Which fules causes minimum enviromental polloution?
Renewable fuels, such as solar, wind, and hydropower, cause minimum environmental pollution as they produce little to no greenhouse gas emissions or air pollutants during operation. These fuels are sustainable and have a low environmental impact compared to fossil fuels.
Which fuel causes minimum environmental pollution. A hydrogen B coal C diesel D kerosene?
hydrogenA2:Coal is the fuel that produces the least pollution among the choices. Hydrogen would be the least polluting except for the reality that hydrogen is produced by burning coal to produce electricity to electrolyse water. Only if the electricity used to produce the hydrogen were produced by hydro, wind or solar, would hydrogen be less polluting than coal.
Which of the following fuels causes minimum environmental pollution?
Among the given options, solar power causes minimum environmental pollution as it does not emit any greenhouse gases or air pollutants during electricity generation. It is a clean and renewable energy source that has minimal impact on the environment.
Which of the following has the minimum atomic mass?
If hydrogen is on the list, it automatically wins.
The hydrogen-to-helium ratio is an important piece of evidence for the big bang What is the minimum hydrogen-to-helium ratio observed?
The minimum hydrogen-to-helium ratio observed is approximately 25% hydrogen to 75% helium. This ratio is consistent with predictions based on the conditions of the early universe during the Big Bang.
What is the minimum number of hydrogen atoms present in a carboxylic ester?
The minimum number of hydrogen atoms present in a carboxylic ester is two: one hydrogen atom attached to the oxygen in the ester functional group and one hydrogen atom on the carbon atom adjacent to the ester group.
What is the minimum energy required to break an HCl molecule into a hydrogen atom?
To break an HCl molecule into a hydrogen atom and a chlorine atom, the minimum energy required is equal to the bond dissociation energy of the H-Cl bond, which is approximately 432 kilojoules per mole.
What is the minimum amount of valence electrons an atom can have?
To answer this, we simply need to consider the lightest of the chemical elements, hydrogen. Hydrogen's atomic number, and thus its number of protons and electrons, is 1. So, by necessity, that is the minimum amount of valence electrons an atom can have.
What is the minimum number of covalent bonds that hydrogen atom can form?
Hydrogen can only form one covalent bond because it has one valence electron to share with another atom.
What temperature does a star start to fuse hydrogen?
The temperature at which hydrogen fuses is 10,000,000 degrees Kelvin. This is the minimum temperature the core of a proto star has to have to become a true star.
Why hydrogen not automatically burnt in air?
Hydrogen does not burn at room temperature because there is a minimum activation energy that must be reached to initiate the reaction. This is the energy needed to break the existing bonds withing the molecules, allowing the atoms to rearrange.
What is minimum toxic concentration?
Minimum toxic concentration (MTC) refers to the lowest concentration of a substance in a biological system that produces a toxic effect. It is a critical value in toxicology, helping to determine safe exposure levels for chemicals, drugs, or environmental pollutants. Understanding MTC is essential for assessing risks and ensuring safety in various applications, including pharmaceuticals and environmental health.
