Is Hydrogen gas a fuel alternative?
Yes, hydrogen gas can be used as a fuel alternative. It can be used in fuel cells to produce electricity to power vehicles or other applications, emitting only water as a byproduct. However, challenges remain in terms of production, storage, and infrastructure for widespread adoption.
Why is it important to use alternative resources in place of fossil fuels?
It is important to use alternative resources in place of fossil fuels to reduce greenhouse gas emissions and combat climate change. Alternative resources such as solar, wind, and hydroelectric power are renewable and produce less pollution than fossil fuels, leading to a cleaner and more sustainable energy future. Additionally, transitioning to alternative resources can help reduce dependence on imported fossil fuels and enhance energy security.
How can water be split to produce hydrogen and oxygen gas?
Water can be split to produce hydrogen and oxygen gas through a process called electrolysis. In electrolysis, an electric current is passed through water, causing the water molecules to break apart into hydrogen and oxygen gas. This process requires a source of electricity and electrodes to facilitate the reaction.
Does hydrogen combustion produce carbon?
No, burning hydrogen produces only water, it does not produce carbon or carbon dioxide.
Explain what is meant by the basic economic problem?
Economic problem is the problem regarding allocation of limited resources for the production of alternative goods and services. in other words, economic problem is the 'problem of choice'. Since the resources are scarce and they have alternative uses, there arises the problem of choice regarding the use of these resources. The law of scarcity states that goods are scare because there are not enough resources to produce all goods that people want to consume. Thus, Economic Problem is the 'problem of relative scarcity' and the 'problem of choice' arising therefrom.The basic economic problems of an economy are given below:What to produce and how much to produce?How to produce?For whom to produce?Problem of fuller utilisation of resources.Problem of efficiency in utilisation of resources.Problem of economic growth.
Does the sun produce hydrogen?
No. It uses hydrogen during nuclear fusion to produce helium.
Why is bamboo sustainable and how does it contribute to environmental conservation?
Bamboo is sustainable because it grows quickly, requires minimal water and pesticides, and can be harvested without harming the environment. It contributes to environmental conservation by absorbing carbon dioxide, preventing soil erosion, and providing a renewable alternative to wood and other materials that require more resources to produce.
What is Irrigation used for in Portugal?
Growing agricultural crops in fields that lack the natural resources to house the species of produce that the owner requires. Much like anywhere else.
How much hydrogen would be required to produce 7.5 mol of water?
To produce 1 mol of water, 2 mol of hydrogen is needed. Therefore, to produce 7.5 mol of water, you would need 15 mol of hydrogen.
What chemicals produce hydrogen gas?
Water. When you put electrodes into water and pass a current, you produce hydrogen and oxygen gasses.
