the most common way of getting pure hydrogen is by separating it from substances that contain carbon—so although burning hydrogen fuel does less harm to Earth’s climate than burning carbon-containing fuels, the production of hydrogen fuel is still a problem for scientists trying to reduce climate change.

Answer:

200 grams is the mass of 15% of the solution of lime that is formed by dissolving 30g of calcium hydroxide in water.

Explanation:

Mass of solution = M

Mass percentage of the solution of lime = 15%

Mass of lime or calcium hydroxide = m = 30 g

The Formula of mass percentage is given as :

m/m\%=\frac{m}{M}\times 100

On substituting the values in ab above formula :

15\%=\frac{30 g}{M}\times 100

M=\frac{30 g}{15}\times 100=200 g

200 grams is the mass of 15% of the solution of lime that is formed by dissolving 30g of calcium hydroxide in water.

In what way may drugs be used to affect neurotransmitters?
Orlov [11]
Drugs interfere with the way neurons send, receive, and process signals via neurotransmitters. Some drugs, such as marijuana and heroin, can activate neurons because their chemical structure mimics that of a natural neurotransmitter in the body. This allows the drugs to attach onto and activate the neurons. Although these drugs mimic the brain’s own chemicals, they don’t activate neurons in the same way as a natural neurotransmitter, and they lead to abnormal messages being sent through the network.

Other drugs, such as amphetamine or cocaine, can cause the neurons to release abnormally large amounts of natural neurotransmitters or prevent the normal recycling of these brain chemicals by interfering with transporters. This too amplifies or disrupts the normal communication between neurons.

An invasive species is a species that disrupts the ecosystem into which it is introduced by displacing species.
sveta [45]

Invasive species can do all sorts of damage to an existing ecosystem, including changing habitats and starving native animals of food and resources.

<h3>What is an invasive species?</h3>

An invasive species is an organism that causes ecological or economic harm in a new environment where it is not native.

Invasive species can change the food web in an ecosystem by destroying or replacing native food sources. The invasive species may provide little to no food value for wildlife. Invasive species can also alter the abundance or diversity of species that are important habitats for native wildlife.
